我试图测试一个组合的主键,不幸的是有些东西运行不正确。
包含组合主键的课程类
@Entity(name = "Course")
public class Course {
@EmbeddedId
private PkCourse pkCourse;
public Course() {}
public Course( PkCourse pkCourse) {
this.pkCourse = pkCourse;
}
public PkCourse getPkCourse() {
return pkCourse;
}
public void setPkCourse( PkCourse pkCourse ) {
this.pkCourse = pkCourse;
}
}
表示组合主键的类
@Embeddable
public class PkCourse implements Serializable {
@Column(name = "courseName")
private String courseName;
@Column(name = "courseGrade")
private Integer grade;
PkCourse(){
}
public PkCourse( String courseName, Integer grade ) {
this.courseName = courseName;
this.grade = grade;
}
public String getCourseName() {
return courseName;
}
public void setCourseName( String courseName ) {
this.courseName = courseName;
}
public Integer getGrade() {
return grade;
}
public void setGrade( Integer grade ) {
this.grade = grade;
}
@Override
public boolean equals( Object o ) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
PkCourse pkCourse = (PkCourse) o;
return courseName.equals(pkCourse.courseName) &&
Objects.equals(grade, pkCourse.grade);
}
@Override
public int hashCode() {
return Objects.hash(courseName, grade);
}
}
我的测试程序
private void composedPrimaryKey() {
PkCourse composedPK = new PkCourse("database", 3);
Course course = new Course(composedPK);
courseRepository.save(course);
}
我的 jpa repository
public interface CourseRepository extends JpaRepository<Course, PkCourse> {
}
我得到的例外
原因:org.springframework.dao.InvalidDataAccessResourceUsageException: 無法提取 ResultSet;SQL [n/a];嵌套异常是 org.hibernate.exception.SQLGrammarException: 无法提取 ResultSet
原因:Java . SQL . sqlsyntaxerrorexception:表“company.course”不存在

我通过用一个字符串属性替换整数属性< code>grade解决了创建课程表的问题。

有人能解释一下为什么不同类型的两个属性不能工作吗?(在我的第一个例子中是字符串和整数)。
编辑3
另外,我通过修改注释解决了我的问题
@Column(name = "courseName")
private String courseName;
自
@Column(name = "courseName", length = 20)
private String courseName;
我尝试了基于异常行的此修改
原因:java.sql.SQLSyntaxErrorException:指定的密钥太长;最大密钥长度为1000字节
有人能解释一下这背后的魔力吗?
如果你看看DDL
create table course (
course_name varchar(255) not null,
course_grade integer not null,
primary key (course_name, course_grade)
) engine=MyISAM" via JDBC Statement
MyISAM
表中索引的值的大小有限制,此默认大小也是MySQL的相关版本
现在,创建此类表的理想方法不是使用course_name
和course_grade
作为主键,而是应该使用uuid
或auto gen id
,然后在course_name
和course_grade
的组合上放置唯一索引。
如果您仍然遇到问题,您还可以尝试此答案中提到的线程中提到的其他修复程序
> < Li > < p > < code > SET @ @ global . innodb _ large _前缀= 1;
升级到更高的 MySQL 版本 5.7
设置全局存储_engine='InnoDb'
