Question

我是春季靴子的新手，我的问题很简单，但是我找不到问题所在。

我有一个基本的@GetMapping和@DeleteMapping

@RestController
    public class MyController
    {
       private MyServiceImpl myService;

       @Autowired
       public MyController(MyServiceImpl myService)
       {
          this.myService = myService;
       }

       @GetMapping("/test")
       public List<Scan>  getTestData(@RequestParam(value = "test_id", required = true) String test_id) {
          return myService.findByTestId( test_id );
       }

      @DeleteMapping("/test")
       public int deleteData(@RequestParam(value = "test_id", required = true) String test_id){
          return myService.deleteTest( test_id );
       }

 @DeleteMapping("/test2")
   public String deleteArticle() {
      return "Test";
   }

    }

我正在与Postman进行测试，Get请求正在工作，但删除请求却没有。即使当我调试spring boot应用程序时。 GetMapping被调用，而删除不是“反应” /被调用

也许信息不够，但是我什至测试了 @DeleteMapping（“ / test2”）没有做任何事情，我的意思是，我没有任何反应，在Postman中它保持“正在加载。” 。”

有什么建议吗？

如SPR-16874中所述，在SPR注释中：

它当前不支持DELETE。这将是一个微不足道的变化使。建议一种解决方法：

@DeleteMapping(value = "/greeting")
public Greeting handle(@RequestBody MultiValueMap<String, String> params) {
    return new Greeting(counter.incrementAndGet(),
                        String.format(template, params));
}

您会看到issue已在spring boot跟踪器中打开。

无法识别@DeleteMapping
