Question

如果我从代码中删除@Table注释，代码就会成功运行，并且我已经检查了与此错误相关的所有其他问题，但找不到任何解决方案。

UserDetails.java

package org.javabrains.faisal.dto;
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {

    @Id
    private int userId;

    public Date getJoinDate() {
        return joinDate;
    }

    public void setJoinDate(Date joinDate) {
        this.joinDate = joinDate;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    private String userName;

    private Date joinDate;

    private String address;

    private String description;

    public int getUserId() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

}

HibernateTest.java

package org.javabrain.faisal.hibernate;
import java.util.Date;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.javabrains.faisal.dto.UserDetails;

public class HibernateTest {

    public static void main(String[] args) {
        UserDetails user=new UserDetails();

        user.setUserId(3);
        user.setUserName("Raza 3");

        user.setAddress("goplganj");
        user.setDescription("from Jamia and TCS");
        user.setJoinDate(new Date());

        SessionFactory sessionFactory= new Configuration().configure().buildSessionFactory();
        Session session =sessionFactory.openSession();

        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();



    }

Answer 1

您需要将hibernate-jpa-2.1-api-1.0.0.Final.jar添加到类路径中。

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.1-api</artifactId>
    <version>1.0.0.Final</version>
</dependency>

版本2.1中添加了

Table#indexes()方法。因此，类路径中的@Table注释具有不正确的jar（对于示例版本2.0）。它可以位于应用程序服务器的默认lib文件夹或Web容器中。

<强>解决方案

@Table中存在错误的persistence-api-1.0.jar注释。因此需要从类路径中删除此jar。 hibernate-jpa-2.1-api-1.0.0.Final.jar包含persistence-api-1.0.jar的所有注释。

Answer 2

您的服务器库中肯定有jpa2.0 jar。要检查这一点，您需要解压缩所有服务器jar（特别是jee jar）并在名为javax.persistence的包中查找Table.class。

线程“main”中的异常java.lang.NoSuchMethodError：javax.persistence.Table.indexes（）[Ljavax / persistence / Index;
