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: 環境

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編譯環境定義的庫版本:build.gradle

C: 原因分析

一開始我依賴的是eclipselink.jar，這是一個完整包，裡面包含部分javax.persistence-2.2.0.jar代碼

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

同時它還需要依賴javax.persistence-2.2.0.jar, 這會導緻兩個jar中同時有：

javax.persistence.ValidationMode 和 javax.persistence.SharedCacheMode，…

D: 解決方法

在實體項目中(項目作了拆分,實體一個項目，接口一個項目，接口實作一個項目)，隻依賴：

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

接口實作項目中依賴的eclipselink改用：

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

這時jar由一個（eclipselink.jar）變成了5個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
