在 Spring Boot 中未调用 Rest Controller 方法

Question

I am implementing rest webservice via a spring boot application.

application.properties

server.port=8082
server.contexPath=/services
logging.level.org.springframework.web = DEBUG
logging.level.com.myCompany= INFO
logging.file = ../logs/services.log

Application launcher class

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Controller

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class AccountRestController {

    private static final Logger logger = LoggerFactory.getLogger(AccountRestController.class);

    @RequestMapping(value="/account", method=RequestMethod.GET)
    public void createAccount(){
        logger.info("ACCOUNT METHOD CALLED");
    }
} 

I see Did not find handler method for [/services/account] message in the console when I fire http://localhost:8082/services/account URL in the browser as shown below

2018-02-06 08:30:42.868 DEBUG 7532 --- [http-nio-8082-exec-3] s.w.s.m.m.a.RequestMappingHandlerMapping : Looking up handler method for path /services/account

I dont see message - ACCOUNT METHOD CALLED in the console meaning controller method is not getting invoked.Can you please let me know why createAccount() method not getting called ?
Is controller class getting identified/scanned by Spring factory?
What is causing this error?

Answer 1

Please change server.contexPath to server.contextPath .

And try again, it should work as there's no extra config or code is there.

Answer 2

1. Can you help us to capture your project structure? AccountRestController should be in the same package (or in sub-package) of Application . Like this:
2. Did you check you log file? Does it has any log?

Answer 3

Your server.contexPath should be server.contextPath. You missed a T in contexPath.

Answer 4

there is no request mapping in your class level. After @RestController , There should be @RequestMapping("/services/*)

Answer 5

看起来您拼写了该属性，它应该是server.contex t路径，而不是您所用的server.contexPath（w / oa't'）。

Answer 6

Your controller should be in the same package or in any subpackage of your main SpringBootApplication file.

If you want to include controllers present in either some other package or in a higher level then you can specifically mention that using componentScan annotation.

As shown in the below reference image, my login controller is not present in the same or subpackage of StudentServicesApplication.java . Hence I have specifically mentioned the package name of the controller to be considered using componentScan
