SpringAOP----捕捉异常存进数据库，方便找到问题

在日常开发的时候，有时候会出错，这个时候如果去看日志，会有一大堆日志查找很困难，所以就用spring的Aop来捕捉异常，存进数据库

切入点

加上一些信息，方便更加快速定位错误信息

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.METHOD})
@Documented
public @interface LogAnnotation {
    /**
     * 模块
     */
    public String title() default " ";
    /**
     * 功能
     */
    public BusinessType businessTyp() default BusinessType.INSERT;

}

@Aspect
@Component
public class LogExceptionAspectj extends RuntimeException{
    @Autowired
    private ExceptionHandleService exceptionHandleService;

    @AfterThrowing(value = "@annotation(com.twoblog.twoblogmaster.annotation.LogAnnotation)",throwing = "e")
    public void exceptionHandle(JoinPoint joinPoint,Exception e){
        //获取异常类型
        String exceptionType = e.getClass().getName();
        //获取异常信息
        String message = ExceptionUtil.getMessage(e);
        //获取异常的参数
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        LogAnnotation annotation = signature.getMethod().getAnnotation(LogAnnotation.class);
        BusinessType businessType = annotation.businessTyp();
        String s = businessType.toString();
        String title = annotation.title();
        //获取到出错的路径
        String errorPath = joinPoint.getTarget().getClass().getName()+"."+signature.getName();
        ExceptionHandle build = ExceptionHandle.builder().message(message).methodTitle(title).methodFunction(s).exceptionType(exceptionType).exceptionPath(errorPath).build();
        exceptionHandleService.save(build);
    }
}
