Question

我们得到了Eclipse错误（来自JPA Problem验证程序），如下所示：

Attribute override "<myAttrName>" cannot be resolved to an attribute on the embeddable "..."

在某些JPA属性上使用embeddable（也可能类似mapped super class）我们想要正确覆盖，例如像这样：

@Embeddable
public class DaoUsrMod {

    @ManyToOne( fetch = FetchType.LAZY )
    @JoinColumn( name = "u_lmod_id" , insertable = false , updatable = false )
    private DaoUser usr ;
    ...
}


@Entity
public class DaoFoo {

    @Embedded
    @AttributeOverrides( {
        @AttributeOverride( name = "usr" ,  column = @Column( name = "u_created_id" ) )
    } )
    private DaoUsrMod                                               usrModAngel ;

    ...
}

这似乎是一个Eclipse bug，所以你可以在这里将这种类型的ERROR改为不太显性的级别（我们将其改为WARNING）（对于Eclipse Neon）：

Project -> Properties -> JPA -> Errors/Warnings -> Database 
  -> Attribute/association overrides
    (2nd entry:)
    -> Attribute override name cannot be resolved to an attribute: [Error]

e.g。到：

  -> Attribute override name cannot be resolved to an attribute: [Warning]
