由于缺少bean，Webserver无法启动

我正在尝试启动一个简单的spring应用程序

我在这里有main.java文件：

package main; import javafx.application.Application; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.annotation.ComponentScan; @ComponentScan @EnableAutoConfiguration public class Main { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } 

这是我的libs：

这是pom.xml：

   4.0.0 blog blog 1.0-SNAPSHOT   org.springframework spring-web 4.0.0.RELEASE   org.springframework.boot spring-boot-autoconfigure 1.0.0.BUILD-SNAPSHOT   org.springframework.boot spring-boot 1.0.0.BUILD-SNAPSHOT    

最后错误就是这个：

据我所知，我错过了一个豆子？ 然而，看起来我确实有jar春豆。

Answer 1

Spring启动尝试启动Web服务器，但没有在类路径中找到任何内容。 尝试添加此依赖项

   org.springframework.boot spring-boot-starter-web I Dont know  

---

顺便说一句，你看起来不像典型的春季靴子！ 将其与http://projects.spring.io/spring-boot/docs/README.html进行比较

Answer 2

你需要添加注释：

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

Answer 3

我现在遇到了同样的错误，我通过在build.gradle文件中包含相同版本的Spring包解决了这个问题：

 buildscript { ext { springBootVersion = '1.1.6.RELEASE' } compile 'org.springframework.boot:spring-boot-starter-web' compile 'org.springframework.boot:spring-boot-starter-tomcat' compile 'org.springframework.boot:spring-boot-starter-security' compile 'org.springframework.boot:spring-boot-starter-actuator' compile 'org.springframework.boot:spring-boot-starter-aop' compile 'org.springframework.boot:spring-boot-starter-data-mongodb' 

例如，如果您更改了其中一个软件包并添加了版本号以覆盖静态值1.1.6.RELEASE，则会显示错误：

 buildscript { ext { springBootVersion = '1.1.6.RELEASE' } compile 'org.springframework.boot:spring-boot-starter-web' compile 'org.springframework.boot:spring-boot-starter-tomcat' compile 'org.springframework.boot:spring-boot-starter-security' compile 'org.springframework.boot:spring-boot-starter-actuator' compile 'org.springframework.boot:spring-boot-starter-aop' compile 'org.springframework.boot:spring-boot-starter-data-mongodb:1.2.5.RELEASE' 

Answer 4

根据版本的不同，有所不同。

org.springframework – >请更正为更高版本。 🙂

  org.springframework.boot spring-boot-starter-parent 1.2.3.RELEASE    org.springframework.boot spring-boot-starter-web   org.springframework spring-core 4.1.5.RELEASE   

例如，一个org.springframework.boot 1.2.3.RELEASE，错误始终是org.springframework 4.1.4.RELEASE下面的版本。

在超过org.springframework 4.1.5.RELEASE的情况下，我没有错误地工作。

我可能迟到了派对，但我可能只是为了寻找解决方案而节省了几个小时的痛苦。我在设置spring-boot项目时遇到了同样的问题。

我在build.gradle中有这个

 compile group: 'org.springframework.boot', name: 'spring-boot-starter- web', version: '1.5.9.RELEASE' //compile group: 'org.springframework', name: 'spring-context', version: '5.0.2.RELEASE'// <--- Source of my problems compile group: 'org.springframework.security.oauth', name: 'spring- security-oauth2', version: '2.2.1.RELEASE' compile group: 'com.fasterxml.jackson.datatype', name: 'jackson- datatype-jsr310', version: '2.9.3' testCompile group: 'com.h2database', name: 'h2', version: '1.4.196' compile group: 'mysql', name: 'mysql-connector-java', version: '6.0.6' compile group: 'org.hibernate', name: 'hibernate-core', version: '5.2.12.Final' compile group: 'commons-io', name: 'commons-io', version: '2.6' compile group: 'com.google.guava', name: 'guava', version: '23.6-jre' compile group: 'org.springframework.boot', name: 'spring-boot-starter- data-jpa', version: '1.5.9.RELEASE' testCompile group: 'junit', name: 'junit', version: '4.12' testCompile group: 'org.springframework.boot', name: 'spring-boot- starter-test', version: '1.5.9.RELEASE' 

这是一个spring-boot项目，所以它会为你做很多配置

也就是说，如果它是一个弹簧项目，你不需要一些你必须要放的依赖项。 引导启动程序依赖性就足够了。
