SpringMvc 传参中文乱码

produces="application/json;charset=UTF-8"

@RequestMapping(value="/方法名",produces="application/json;charset=UTF-8")

Tomcat文件 service.xml

原来

<Connector port="8080" protocol="HTTP/1.1"

   connectionTimeout="20000"

   redirectPort="8443"/>

加一个URIEncoding="UTF-8"

<Connector port="8080" protocol="HTTP/1.1"

   connectionTimeout="20000"

   redirectPort="8443"

   URIEncoding="UTF-8"/>
