Process Chinese characters correctly when submitting the form (tomcat + jsp)

Step 3:

1. About 50 lines in conf/server. xml under the tomcat installation directory:

(Red configuration)

<Connector port = "8088" protocol = "HTTP/1.1"
ConnectionTimeout = "20000"
RedirectPort = "8443"
URIEncoding = "UTF-8"/>

2. Add a class that implements the javax. servlet. Filter interface

And rewrite its doFilter method:

Public void doFilter (ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
Request. setCharacterEncoding ("UTF-8 ");
Chain. doFilter (request, response );

 }

3. Use the filter in web. xml

<Filter>
<Filter-name> characterfilter </filter-name>
<Filter-class> com. huicer. demo. filter. CharacterFilter </filter-class>
</Filter>
<Filter-mapping>
<Filter-name> characterfilter </filter-name>
<Url-pattern>/* </url-pattern>
</Filter-mapping>

The user name and password can be set to Chinese.
