Unknowncolumn'*'in'fieldlist'異常解決

在使用Hibernate做持久化的時候，為實體類定義一個與資料表無關的屬性。

出現異常如下：

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column `user0_.authority` in `field list`

解決方式:

在屬性的方法get上加入@Transient

        
        @Transient 
	public Authority getAuthority() {
		return authority;
	}
