简介

　　提交参数和返回数据会乱码，即request.setChrarcterEncoding()和response.setCharacterEncoding()没有设置

 

解决

　　SpringMVC中处理

　　1. 提交参数乱码，通过设置过滤器解决

<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>

 

　　2. 响应乱码，通过@RequestMapping(product="(content-type)")解决

@RequestMapping(value = "/spring2",method = RequestMethod.GET,produces = "text/html;charset=utf-8")
