java - JPA/hibernate java.lang.NoSuchMethodError

Question

错误信息

Oct 20, 2015 10:56:33 PM org.hibernate.dialect.Dialect INFO: HHH000400: Using dialect: org.hibernate.dialect.PostgreSQL9Dialect Oct 20, 2015 10:56:33 PM org.hibernate.engine.jdbc.internal.LobCreatorBuilder useContextualLobCreation INFO: HHH000424: Disabling contextual LOB creation as createClob() method threw error : java.lang.reflect.InvocationTargetException Exception in thread "main" java.lang.NoSuchMethodError: javax.persistence.JoinColumn.foreignKey()Ljavax/persistence/ForeignKey;

我知道是 several questions here about this ，但正如他们中的大多数人所说，他们要求确保我使用的是 hibernate 4.3+ 和 JPA2.1+。而且我相信我正在使用它们:

这是我的persistence.xml

最后是 BarEntity 的一个例子

@Entity
public class BarEntity implements Serializable {

    @Id
    @GeneratedValue
    private long id;

    @ManyToOne
    @JoinColumn(name = "fooId", referencedColumnName = "id")
    @Cascade({CascadeType.SAVE_UPDATE})
    private Foo foo;

    @Column(nullable = false, unique = true)
    private String bar;

    @Column(nullable = false)
    private String foobar;
}

我该怎么做才能部署它？

很抱歉无法将 pom.xml/persistence.xml 简化为更通用的内容，因为我不确定错误在哪里。

Answer 1

正如 Zhao 所说和 hermitmaster这绝对是一个依赖问题。但是，我相信对于经验不足的人来说，很难弄清楚什么应该匹配/可能是错误的。

所以，这是检查这个的方法

pom.xml中的相关数据为:

    <artifactId>hibernate-entitymanager</artifactId>
    <version>4.3.1.Final</version>
    (...)
    <artifactId>hibernate-jpa-2.1-api</artifactId>
    <version>1.0.0.Final</version>
    (...)
    <artifactId>hibernate-jpamodelgen</artifactId>
    <version>5.0.2.Final</version>

正如用户所说，hibernate 需要 4.3 或更高版本，他是正确的。但是，它应该使用相同版本的 hibernate 和 jpamodelgen。

hibernate-entitymanager 和 hibernate-jpamodelgen 应该有相同的编号。就这样吧:

4.3.1 或 5.0.2。
