上下文初始化期间遇到异常 - 使用 Java 配置配置 HibernateTemplate Bean 时

问题描述 投票：0回答：2

无法配置hibernate获取上下文初始化异常，已经尝试了Hibernate依赖项的替代版本，虽然该表是在DB中创建的，但我认为存在一些与Bean相关的问题。

学生实体

package com.spring.orm.Entity;

import jakarta.persistence.Column;
import jakarta.persistence.Entity;
import jakarta.persistence.Id;
import jakarta.persistence.Table;

@Entity
@Table(name = "student")
public class Student {

    @Id
    @Column(name = "student_id")
    private long studentId;
    @Column(name = "student_name")
    private String studentName;
    @Column(name = "student_city")
    private String studentCity;
    
    public long getStudentId() {
        return studentId;
    }
    public void setStudentId(long studentId) {
        this.studentId = studentId;
    }
    public String getStudentName() {
        return studentName;
    }
    public void setStudentName(String studentName) {
        this.studentName = studentName;
    }
    public String getStudentCity() {
        return studentCity;
    }
    public void setStudentCity(String studentCity) {
        this.studentCity = studentCity;
    }
    public Student() {
    }
    public Student(long studentId, String studentName, String studentCity) {
        this.studentId = studentId;
        this.studentName = studentName;
        this.studentCity = studentCity;
    }

}

学生道

package com.spring.orm.Dao;

import com.spring.orm.Entity.Student;

public interface StudentDao {

    public Student insert(Student student);

}

学生Dao实现

package com.spring.orm.Dao.Impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate5.HibernateTemplate;

import com.spring.orm.Dao.StudentDao;
import com.spring.orm.Entity.Student;

public class StudentDaoImpl implements StudentDao{

    @Autowired
    private HibernateTemplate hibernateTemplate;
    
    @Override
    public Student insert(Student student) {
        Student st = (Student) hibernateTemplate.save(student);
        return st;
    }

}

无法配置休眠模板

Hibernate 在引入 jakarta.annotations-api 之前就放弃了 Criteria-api。欢迎来到依赖地狱！

这就是为什么 

 中的
hibernate5

导入org.springframework.orm.hibernate5.HibernateTemplate;

但是你的 pom 有 hibernate 版本 6x。

改用此依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>2.7.18</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>5.6.15.Final</version>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-dbcp</artifactId>
        <version>9.0.80</version>
    </dependency>
    <dependency>
        <groupId>com.mysql</groupId>
        <artifactId>mysql-connector-j</artifactId>
        <version>8.3.0</version>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>3.8.1</version>
        <scope>test</scope>
    </dependency>
</dependencies>

顺便说一句：

spring-data-jpa
也可暂时绑定兼容的
spring-core
、
spring-orm
和
spring-context
。

发布这个问题后，我在不同的论坛上寻找答案，但通过简单的谷歌搜索，我知道在 spring 5+ 版本中，HibernateTemplate 已被弃用，而是我们应该直接在“Student Dao Impl”中注入 

sessionFactory
对象' 这对我有用。

更新了休眠配置

package com.spring.orm.Config;

        System.out.println("Configured datasource");
        return dataSource;

    @Bean

        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(getDataSource());
        sessionFactory.setHibernateProperties(getHibernateProperties());
        sessionFactory.setPackagesToScan("com.spring.orm.Entity");

        return sessionFactory;
    }

    @Bean
    public HibernateTransactionManager transactionManager() {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();

    public StudentDaoImpl getStudentDao(){
        StudentDaoImpl studentDaoImpl = new StudentDaoImpl();
        return studentDaoImpl;

更新了 Student Dao Impl 

package com.spring.orm.Dao.Impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.Transactional;

import com.spring.orm.Dao.StudentDao;
import com.spring.orm.Entity.Student;


@Repository
@Transactional
@EnableTransactionManagement
public class StudentDaoImpl implements StudentDao{

    @Autowired
    private SessionFactory sessionFactory;


    @Override
    public void insert(Student student) {
        sessionFactory.getCurrentSession().persist(student);
    }


    @Override
    public void deleteStudentById(int id) {
        Student st = new Student();
        st.setStudentId(id);
        sessionFactory.getCurrentSession().remove(st);
    }


    // public void setSessionFactory(SessionFactory sessionFactory) {
    //     this.sessionFactory = sessionFactory;
    // }
    
}

其余所有文件都是一样的
