vc 通达信行情接口-SpringBoot中怎样对外开放一个接口返回Json数据

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.vc 通达信行情接口,data;

import java.io.Serializable;

@vc 通达信行情接口,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 {

    @Autowired
    private ConfigProperties configProperties;

    @Resource
    private WmsReceiveOrderDetailsMapper wmsReceiveOrderDetailsMapper;

    @Resource
    private WmsReceiveOrderMapper wmsReceiveOrderMapper;

    @Resource
    private BusTrayMaterielMapper busTrayMaterielMapper;

    @Description('测试接口')
    @RequestMapping(value = '/getStr', method = RequestMethod.POST)//正式改成POST
    @ResponseBody
    public 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

这里修改

为了测试POST方式，这里使用Postman进行测试
