我正在尝试在 mysql 表 testdata 中插入数据。
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Table;
import org.springframework.data.annotation.Id;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Table;
import org.springframework.data.annotation.Id;
@Entity
@Table(name = "testdata")
public class testdata {
@Id
@Column(name = "image_id")
private String image_id;
@Column(name = "post_id")
String post_id;
@Column(name = "image")
String image;
public String getPost_id() {
return post_id;
}
public void setPost_id(String post_id) {
this.post_id = post_id;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getImage_id() {
return image_id;
}
public void setImage_id(String image_id) {
this.image_id = image_id;
}
public testdata(String post_id, String image, String image_id) {
super();
this.post_id = post_id;
this.image = image;
this.image_id = image_id;
}
}
public String getPost_id() {
return post_id;
}
public void setPost_id(String post_id) {
this.post_id = post_id;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getImage_id() {
return image_id;
}
public void setImage_id(String image_id) {
this.image_id = image_id;
}
public testdata(String post_id, String image, String image_id) {
super();
this.post_id = post_id;
this.image = image;
this.image_id = image_id;
}
当我运行我的项目时出现以下异常
springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.demo.service.ServiceInterface com.demo.controller.UserController.service; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'service': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.demo.dao.UserDao com.demo.service.ServiceImpl.dao; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDaoImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory com.demo.dao.UserDaoImpl.sessionFactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in com.demo.conf.HibernateConfiguration: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: No identifier specified for entity: com.demo.model.testdata
但是如果我删除@Entity 项目运行成功。但数据没有插入。 是否可以在没有 hibernate 的情况下使用其他方法插入数据。 如果有人对此有所了解,我将不胜感激。
最佳答案
您没有为 Id
注释指定 javax.persistence
包。
替换
import org.springframework.data.annotation.Id;
由
import javax.persistence.Id;
