使用Spring JDBC在外表中插入数据

Question

我的MySQL数据库中有两个表：

CREATE TABLE table1 (
  id int auto_increment,
  name varchar(10),
  CONSTRAINT pk_id primary key(id)
) 

CREATE TABLE table2 (
  id_fk int,
  stuff varchar(30),
  CONSTRAINT fk_id FOREIGN KEY(id_fk) REFERENCES table1(id) 
) 

    SimpleJdbcInsert insert1 = new SimpleJdbcInsert(this.getDataSource())
        .withTableName("table1")
        .usingColumns("name");

    Map<String, Object> parameters1 = new HashMap<String, Object>();
    parameters1.put("name", myObj1.getStuff());
    insert.execute(parameters1);

    SimpleJdbcInsert insert2 = new SimpleJdbcInsert(this.getDataSource())
        .withTableName("table2")
        .usingColumns("stuff");

    Map<String, Object> parameters2 = new HashMap<String, Object>();
    parameters2.put("stuff", myObj2.getStuff());
    insert.execute(parameters2);

另外，如何获取给定名称的数据？

任何帮助都是非常感谢的！

请看这个简单的示例，类测试中的所有方法都是事务性的，更多信息请阅读Spring Framework文档

@Transactional
public class Test {
    @Autowired
    DataSource ds;

    public void test1() throws Exception {
        Map<String, Object> params = new HashMap<String, Object>();
        params.put("c1", "test");
        SimpleJdbcInsert insert = new SimpleJdbcInsert(ds).withTableName("t1").usingColumns("c1")
                .usingGeneratedKeyColumns("id");
        long id = insert.executeAndReturnKey(params).longValue();

    params = new HashMap<String, Object>();
    params.put("stuff", "stuff");
    params.put("id_fk", id);
    SimpleJdbcInsert insert2 = new SimpleJdbcInsert(ds).withTableName(
            "table2").usingColumns("stuff", "id_fk");
    insert2.execute(params);

        NamedParameterJdbcTemplate tmpl = new NamedParameterJdbcTemplate(ds);
        params = new HashMap<String, Object>();
        params.put("id", id);
        String c1 = tmpl.queryForObject("select c1 from t1 where id = :id", params, String.class);
    }
