Spring框架中接收Http客户端的Post和Get请求

本文主要是介绍了在Spring框架中接收Http客户端所传输的参数以及请求

由于Spring框架可以与数据库mybatis以及Hibernate较好的集成，使用接收的数据更易储存到数据库中

同时能够通过HTTP请求从数据库中查询获取需要的信息

因为Http的请求和Web请求一样都是通过URL来访问，所以也将其放在Controller层

在方法结束后加入Return可以直接向Client端发送返回信息

以下是具体的实现代码：

package com.firstdata.opensystem.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.firstdata.opensystem.service.FileConfigService;
import com.firstdata.opensystem.service.FileReportService;
import com.firstdata.opensystem.vo.FileConfig;

import net.sf.json.JSONObject;

@Controller
@RequestMapping("/MsgReceive")
public class MsgReceiveAction {

private static Logger logger = Logger.getLogger(MsgReceiveAction.class);

@Resource
private FileReportService fileReportService;

@Resource
private FileConfigService fileConfigService;

@RequestMapping(value = "", method = RequestMethod.POST)
@ResponseBody
public String msgReceive(@RequestBody String Msg) {
System.out.println(Msg);
JSONObject obj = JSONObject.fromObject(Msg);
fileReportService.addNewFileReport(obj);
logger.info("Receive File Report request for " + obj.getString("fileCode"));
return "000";
}

与Post方法不同的是Get方法还是使用HttpServletRequest的方式获取到URL的参数
由于Get的请求方式是将参数放在URL/后面

@RequestMapping(value = "", method = RequestMethod.GET)
@ResponseBody
public String recordInquiry(HttpServletRequest request) {
String fileCode = request.getParameter("fileCode");
String bizDate = request.getParameter("bizDate");
boolean inquiryFlag = fileReportService.inquiryFileReport(fileCode, bizDate);
FileConfig fileConfig = fileConfigService.getFileConfigByFileCode(fileCode);
String respMsg = String.valueOf(inquiryFlag)+" = "+fileConfig;
logger.info("Inquire whether " + fileCode + " has existed. Result: " + respMsg);
return respMsg;
}

}
