两种方法测试spring中的jdbc
  JDBC是一个非常基础的数据存取API,spring对其进行简单的封装,  下面以sqlserver中自带的pubs数据库Authors表进行测试.

  1):编写Authors.java，其每个对象对应于数据库中的一条记录

  package jdbc;public class Authors {   String  lname=null;   String fname=null;   String phone=null;   String address=null;    public String getAddress() { return address;    }    public String getFname() { return fname;    }    public String getLname() { return lname;    }    public String getPhone() { return phone;    }    public void setPhone(String phone) { this.phone = phone;    }    public void setLname(String lname) { this.lname = lname;    }    public void setFname(String fname) { this.fname = fname;    }    public void setAddress(String address) { this.address = address;    }}

  2):编写AuthorsQuery类

package jdbc;import java.sql.ResultSet;import java.sql.SQLException;import javax.sql.DataSource;import org.springframework.jdbc.object.MappingSqlQuery;import javax.sql.DataSource;

/** * <p>Title: 测试spring中的jdbc</p> * <p>Description: </p> * <p>Copyright: Copyright (c) 2004</p> * <p>Company: </p> * author hanker * version 1.0 */

public class AuthorsQuery extends MappingSqlQuery {

    public AuthorsQuery(DataSource ds) {   this.setDataSource(ds);   this.setSql("SELECT * FROM authors");   compile();    }

     protected Object mapRow(ResultSet rs, int rownum) throws SQLException {

   Authors po = new Authors();   po.setLname(rs.getString("au_lname"));   po.setFname(rs.getString("au_fname"));   po.setPhone(rs.getString("phone"));   po.setAddress(rs.getString("address"));   return po;     }

}

  3:写spring的配置文件

  <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<!--  - Application context definition for Petclinic on Hibernate. --><beans>       <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">  <property name="driverClassName"><value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value></property>  <property name="url"><value>jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=pubs;SelectMethod=Cursor</value></property>  <property name="username"><value>sa</value></property>  <property name="password"><value></value></property> </bean>

    <bean id="AuthorsQuery" class="jdbc.AuthorsQuery" singleton="false">     <constructor-arg index="0"><ref bean="dataSource"/></constructor-arg> </bean>  </beans>

  4:写junit进行测试

package jdbc;

import junit.framework.*;import org.springframework.context.ApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;import java.util.List;import java.util.Map;/** * <p>Title: 测试spring中的jdbc</p> * <p>Description: </p> * <p>Copyright: Copyright (c) 2004</p> * <p>Company: </p> * author hanker * version 1.0 */

public class TestAuthorsQuery extends TestCase {        ApplicationContext ctx=null; protected void setUp() throws Exception {      ctx   = new FileSystemXmlApplicationContext("D:\\work\\jpetstore\ rc\\jdbc\\Context-jdbc.xml"); } public void testQuery(){      System.out.println("[Test1....");      AuthorsQuery qry=(AuthorsQuery)ctx.getBean("AuthorsQuery");     List list = qry.execute();     if(list!=null&&list.size()>0){  for(int i=0;i<list.size();i++){      Authors author=(Authors)list.get(i);      StringBuffer buf=new StringBuffer();      buf.append(author.getLname())   .append("|")   .append(author.getFname())   .append("|")   .append(author.getPhone())   .append("|")   .append(author.getAddress());      System.out.println(buf.toString());                }            }

        }}

     5:编译运行，ok》是不是得到了你想要的结果

6:下面测试另处一种调jdbc的方法

   编写AuthorsQuery2.java文件    package jdbc;

   import java.util.List;   import org.springframework.context.ApplicationContextException;   import org.springframework.dao.DataAccessException;   import org.springframework.jdbc.core.SqlParameter;   import org.springframework.jdbc.core.support.JdbcDaoSupport;

/** * <p>Title: 测试spring中的jdbc</p> * <p>Description: </p> * <p>Copyright: Copyright (c) 2004</p> * <p>Company: </p> * author hanker * version 1.0 */

public class AuthorsQuery2 extends JdbcDaoSupport {    public AuthorsQuery2() {    }    public List query(String sql) throws DataAccessException {  return this.getJdbcTemplate().queryForList(sql);    }

}

7:配置,在上面加入下面几行：

       <bean id="AuthorsQuery2" class="jdbc.AuthorsQuery2">  <property name="dataSource"><ref local="dataSource"/></property> </bean>

8:写junit.   在TestAuthorsQuery中加入函数   public void testQuery2(){ System.out.println("[Test2....");   AuthorsQuery2 qry=(AuthorsQuery2)ctx.getBean("AuthorsQuery2");  List list = qry.query("SELECT * FROM authors");   if(list!=null&&list.size()>0){      for(int i=0;i<list.size();i++){   Map map=(Map)list.get(i);   StringBuffer buf=new StringBuffer();   buf.append(map.get("au_lname") )       .append("|")       .append(map.get("au_fname"))       .append("|")       .append(map.get("phone"))       .append("|")       .append(map.get("address"));   System.out.println(buf.toString());      }  }         }   

9:编译运行.以上代码经过测试，能够正常运行,
