Question

这是我的控制人：

package pizzainthecloud.pizzaplace.controller;

import com.heavyweightsoftware.exception.HeavyweightException;
import org.addycaddy.client.dto.ContactPointDto;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import pizzainthecloud.pizzaplace.service.AddressValidationService;

import java.util.Random;

@CrossOrigin
@RestController(value = "/address")
public class AddressController {
    public static final String          KEY_ADDRESS = "address";

    private static final Logger         log = LoggerFactory.getLogger(AddressController.class);

    @Autowired
    private AddressValidationService    addressValidationService;

    private Random                      random = new Random();
    private ContactPointDto[]           contactPointDtos = new ContactPointDto[] {
        getContactPoint1(),
        getContactPoint2(),
        getContactPoint3(),
        getContactPoint4(),
        getContactPoint5()
    };

    @RequestMapping(value = "/validate", method = RequestMethod.POST)
    @ResponseBody
    public ContactPointDto[] validate(@RequestParam(KEY_ADDRESS) ContactPointDto address) {

        ContactPointDto[] result;
//        try {
//            result = addressValidationService.validate(address);
//        } catch (HeavyweightException he) {
//            String msg = "Error validating address:" + address;
//            log.error(msg, he);
//            result = new ContactPointDto[0];
//        }

        if (random.nextBoolean()) {
            //sometimes return just one
            int idx = random.nextInt(contactPointDtos.length);
            result = new ContactPointDto[] {contactPointDtos[idx]};
        }
        else {
            result = contactPointDtos;
        }

        return result;
    }

    public static ContactPointDto getContactPoint1() {
        ContactPointDto result = new ContactPointDto();

        result.setStreet1("1 Testy Person Way");
        result.setCity("Testerville");
        result.setState("KY");
        result.setPostalCode("40419");

        return result;
    }

    public static ContactPointDto getContactPoint2() {
        ContactPointDto result = new ContactPointDto();

        result.setStreet1("2 Testy Person Way");
        result.setCity("Testerville");
        result.setState("KY");
        result.setPostalCode("40419");

        return result;
    }

    public static ContactPointDto getContactPoint3() {
        ContactPointDto result = new ContactPointDto();

        result.setStreet1("3 Testy Person Way");
        result.setCity("Testerville");
        result.setState("KY");
        result.setPostalCode("40419");

        return result;
    }

    public static ContactPointDto getContactPoint4() {
        ContactPointDto result = new ContactPointDto();

        result.setStreet1("4 Testy Person Way");
        result.setCity("Testerville");
        result.setState("KY");
        result.setPostalCode("40419");

        return result;
    }

    public static ContactPointDto getContactPoint5() {
        ContactPointDto result = new ContactPointDto();

        result.setStreet1("5 Testy Person Way");
        result.setCity("Testerville");
        result.setState("KY");
        result.setPostalCode("40419");

        return result;
    }
}

运行Spring Boot应用程序时，我得到：

因此，似乎不是在映射我的控制器。我包括了：

@SpringBootApplication
@EnableTransactionManagement
@ComponentScan(basePackageClasses = {Application.class, PizzaPlaceController.class} )
@EnableScheduling
public class Application {

在我的应用程序类中，PizzaPlaceController在工作，并且与AddressController在同一程序包中，并且发现PizzaPlaceController很好。

这里的答案没有帮助：RequestMappingHandlerMapping.getHandlerInternal:230 - Did not find handler method for

将AddressController添加到@ComponentScan列表中并没有任何改变。

Answer 1

您为路径指定了错误的值。使您的控制器是这样的。 @SpringBootApplication扫描当前包及其子包中的所有文件。如果您的控制器不在当前软件包中，则只需提供扫描路径即可。

     @RestController// value is the component name 
     @RequestMapping(value = "/blogs")// this value is the path
     public class BlogController {

       @Autowired
       private BlogService<BlogRequestDTO, BlogResponseDTO> service;

       @GetMapping
       public ResponseEntity<List<BlogResponseDTO>> getAllBlog() {
          return new ResponseEntity<>(service.getAll(), 
             HttpStatus.OK);
       }

       @GetMapping(value = "/{blogId}")
       public ResponseEntity<BlogResponseDTO> 
          getBlog(@PathVariable(required = true) String blogId) {
          BlogRequestDTO request = new BlogRequestDTO();
          request.setId(Long.valueOf(blogId));
          return new ResponseEntity<>(service.get(request), 
          HttpStatus.OK);
       }
    }

我们需要阅读@ RestController，@ RequestMapping的文档并检查value属性在两个注释中是否具有不同的功能。这里是一个有效的示例https://github.com/BALVIKASHSHARMA/SampleBlog

Answer 2

事实证明，问题出在@RequestMapping。我以为如果在RestController上放置“ / address”，然后在总路径为“ / address / method”的方法上进行“ validate”。

事实证明，映射是“ / validate”。我将请求方法更改为“ / address / validate”，并且工作正常。

感谢您的帮助。

Answer 3

从Application类中删除以下行。

@ComponentScan(basePackageClasses = {Application.class, PizzaPlaceController.class} )

它应该为您工作。

Spring不匹配我的请求到我的控制器
