也可能提示:
java.lang.SecurityException: class “javax.persistence.ValidationMode“‘s signer information does not match signer information of other classes in the same package

B: 环境
jdk= 1.8.0_121-b13
tomcat= Apache Tomcat/8.5.32
spring framework= 5.0.7.RELEASE
jpa= 2.2.0
jpa.dialect= eclipselink 2.7.1

都是按spring framework编译环境定义的库版本:build.gradle

C: 原因分析
一开始我依赖的是eclipselink.jar，这是一个完整包，里面包含部分javax.persistence-2.2.0.jar代码

        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>eclipselink</artifactId>
            <version>2.7.1</version>
        </dependency>

同时它还需要依赖javax.persistence-2.2.0.jar, 这会导致两个jar中同时有：
javax.persistence.ValidationMode 和 javax.persistence.SharedCacheMode，…

D: 解决方法
在实体项目中(项目作了拆分,实体一个项目，接口一个项目，接口实现一个项目)，只依赖：

        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>javax.persistence</artifactId>
            <version>2.2.0</version>
        </dependency>

接口实现项目中依赖的eclipselink改用：

        <dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>org.eclipse.persistence.jpa</artifactId>
            <version>2.7.1</version>
        </dependency>

这时jar由一个（eclipselink.jar）变成了5个jar,分别如下:
org.eclipse.persistence.core-2.7.1.jar
org.eclipse.persistence.jpa.jpql-2.7.1.jar
org.eclipse.persistence.antlr-2.7.1.jar
org.eclipse.persistence.asm-2.7.1.jar
org.eclipse.persistence.jpa-2.7.1.jar
