Data garbled during form submission:
For get method submission:
Find the server. xml in the conf folder under the tomcat installation path, and click <Connector> Add URIEncoding = "UTF-8". See the red text section.
<Connector port = "8080" protocol = "HTTP/1.1"
ConnectionTimeout = "20000"
RedirectPort = "8443" URIEncoding = "UTF-8"/>
This method is only applicable to the get method.
For the post method:
There are several solutions,
① Add the following code to the jsp page: request. setCharacterEncoding ("UTF-8"); sometimes you need to add respon. setCharacterEncoding ("UTF-8 ");
② Use a filter (recommended ):
Add a new PageEncodingFilter class under the src folder of the project. The Code is as follows:
Chinese filter code:
Package com. util;
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;
Import javax. servlet. http. HttpServletRequest; // The class used above
// Three methods of Chinese filter, one attribute
Public class PageEncodingFilter implements Filter {
Private String encode;
// Initialization. The initial value of encoding comes from "web. xml ".
Public void init (FilterConfig arg0) throws ServletException {
This. encode = arg0.getInitParameter ("encoding ");
}
// Perform Filtering
Public void doFilter (ServletRequest arg0, ServletResponse arg1,
FilterChain arg2) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) arg0; // strong conversion to HttpServletRequest
Request. setCharacterEncoding (encode); // The encode parameter is String. Do not add "Double quotation marks"
Arg2.doFilter (arg0, arg1 );
}
// Destroy
Public void destroy (){
This. encode = null;
}
}
Note:
// Creation steps:
1. Create a new class to implement the interface Filter (the package contains "javax. servlet. Filter", which varies slightly according to the "MyEclips" version );
2. modify the code as above;
3. Open the web. xml file (this file is in webRoot/WEB-INF/web. xml) and configure as follows.
Configuration code:
<! -- Chinese filter initialization parameter settings -->
<Filter>
<Filter-name> PageEncodingFilter </filter-name> <! -- Filter Name -->
<Filter-class> org. ty. struts. util. PageEncodingFilter </filter-class> <! -- Filter file location -->
<Init-param>
<Param-name> encoding </param-name> <! -- Initial Parameter Name, specifying the sequence set used by the jsp page -->
<Param-value> UTF-8 </param-value> <! -- Initial Parameter Value, specifying the Chinese sequence set -->
</Init-param>
</Filter>
<! -- Filter ing path configuration -->
<Filter-mapping>
<Filter-name> PageEncodingFilter </filter-name>
<Url-pattern>/* </url-pattern> <! -- Filter all directories in Chinese -->
</Filter-mapping>
Garbled jsp page:
Add the following code to the jsp code:
<% @ Page language = "java" import = "java. util. *" pageEncoding = "UTF-8" %>
Html files
Add the following code to the head header:
<Head>
<Meta http-equiv = "content-type" content = "text/html; charset = UTF-8">
</Head>
