如果PostMethod提交的是中文字符,需要加上相应的编码格式:  post.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");  
如果GetMethod提交的参数有中文字符,需要先转换成utf-8格式:  URLEncoder.encode("中文", "utf-8"); 
测试代码如下:
package httpclient;

import java.io.IOException;
import java.net.URLEncoder;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;

public class HttpClientTest {

	public static void main(String[] args) throws Exception{
		String url = "/xx.jsp/xxxx";
		String host = "www.xxx.cn";
		String param = "city="+URLEncoder.encode("测试", "utf-8")+"&userID=";
		HttpClient httpClient = new HttpClient();
		httpClient.getHostConfiguration().setHost(host, 80, "http");

		HttpMethod method = getMethod(url, param);
		//HttpMethod method = postMethod(url);

		httpClient.executeMethod(method);

		String response = method.getResponseBodyAsString();
		//String response = new String(method.getResponseBodyAsString().getBytes("ISO-8859-1"));
		System.out.println(response);
	}

	private static HttpMethod getMethod(String url,String param) throws IOException{
		GetMethod get = new GetMethod(url+"?"+param);
		get.releaseConnection();
		return get;
	}

	private static HttpMethod postMethod(String url) throws IOException{
		PostMethod post = new PostMethod(url);
		post.setRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8"); 
		NameValuePair[] param = { new NameValuePair("city","测试"),
				new NameValuePair("userID","")} ;
    	        post.setRequestBody(param);
    	        post.releaseConnection();
		return post;
	}
}
