提问by stack man

I am trying to write a simple RESTful service using Spring Boot. However, there is an error message I am not able to solve. I have been researching and it looks like it is a conflict between SpringBoot versions, however I am not sure about how can I get rid of it.

我正在尝试使用 Spring Boot 编写一个简单的 RESTful 服务。但是，有一条我无法解决的错误消息。我一直在研究，看起来它是 SpringBoot 版本之间的冲突，但是我不确定如何摆脱它。

I have this SpringBootApp:

我有这个 SpringBootApp：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * REST Service application

@SpringBootApplication
public class Application {

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

Recommended Approach

推荐方法

Go to Spring boot Initialzrsite and select web stack as a dependency as shown in below .
As Spring Boot uses the concept of Opinionated dependencies and Bill of Materials, It will automatically pull the other dependencies and resolve your classNotFoundException issue. And in your case it misses out the Spring-core-4.2.4.RELEASE.jar dependency.

Execute the Maven Goal as clean install spring-boot:run -eand you can find your maven dependencies in your IDE and below given is a sample POM file.

  <?xml version="1.0" encoding="UTF-8"?>
 <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.example</groupId>
  <artifactId>demo</artifactId>
 <version>0.0.1-SNAPSHOT</version>
 <packaging>war</packaging>

     <name>demo</name>
    <description>Demo project for Spring Boot</description>

     <parent>
       <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
     <version>1.4.0.RELEASE</version>
     <relativePath/> <!-- lookup parent from repository -->
   </parent>

    <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
       <project.reporting.outputEncoding>UTF-       8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    </properties>

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

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

  <build>
    <finalName>demo</finalName>
       <plugins>
         <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
    </build>

转到Spring boot Initialzr站点并选择 web stack 作为依赖项，如下所示。
由于 Spring Boot 使用了Opinionated 依赖项和物料清单的概念，它会自动拉取其他依赖项并解决您的 classNotFoundException 问题。在您的情况下，它错过了 Spring-core-4.2.4.RELEASE.jar 依赖项。

以clean install spring-boot:run -e 的方式执行 Maven 目标，您可以在 IDE 中找到您的 Maven 依赖项，下面给出的是一个示例 POM 文件。

I had same problem with Spring boot 2.1.9.RELEASE

我对 Spring boot 2.1.9.RELEASE 有同样的问题

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.9.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

Added pom dependency eliminated this exception:

添加 pom 依赖项消除了此异常：

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <version>5.2.0.RELEASE</version>
    </dependency>

EDIT- better approach.

编辑- 更好的方法。

Also clean up of maven repository with spring dependencies resolved problem for me, there were not need to add spring-core 5.2.0.RELEASE in pom. Seems that when I had many versions of spring in repo some problem occurs. Also before again resolve dependencies dont forget clean project.

还清理了具有 spring 依赖项的 maven 存储库，为我解决了问题，不需要在 pom.xml 中添加 spring-core 5.2.0.RELEASE。似乎当我在 repo 中有许多版本的 spring 时会出现一些问题。同样在再次解决依赖项之前不要忘记清理项目。
