Question

我是spring-boot的新手，并创建了一个具有一个控制器方法的虚拟应用程序。

应用程序的包装类型在pom文件中以jar形式提及。部署后，日志中没有错误。

但是在成功构建和部署后，当我尝试从浏览器访问本地主机时，仍然出现404错误。

下面是我已经尝试解决的问题：

1）在同一包中包含我的主类和控制器类。 2）我的主类放在根包中，控制器放在子包中。 3）在类和方法上定义@RestController。 4）在主类中扩展SpringBootServletInitializer

package com.test.controller;

    @SpringBootApplication
    public class TestApplication  {

        public static void main(String[] args) {

            SpringApplication.run(TestApplication.class, args);
        }

    }


 **Controller class**




     package com.test.controller;

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

        @RestController
        public class TestController {

            public final Logger logger = LoggerFactory.getLogger(TestController.class);

            @RequestMapping(value = "/test", method = RequestMethod.GET)
            public String test() {
                logger.info("This is a test message to check if logback is working");
                return "Hello World";
            }
        }

因此，根据结果，我应该在网页上收到Hello World消息，但是却收到404错误。

本地主机上的Spring Boot应用程序出现404错误，日志中没有异常
