場景

在SpringBoot中開放一個接口，使C#程序中能訪問接口并接受返回的數(shù)據(jù)、

實(shí)現(xiàn)

封裝一個Json類

import lombok.Data;import java.io.Serializable;@Data public class Json implements Serializable {//默認(rèn)未失敗狀態(tài)private static Json instance;private String msg = "接口訪問失敗";private String title = "失敗提示";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 = "接口訪問成功";this.status = true;this.code = 200;this.data = data;return this;}public Json success(){this.title = "成功提示";this.msg = "接口訪問成功";this.status = true;this.code = 200;this.data = null;return this;}public Json fail(Object data){this.title = "失敗提示";this.msg = "接口訪問失敗";this.status = false;this.code = 300;this.data = data;return this;}public Json fail(){this.title = "失敗提示";this.msg = "接口訪問失敗";this.status = false;this.code = 300;this.data = null;return this;} }

在SpringBoot項(xiàng)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("測試接口")@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("失敗：調(diào)用接口失敗");}}catch (Exception e){return Json.getInst().fail("生成失敗:出現(xiàn)異常"+e.toString());}} }

效果

直接使用瀏覽器訪問是get方式，需要將

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

這里修改

為了測試POST方式，這里使用Postman進(jìn)行測試

可以看到后臺能接收到數(shù)據(jù)，然后進(jìn)行相應(yīng)的邏輯處理即可，這里不做處理使其返回失敗。

總結(jié)
