Garbled code in JSP front-end data transmission to backend

Document directory

• 1. filter class:
• 2. Web. xml file:

Solution:

Set a filter in the background to filter and convert the encoding!

The procedure is as follows:

 

 

1. filter class:

Public class loggerfilter implements filter {
Private string encoding = "GBK ";
Private filterconfig fiterconfig = NULL;

Public void destroy (){
}

Public void dofilter (servletrequest request, servletresponse response,
Filterchain) throws ioexception, servletexception {


This. Encoding = fiterconfig. getinitparameter ("encoding ");
If (this. Encoding = NULL ){
Encoding = "GBK ";
}
Request. setcharacterencoding (this. Encoding );
Response. setcharacterencoding (this. Encoding );
Filterchain. dofilter (request, response );
}

Public void Init (filterconfig) throws servletexception {

 

}

 

2. Web. xml file:

<Filter>
<Filter-Name> loggerfilter </filter-Name>
<Filter-class> cn.com. sinosoft. Filter. loggerfilter </filter-class>
</Filter>
<Filter-mapping>
<Filter-Name> loggerfilter </filter-Name>
<URL-pattern> *. DO </url-pattern>
</Filter-mapping>
