Part 1: Project Setup

Step 1: Create Spring Boot Project

Use Spring Initializr or create manually:

<!-- pom.xml -->
<project>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.2.0</version>
    </parent>
    
    <dependencies>
        <!-- Spring Boot Web -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        <!-- Astra DB Spring Boot Starter -->
        <dependency>
            <groupId>com.datastax.astra</groupId>
            <artifactId>data-api-spring-boot-3x-starter</artifactId>
            <version>1.5.1</version>
        </dependency>
        
        <!-- Lombok (optional, for cleaner code) -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        
        <!-- Validation -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-validation</artifactId>
        </dependency>
    </dependencies>
</project>

Step 2: Configure Astra DB Connection

Create application.yml:

spring:
  application:
    name: astra-spring-demo

astra:
  data-api:
    # Database connection
    token: ${ASTRA_DB_TOKEN}
    endpoint-url: ${ASTRA_DB_ENDPOINT}
    keyspace: ${ASTRA_DB_KEYSPACE:default_keyspace}
    
    # Schema management
    schema-action: CREATE_IF_NOT_EXISTS
    
    # Logging (development)
    log-request: ${ASTRA_LOG_REQUESTS:false}
    
    # Advanced options
    options:
      # Timeouts (milliseconds)
      timeout:
        connect: 5000
        request: 10000
        general: 30000
        collection-admin: 60000
      
      # HTTP configuration
      http:
        retry-count: 3
        retry-delay: 100
        version: HTTP_2
      
      # Embedding API key for vector search
      embedding-api-key: ${OPENAI_API_KEY:}

# Logging configuration
logging:
  level:
    com.datastax.astra: ${ASTRA_LOG_LEVEL:INFO}
    com.datastax.astra.client.DataAPIClient: ${ASTRA_LOG_LEVEL:INFO}

Environment Variables:

export ASTRA_DB_TOKEN="AstraCS:..."
export ASTRA_DB_ENDPOINT="https://your-db-id-region.apps.astra.datastax.com"
export ASTRA_DB_KEYSPACE="my_keyspace"
export OPENAI_API_KEY="sk-..."  # For vector search

Step 3: Main Application Class

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class AstraSpringDemoApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(AstraSpringDemoApplication.class, args);
    }
}

Part 2: Domain Model & Object Mapping

Understanding Object Mapping Annotations

The Astra DB SDK provides annotations for mapping Java objects to database collections:

Annotation	Purpose	Serialized As
`@DataApiCollection`	Defines collection and configuration	N/A
`@DocumentId`	Marks the document identifier	`_id`
`@Vectorize`	Auto-vectorization for semantic search	`$vectorize`
`@Lexical`	Full-text search indexing	`$lexical`
`@Vector`	Pre-computed vector embeddings	`$vector`

Step 4: Create Domain Model

package com.example.demo.model;

import com.datastax.astra.client.collections.mapping.*;
import com.datastax.astra.client.core.vector.SimilarityMetric;
import com.fasterxml.jackson.annotation.JsonProperty;
import jakarta.validation.constraints.*;
import lombok.Data;
import lombok.experimental.Accessors;

import java.time.Instant;
import java.util.Set;

@Data
@Accessors(chain = true)
@DataApiCollection(
    name = "products",
    // Vector search configuration
    vectorDimension = 1536,
    vectorSimilarity = SimilarityMetric.COSINE,
    vectorizeProvider = "openai",
    vectorizeModel = "text-embedding-ada-002",
    vectorizeSharedSecret = "OPENAI_API_KEY",
    // Full-text search
    lexicalEnabled = true,
    lexicalAnalyzer = AnalyzerTypes.ENGLISH,
    // Indexing optimization
    indexingDeny = {"internal_notes", "audit_log"}
)
public class Product {
    
    @DocumentId
    private String id;
    
    @NotBlank(message = "Name is required")
    @Size(min = 3, max = 100)
    private String name;
    
    @NotBlank(message = "Category is required")
    private String category;
    
    @NotNull(message = "Price is required")
    @Positive(message = "Price must be positive")
    private Double price;
    
    @Min(0)
    private Integer stock;
    
    @Vectorize
    private String description;  // Automatically vectorized
    
    @Lexical
    private String searchableText;  // Full-text search
    
    private Set<String> tags;
    
    @JsonProperty("created_at")
    private Instant createdAt;
    
    @JsonProperty("updated_at")
    private Instant updatedAt;
    
    // Not indexed
    private String internalNotes;
}

Key Points:

@DataApiCollection configures the collection
@DocumentId maps to _id in the database
@Vectorize enables semantic search
@Lexical enables full-text search
indexingDeny excludes fields from indexing

Part 3: Data Access Layer

Step 5: Create Repository Interface

package com.example.demo.repository;

import com.datastax.astra.spring.DataApiCollectionCrudRepository;
import com.example.demo.model.Product;
import org.springframework.stereotype.Repository;

@Repository
public interface ProductRepository 
    extends DataApiCollectionCrudRepository<Product, String> {
    
