解决方案

我会说你应该避免使用表名这是保留字，与休眠。当然你可以逃避它，但它可能会在将来引发问题（例如在查询中）。所以最安全的方法是以另一种方式命名表 - 例如 users

  @Entity 
 @Table（name =users）
 public class Signup {
} 
  

i tried to save data in to table by spring but this error show when data submitted..

org.springframework.beans.NotReadablePropertyException: Invalid property 'user' of bean class [com.jit.model.Signup]: Bean property 'user' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

           Session session= HiberSession.getHiber();

解决方案

I'd say that you should avoid having table names that are reserved words, with hibernate. Sure you can escape it, but it may cause problems in the future (in a query for example). So the safest way is to name the table another way - say users

@Entity
@Table(name="users")
public class Signup {
}
