SpringSecurity实现后台管理员登录（二）

需求：login.ftl页面中登录成功后进入index.ftl页面中

一、pom.xml中添加json转换相关的包

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.4.4</version>
  </dependency>
  <dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.4.4</version>
  </dependency>
  <dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.4.4</version>
  </dependency>

二、applicationContext-mvc.xml中添加json转换相关的配置

<!--token 拦截校验 -->
  <mvc:annotation-driven content-negotiation-manager="contentNegotiationManager" />
  <bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false" />
    <property name="favorParameter" value="true" />
    <property name="ignoreAcceptHeader" value="false" />
    <property name="mediaTypes">
      <value>
        atom=application/atom+xml
        html=text/html
        json=application/json
        *=*/*
      </value>
    </property>
  </bean>

三、applicationContext-security.xml中

将<intercept-url pattern="/service/index/index"access="ROLE_AUTHORITY"/>

改为<intercept-url pattern="/service/index/index" />

这里只是要实现简单的登录功能，所以没有设计权限。加了access=” "ROLE_AUTHORITY”会导致无法登录。

四、实现效果
