SpringMVC get请求乱码（Tomcat服务器）

在使用get请求的时候，我们得参数如果有中文将会出现乱码的情况；

以下是解决该问题的步骤；

（1）在项目的web.xml添加以下过滤器：

<filter>
        <filter-name>characterEncoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

（2）修改tomcat服务器的server.xml文件，

修改前：

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               acceptCount="2000"
               maxHttpHeaderSize="8192"
               maxThreads="4000"
               minSpareThreads="1000"
               redirectPort="8443" />

修改后：

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               acceptCount="2000"
               maxHttpHeaderSize="8192"
               maxThreads="4000"
               minSpareThreads="1000"
               redirectPort="8443"

              URIEncoding="UTF-8"/>

也就是在Connector中添加了   URIEncoding="UTF-8"
