本技能提供阿里巴巴Java开发手册中的异常处理和日志相关规范。
【强制】不要通过catch方式处理可预检查的RuntimeException（如NullPointerException、IndexOutOfBoundsException）
if (obj != null) {...}try { obj.method() } catch (NullPointerException e) {…}【强制】异常不要用来做流程控制、条件控制
【强制】catch时区分稳定代码和非稳定代码，对非稳定代码尽可能区分异常类型
【强制】捕获异常是为了处理它，不要捕获却什么都不处理
【强制】try块在事务代码中，catch异常后需要回滚事务时必须手动回滚
【强制】finally块必须对资源对象、流对象进行关闭，有异常也要做try-catch
【强制】不要在finally块中使用return
【强制】捕获异常与抛异常必须完全匹配，或捕获异常是抛异常的父类
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
private static final Logger logger = LoggerFactory.getLogger(Abc.class);
【强制】trace/debug/info级别日志必须使用条件输出或占位符方式
if (logger.isDebugEnabled()) {
logger.debug("Processing trade with id: " + id);
}
logger.debug("Processing trade with id: {} ", id);
【强制】避免重复打印日志，在log4j.xml中设置additivity=false
【强制】异常信息应包括案发现场信息和异常堆栈信息
【推荐】生产环境禁止输出debug日志；有选择地输出info日志；谨慎使用warn级别
【推荐】使用warn日志级别记录用户输入参数错误，非必要不使用error级别
【强制】velocity调用POJO类属性时直接使用属性名，模板引擎会自动调用getXxx()
【强制】后台输送给页面的变量必须加$!{var}
System.currentTimeMillis(); 而不是 new Date().getTime();
