本文介绍了如何在Spring MVC服务器端利用@RequestBody注解接收HTTP POST请求中的数据，并将其自动转换为Java Bean。客户端部分，详细讲解了如何使用Apache HttpClient库来构造并发送包含Bean数据的POST请求。

服务器端为spring mvc，使用@RequestBody自动接收请求数据并转换为bean。

public class Wrapper {
	
	public VOBean data;

	public VOBean getData() {
		return data;
	}

	public void setData(VOBean data) {
		this.data = data;
	}
	

}

客户端使用apache的httpclient。

 
import java.io.IOException;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.StringRequestEntity;

public class PostClient {
	public static void main(String[] args) throws IOException {

		String url = "http://xxxx";
		HttpClient client = new HttpClient();
		PostMethod method = new PostMethod(url);
		method.setRequestHeader("Context-Type", "application/json; charset=utf-8");
		method.setRequestHeader("Accept", "application/json; charset=utf-8");

		VoBean avo= new VoBean();// set bean params
		net.sf.json.JSONObject jo = net.sf.json.JSONObject.fromObject(avo);
		String avoJson = "{\"data\":"+jo.toString()+"}";
		method.setRequestEntity(new StringRequestEntity(avoJson, "application/json", "utf-8"));
		try {
			client.executeMethod(method);
			String resp = "";
			if (method.getStatusCode() == HttpStatus.SC_OK)
				resp = method.getResponseBodyAsString();

			System.out.println(resp);
		} finally {
			method.releaseConnection();
		}

	}
}
