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;@Resourceprivate 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;    }}
