[BUG] a user generated multiple ip session, the query error

[qiaozhanwei]

SessionMapper :

/**
* query by user id and ip
* @param userId
* @return
*/
@results(value = {
@Result(property = "id", column = "id", id = true, javaType = String.class, jdbcType = JdbcType.VARCHAR),
@Result(property = "userId", column = "user_id", javaType = int.class, jdbcType = JdbcType.INTEGER),
@Result(property = "ip", column = "ip", javaType = String.class, jdbcType = JdbcType.VARCHAR),
@Result(property = "lastLoginTime", column = "last_login_time", javaType = Timestamp.class, jdbcType = JdbcType.DATE)
})
@SelectProvider(type = SessionMapperProvider.class, method = "queryByUserId")
Session queryByUserId(@param("userId") int userId);

Update:

/**
* query by user id and ip
* @param userId
* @return
*/
@results(value = {
@Result(property = "id", column = "id", id = true, javaType = String.class, jdbcType = JdbcType.VARCHAR),
@Result(property = "userId", column = "user_id", javaType = int.class, jdbcType = JdbcType.INTEGER),
@Result(property = "ip", column = "ip", javaType = String.class, jdbcType = JdbcType.VARCHAR),
@Result(property = "lastLoginTime", column = "last_login_time", javaType = Timestamp.class, jdbcType = JdbcType.DATE)
})
@SelectProvider(type = SessionMapperProvider.class, method = "queryByUserId")
List queryByUserId(@param("userId") int userId);
