场景

在SpringBoot中开放一个接口，使C#程序中能访问接口并接受返回的数据、

实现

封装一个Json类

import lombok.Data;import java.io.Serializable;@Data public class Json implements Serializable {//默认未失败状态private static Json instance;private String msg = "接口访问失败";private String title = "失败提示";private boolean status = false;private int code = 300;private Object data = null;public synchronized static Json getInst() {if(instance==null){instance = new Json();}return instance;}public Json() {super();}public Json success(Object data){this.title = "成功提示";this.msg = "接口访问成功";this.status = true;this.code = 200;this.data = data;return this;}public Json success(){this.title = "成功提示";this.msg = "接口访问成功";this.status = true;this.code = 200;this.data = null;return this;}public Json fail(Object data){this.title = "失败提示";this.msg = "接口访问失败";this.status = false;this.code = 300;this.data = data;return this;}public Json fail(){this.title = "失败提示";this.msg = "接口访问失败";this.status = false;this.code = 300;this.data = null;return this;} }

在SpringBoot项目中的Controller中新建Controller

@Controller @RequestMapping("/wmsCleanWorkShop") @EnableConfigurationProperties(ConfigProperties.class) public class WmsCleanWorkShopController {@Autowiredprivate ConfigProperties configProperties;@Resourceprivate WmsReceiveOrderDetailsMapper wmsReceiveOrderDetailsMapper;@Resourceprivate WmsReceiveOrderMapper wmsReceiveOrderMapper;@Resourceprivate BusTrayMaterielMapper busTrayMaterielMapper;@Description("测试接口")@RequestMapping(value = "/getStr", method = RequestMethod.POST)//正式改成POST@ResponseBodypublic Json getStr(String barCode) {try{//String message = "1";if( message.substring(1,message.length()-1).equals("1")){return Json.getInst().success(finalBarCode);}else{return Json.getInst().fail("失败：调用接口失败");}}catch (Exception e){return Json.getInst().fail("生成失败:出现异常"+e.toString());}} }

效果

直接使用浏览器访问是get方式，需要将

 @RequestMapping(value = "/getStr", method = RequestMethod.GET)//正式改成POST

这里修改

为了测试POST方式，这里使用Postman进行测试

可以看到后台能接收到数据，然后进行相应的逻辑处理即可，这里不做处理使其返回失败。
