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：
