servelet 实现Post接口访问

先上代码：

package com.jovtec.galaxy.mailbox;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.sf.json.JSONObject;

import com.jovtec.galaxy.object.SysObject;
import com.jovtec.galaxy.util.DateHelper;

public class MailboxAction extends HttpServlet {

	/**
	 *
	 */
	private static final long serialVersionUID = 1L;

	/**
	 * 覆盖Get方法
	 */
	@SuppressWarnings("unchecked")
	public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		response.setContentType("application/json");
		response.setCharacterEncoding("UTF-8");
		// 返回JSON数据
		JSONObject resultObject = new JSONObject();
		// 获取post提交的回复案件的信息
		String postResult = reqMailbox(request);
		//实现逻辑...
		response.getOutputStream().write(resultObject.toString().getBytes("UTF-8"));
	}

	/**
	 * 获取请求头内容
	 *
	 * @param request
	 * @return
	 * @throws IOException
	 */
	private String reqMailbox(HttpServletRequest request) throws IOException {
		// 读取请求内容
		BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream(), "UTF-8"));
		String line = null;
		StringBuilder sb = new StringBuilder();
		while ((line = br.readLine()) != null) {
			sb.append(line);
		}
		// 将资料解码
		return sb.toString();
	}

	/**
	 * 跳转到Get方法
	 */
	public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doGet(request, response);
	}

}

1.首先，先继承HttpServlet，获取post请求的参数。

2.需要在web.xml里面做相应的配置，配置如下：

<servlet>
<servlet-name>MailboxAction</servlet-name>
     <servlet-class>com.jovtec.galaxy.mailbox.MailboxAction</servlet-class>
</servlet>
<servlet-mapping>
     <servlet-name>MailboxAction</servlet-name>
      <url-pattern>/mailbox/MailboxAction</url-pattern>
</servlet-mapping>

访问接口的路径，就是项目路径+/mailbox/MailboxAction
