SpringMVC记录我遇到的坑_AOP注解无效,切面不执行的解决

AOP注解无效,切面不执行的解决

想做一个api请求日志,想到使用aop,配置过程中遇到了一个坑,aop不起作用,

我的aop是这样的:

package com.ljwm.ibei.aspact; 
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes; 
import javax.servlet.http.HttpServletRequest;
 
/**
 * Created by user on 2017/9/8.
 */
@Aspect
@Configuration
public class ApiRequestLog { 
    private Logger _log = LoggerFactory.getLogger(ApiRequestLog.class); 
    @Around("execution(* com.ljwm.ibei.controller.*.*(..))")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        RequestAttributes ra = RequestContextHolder.getRequestAttributes();
        ServletRequestAttributes sra = (ServletRequestAttributes) ra;
        HttpServletRequest request = sra.getRequest();
 
        String url = request.getRequestURL().toString();
        String method = request.getMethod();
        String uri = request.getRequestURI();
        String queryString = request.getQueryString();
        _log.debug("请求开始, 各个参数, url: {}, method: {}, uri: {}, params: {}", url, method, uri, queryString);
        Object result = pjp.proceed();
        return result;
    }
}

配置文件分成applicationContext.xml、applicationContext-mvc.xml还有mybatis和shiro的

web.xml配置:


  Archetype Created Web Application
 
  
    shiroFilter
    org.springframework.web.filter.DelegatingFilterProxy
    
      targetFilterLifecycle
      true
    
  
  
    shiroFilter
    /*
  
  
    spring-dispatcher
    
      org.springframework.web.servlet.DispatcherServlet
    
    
      contextConfigLocation
      classpath:spring/applicationContext-mvc.xml
    
    1
  
  
    spring-dispatcher
    /
  
  
    contextConfigLocation
    classpath:spring/applicationContext*.xml
  
  
    characterEncodingFilter
    org.springframework.web.filter.CharacterEncodingFilter
    
      encoding
      UTF-8
    
    
      forceEncoding
      true
    
  
  
    characterEncodingFilter
    /*
  
  
    org.springframework.web.context.ContextLoaderListener
  
  
    org.springframework.web.context.request.RequestContextListener
  
  
    com.ljwm.ibei.listener.ContextFinalizer
  

我把写在applicationContext中,把写在applicationContext-mvc中,发现aop没有执行,后来经过尝试发现,因为在初始化DispatchServlet的时候加载了mvc的配置,但是aop的代理却没有加载,导致其不能执行,我猜测是因为spring默认bean是单例的,

对已经初始化的bean容器不在做后续处理,由于是先加载的mvc所以是aop失效,我把aop代理的那个放到mvc中,aop就能执行了,不知道我的猜测对不对,还望大神赐教

另一个问题:

springmvc在controller层使用aop切面不成功解决

需要在配置文件中加入

以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
