数据库中的数据表：

create table client

(

????? clientId???? int identity(1,1),

????? clientName??????? varchar(100)

)

?

创建返回对象类：

public class client

{

????? private Integer clientId;

????? private String clientName;

?

????? public client()

???? {

???? }

?

????? public Integer getClientId() {
?? ??? ?return this.clientId;
?? ?}

?? ?public void setClientId(Integer clientId) {
?? ??? ?this.clientId = clientId;
?? ?}

?? ?public String getClientName() {
?? ??? ?return this.clientName;
?? ?}

?? ?public void setClientName(String clientName) {
?? ??? ?this.clientName = clientName;
?? ?}

}

使用spring的jdbcTemplate查询返回对象

XmlBeanFactory factory = new XmlBeanFactory(new ClassPathResource("bean.xml"));

org.springframework.jdbc.core.JdbcTemplate template = (org.springframework.jdbc.core.JdbcTemplate) factory.getBean("jdbcTemplate");

java.util.List<client> list = (java.util.List<hbconfig.client>)template.query(
??? ??? ??? ??? "select * from client", new ResultSetExtractor() {

??? ??? ??? ??? ??? public Object extractData(ResultSet arg0)
??? ??? ??? ??? ??? ??? ??? throws SQLException, DataAccessException {
??? ??? ??? ??? ??? ??? java.util.List<hbconfig.Client> list = new java.util.ArrayList<Client>();
??? ??? ??? ??? ??? ??? while (arg0.next()) {
??? ??? ??? ??? ??? ??? ??? client c = new client();
??? ??? ??? ??? ??? ??? ??? c.setClientId(arg0.getInt("clientId"));
??? ??? ??? ??? ??? ??? ??? c.setClientName(arg0.getString("clientName"));
??? ??? ??? ??? ??? ??? ??? list.add(c);
??? ??? ??? ??? ??? ??? }
??? ??? ??? ??? ??? ??? return list;
??? ??? ??? ??? ??? }

??? ??? ??? ??? });
??? ??? for(hbconfig.Client c : list)
??? ??? {
??? ??? ??? System.out.println(c.getClientName());
??? ??? }
