2.添加Spring Security配置
<b:beans xmlns="http://www.springframework.org/schema/security" xmlns:b="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security.xsd"> <http /> <user-service> <user name="user" password="password" authorities="ROLE_USER" /> </user-service> </b:beans>
3.启用Spring Security：
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <!-- - Location of the XML file that defines the root application context - Applied by ContextLoaderListener. --> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/spring/*.xml </param-value> </context-param> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- - Loads the root application context of this web app at startup. - The application context is then available via - WebApplicationContextUtils.getWebApplicationContext(servletContext). --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
4.新建文件：src/main/webapp/index.jsp
<body>
<div class="container">
<h2>This is secured!</h2>
<p>
Hello <b><c:out value="${pageContext.request.remoteUser}"/></b>
</p>
<c:url var="logoutUrl" value="/logout"/>
<form class="form-inline" action="${logoutUrl}" method="post">
<input type="submit" value="Log out" />
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