    // Spring Data methods are automatically available:
    // - save(entity)
    // - findById(id)
    // - findAll()
    // - deleteById(id)
    // - count()
    // - existsById(id)
    // 
    // Plus Query by Example and Data API filters
}

Step 6: Create Service Layer

package com.example.demo.service;

import com.datastax.astra.client.core.query.Filter;
import com.datastax.astra.client.core.query.Filters;
import com.example.demo.model.Product;
import com.example.demo.repository.ProductRepository;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.data.domain.*;
import org.springframework.stereotype.Service;

import java.time.Instant;
import java.util.List;
import java.util.Optional;

@Slf4j
@Service
@RequiredArgsConstructor
public class ProductService {
    
    private final ProductRepository repository;
    
    // Create
    public Product create(Product product) {
        product.setCreatedAt(Instant.now());
        product.setUpdatedAt(Instant.now());
        log.info("Creating product: {}", product.getName());
        return repository.save(product);
    }
    
    // Read
    public Optional<Product> findById(String id) {
        return repository.findById(id);
    }
    
    public List<Product> findAll() {
        return (List<Product>) repository.findAll();
    }
    
    // Update
    public Product update(String id, Product updates) {
        Product product = repository.findById(id)
            .orElseThrow(() -> new ResourceNotFoundException("Product not found: " + id));
        
        product.setName(updates.getName());
        product.setCategory(updates.getCategory());
        product.setPrice(updates.getPrice());
        product.setStock(updates.getStock());
        product.setDescription(updates.getDescription());
        product.setUpdatedAt(Instant.now());
        
        return repository.save(product);
    }
    
    // Delete
    public void delete(String id) {
        repository.deleteById(id);
    }
    
    // Query by Example
    public List<Product> findByCategory(String category) {
        Product probe = new Product().setCategory(category);
        return (List<Product>) repository.findAll(Example.of(probe));
    }
    
    // Data API Filters
    public List<Product> findInPriceRange(Double minPrice, Double maxPrice) {
        Filter filter = Filters.and(
            Filters.gte("price", minPrice),
            Filters.lte("price", maxPrice)
        );
        return (List<Product>) repository.findAll(filter);
    }
    
    // Pagination
    public Page<Product> findAllPaginated(int page, int size, String sortBy) {
        Pageable pageable = PageRequest.of(page, size, Sort.by(sortBy));
        return repository.findAll(Example.of(new Product()), pageable);
    }
    
    // Complex query
    public List<Product> searchProducts(String category, Double minPrice, Integer minStock) {
        List<Filter> filters = new java.util.ArrayList<>();
        
        if (category != null) {
            filters.add(Filters.eq("category", category));
        }
        if (minPrice != null) {
            filters.add(Filters.gte("price", minPrice));
        }
        if (minStock != null) {
            filters.add(Filters.gte("stock", minStock));
        }
        
        if (filters.isEmpty()) {
            return findAll();
        }
        
        Filter filter = filters.size() == 1 
            ? filters.get(0) 
            : Filters.and(filters.toArray(new Filter[0]));
            
        return (List<Product>) repository.findAll(filter);
    }
}

Part 4: REST API Layer

Step 7: Create REST Controller

package com.example.demo.controller;

import com.example.demo.model.Product;
import com.example.demo.service.ProductService;
import jakarta.validation.Valid;
import lombok.RequiredArgsConstructor;
import org.springframework.data.domain.Page;
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@RequestMapping("/api/products")
@RequiredArgsConstructor
public class ProductController {
    
    private final ProductService service;
    
    @GetMapping
    public List<Product> list() {
        return service.findAll();
    }
    
    @GetMapping("/paginated")
    public Page<Product> listPaginated(
            @RequestParam(defaultValue = "0") int page,
            @RequestParam(defaultValue = "20") int size,
            @RequestParam(defaultValue = "name") String sortBy) {
        return service.findAllPaginated(page, size, sortBy);
    }
    
    @GetMapping("/{id}")
    public Product get(@PathVariable String id) {
        return service.findById(id)
            .orElseThrow(() -> new ResourceNotFoundException("Product not found"));
    }
    
    @PostMapping
    @ResponseStatus(HttpStatus.CREATED)
    public Product create(@Valid @RequestBody Product product) {
        return service.create(product);
    }
    
    @PutMapping("/{id}")
    public Product update(@PathVariable String id, @Valid @RequestBody Product product) {
        return service.update(id, product);
    }
    
    @DeleteMapping("/{id}")
    @ResponseStatus(HttpStatus.NO_CONTENT)
    public void delete(@PathVariable String id) {
        service.delete(id);
    }
    
    @GetMapping("/category/{category}")
    public List<Product> byCategory(@PathVariable String category) {
        return service.findByCategory(category);
    }
    
    @GetMapping("/search")
    public List<Product> search(
            @RequestParam(required = false) String category,
            @RequestParam(required = false) Double minPrice,
            @RequestParam(required = false) Integer minStock) {
        return service.searchProducts(category, minPrice, minStock);
    }
    
    @GetMapping("/price-range")
    public List<Product> priceRange(
            @RequestParam Double min,
            @RequestParam Double max) {
        return service.findInPriceRange(min, max);
    }
}

