Spring Boot GetMapping 404

Question

I'm studying Java Spring Boot. But my get request always return 404, but my post request could succeed. I'm so confused. Here is my Java code:

@Controller
public class LexicalAnalysisController {


    @CrossOrigin 
    @GetMapping(value = "api/LexicalAnalysis/test")
    public String test(){
        return "111";
    }


}

Here is my javaScript code:

scan(){
        this.$axios
          .get('/LexicalAnalysis/test')
          .then((response) => {
            console.log(reponse.data);
          })
          
          .catch(failResponse =>{

          })
        
      }

Here is my error information:

So what's wrong? Thank you very much!

Answer 1

either change @controller to @RestController or add @ResponseBody below @controller . ResponseBody annotation binds a method return value to the web response body therefore it is required.

Answer 2

You should replace @Controller with @RestController .
