Tomcat 提交时的编码问题

一般 Tomcat 默认编码都不是UTF8 所以只有先手动设置 server.xml (Connector加个属性URIEncoding=”utf-8″)

或者加入如下过滤器，才能得到提交文本的正确编码

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 {
	private String charset=“UTF-8”;
	public void destroy() {
		// TODO Auto-generated method stub

	}

	@SuppressWarnings("unchecked")
	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException {
		// TODO Auto-generated method stub
		request.setCharacterEncoding(charset);

		chain.doFilter(request, response);
	}

	public void init(FilterConfig arg0) throws ServletException {
		// TODO Auto-generated method stub
		if(arg0.getInitParameter("charset")!=null)charset=arg0.getInitParameter("charset");
	}

}