Step 8: Error Handling

package com.example.demo.exception;

import com.datastax.astra.client.exceptions.DataAPIException;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;

import java.time.Instant;
import java.util.HashMap;
import java.util.Map;

@RestControllerAdvice
public class GlobalExceptionHandler {
    
    @ExceptionHandler(ResourceNotFoundException.class)
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public ErrorResponse handleNotFound(ResourceNotFoundException ex) {
        return new ErrorResponse(
            HttpStatus.NOT_FOUND.value(),
            ex.getMessage(),
            Instant.now()
        );
    }
    
    @ExceptionHandler(DataAPIException.class)
    @ResponseStatus(HttpStatus.SERVICE_UNAVAILABLE)
    public ErrorResponse handleDataAPIException(DataAPIException ex) {
        return new ErrorResponse(
            HttpStatus.SERVICE_UNAVAILABLE.value(),
            "Database error: " + ex.getMessage(),
            Instant.now()
        );
    }
    
    @ExceptionHandler(MethodArgumentNotValidException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public Map<String, String> handleValidationExceptions(
            MethodArgumentNotValidException ex) {
        Map<String, String> errors = new HashMap<>();
        ex.getBindingResult().getAllErrors().forEach((error) -> {
            String fieldName = ((FieldError) error).getField();
            String errorMessage = error.getDefaultMessage();
            errors.put(fieldName, errorMessage);
        });
        return errors;
    }
    
    record ErrorResponse(int status, String message, Instant timestamp) {}
}

class ResourceNotFoundException extends RuntimeException {
    public ResourceNotFoundException(String message) {
        super(message);
    }
}

  endpoints:
    web:
      exposure:
        include: health,info,metrics
  metrics:
    tags:
      application: ${spring.application.name}

Security

@Configuration
@EnableWebSecurity
public class SecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .authorizeHttpRequests(auth -> auth
                .requestMatchers("/health", "/actuator/**").permitAll()
                .requestMatchers("/api/**").authenticated()
            )
            .httpBasic();
        return http.build();
    }
}

Spring Boot Ecosystem Integration

Spring Boot DevTools

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <scope>runtime</scope>
    <optional>true</optional>
</dependency>

Spring Boot Actuator Metrics

@Component
public class DatabaseMetrics {
    
    private final MeterRegistry registry;
    private final ProductRepository repository;
    
    public DatabaseMetrics(MeterRegistry registry, ProductRepository repository) {
        this.registry = registry;
        this.repository = repository;
        
        Gauge.builder("products.count", repository, repo -> repo.count())
            .description("Total number of products")
            .register(registry);
    }
}

Spring Cache

@Configuration
@EnableCaching
public class CacheConfig {
    
    @Bean
    public CacheManager cacheManager() {
        return new ConcurrentMapCacheManager("products");
    }
}

@Service
public class ProductService {
    
    @Cacheable("products")
    public Optional<Product> findById(String id) {
        return repository.findById(id);
    }
    
    @CacheEvict(value = "products", key = "#id")
    public void delete(String id) {
        repository.deleteById(id);
    }
}

Spring Validation

@Data
public class Product {
    
    @NotBlank(message = "Name is required")
    @Size(min = 3, max = 100, message = "Name must be between 3 and 100 characters")
    private String name;
    
    @NotNull(message = "Price is required")
    @Positive(message = "Price must be positive")
    @DecimalMin(value = "0.01", message = "Price must be at least 0.01")
    private Double price;
    
    @Min(value = 0, message = "Stock cannot be negative")
    private Integer stock;
}

Spring Events

@Component
public class ProductEventListener {
    
    @EventListener
    public void handleProductCreated(ProductCreatedEvent event) {
        log.info("Product created: {}", event.getProduct().getName());
        // Send notification, update cache, etc.
    }
}

@Service
public class ProductService {
    
    @Autowired
    private ApplicationEventPublisher eventPublisher;
    
    public Product create(Product product) {
        Product saved = repository.save(product);
        eventPublisher.publishEvent(new ProductCreatedEvent(this, saved));
        return saved;
    }
}

Best Practices Summary

Use DTOs for API boundaries - Separate domain models from API contracts
Implement proper error handling - Use @RestControllerAdvice for global exception handling
Validate input - Use Bean Validation annotations
Paginate large results - Always use pagination for list endpoints
Index strategically - Only index fields you query on
Use environment-specific configs - Different settings for dev/prod
Monitor your application - Use Spring Boot Actuator
Test thoroughly - Unit tests for logic, integration tests for APIs
Secure your endpoints - Use Spring Security
Document your API - Use SpringDoc OpenAPI

Troubleshooting

Common Issues

Connection Timeout:

astra:
  data-api:
    options:
      timeout:
        connect: 10000  # Increase timeout

Schema Validation Errors:

astra:
  data-api:
    schema-action: CREATE_IF_NOT_EXISTS  # Auto-create collections

Performance Issues:

Use pagination for large datasets
Index only necessary fields
Enable caching for frequently accessed data
