这次是hibernate的注解问题@JoinColumn有点小问题。

直接上代码吧

package crazyit.app.domain;



import java.util.ArrayList;

import java.util.List;



import javax.persistence.CollectionTable;

import javax.persistence.Column;

import javax.persistence.ElementCollection;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import javax.persistence.OrderColumn;

import javax.persistence.Table;



@Entity

@Table(name="person_inf")

public class Person {

	@Id @Column(name="person_id")

	@GeneratedValue(strategy=GenerationType.IDENTITY)

	private Integer id;

	private String name;

	private int age;

	@ElementCollection(targetClass=String.class)

	@CollectionTable(name="school_inf",joinColumns=@JoinColumn(name="person_id",nullable=false))

	@Column(name="school_name")

	@OrderColumn(name="list_order")

	private List<String> schools=new ArrayList<>();

	



}

报错是在@CollectionTable(name="school_inf",joinColumns=@JoinColumn(name="person_id",nullable=false))
@JoinColumn报错说：JoinColumn cannot be resolved to a type
ide是Javaee的eclipse 官网下的比较新的版本 jdk是最新的。相关包如下图
