前些天發現了一個巨牛的人工智能學習網站，通俗易懂，風趣幽默，忍不住分享一下給大家。點擊跳轉到教程。

報錯如題：

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 ... ...

情況1. 項目用的 spring-data-jpa 。

原本對于表和本類的每個字段都有給注解 @Colum 來對應，其實不用給也可以。把這些注解注釋掉工程就可以正常啟動了。

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;/*** 解凍申請*/ @Entity(name = "unfreeze") @Table(name = "unfreeze_apply") @JsonIgnoreProperties(ignoreUnknown = true) public class UnfreezeApply implements Serializable {private static final long serialVersionUID = -1826761763082698565L;@Id@GeneratedValue(strategy = GenerationType.AUTO)private Integer id;// @Column(name = "employee_no", nullable = false)private String employeeNo;@Transientprivate String employeeName; //員工名稱@ManyToOne(fetch = FetchType.EAGER)@JsonIgnore // @JoinColumn(name="employee_no", referencedColumnName="usernumber", insertable=false, updatable=false)private User employee;// @Column(name = "reason", nullable = false)private String reason;}

啟動成功：

情況2. （網上的其它情況）

?

當有一個物理表映射兩個或多個邏輯表名稱時，會發生此異常。如?因為那里有多個@JoinColumns使用相同的列名（user_id）

為每個JoinColumns（在注釋中的name參數中定義）設置一個不同的名稱：

@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; }
