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>{@Overridepublic 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;}}
