3. StudentDao.java

package com.jd.dao;import java.util.List;public interface StudentDao<T> {public void saveStudent();public T queryStudent(int id);public List<T> queryStudentList();
}

4. StudentDaoImpl.java

package com.jd.dao.impl;import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.List;import javax.annotation.Resource;import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;import com.jd.dao.StudentDao;
import com.jd.vo.Student;public class StudentDaoImpl<T> implements StudentDao<T>{//private DataSource dataSource;private JdbcTemplate template;/*public DataSource getDataSource() {return dataSource;}*//*** 注入dataSource* @param dataSource*//*@Resourcepublic void setDataSource(DataSource dataSource) {this.dataSource = dataSource;this.template = new JdbcTemplate(dataSource);}*/public JdbcTemplate getTemplate() {return template;}/*** 注解注入* @param template*/@Resourcepublic void setTemplate(JdbcTemplate template) {this.template = template;}public void saveStudent() {/*try {Connection conn = dataSource.getConnection();Student s = new Student();s.setId(4);s.setName("张四");String sql = "insert into student values(?,?)";PreparedStatement state = conn.prepareStatement(sql);state.setInt(1, s.getId());state.setString(2, s.getName());state.execute();System.out.println("保存学生成功");} catch (SQLException e) {e.printStackTrace();}*/Student s = new Student();s.setId(7);s.setName("张七");template.update("insert into student values(?,?)", new Object[]{s.getId(),s.getName()}, new int[]{java.sql.Types.INTEGER,java.sql.Types.VARCHAR});System.out.println("保存学生成功");}@SuppressWarnings({ "rawtypes", "unchecked" })public T queryStudent(int id) {//回调函数RowMapper rowMapper = new RowMapper(){public Object mapRow(ResultSet rs, int rowNum) throws SQLException {Student stu = new Student();stu.setId(rs.getInt(1));stu.setName(rs.getString(2));return stu;}};System.out.println("查询学生id：" + id);    return (T)template.queryForObject("select * from Student where id=?", new Object[]{id}, new int[]{java.sql.Types.INTEGER}, rowMapper);}@SuppressWarnings({ "unchecked", "rawtypes" })public List<T> queryStudentList() {RowMapper rowMapper = new RowMapper(){public Object mapRow(ResultSet rs, int rowNum) throws SQLException {Student stu = new Student();stu.setId(rs.getInt(1));stu.setName(rs.getString(2));return stu;}};System.out.println("查询所有学生");    return (List<T>)template.query("select * from Student", null, null, rowMapper);}}

JdbcTemplate主要提供以下五类方法：

• execute方法：可以用于执行任何SQL语句，一般用于执行DDL语句；

• update方法及batchUpdate方法：update方法用于执行新增、修改、删除等语句；batchUpdate方法用于执行批处理相关语句；

• query方法及queryForXXX方法：用于执行查询相关语句；

• call方法：用于执行存储过程、函数相关语句。

  5. 测试类

• import java.util.List;import junit.framework.TestCase;import org.springframework.context.ApplicationContext;
  import org.springframework.context.support.ClassPathXmlApplicationContext;import com.jd.dao.StudentDao;
  import com.jd.vo.Student;public class TestSpringJdbcTemplate extends TestCase {public void testSpringJdbc(){ApplicationContext ctx = new ClassPathXmlApplicationContext("application.xml");StudentDao dao =  (StudentDao)ctx.getBean("studentDao");dao.saveStudent();Student stu = (Student) dao.queryStudent(5);System.out.println("学号：" + stu.getId() + ", 姓名：" + stu.getName());List<Student> students = dao.queryStudentList();for(Student stu:students){System.out.println("学号：" + stu.getId() + ", 姓名：" + stu.getName());}}
  }
