javax.persistence.UniqueConstraint.name()Ljava/lang/String

Question

创建类路径资源中定义的名为“sessionFactory”的 bean 时出错[ApplicationContext.xml]: 初始化方法调用失败；嵌套异常是 java.lang.NoSuchMethodError: javax.persistence.UniqueConstraint.name()Ljava/lang/String;

这有什么问题吗？

有人告诉我这是“hibernate-jpa-2.0-api-1.0.0.jar”和其他人之间的冲突。我该怎么做？谢谢!

Answer 1

此依赖项适用于 JPA 1:

<dependencies>
    <dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>1.0.2</version>
    <type>jar</type>
    <scope>provided</scope>
</dependency>

正如您在 JPA 1 中看到的 UniqueConstraint没有 name 属性，但在 JPA 2 中它在那里。您确实引用了“hibernate-jpa-2.0-api-1.0.0.jar”，这是 Hibernate 提供的 JPA 2.0 API。但是你的 pom.xml 不包含这样的文件。您可以通过向 pom 添加以下内容来包含该版本(或者实际上从来没有版本):

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.0-api</artifactId>
    <version>1.0.1.Final</version>
</dependency>

此外，您应该删除对 JPA 1 API 的依赖。
