问题

springMVC中后台获取前台传递的参数发生乱码

解决

1.get方式发生乱码

修改tomcat中的server.xml配置文件，添加 URIEncoding="utf-8"

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

2.post方式发生乱码

在springMVC项目的web.xml中添加编码过滤器

    <filter>
        <filter-name>CharacterEncodingFilter</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>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
