无缺办理Tomcat 5.0.19中文乱码[Java编程]

1、Include的页面乱码

现象:include进来的页面呈现乱码,别的页面正常.

缘由:Tomcat在缺省情形下利用ISO-8859-1编码,但是在include时有时Tomcat不能精确按照外层.jsp文件的编码解析include进来的文件,造成include进来的文件中的中文乱码.

办理:这儿可以有很多办理办法,但是关于我们的中文环境,从根本上的办理办法是将Tomcat 5.0.19的核心缺省编码从ISO-8859-1改正成GBK .可以在下面地址下载改正过的jar文件,

jasper-compiler.jar,jasper-runtime.jar位于/common/lib下,别的位于/server/lib下,将新的.jar文件替换原.jar便可.

2、提交的数据乱码

现象:通过表单提交的数据呈现乱码.

缘由:缘由未明.大概是Tomcat在接纳到恳求后,并没有可以按照request中的信息提早精确的编码方法.

办理:可以增添一个设置字符集的Filter.

package filters;
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.UnavailableException;
public class SetCharacterEncodingFilter implements Filter {
　protected String encoding = null;
　protected FilterConfig filterConfig = null;
　protected boolean ignore = true;
　public void destroy() {
　　this.encoding = null;
　　this.filterConfig = null;
　}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
　// Conditionally select and set the character encoding to be used
　if (ignore || (request.getCharacterEncoding() == null)) {
　　String encoding = selectEncoding(request);
　　if (encoding != null)
　　　request.setCharacterEncoding(encoding);
　}
　// Pass control on to the next filter
　chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
　this.filterConfig = filterConfig;
　this.encoding = filterConfig.getInitParameter("encoding");
　String value = filterConfig.getInitParameter("ignore");
　if (value == null)
　　this.ignore = true;
　else if (value.equalsIgnoreCase("true"))
　　this.ignore = true;
　else if (value.equalsIgnoreCase("yes"))
　　this.ignore = true;
　else
　　this.ignore = false;
}
protected String selectEncoding(ServletRequest request) {
　return (this.encoding);
}
}

配置web.xml

<filter>
　<filter-name>Set Character Encoding</filter-name>
　<filter-class>filters.SetCharacterEncodingFilter</filter-class>
　<init-param>
　　<param-name>encoding</param-name>
　　<param-value>GBK</param-value>
　</init-param>
</filter>
<filter-mapping>
　<filter-name>Set Character Encoding</filter-name>
　<url-pattern>/*</url-pattern>
</filter-mapping>
