问题:
I am creating an API with Spring Boot so wish to disable the /error mapping.
I have set the following props in application.properties:
server.error.whitelabel.enabled=false spring.mvc.throw-exception-if-no-handler-found=true spring.resources.add-mappings=false
However when I hit /error I get:
HTTP/1.1 500 Internal Server Error Server: Apache-Coyote/1.1 Content-Type: application/json;charset=UTF-8 Transfer-Encoding: chunked Date: Wed, 03 Aug 2016 15:15:31 GMT Connection: close {"timestamp":1470237331487,"status":999,"error":"None","message":"No message available"}
Required Result
HTTP/1.1 404 Internal Server Error Server: Apache-Coyote/1.1

You can disable the ErrorMvcAutoConfiguration :
@SpringBootApplication @EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class}) public class SpringBootLauncher {
Or through Spring Boot's application.yml/properties:
spring.autoconfigure.exclude: org.springframework.boot.autoconfigure.web.ErrorMvcAutoConfiguration
If this is not an option for you, you may also extend Spring's ErrorController with your own implementation:
@RestController public class MyErrorController implements ErrorController { private static final String ERROR_MAPPING = "/error"; @RequestMapping(value = ERROR_MAPPING) public ResponseEntity<String> error() { return new ResponseEntity<String>(HttpStatus.NOT_FOUND); } @Override public String getErrorPath() { return ERROR_MAPPING; }

In my case the problem was with web resources referenced in the header of the login page. Specifically, css was referenced in the header, but did not actually exist in the project.
What might also be helpful, in my WebSecurityConfigurerAdapter implementation I commented out the body of configure(WebSecurity web) first, then on trying to login, instead of displaying the above error json my browser's address bar would display the url to the resource causing the problem.
