When jsp passes the value through the URL, the Chinese garbled problem can be solved in two ways

The first one is a bit troublesome

JSP page: var url = "AddPatrolAjax?domain=" +domain.value; //domain.value contains Chinese

服务器端：String domain = newString(request.getParameter("domain").getBytes( "ISO-8859-1"), "utf-8");

First get byte[], then newString(byte[], charset)

Second, you need to set tomcat

This sentence in tomcat's configuration file server.xml:

<Connector URIEncoding="GB2312"

port="8080"   maxHttpHeaderSize="8192"

               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

               enableLookups="false" redirectPort="8443" acceptCount="100"

               connectionTimeout="20000" disableUploadTimeout="true" />

 

Add this sentence: URIEncoding="UTF-8"

I have tested both of the above methods and can use
