问题描述
我正在尝试构建一个简单的SpringBoot应用程序。当我运行我的spring启动应用程序时,它在启动后立即关闭,下面是控制台日志:
I am trying to build a simple SpringBoot application. When I run my spring boot application it shutdown immediate after starting, below is the console log:

以下是我的代码:
SpringBootDemo1Application.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Configuration
@EnableAutoConfiguration
@ComponentScan
@Controller
public class SpringBootDemo1Application {
@ResponseBody
@RequestMapping("/")
public String entry(){
return "My spring boot application";
}
public static void main(String[] args) {
SpringApplication.run(SpringBootDemo1Application.class, args);
}
}

我想让服务器保持运行,以便客户端可以点击它以获得响应。
请建议。
I want to keep the server running so that client can hit it for response.Please Suggest.
推荐答案
我能想到的唯一可能的解释是tomcat嵌入式jar不包含在依赖性/罐。由于您已经定义了spring-boot-starter-web依赖项,因此它应该也可以传递性地提取嵌入式tomcat依赖项。但不知怎的,它被排除在外。
The only possible explanation i can think of is that tomcat embedded jar is not included in the dependencies/jar. Since you have already defined "spring-boot-starter-web" dependency, it should have transitively pulled the embedded tomcat dependencies as well. But somehow it is excluded.
要试试的东西。
- 执行 mvn dependency:tree并检查tomcat依赖项是否存在以及compile范围
- 将spring boot starter版本更改为1.4.0.RELEASE。
