jdbcTemplate查询返回对象或集合

jdbcTemplate查询返回对象或者集合时，官方没有完全封装，只是封装了部分，需要我们自己手动完成
对象绑定，实现RowMapper接口即可，以下是示例代码：

/** * jdbc查询结构返回对象 * @throws Exception */@Testpublic void testQueryForObject() throws Exception{    String sql = "select id,id_card，FAMILY_MEMBER_NAME from FAMILY_MEMBER fm  where ID_CARD = ? ";    String id = "620100199808066868";    FamilyMember familyMember = jdbcTemplate.queryForObject(sql, new Object[]{id}, new MyRowMapper());    System.out.println(familyMember);}/** * jdbc查询结构返回集合 * @throws Exception */@Testpublic void testQueryForList() throws Exception{    String sql = "select id,id_card，FAMILY_MEMBER_NAME from FAMILY_MEMBER fm  where FAMILY_MEMBER_NAME like ? ";    String name = "%小红%";    List<FamilyMember> familyMemberList = jdbcTemplate.query(sql, new Object[]{name}, new MyRowMapper());    for (FamilyMember familyMember : familyMemberList) {        System.out.println(familyMember);    }}class MyRowMapper implements RowMapper<FamilyMember>{    @Override    public FamilyMember mapRow(ResultSet resultSet, int i) throws SQLException {        FamilyMember familyMember = new FamilyMember();        familyMember.setId(resultSet.getString(1));        familyMember.setIdCard(resultSet.getString(2));        familyMember.setFamilyMemberName(resultSet.getString(3));        return familyMember;    }}
