尽管调用了方法，为什么AbstractMvcEndpoint的子类仍返回404？

Question

Putting a breakpoint inside my endpoint method, i see it is called and it returns without any error. But when it reaches the browser, it says it was a 404 error.

@Configuration
@ManagementContextConfiguration
@CacheController
public class TestController extends AbstractMvcEndpoint
{
    public TestController()
    {
        super( "/testendpoint", false, true );
    }

    @GetMapping( value = "/testendpoint", produces = MediaType.APPLICATION_JSON_UTF8_VALUE )
    public String getSomething(HttpServletRequest request) throws Exception
    {
        return "hello";
    }
}

What could be causing this?

Answer 1

In method getSomething(...) has return "hello"; Therefore, it will return a normal view ( Web page view ).

Because you want return JSON object, the outcome of the below method

@GetMapping( value = "/testendpoint", produces = MediaType.APPLICATION_JSON_UTF8_VALUE )
public String getSomething(HttpServletRequest request) throws Exception
{
    return "hello";
}

should be a JSON object .

For testing REST end-point, it should be use command curl (on Linux). If you use web browser, you can use JSON mark-up plug-in (For example: JSONView ).

You can do something likes this with sample source code .
