报错如题
Caused by: org.hibernate.DuplicateMappingException: Table [xxx] contains physical column name [comment] referred to by multiple physical column names: [comment], [auditComment]at org.hibernate.boot.internal.InFlightMetadataCollectorImpl$TableColumnNameBinding.bindPhysicalToLogical(InFlightMetadataCollectorImpl.java:922)at org.hibernate.boot.internal.InFlightMetadataCollectorImpl$TableColumnNameBinding.addBinding(InFlightMetadataCollectorImpl.java:891)at org.hibernate.boot.internal.InFlightMetadataCollectorImpl.addColumnNameBinding(InFlightMetadataCollectorImpl.java:961)at org.hibernate.boot.internal.InFlightMetadataCollectorImpl.addColumnNameBinding(InFlightMetadataCollectorImpl.java:942)at ... ... 情况1. 项目用的 spring-data-jpa 。
原本对于表和本类的每个字段都有给注解 Colum 来对应其实不用给也可以。把这些注解注释掉工程就可以正常启动了。
如下 import org.codehaus.jackson.annotate.JsonIgnore;
import org.codehaus.jackson.annotate.JsonIgnoreProperties;
import org.codehaus.jackson.map.annotate.JsonSerialize;import javax.persistence.*;
import java.io.Serializable;
import java.util.Date;/*** 解冻申请*/
Entity(name unfreeze)
Table(name unfreeze_apply)
JsonIgnoreProperties(ignoreUnknown true)
public class UnfreezeApply implements Serializable {private static final long serialVersionUID -1826761763082698565L;IdGeneratedValue(strategy GenerationType.AUTO)private Integer id;// Column(name employee_no, nullable false)private String employeeNo;Transientprivate String employeeName; //员工名称ManyToOne(fetch FetchType.EAGER)JsonIgnore
// JoinColumn(nameemployee_no, referencedColumnNameusernumber, insertablefalse, updatablefalse)private User employee;// Column(name reason, nullable false)private String reason;}
启动成功 情况2. 网上的其它情况 当有一个物理表映射两个或多个逻辑表名称时会发生此异常。如 因为那里有多个JoinColumns使用相同的列名user_id
为每个JoinColumns在注释中的name参数中定义设置一个不同的名称
OneToOne
JoinColumn(name local_user_id)
public User getUser() {return user;
}OneToOne
JoinColumns({JoinColumn(name userId, referencedColumnName userId),JoinColumn(name providerId, referencedColumnName providerId),JoinColumn(name providerUserId, referencedColumnName providerUserId)}
)
public UserConnection getUserConnection() {return userConnection;
