如何在Spring Prepared Statement中传递Java Date

Question

如果我有一个Java Date，并且使用JDBCTEmplate我想在预准备语句中使用它，这是正确的语法吗？

Date x = new Date();

...

String SQL = "select a.1, a.2 from b JOIN a ON b.id = a.b_id where b.name = ? and a.type = ? and a.date = ?";

A istance = jdbcTemplate.queryForObject(SQL, new Object[]{variable_1, variable_2, x}, new aAndbMapper());

或者我应该写：

String SQL = "select a.1, a.2 from b JOIN a ON b.id = a.b_id where b.name = ? and a.type = ? and DATE(a.date) = ?";

Answer 1

第一个是一个不错的选择，但我会在没有自定义映射器的情况下完成：

String SQL = "select a.1, a.2 from b JOIN a ON b.id = a.b_id where b.name = ? and a.type = ? and a.date = ?";

A istance = getJdbcTemplate().queryForObject(SQL, new Object[]{variable_1, variable_2, x}, new BeanPropertyRowMapper(A.class));
