Reason:

The annotation @Column name property is given the same value for two fields.


@Column(name = "ID")
private String id;

@Column(name = "ID")
private String name;

Solution:

Provide unique name for the column name.

@Column(name = "ID")
private String id;

@Column(name = "NAME")
private String name;
