SpringMVC---控制器接收到的中文数据乱码

spring MVC中默认的编码格式为“ISO-8859-1”，页面一般数据格式设置为UTF-8,所以导致了乱码

method=POST时

在web.xml中配置Spring字符过滤器，添加：

<!-- Spring字符集过滤器 -->
    <filter>
        <filter-name>SpringEncodingFilter</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>SpringEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

method=GET时

在tomcat的server.xml添加URIEncoding=“utf-8”

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
 
变更为：
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="utf-8"/>
