Method to Solve Encoding Issues When Passing Parameters in Spring MVC Shared

Summary

The issue of Chinese character encoding errors in socialism with Chinese characteristics is a problem we often encounter. There are many solutions, and this article introduces the one-time solution for Chinese character encoding errors in GET and POST methods.

Solution for Chinese character encoding errors in GET submissions

In the controller file with乱码, use the following method to convert the encoding to UTF-8

String str = new String(request.getParameter("parameterName").getBytes("iso-8859-1"), "utf-8");

Modify the server.xml file in the Tomcat server where the project is located

Modify

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1"redirectPort="8443"/>

Modified to:

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

The above method can still solve the Chinese garbled code problem in the GET method of Ajax requests.

Solution to the Chinese garbled code problem in POST submission

Add the following content to the web.xml file:

<!-- Filter to solve the problem of Chinese garbled code in POST submission, note that it can only solve the problem of Chinese garbled code in POST submission -->
 <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>
