Spring Controller给出了404状态错误

所以我试图用Spring注释在Spring Tool Suite中编写一个基本的Rest Controller，在那里我点击了 endpoints “/ health”，并在点击 endpoints “Kafka Streaming App Health ”时收到以下消息 .

我收到的唯一错误是404状态错误，当我检查浏览器并且我已经尝试记录请求帮助 . 我认为问题可能是我如何在Spring中的Main Application类中调用Controller .

Main Application Class

package com.eds.kafka.streaming.app;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.autoconfigure.domain.EntityScan;
    import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
    import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
    import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.Configuration;
    //import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

    //@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, DataSourceTransactionManagerAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
    //@Configuration

    //@EntityScan(basePackages = {"com.eds.kafka.streaming.model"})
    //@ComponentScan(basePackages = { "com.eds.kafka.streaming.service", "com.eds.kafka.streaming.util",  "com.eds.kafka.streaming.config", "com.eds.kafka.streaming.controller"}) //"com.tmobile.eds.infosec.volt.encr",
    @ComponentScan(basePackages = {"com.eds.kafka.streaming"})
    @SpringBootApplication
    public class KafkaStreamingAppContainerApplication extends SpringBootServletInitializer {


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


        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            return builder.sources(KafkaStreamingAppContainerApplication.class);
        }
    }

Controller Class

package com.eds.kafka.streaming.controller;

    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.PropertySource;
    import org.springframework.http.HttpStatus;
    import org.springframework.http.ResponseEntity;
    import org.springframework.stereotype.Component;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.bind.annotation.RestController;


    @EnableAutoConfiguration
    @PropertySource("classpath:application-${spring.profiles.active}.properties")
    @RestController
    public class MainController {

        @RequestMapping(method = RequestMethod.GET, value = "/health", produces = "application/json")
        @ResponseBody 
        public ResponseEntity home() {
            System.out.println("Controller being configured!");
            return new ResponseEntity("Kafka Streaming App is Healthy", HttpStatus.OK);
        }


    }

如果您有任何建议，请告诉我，如果需要，我可以提供项目的压缩版本，如果需要，请给我留言 .
