spring使用AOP和自定义注解功能添加日志管理--实用

1、首先创建注解Log类：

@Target({ElementType.PARAMETER, ElementType.METHOD})  

@Retention(RetentionPolicy.RUNTIME)  

@Documented  

public @interface Log {

public String operationType() default "";  

public String operationName() default "";

}

2、创建Aspect切面类SystemLogAspect

@Aspect  //此处注解需要在springMVC xml配置文件设置

@Component

public class SystemLogAspect {

private  static  final Logger logger = Logger.getLogger(SystemLogAspect. class);

public SystemLogAspect(){

System.out.println("**************SystemLogAspect****************");

}

@Pointcut("@annotation(com.iflytek.epdcloud.  

public  void controllerAspect() {

}

private String getUserNamer(){

String username="";

HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();

username =request.getSession().getAttribute(Const.SESSION_USERNAME).toString();

return username;

}

 

@Before("controllerAspect()")

public void before(JoinPoint joinPoint) {

logger.info("开始before>>>>>" + joinPoint);

logger.info("username>>>>>"+getUserNamer());

logger.info("type>>>>>"+getType(joinPoint));

logger.info("name>>>>>"+getName(joinPoint));

}    

 

@After("controllerAspect()")  

public  void after(JoinPoint joinPoint) {

logger.info("username>>>>>"+getUserNamer());

logger.info("type>>>>>"+getType(joinPoint));

logger.info("name>>>>>"+getName(joinPoint));

logger.info("结束after>>>" + joinPoint);

}

@AfterThrowing("controllerAspect()")

public void error(JoinPoint joinPoint){

logger.info("抛出异常error>>>" + joinPoint);

logger.info("username>>>>>"+getUserNamer());

logger.info("type>>>>>"+getType(joinPoint));

logger.info("name>>>>>"+getName(joinPoint));

}

private String getName(JoinPoint joinPoint) {  

MethodSignature methodName = (MethodSignature)joinPoint.getSignature();  

Method method = methodName.getMethod();  

return method.getAnnotation(Log.class).operationName();  

} 

private String getType(JoinPoint joinPoint) {  

MethodSignature methodName = (MethodSignature)joinPoint.getSignature();  

Method method = methodName.getMethod();  

return method.getAnnotation(Log.class).operationType();  

} 

}

3、在springMVC 配置文件xml配置相关参数如下；

4、在controller类使用实例说明：

@Log(operationType=Const.QUERY,operationName="获取用户对象")

@RequestMapping(value="/getUserById/{id}",method=RequestMethod.GET)

public PageData getUserById(@PathVariable("id") String id) throws Exception{

PageData pd = this.getPageData();

pd.put("USER_ID", id);

return  userService.findById(pd);

}

5、运行效果如下图：
