Java garbled Processing

Tomcat configuration code:

Locate the server. XML for conf In the Tomcat directory and add uriencoding = "UTF-8" to the connector Node"

<Connector Port = "80" maxhttpheadersize = "8192" maxthreads = "150"
Minsparethreads = "25" maxsparethreads = "75" enablelookups = "false"
Redirectport = "8443" acceptcount = "100" connectiontimeout = "20000"
Disableuploadtimeout = "true"Uriencoding = "UTF-8 "/>

Use global Filter

 Package  Com. bjdata. Favorite. servlet;  Import  Java. Io. ioexception;  Import  Javax. servlet. filter;  Import Javax. servlet. filterchain;  Import  Javax. servlet. filterconfig;  Import  Javax. servlet. servletexception;  Import  Javax. servlet. servletrequest;  Import  Javax. servlet. servletresponse;  Public   Class Globalfilter Implements  Filter {  Public  Void  Destroy (){}  Public   Void  Dofilter (servletrequest request, servletresponse response, filterchain chain)  Throws  Ioexception, servletexception {request. setcharacterencoding ( UTF-8 "); //  Set Encoding  Chain. dofilter (request, response );}  Public   Void Init (filterconfig)Throws  Servletexception {}} 

Configure Filter

<? XML version = "1.0" encoding = "UTF-8"?> <Web-app version = "2.4" xmlns = "http://java.sun.com/xml/ns/j2ee"Xmlns: xsi= "Http://www.w3.org/2001/XMLSchema-instance"Xsi: schemalocation= "Http://java.sun.com/xml/ns/j2ee http://Java.sun.com/xml/ns/j2ee/web-app_2_4.xsd "><Filter> <filter-Name> globalfilter </filter-Name> <filter-Class> Com. bjdata. Favorite. servlet. globalfilter </filter-Class> </Filter> <filter-mapping> <filter-Name> globalfilter </filter-Name> <URL-pattern>/*</Url-pattern> </filter-mapping> </Web-app>
 

 

Configure encoding in struts

 
<? XML version = "1.0" encoding = "UTF-8"?> <! Doctype struts public "-// Apache Software Foundation // DTD struts configuration 2.1 // en" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <constant name = "struts. i18n. encoding "value =" UTF-8 "/> </struts>
 

Garbled characters are returned in JSON format:

Response. setcharacterencoding ("UTF-8 ");
