实体继承注解的困惑

Question

当类Garden中有userList属性时启动异常，求解决，需要使用继承方式
用到的类：import java.io.Serializable;import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Inheritance;
import javax.persistence.InheritanceType;@SuppressWarnings("serial")
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class BaseEntity implements Serializable { private String id;
private String name;

@Id
public String getId() {
return id;
} public void setId(String id) {
this.id = id;
} public String getName() {
return name;
} public void setName(String name) {
this.name = name;
}}import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;@SuppressWarnings("serial")
@Entity
@Table(name = "GARDEN")
public class Garden extends BaseEntity { private String address;
private String postCode;
@OneToMany(cascade = { CascadeType.ALL }, mappedBy = "garden", fetch = FetchType.LAZY)
private List<GardenUser> userList; public List<GardenUser> getUserList() {
return userList;
} public void setUserList(List<GardenUser> userList) {
this.userList = userList;
} public String getAddress() {
return address;
} public void setAddress(String address) {
this.address = address;
} public String getPostCode() {
return postCode;
} public void setPostCode(String postCode) {
this.postCode = postCode;
}}import javax.persistence.Entity;
import javax.persistence.ManyToOne;
import javax.persistence.Table;@SuppressWarnings("serial")
@Entity
@Table(name = "GARDEN_USER")
public class GardenUser extends BaseEntity { private String location;
private Boolean isAdmin;
@ManyToOne
private Garden garden; public String getLocation() {
return location;
} public void setLocation(String location) {
this.location = location;
} public Boolean getIsAdmin() {
return isAdmin;
} public void setIsAdmin(Boolean isAdmin) {
this.isAdmin = isAdmin;
} public Garden getGarden() {
return garden;
} public void setGarden(Garden garden) {
this.garden = garden;
}}异常如下：

Answer 1

Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]:很明显的错误Could not determine type for: java.util.List, for columns: [org.hibernate.mapping.Column(userList)]
没有确定的类型为java.util.List 为列userList看看applicationContext.xml里面的配置

Answer 2

一对多的话也不能这样设置吧！   换成是hbm.xml的话也不是这样写 的吧！
