Spring MVC 项目搭建 -4- spring security-添加自定义登录页面

修改配置文件

<!--spring-sample-security.xml-->

<!-- 去除不需要拦截的url -->
<http pattern="/libs/**" security="none"/>
<http pattern="/login.html" security="none" />
<http pattern="/resources/**" security="none" />
<!-- 配置一层拦截,需要输入正确用户名密码才能访问网站 -->
<http auto-config="true" >
    <!-- 拦截不是ROLE_USER的请求 -->
    <intercept-url pattern="/*" access="ROLE_USER" />
    <!-- 登录配置 -->
    <form-login login-page="/login.html"
        default-target-url="/test/mytest/loginSuccess"
        authentication-failure-url="/test/mytest/loginFaild"/>
    <!--退出登录配置-->
    <logout invalidate-session="true"
        logout-success-url="/"
        logout-url="/j_spring_security_logout"/>
</http>  

添加登录成功失败处理器

//TestController

/**
 * 登录成功处理器
 * @return
 */
@RequestMapping(value="/loginSuccess",method=RequestMethod.GET)
public @ResponseBody boolean loginSuccess(){
    return true;
}
/**
 * 登录失败处理器
 * @return
 */
@RequestMapping(value="/loginFaild",method=RequestMethod.GET)
public @ResponseBody boolean loginFaild(){
    return false;
}

添加页面
