使用lombok固然能加快开发,但是使用的不恰当,可能会给我们造成一些意外的伤害,这里我将之前遇到的字段伤害做个简单的总结。

数据库设计的时候,一定要考虑好字段的名称,让它和json一致 ,比如我的数据库中设计的为 IsTmail ,那么我使用的lombok字段名 为 IsTmail(因为数据库映射是完全根据字段对应的,与json没有关系,但是我们以后设计尽量和json一致)

lombok 首字母映射出来一定是大写的(映射出来json也是如此)

javabean 首字母小写,第二个大写,则set的下个字母按照原来的首字母确定(映射出来的json和自己本身的字段名相同)

1、关于boolean的字段


//javabean isTmail 、IsTmail谁在前面用谁的 setTmail isTmail
  {
        "tmail": true
  }
   
// lomboke 如果是小写的is
	private boolean isTmail; //lombok setTmail     isTmail
	private boolean IsTmail; //lombok setIsTmail   isIsTmail
	
	{
		"isTmail": true,  //IsTmail
		"tmail": true     //isTmail
	}
	
	
	//下面这个 JavaBean和lombok是一样的
	private boolean healerJean ; //boolean类型的时候 setHealerJean   isHealerJean
  {
		"healerJean": true,
	}

2、关于第二个字母大写,首字母大小写问题

//lombok  tVolumn TVolumn  谁在前使用谁 setTVolumn  getTVolumn
	{
		"TVolumn": 100,
	}
	
	
  private Long tVolumn ;  //JavaBean settVolumn
  private Long TVolumn;   //JavaBean setTVolumn
	{
     "TVolumn": 0,
     "tVolumn": 0,
  }
