JPA 下使用原生sql，参数传递及使用方式以及hibernate参数传递使用方式

1、原生sql
参数为对象
@Query(value = "select * from user_info where username = :#{#user.username} , nativeQuery= true)
User findByUsername(User user);

参数为变量，使用?获取
@Query(value = "select * from user_info where username = ?1 , nativeQuery = true)
User findByUsername(String username);

参数为变量，使用形参名访问
@Query(value = "select * from user_info where username = :username , nativeQuery = true)
User findByUsername(String username);

2、hibernate
参数为对象
@Query(value = "select u from user_info u where u.username = :#{#user.username} , nativeQuery = true)
User findByUsername(User user);

参数为变量，使用?获取
@Query(value = "select u from user_info u where u.username = ?1, nativeQuery = true)
User findByUsername(String username);

参数为变量，使用形参名访问
@Query(value = "select u from user_info u where u.username = :username , nativeQuery = true)
User findByUsername(String username);
