我正在监视由datables进行的sql查询，因为我的一些字段是blob类型。我意识到即使我用render =＆＃34; false＆＃34;修改我的list.jspx。排序=＃＆34;假＆＃34;搜索=＃＆34;假＆＃34; mysql查询正在选择此字段：
Hibernate：选择empleado0_.id为id1_0_，empleado0_.foto为 foto2_0_，empleado0_.fotocurp为fotocurp3_0_， empleado0_.foto_miniatura为foto_min4_0_，empleado0_.nombre as nombre5_0_，empleado0_.version作为版本6_0_来自empleado empleado0_ 哪个较低（empleado0_.nombre）喜欢？逃避＆＃39;！＆＃39;要么 低（empleado0_.fotocurp）喜欢？逃避＆＃39;！＆＃39;限制？
我正在寻找这个方法，它看起来像是在我的Controller类中执行查询的点：
arr1 = ["sound", "speaker", "volume", "audio", "earphone", "earphones",
"headphones", "headphone"]
arr2 = ["battery", "charge", "charged", "low"]
problem = "my battery is not working"
if any(keyword in problem.split() for keyword in arr1):
print('Problem is related to sound.')
if any(keyword in problem.split() for keyword in arr2):
print('Problem is related to battery.')
但是我无法弄清楚如何避免查询选择不必要的重字段。
