在Spring boot整合JPA的时候,在网上查询添加的依赖

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

正常导入之后出现以下错误

 

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode; but it does not exist. Its class, javax.persistence.spi.PersistenceUnitInfo, is available from the following locations:

    jar:file:/D:/javaenvironment/apache-maven-3.6.0/repository/javax/persistence/persistence-api/1.0/persistence-api-1.0.jar!/javax/persistence/spi/PersistenceUnitInfo.class
    jar:file:/D:/javaenvironment/apache-maven-3.6.0/repository/javax/persistence/javax.persistence-api/2.2/javax.persistence-api-2.2.jar!/javax/persistence/spi/PersistenceUnitInfo.class

It was loaded from the following location:

    file:/D:/javaenvironment/apache-maven-3.6.0/repository/javax/persistence/persistence-api/1.0/persistence-api-1.0.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.persistence.spi.PersistenceUnitInfo


Process finished with exit code 0

 

 将依赖改为

 <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-jpa</artifactId>
            <version>2.1.5.RELEASE</version>
        </dependency>

正常解决!

或者:

 <!-- jpa-->

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
            <groupId>javax.persistence</groupId>
            <artifactId>javax.persistence-api</artifactId>
            <version>2.2</version>
        </dependency>
        <dependency>
            <groupId>javax.persistence</groupId>
            <artifactId>persistence-api</artifactId>
            <version>1.0</version>
        </dependency>

血泪教训,望参考。
