Below is my code:

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);
    }
}

I want to keep the server running so that client can hit it for response. Please Suggest.

Answer 1

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.

Things to try out.

1. Execute "mvn dependency:tree" and check whether the tomcat dependencies exist and in "compile" scope
2. Change the spring boot starter version to 1.4.0.RELEASE.

Answer 2

It worked when I changed spring boot version as follows:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.RELEASE</version>
  </parent> 

Answer 3

Try adding server.port=someAvailablePortNumber in the application.properties file located in "resources" folder.

I was also facing same problem. tried a lot of changes suggested in pom.xml file but nothing worked for me. In my case the port 8080 wasn't available so it application wasn't able to start tomcat using default port(ie: 8080) causing it to shutdown immediately.

Changing the port number helped to start tomcat and application started working. Hope it helps :)

Answer 4

If we are not using a .RELEASE version of spring we need to add below repositories in our pom.xml file.

And we can use command "mvn spring-boot:run" to run our spring application from command line.

<!-- (you don't need this if you are using a .RELEASE version) -->
<repositories>
        <repository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/snapshot</url>
            <snapshots><enabled>true</enabled></snapshots>
        </repository>
        <repository>
            <id>spring-milestones</id>
            <url>http://repo.spring.io/milestone</url>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>spring-snapshots</id>
            <url>http://repo.spring.io/snapshot</url>
        </pluginRepository>
        <pluginRepository>
            <id>spring-milestones</id>
            <url>http://repo.spring.io/milestone</url>
        </pluginRepository>
    </pluginRepositories>

Answer 5

What solved it for me was updating the "parent" reference in the pom.xml.

this is my working pom.xml :

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>

<groupId>com.boot</groupId>
<artifactId>project-boot</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.1.RELEASE</version>
</parent>

<name>project-boot</name>
<url>http://maven.apache.org</url>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

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

Answer 6

In your main function "SpringApplication.run(Main.class, args.close());" should not be in close , it shuld be like "SpringApplication.run(Main.class, args);"

Example :

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

Answer 7

Check your log config, maybe you're trying to save logs into the folder, that can't be created.

<appender name="allFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>/var/log/app/all.log</file>
         ...
</appender>

Answer 8

i encountered the same problem, my os is win7, my ide is eclipse, after i changed spring boot version to 1.5.7.release, erverything is ok.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.7.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
</dependency>

i have tried spring boot 2.0.2.release, 1.5.13.release, 1.5.1.release, they all cant run on my win7 os using eclipse, but they can run my ubuntu16.04 using command line and mvn compile with the same code.

Answer 9

Clearing my local Maven repo solved this issue for me. Easiest way is to remove ~/.m2/repository

Answer 10

删除了spring-boot-starter-tomcat依赖项并且它有效。
