Java Read database Chinese information, why in the JSP page garbled

There are several workarounds:

1, ensure that the character encoding of the project and each JSP page character encoding consistent, if inconsistent may lead to Chinese garbled problem <%@ page language= "java" contenttype= "text/html; Charset=utf-8 "pageencoding=" UTF-8 "%>
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 ">
2, write the filter filter, in the filter method Dofilter
Request.setcharacterencoding ("UTF-8");

Response.setcontenttype ("Text/html;charset=utf-8");

Configure the following information in Web. XML to filter all requests
<filter>
<filter-name>characterFilter</filter-name>
<filter-class> Custom Filter Class full-qualified class name </filter-class>
</filter>
<filter-mapping>
<filter-name>characterFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
3. Adding JSP configuration information to Web. xml
<jsp-config>
<jsp-property-group>
<description> for config the Web application </description>
<display-name>JSPConfiguration</display-name>
<url-pattern>*.jsp</url-pattern>
<el-ignored>false</el-ignored>
<page-encoding>UTF-8</page-encoding>
</jsp-property-group>
</jsp-config>
In the JSP
<%@ page language= "java" contenttype= "text/html; Charset=utf-8 "pageencoding=" UTF-8 "%>
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 ">
The above three methods can be implemented, the second option is recommended, for any request, JSP and servlet can solve the Chinese problem
