为什么我的春季启动应用程序总是在启动后立即关闭?

这是我的第一个Spring Boot代码。不幸的是，它总是关闭。我希望它能够持续运行，这样我的web客户端就可以从浏览器中获取一些数据。

package hello;
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;

@Controller
@EnableAutoConfiguration
public class SampleController {

    @RequestMapping("/")
    @ResponseBody
    String home() {
        return "Hello World!";
    }

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

请建议。

谢谢

注:构建。是Gradle的错。

dependencies {
    // tag::jetty[]
    compile("org.springframework.boot:spring-boot-starter-web") {
        **exclude module: "spring-boot-starter-tomcat"**
    }

一旦我去掉上面粗体的一行，一切都正常了。我的应用程序上下文现在是正确的。谢谢你戴夫

当前回答

我也有同样的问题，但当我切除

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

它又开始工作了。

其他回答

也许它不适合你的代码，但我发现如果你有这样的代码片段:

@SpringBootApplication
public class SpringBootApacheKafkaApplication {

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

然后只需删除close()方法。这解决了我的问题!也许我能帮上忙

这适用于spring boot 2.0.0

取代

  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
        </dependency>

with

<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>9.0.6</version>
    </dependency>

只是另一种可能性，

我更换了

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

与

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

一开始没有任何问题

以下是解决方法:

检查pom.xml文件中是否没有spring-boot-start -web依赖项。要获得正确的pom.xml文件，请使用这个链接start.spring.io

如果您有上述依赖关系，但仍然面临这个问题，则很可能存在您的嵌入式tomcat jar。要确认这一点，请在调试模式下运行maven build -

mvn spring-boot:run --debug

在我的情况下，我修复了这个问题如下:-

First I removed (apache) C:\Users\myuserId\.m2\repository\org\apache I added below dependencies in my pom.xml file <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> I have changed the default socket by adding below lines in resource file ..\yourprojectfolder\src\main\resourcesand\application.properties(I manually created this file) server.port=8099 spring.profiles.active=@spring.profiles.active@ for that I have added below block in my pom.xml under <build> section. <build> . . <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> </resource> </resources> . . </build>

最终的pom.xml文件是这样的

<?xml version="1.0" encoding="UTF-8"?>
