解决JSP或STRUTS中的中文乱码问题

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 static final String CHARSET = "gb2312";

public void destroy() {

}

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding(CHARSET);
chain.doFilter(request, response);
}

public void init(FilterConfig arg0) throws ServletException {

}
}

web.xml中配置

<filter-name>EncodingFilter</filter-name>

<filter-class>com.zzy.qq_fo.encoding.EncodingFilter</filter-class>
</filter>

- <filter-mapping>

<filter-name>EncodingFilter</filter-name>

<url-pattern>/*</url-pattern>
</filter-mapping>
