没有找到处理程序方法

Question

我正在尝试调用rest端点，但在调用它时获取此信息，导致UI中出现404错误

self.master.after_idle

同一个包中有2个控制器类，具有不同的端点

2016-08-07 13:43:42.611 DEBUG 27834 --- [           main] s.w.s.m.m.a.RequestMappingHandlerMapping : Looking up handler method for path /api/v1/operations

2016-08-07 13:43:42.617 DEBUG 27834 --- [           main] o.s.w.s.handler.SimpleUrlHandlerMapping  : Mapping [/api/v1/operations] to HandlerExecutionChain with handler [ResourceHttpRequestHandler [locations=[ServletContext resource [/], class path resource [META-INF/resources/], class path resource [resources/], class path resource [static/], class path resource [public/]], resolvers=[org.springframework.web.servlet.resource.PathResourceResolver@39ead1b7]]] and 1 interceptor

我在同一个包中有另一个类：

@RestController
public class OperationRetrievalController {

    @Autowired
    OperationRetrievalManager operationRetrievalManager;

    private static Logger logger = Logger.getLogger(OperationRetrievalController.class);

    @RequestMapping("/api/v1/operations")
    public ResponseEntity<List<OperationView>> requestUserOperations() {
        String ssoId = "xxxxxx";
        logger.info("Inside request operationRetrivel Manager +++++++++>>>>>>>>");
        return new ResponseEntity<List<OperationView>>(operationRetrievalManager.retrieveOperations(ssoId), HttpStatus.OK);
    }


}

这是Spring启动应用程序类：

@RestController
public class ComponentRetrievalController {

    @Autowired
    ComponentRetrievalManager componentRetrievalManager;

    @RequestMapping(value = "api/v1/component/{sso_id}" , method=RequestMethod.GET)
    public ResponseEntity<List<Component>> requestUserComponent(@PathVariable("sso_id") String ssoId) {

        return new ResponseEntity<List<Component>>(componentRetrievalManager.retrieveComponents(ssoId), HttpStatus.OK);
    }


}

这是我的包的结构

当我删除Application.java中的所有注释并只保留@SpringBootApplication时，它会出现以下错误：

@SpringBootApplication
@EnableAutoConfiguration
@EnableJpaRepositories(basePackages="com.ge.power.bis.repositories")
@ComponentScan(basePackages="com.ge.power.bis.managers")
public class Application {

    private static Logger logger = Logger.getLogger(Application.class);


    public static void main(String[] args) {


        SpringApplication springApplication = new SpringApplication(Application.class);

        ApplicationContext ctx = springApplication.run(args);

        logger.info("Let's inspect the beans provided by Spring Boot:");
        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for (String beanName : beanNames)
        {
            logger.info(beanName);
        }       
    }
}

Answer 1

其中一个Impl类

缺少@Service

Answer 2

您需要将服务类标记为“ 可以制造bean ”，这样Spring的组件扫描才能制造bean和注入值。

这可以通过@Component注释来完成。如@sromit的答案中所述，添加@Service注释也将起作用，因为它已经继承了@Component。 @Repository和@Controller也继承了@Component注释。
