JAVAee中的嵌套查询和嵌套结果具体要怎么实现，请写出具体的代码

好的，下面分别给出使用JDBC和Hibernate实现嵌套查询和嵌套结果的代码示例。

使用JDBC实现嵌套查询和嵌套结果的示例代码：

// 嵌套查询示例代码
String sql = "SELECT * FROM table1 WHERE id IN (SELECT id FROM table2 WHERE name = ?)";
PreparedStatement stmt1 = connection.prepareStatement(sql);
stmt1.setString(1, "test");
ResultSet rs1 = stmt1.executeQuery();
while (rs1.next()) {
    // 处理查询结果
}

// 嵌套结果示例代码
String sql2 = "SELECT * FROM table1 WHERE id = ?";
PreparedStatement stmt2 = connection.prepareStatement(sql2);
stmt2.setInt(1, 1);
ResultSet rs2 = stmt2.executeQuery();
while (rs2.next()) {
    int id = rs2.getInt("id");
    String name = rs2.getString("name");
    // 使用前一个查询的结果进行嵌套查询
    String sql3 = "SELECT * FROM table2 WHERE id = ?";
    PreparedStatement stmt3 = connection.prepareStatement(sql3);
    stmt3.setInt(1, id);
    ResultSet rs3 = stmt3.executeQuery();
    while (rs3.next()) {
        String desc = rs3.getString("desc");
        // 处理查询结果
    }
}

使用Hibernate实现嵌套查询和嵌套结果的示例代码：

// 嵌套查询示例代码
Criteria criteria1 = session.createCriteria(Table1.class);
DetachedCriteria subCriteria = DetachedCriteria.forClass(Table2.class)
    .add(Restrictions.eq("name", "test"))
    .setProjection(Projections.property("id"));
criteria1.add(Property.forName("id").in(subCriteria));
List<Table1> result1 = criteria1.list();

// 嵌套结果示例代码
Criteria criteria2 = session.createCriteria(Table1.class);
criteria2.add(Restrictions.eq("id", 1));
List<Table1> result2 = criteria2.list();
for (Table1 table1 : result2) {
    int id = table1.getId();
    String name = table1.getName();
    // 使用前一个查询的结果进行嵌套查询
    Criteria criteria3 = session.createCriteria(Table2.class);
    criteria3.add(Restrictions.eq("id", id));
    List<Table2> result3 = criteria3.list();
    for (Table2 table2 : result3) {
        String desc = table2.getDesc();
        // 处理查询结果
    }
}

以上代码仅作为示例，实际使用中需要根据具体情况进行调整。
