错误：无法在SpringBoot应用程序中找到或加载主类

上官凯歌
2023-03-14

我目前正在学习springboot。通过选择spring starter project，我在STS中创建了一个项目。spring boot版本2.2.2和已导入JPA、H2和RestRepository。

下面是我的领域类，

package com.jignesh.org.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity

public class Alien {

    @Id
    @GeneratedValue
    private int aid;
    private String name;
    private String tech;....

应用属性

spring.h2.console.enabled=true
spring.datasource.platform=h2
spring.datasource.url=jdbc:h2:mem:jignesh

存储库类

import com.jignesh.org.model.Alien;

@RepositoryRestResource(collectionResourceRel="aliens",path="aliens")
public interface AlienRepo extends JpaRepository<Alien, Integer>{

}

在波姆。xml显示了下面提到的错误。不确定，因为这一点，我得到了错误，但我没有在pom的任何变化。xml

Archive for required library: 'byte-buddy-1.10.4.jar' in project 'Spring Boot Build Path Problem

在运行项目时，我得到了以下错误，不知道为什么整个项目是从“https://start.spring.io”生成的

Error: Could not find or load main class com.jignesh.org.webapp.SpringBootTuto16SpringDataRestApplication

主要类：

package com.jignesh.org.webapp;

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

@SpringBootApplication
public class SpringBootTuto16SpringDataRestApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootTuto16SpringDataRestApplication.class, args);
    }

}

您好，我尝试过将主类保留在生成默认包的外部包中，但问题仍然是一样的。然后我删除了byte-buddy-1.10.4。IDE问题窗口中的jar问题，然后我得到了不同的错误。我正在尝试不同的解决方案，但仍然无法解决它。请在post中查找错误日志。
