    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>

</filter-mapping>

用postman输入中文参数调用，收到的都是乱码，必须手动把参数从iso8859-1转成utf-8

Answer 1

Try to modify the encoding settings of the servlet container. For tomcat, it is server.xml. In my impression

Answer 2

1.tomcat’s server.xml configuration

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

2. Inherit HttpServletRequestWrapper and override the getParameter method, and perform string encoding conversion in this method
