java - 无法执行目标 org.springframework.boot :spring-boot-maven-plugin:1. 5.8.RELEASE:run

我的主课:

    package com.db.databaseproject;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

  @SpringBootApplication
public class DataBaseProjectApplication {

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

ServletInitializer 类:

package com.db.databaseproject;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DataBaseProjectApplication.class);
    }

}

我通过 InteliJ 的 Spring 初始化器创建了这个类和 POM。我尝试通过命令“mvn spring-boot:run”运行我的应用程序。我有所有的依赖项，我用 spring 引用检查了我的代码我不明白这一点。

编辑:我的 POM 现在看起来像

现在我得到:在当前项目和插件组 [org.apache.maven.插件，org.codehaus.mojo] 可从存储库 [local (C:\Users\Pawel.m2\repository), central (https://repo.maven.apache.org/maven2)] -> [帮助1]

REFRESH:伙计们，它仍然无法正常工作，有什么可以帮助的吗？

Answer 1

您必须找出这两个类在哪些 JAR 中:org.springframework.util.ObjectUtils 和 org.springframework.validation.DataBinder。这两个 JAR 的版本不匹配。

我的预感是要么

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.0.1.RELEASE</version>
    </dependency>

或

    <dependency>
        <groupId>org.springframework.shell</groupId>
        <artifactId>spring-shell-starter</artifactId>
        <version>2.0.0.M2</version>
    </dependency>

引入不同版本的 Spring。使用 mvn dependency:tree 查看所有依赖项并检查重复项，并确保所有 Spring 依赖项具有相同的版本。
