解决方案

我应该使用过滤器的解决这个问题。

 ＆LT;滤光器＆gt;
    ＆LT;过滤器名称＆gt;＆EncodingFilter LT; /过滤器名称＆gt;
    ＆LT;过滤器类和GT; myengineer.EncodingFilter＆LT; /过滤器级＆GT;
＆LT; /滤光器＆gt;
＆LT;过滤器映射＆GT;
    ＆LT;过滤器名称＆gt;＆EncodingFilter LT; /过滤器名称＆gt;
    ＆LT; URL模式＆GT; / *＆LT; / URL模式＆GT;
＆LT; /过滤器映射＆GT;

和java类过滤器

 包myengineer;

进口java.io.IOException异常;

进口javax.servlet.Filter的;
进口javax.servlet.FilterChain;
进口javax.servlet.FilterConfig;
进口javax.servlet.ServletException;

解决方案

I should use Filter for solve this problem.

    <filter>
    <filter-name>EncodingFilter</filter-name>
    <filter-class>myengineer.EncodingFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>EncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

and java class filter

package myengineer;

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;

/**

public class EncodingFilter implements Filter{
                   ///===================================================================================
public void init(FilterConfig config) throws ServletException {
    //No-op
}
    ///===================================================================================
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain       chain) 
                                                       throws IOException,     ServletException {
        request.setCharacterEncoding("UTF-8");
        response.setCharacterEncoding("UTF-8");
        chain.doFilter(request, response);
    }
    ///==================================================================================
    public void destroy() {
        //No-op
    }    
    ///===================================================================================
}
