Solve Chinese garbled characters in Ajax loading JSon data, ajaxjson

I. Problem Description

When I use zTree to asynchronously refresh the parent menu, the server returns Chinese garbled characters, but SpringMvc is used in the project and Chinese garbled characters have been processed. Why?

Configuration of asynchronous requests:

Java code

async: {   enable: true,   url: basePath + '/sysMenu/listSysMenu',   autoParam: ["id=parentId"] } 

SpringMvc Chinese Character Processing:

Java code

<mvc:annotation-driven>   <mvc:message-converters>   <bean class="org.springframework.http.converter.StringHttpMessageConverter">     <property name="supportedMediaTypes">        <list>           <value>application/json;charset=UTF-8</value>       <value>text/html;charset=UTF-8</value>      </list>     </property>   </bean>  </mvc:message-converters> </mvc:annotation-driven> 

The returned results contain Chinese garbled characters:

Js Code

[   {     "menuId": "880095098165986816",     "menuName": "????",     "parentId": "880095098165986815",     "menuUrl": "http://localhost:8080/imovie-manage/sysMenu/listSysMenuUI",     "menuIcon": "",     "menuSort": 1,     "isEnable": 1,     "parentMenuName": "??",     "id": "880095098165986816",     "name": "????",     "pId": "880095098165986815"   },   {     "menuId": "880095098165986817",     "menuName": "???????",     "parentId": "880095098165986815",     "menuUrl": "http://localhost:8080/imovie-manage/sysMenu/treeSysMenuUI",     "menuIcon": "",     "menuSort": 1,     "isEnable": 1,     "parentMenuName": "??",     "id": "880095098165986817",     "name": "???????",     "pId": "880095098165986815"   } ] 

Ii. Solutions

After investigation, it is found that supportedMediaTypes for SpringMvc Chinese Character Processing is missing one type.

The browser sends the following requests:

Asynchronous refresh uses a post request, but the Content-Type returned from the server is: text/plain; charset = ISO-8859-1

Charset is ISO-8859-1, rather than UTF-8, and SpringMvc handles Chinese garbled characters that do not contain this type, so it causes Chinese garbled characters.

Therefore, the final solution is to add the text/plain type to SpringMvc Chinese processing, as follows:

Java code


The details are as follows:

Java code

<property name="supportedMediaTypes">   <list>     <value>application/json;charset=UTF-8</value>   <value>text/html;charset=UTF-8</value>   <value>text/plain;charset=UTF-8</value>   </list> </property>
