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

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
}
///===================================================================================
}
