关联关系注解时报Could not determine type for错误的解决办法

检查所有的实体类的注解是不是都是统一写在属性上的，还是统一写在get方法上的。一定要统一。

另外如果要是所有实体类的id都是继承过来的，关键就要检查下这个id是不是跟其它注解是统一的。

如：

IdEntity.java

package com.bai.project.bean;import javax.persistence.Column;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.MappedSuperclass;@MappedSuperclasspublic abstract class IdEntity {protected Long id;//这里的注解跟下面那个类的不统一，就会报错@Id@GeneratedValue(strategy = GenerationType.IDENTITY)@Column(name="id")public Long getId() {return id;}public void setId(Long id) {this.id = id;}} 

Torganization.java

package com.bai.project.bean;import java.util.Date;import java.util.HashSet;import java.util.Set;import javax.persistence.CascadeType;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.FetchType;import javax.persistence.JoinColumn;import javax.persistence.ManyToOne;import javax.persistence.OneToMany;import javax.persistence.Table;import javax.persistence.Temporal;import javax.persistence.TemporalType;//这里的注解全部都是注解在属性上的，上面那个类是注解在方法上的。就会报错，统一一下就不会报错了。@Entity@Table(name = "sys_organization")public class Torganization extends IdEntity implements java.io.Serializable {@Column(name="O_createdatetime")private Date createdatetime;@Column(name="O_name")private String name;@Column(name="O_address")private String address;@Column(name="O_code")private String code;@Column(name="O_icon")private String icon;@Column(name="O_seq")private Integer seq;@ManyToOne(targetEntity=Torganization.class,cascade=CascadeType.ALL)@JoinColumn(name="O_organization_ID")private Torganization organization;@OneToMany(targetEntity=Torganization.class,cascade=CascadeType.ALL,mappedBy="organization")private Set<Torganization> organizations = new HashSet<Torganization>(0);public Torganization() {super();}public Torganization(Date createdatetime, String name, String address, String code, String icon, Integer seq,Torganization organization, Set<Torganization> organizations) {super();this.createdatetime = createdatetime;this.name = name;this.address = address;this.code = code;this.icon = icon;this.seq = seq;this.organization = organization;this.organizations = organizations;}public Torganization getOrganization() {return organization;}public void setOrganization(Torganization organization) {this.organization = organization;}public Date getCreatedatetime() {return createdatetime;}public void setCreatedatetime(Date createdatetime) {this.createdatetime = createdatetime;}public String getName() {return this.name;}public void setName(String name) {this.name = name;}public String getAddress() {return this.address;}public void setAddress(String address) {this.address = address;}public String getCode() {return this.code;}public void setCode(String code) {this.code = code;}public String getIcon() {return icon;}public void setIcon(String icon) {this.icon = icon;}public Integer getSeq() {return this.seq;}public void setSeq(Integer seq) {this.seq = seq;}public Set<Torganization> getOrganizations() {return organizations;}public void setOrganizations(Set<Torganization> organizations) {this.organizations = organizations;}}
