使用事務(wù)的時(shí)候,在DAO就不要用try{}catch{}了,因?yàn)樵赾atch里面捕獲的異常,spring的事務(wù)貌似不能去回滾
今天做了個(gè)aop的試驗(yàn),對(duì)于springmvc的action不能攔截成功,研究了很久,沒(méi)有找到問(wèn)題,所以請(qǐng)教下大家.
下面是代碼:
1.springmvc的action:
package com.sure.demo.web;
import java.util.Date;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class DemoTestAction extends MultiActionController {
//返回的test頁(yè)面
private String testPage;
public String getTestPage() {
return testPage;
}
public void setTestPage(String testPage) {
this.testPage = testPage;
}
/**
* test入口
* @param request
* @param response
* @return
* @throws Exception
*/
public ModelAndView test(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView mav = null;
mav = new ModelAndView(this.getTestPage());
request.setAttribute("test", new Date().toString());
return mav;
}
}
2.jsp代碼:
<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String test = (String)request.getAttribute("test");
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
當(dāng)前時(shí)間是:<%=test %> <br>
</body>
</html>
3.aop代碼:
package com.sure.aopdemo;
import org.aspectj.lang.JoinPoint;
public class AopDemoTestImpl {
public void afterTest(JoinPoint joinPoint) {
System.out.println("aop--執(zhí)行類(lèi):"+joinPoint.getThis()+"的"+joinPoint.getSignature().getName()+"方法之后");
}
public void beforeTest(JoinPoint joinPoint) {
System.out.println("aop--執(zhí)行類(lèi):"+joinPoint.getThis()+"的"+joinPoint.getSignature().getName()+"方法之前");
}
public void exceptionTest() {
System.out.println("aop方法異常");
}
}
