I have 2 GET handler methods
@RestController
public class TestController {
...
@GetMapping(name = "/test")
public Test testMethod() {
return testService.getTest();
}
@GetMapping(name = "/test/{count}")
public List<Test> getTestList2(@PathVariable(name = "count") Integer count) {
return testService.getTestList(count);
}
}
And I get error:
Caused by: java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'testController' method
public java.util.List<models.Test> TestController.getTestList2(java.lang.Integer)
to {[],methods=[GET]}: There is already 'testController' bean method
If I comment one method all work fine
What you are doing mistake is you are telling @GetMapping
name rather that its value, It might feel both of them works the same way but it has tiny differences.
RequestMapping.name : Assign a name to this mapping.
and
RequestMapping.value : The primary mapping expressed by this annotation. Supported at the type level as well as at the method level! When used at the type level, all method-level mappings inherit this primary mapping, narrowing it for a specific handler method .
@RestController
public class TestController {
@GetMapping(value = "/test")
public String testMethod() {
return "Hello from test";
}
@GetMapping(value = "/test/{count}")
public String testMethod(@PathVariable(value = "count") Integer count) {
return "Hello from Parameterized Test. Count: " + count;
}
}
Hence you are specifying the path or route of your Controller it all always preferable to specify the value
