Question

问题是我的休息控制器没有被调用。

@SpringBootApplication(scanBasePackages = { "com.company.base" })
public class Application {

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

@RestController
@RequestMapping("/data")
public class DataController {

    private static final Logger LOGGER = LogManager.getLogger(MethodHandles.lookup().lookupClass());

    @Autowired
    private SusbscriberRepository susbscriberRepository;

    @RequestMapping(value = "/subscribers", method = RequestMethod.GET)
    public HttpEntity<SubscriberResource> findAll() {
     ...
    }

    @RequestMapping(value = "/subscriber/{id}", method = RequestMethod.GET)
    public ResponseEntity<SubscriberResource> findSubscriber(@PathVariable(value = "id") Long id) {
      ...
    }
}

在Springboot开始日志中，映射了这些URL。

我确定我错过了一些东西，但我不知道是什么。

即使是春天的例子也不起作用：gs-actuator-service-master。

Answer 1

有三件事可能有问题

spring-boot-starter-tomcat＆amp;缺少spring-boot-starter-web lib。
由于您已定义com.company.base。

scanBasePackages

Spring boot应用程序必须与SpringBootServletInitializer一起运行。只有在以Java应用程序运行时才需要这种情况，如果从mvn命令运行则不需要。

请添加图书馆＆amp;更新您的Application.java，然后重试。

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

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

}

Answer 2

如果控制器位于启动应用程序包或子包下，请删除scanBasePackages = {“com.company.base”}。或者在组件扫描中包括主类的包。

Answer 3

我遇到了类似的问题。我添加了 spring-mvc 依赖项。

compile "org.springframework:spring-webmvc:5.1.3.RELEASE"

默认情况下，主类应位于根包中。我将主类放入另一个包中，因此必须进行组件扫描并添加其他可用组件。

package root.package1

@SpringBootApplication(scanBasePackages = {"root"})

公共类WebAppMain {

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

Answer 4

将控制器类移动到应用程序类的子包中。

like 
    com.company.base for Application class
    com.company.base.controller for DataController class

然后，弹簧靴将自动扫描控制器。

没有调用springboot restcontroller
