考虑项目安全需求，将http请求转为https，项目中已集成的shiro框架已实现SSL登陆，来看下具体实现吧。

tomcat的server.xml文件配置。将http的8080端口调转到https的8443端口

<Connector acceptCount="500" connectionTimeout="20000" enableLookups="false" maxThreads="400" port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8" redirectPort="8443"/>

<Connector SSLEnabled="true" acceptCount="500" clientAuth="false" keystoreFile="D:\localhost.keystore" keystorePass="aerors123" maxThreads="400" port="8443" protocol="HTTP/1.1" scheme="https" secure="true" sslProtocol="TLS"/>

applicationContext.xml中添加shiro相关配置

<bean id="sslFilter" class="org.apache.shiro.web.filter.authz.SslFilter">
        <property name="port" value="8443" />
    </bean>

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
    <!-- securityManager -->
    <property name="securityManager" ref="securityManager" />
    <!-- 登录路径 -->
    <property name="loginUrl" value="/login.jsp" />
    <!-- 登录成功后跳转路径 -->
    <property name="successUrl" value="/index.jsp" />
    <!-- 授权失败跳转路径 -->
    <property name="unauthorizedUrl" value="/login.jsp" />
    <property name="filters">
        <util:map>
            <entry key="authc" value-ref="formAuthenticationFilter" />
            <entry key="sysUser" value-ref="sysUserFilter" />
            <entry key="kickout" value-ref="kickoutSessionControlFilter" />
            <entry key="ssl" value-ref="sslFilter" />
        </util:map>
    </property>
    <!-- 过滤链定义 -->
    <property name="filterChainDefinitions">
        <value>
            /login.jsp = ssl,anon
            /logout = logout
            /*.js = anon
            /*.css = anon
            /error.jsp= anon
            /mapdaohang.jsp= anon
            /unauthor.jsp= anon
            <!-- authc表示需要认证的链接 -->
            /lost.jsp = kickout,authc,roles["lost"]
            /*.jsp = kickout,authc
        </value>
    </property>
</bean>

在filters中添加<entry key="ssl" value-ref="sslFilter" />即可在filterChainDefinitions中直接引用.
