Sping AOP用AspectJ注解的方式拦截不到SpringMVC的controller方法？

Sping AOP用AspectJ注解的方式拦截不到SpringMVC的controller方法怎么办？

下面是本人做的一个拦截小栗子：

环境：jdk1.7 ,spring 4.1.5

Eclipse项目代码结构：

配置

1.首先pom.xml配置文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion>

</project>

2.applicationContext.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd"
default-lazy-init="false">

<description>Spring公共配置 </description>

<!-- 使用annotation 自动注册bean, 并保证@Required、@Autowired的属性被注入 -->
<context:component-scan base-package="com.zone">
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
</beans>

3.spring-mvc.xml 

特别说明：

<!-- 启动AspectJ支持 -->
<aop:aspectj-autoproxy proxy-target-class="true" />

配置(重要)请在 spring-mvc.xml中添加，原因请参考这里

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> <!-- 必须加上 -->
<mvc:annotation-driven />

<!-- 启动AspectJ支持 -->
<aop:aspectj-autoproxy proxy-target-class="true" />

<!-- 自动扫描且只扫描@Controller -->
<context:component-scan base-package="com.zone"
use-default-filters="false">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>

<!-- 视图 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>

<!-- 容器默认的DefaultServletHandler处理 所有静态内容与无RequestMapping处理的URL -->
<mvc:default-servlet-handler />
</beans>

4.log4j.xml用于控制台打印springmvc启动加载信息

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{HH:mm:ss}] %p - %C{1}.%M(%L) | %m%n" />
</layout>
</appender>
<appender name="DAILY" class="org.apache.log4j.DailyRollingFileAppender">
<param name="File"
value="/console.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd'.log'" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{HH:mm:ss}] %p - %C{1}.%M(%L) | %m%n" />
</layout>
</appender>
<root>
<level value="info" />
<appender-ref ref="CONSOLE" />
<appender-ref ref="DAILY" />
</root>
</log4j:configuration>

5.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

代码

1.登录的controller：LoginController.java

package com.zone.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import com.zone.annotation.RequestLimit;

/**
*
*
* @author zgzi
* @version [版本号, 2015年12月4日]
* @see [相关类/方法]
* @since [产品/模块版本]
*/

@Controller
@RequestMapping("/account")
public class LoginController
{
/**
* 加入注解@RequestLimit 被拦截
*
* @param username
* @param request
* @return
* @see [类、类#方法、类#成员]
*/
@RequestMapping(value = "/login", method = RequestMethod.POST)
@RequestLimit
public String login(@RequestParam(value = "username") String username, HttpServletRequest request)
{
request.setAttribute("username", username);
return "loginSuccess";
}
}

2.自定义注解：RequestLimit.java

//自定义注解
package com.zone.annotation;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
@Documented
public @interface RequestLimit
{
/**
*
* 允许访问的次数，默认值MAX_VALUE
*/
int count() default Integer.MAX_VALUE;
}

3.测试拦截：AOPInterceptTest.java

package com.zone.aop;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.stereotype.Component;

import com.zone.annotation.RequestLimit;

@Aspect
@Component
public class AOPInterceptTest
{
/**
* 拦截登录
*
* @param joinPoint
* @param limit
* @return
* @throws Throwable
* @see [类、类#方法、类#成员]
*/
@Around("within(@org.springframework.stereotype.Controller *) && @annotation(limit)")
public Object requestLimit(final ProceedingJoinPoint joinPoint, RequestLimit limit)
throws Throwable
{
Object[] args = joinPoint.getArgs();
if(args[0].equals("zone"))
{
return "loginFailed";
}
return joinPoint.proceed();
}
}

最后简单页面：

1.index.jsp:

<html>
<body>
<h2>Hello World!</h2>
<h2>Dear friends ,use "zone" to login must be Intercepted.</h2>
<form action="account/login" method="post">
<input type="text" name="username" /> <input type="submit"
value="submit">
</form>
<div id="errorDiv">

</div>
</body>
</html>

下面页面都放置于

/SpringMVCAOP/src/main/webapp/WEB-INF/jsp/ 下

2.登录被拦截页面：loginFailed.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Login Success</title>
</head>
<body>
<p style="color:red;font-size: 16px;">Zone was  Intercepted.
</body>
</html>

3.登录成功页面：loginSuccess.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Login Success</title>
</head>
<body>
Hello
<span style="color: red;">${username}</span> ,Welcome to spring mvc
aop, I know you are not zone.
</body>
</html>

总结这样一个小小的Spring mvc aop拦截测试就ok了？项目代码下载请参考这里，不过全部代码都已在上面贴出来了。
有人会说spring mvc 已经提供了拦截器何必要自己配置aop去拦截哪？哈哈，闹着玩呗》》
