spring aop 配置切面，记录系统异常存入log日志

1.spring.xml(这里主要配置了抛出异常后的操作after-throwing)

需要注意的地方以黄色标注，主要是几个切入点bean配置

<!-- 激活自动代理功能 -->
    <aop:aspectj-autoproxy proxy-target-class="true"/>
    <!-- 系统服务组件的切面Bean -->
    <bean id="aspectService" class="com.test.http.utils.AspectService"></bean> 
    <!-- AOP配置 -->
    <aop:config>
        <!-- 声明一个切面,并注入切面Bean,相当于@Aspect -->
        <aop:aspect id="simpleAspect" ref="aspectService">
            <!-- 配置一个切入点,相当于@Pointcut -->
            <aop:pointcut expression="execution(* com.test.http.ser..*(..))" id="simplePointcut"/>
            <aop:after-throwing pointcut-ref="simplePointcut" method="afterThrow" throwing="ex"/>
        </aop:aspect>
    </aop:config>

2.AspectService.java(此类为切面的具体实现类)

package com.test.http.utils;


import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.aspectj.lang.JoinPoint;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

public class AspectService {
    
    private final static Log log = LogFactory.getLog(AspectService.class);
    
    //配置抛出异常后通知,使用在方法aspect()上注册的切入点
    public void afterThrow(JoinPoint joinPoint, Exception ex){
        
        System.out.println("进入切面AfterThrowing方法中...");
        
        //判断日志输出级别
        if(log.isInfoEnabled()){
            log.info("afterThrow " + joinPoint + "	" + ex.getMessage());
        }
        //详细错误信息
        String errorMsg = "";
        StackTraceElement[] trace = ex.getStackTrace();
        for (StackTraceElement s : trace) {
            errorMsg += "	at " + s + "
";
        }
        System.out.println("具体异常信息："+errorMsg);
        
        System.out.println("afterThrow异常方法名 " + joinPoint + "	" + ex.getMessage());
        
        System.out.println("进入切面AfterThrowing方法结束！！！");
        
        //写入异常日志
        writeLog(errorMsg,joinPoint,ex);
        
    }
    
    
    /**
     * 
     * @param detailErrMsg 详细错误信息
     * @param method 方法名称
     * @Description: 日志异常
     * @author： Ma
     * @createTime： 2016-10-14
     */
    public void writeLog(String detailErrMsg,JoinPoint joinPoint,Exception ex){
        
        HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.
                getRequestAttributes()).getRequest(); 
        //获取请求的URL
        StringBuffer requestURL = request.getRequestURL();
        //获取参 数信息
        String queryString = request.getQueryString(); 
        //封装完整请求URL带参数
        if(queryString != null){  
            requestURL .append("?").append(queryString);  
        }
        
        String cla=joinPoint.getTarget().getClass().getName();//action
        String method=joinPoint.getSignature().getName();//method
        try{
            
            SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            //创建输出异常log日志
            File file =new File("d:/test/"+System.currentTimeMillis()+method+".log");
            //if file doesnt exists, then create it
            if(!file.exists()){
                file.createNewFile();
            }
            
            FileOutputStream out=new FileOutputStream(file,false); //如果追加方式用true        
            //日志具体参数
            StringBuffer sb=new StringBuffer();
            sb.append("-----------"+sdf.format(new Date())+"------------
");
            sb.append("远程请求URL["+requestURL+"]
");
            sb.append("接口方法：["+cla+"."+method+"]
");
            sb.append("详细错误信息："+ex+"
");
            sb.append(detailErrMsg+"
");
            out.write(sb.toString().getBytes("utf-8"));//注意需要转换对应的字符集
            out.close();
            
            System.out.println("Done");

         }catch(IOException e){
             e.printStackTrace();
         }
        
        
    }

}

3.创建测试类

public void testMethod(HttpServletRequest request){
      System.out.println("进入方法");
      //System.out.println(request.getParameter("username"));
      int i = 9 / 0;
}

4.运行后log日志情况
