I am trying to POST a JSON array to a spring-boot controller but nothing happens or even shows up in the logs

Question

ISSUE: I am trying to POST to an array to a controller but nothing seems to be happening, there is no info in the logs or on the terminal

I have a JSON array as follows

[
    {   
        "artifact_id": 10,
        "session_id":45,
        "user_id": "user99"
    }
]

I am trying to use this with a.saveAll() from my CRUD repo but nothing seems to happen it does not even seem to print my System.out.print("test"); message. My @Entity class is as follows

@Entity
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
@Table(name = "ESearch_results", schema = "public")
public class ESearchResponse {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "primary_key", nullable = false)
    int primary_key;

    @Column(name = "artifact_id")
    int artifact_id;

    @Column(name = "session_id")
    int session_id;

    @Column(name = "user_id")
    String user_id;
}

my controller is as follows

@RestController
public class EsearchTestController {
    @Autowired
    private EsearchResponseService EsearchResponseService;
    
    @CrossOrigin
    @PostMapping("/justATest")
    public String testController(@RequestBody List<ESearchResponse> ESearchResponseTypo){
        String result = "this test passed";

        // System.out.print("\u001B[35m"+EsearchResponseService.saveESearchResult(ESearchResponseTypo));
        System.out.print("\u001B[35m"+ESearchResponseTypo.size());
        EsearchResponseService.saveESearchResult(ESearchResponseTypo);
        return result;
    }
}

I have tried many things and I believe my root issue here is the way I am passing the JSON array in the request body.

Try add a @RequestMapping("/some_path") to your controller.

I used to getting the same problem, and it was the lack of @RequestMapping annotation in my case.

And be careful of your port settings in properties file:

server.port=8000
