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 + "\t" + ex.getMessage()); } //详细错误信息 String errorMsg = ""; StackTraceElement[] trace = ex.getStackTrace(); for (StackTraceElement s : trace) { errorMsg += "\tat " + s + "\r\n"; } System.out.println("具体异常信息："+errorMsg); System.out.println("afterThrow异常方法名 " + joinPoint + "\t" + 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())+"------------\r\n"); sb.append("远程请求URL["+requestURL+"]\r\n"); sb.append("接口方法：["+cla+"."+method+"]\r\n"); sb.append("详细错误信息："+ex+"\r\n"); sb.append(detailErrMsg+"\r\n"); 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

其它切面皆可同等配置如图：
