post提交解决办法
1、web.xml中添加
<filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> 过滤器中需要的俩参数encoding和forceEncoding，需要配置属性值 <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>encoding</filter-name> <servlet-name>springmvc</servlet-name> </filter-mapping>
2、html页面制定utf-8
<head>
<meta charset="UTF-8">
</head>
get方式请求的乱码，还需要在tomcat的8080端口添加
URIEncoding="UTF-8"
