Question

编译spring项目时，出现以下错误。

创建在类路径资源[org / springframework / boot / autoconfigure / orm / jpa / HibernateJpaAutoConfiguration.class]中定义的名称为'entityManagerFactory'的bean时出错：调用init方法失败

我正在使用STS Eclipse和MySql数据库

我的连接字符串Application.Properties是

spring.datasource.url=jdbc:mysql://localhost:3306/stgdb

spring.datasource.username=root

spring.datasource.password=root

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.jpa.hibernate.ddl-auto=update

Answer 1

我将从添加以下依赖关系开始：<dependency>&nbsp; &nbsp; <groupId>org.hibernate</groupId>&nbsp; &nbsp; <artifactId>hibernate-core</artifactId>&nbsp; &nbsp; <version>4.1.4.Final</version></dependency>和<dependency>&nbsp; &nbsp; <groupId>org.hibernate</groupId>&nbsp; &nbsp; <artifactId>hibernate-entitymanager</artifactId>&nbsp; &nbsp; <version>5.2.3.Final</version></dependency>更新 ：或只需添加以下依赖项。<dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>javax.xml.bind</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>jaxb-api</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <version>2.3.0</version></dependency>

Answer 2

使用Java 9的人包括这种依赖关系：<dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>javax.xml.bind</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>jaxb-api</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <version>2.3.0</version></dependency>

Answer 3

我也面临同样的问题。我正在使用Java9，并在pom文件中遵循以下依赖关系：<dependencies>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>spring-boot-starter-data-jpa</artifactId>&nbsp; &nbsp; </dependency>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>spring-boot-starter-jdbc</artifactId>&nbsp; &nbsp; </dependency>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>spring-boot-starter-web</artifactId>&nbsp; &nbsp; </dependency>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>com.h2database</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>h2</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <scope>runtime</scope>&nbsp; &nbsp; </dependency>&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>spring-boot-starter-test</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <scope>test</scope>&nbsp; &nbsp; </dependency></dependencies>在pom中添加以下依赖项后，此问题已解决：&nbsp; &nbsp; <dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>javax.xml.bind</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>jaxb-api</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <version>2.3.0</version>&nbsp; &nbsp; </dependency>
