Question

我正在使用Spring启动和hibernate构建应用程序，在添加存储库之后，我遇到了这样的错误：

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.2.7.RELEASE:run (default-cli) on project app: An exception occured while running. null: InvocationTargetException: Failed to read candidate component class: file [/home/scabbard/projects/app/app-back-end/target/classes/com/springapp/app/config/RepositoryConfig.class]; nested exception is java.lang.annotation.AnnotationFormatError: Invalid default: public abstract java.lang.Class org.springframework.data.jpa.repository.config.EnableJpaRepositories.repositoryBaseClass() -> [Help 1]

看起来问题出在EnableJpaRepositories上，但无法找出原因。

以下是其他文件：

存储库文件

package com.springapp.app.repository;

import com.springapp.app.entity.PressEntity;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface PressRepository extends JpaRepository<PressEntity, Long> {
}

配置文件

package com.springapp.app.config;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.orm.jpa.EntityScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@Configuration
@EnableJpaRepositories("com.springapp.app.repository")
@EnableAutoConfiguration
@EntityScan("com.springapp.app.entity")
public class RepositoryConfig {
}

的pom.xml

Answer 1

使用“spring-boot-starter-data-jpa”更改了hibernate依赖项和“spring-data-jpa”并添加了“application.properties”后，它解决了我的问题。
