在写Java后台的数据返回值时报错：
错误提示如下：
Type Exception Report
Message Request processing failed; nested exception is org.springframework.dao.DataIntegrityViolationException: Error attempting to get column 'state' from result set. Cause: org.postgresql.util.PSQLException: 不良的类型值 int : t
Description The server encountered an unexpected condition that prevented it from fulfilling the request.

根据错误提示，发现这是因为我的pojo(实体类)的字段与数据库的字段类型不一致造成的
state我在数据库中写的是boolean类型，在实体类中写成了int,因此报错
