JPA Multiple writable mappings exist for the field [{0}]. Only one may be defined as writable, all o

使用JPA进行数据操作，在ManyToOne 和OneToMany中，很容易遇到如下问题。

遇到的问题：Multiple writable mappings exist for the field [{0}]. Only one may be defined as writable, all others must be specified read-only.

解决方案是：在 @JoinColumn中加入updatable=false,insertable=false

       @ManyToOne(optional=false)
@JoinColumn(name="RECORD_ID",nullable=false, updatable=false,insertable=false)
private Record record;
