就是在spring中，对mysql数据库进行增删改查的样例，很easy。
文件结构
maven的pom.xml文件，里面用到的几个很重要的jar包都有

操作类
package nx.database;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import javax.sql.DataSource;
public class StudentsDaoImpl implements StudentsDao{
private DataSource dataSource;
public DataSource getDataSource() {
return dataSource;
}
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
public void saveStudents() {
Connection conn=null;
PreparedStatement stmt=null;
try {
conn=dataSource.getConnection();
stmt=conn.prepareStatement("INSERT INTO `data`.`student` (`id`, `name`) VALUES (NULL, 'jiang');");
stmt.execute();
stmt.close();
conn.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("保存学生信息成功。");
}
}
beans.xml(注意，数据库的password替换成你自己的password)

測试类
package nx.database;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext ctx=new ClassPathXmlApplicationContext("nx/database/beans.xml");
StudentsDaoImpl userImpl=(StudentsDaoImpl)ctx.getBean("userImpl");
userImpl.saveStudents();
}
}
在完毕后，查看数据库，发现已经有了数据
