The error states you are missing something on the updateTime attribute of the Customer entity. Because it is a java.util.Date, JPA needs you to specify if you want it treated like a java.sql.Date or java.sql.Timestamp as it can go either way: " A temporal type must be specified for persistent fields or properties of type java.util.Date and java.util.Calendar.".

For example:
@Version
@Column(name = "LAST_UPDATE")
@Temporal(TemporalType.TIMESTAMP)
private Date updateTime;

Is probably what you want since you are using it as a version field.
