eclipse 怎么与PL/SQL进行连接用ssm
1、运行Eclipse，新建一个Java Project 名为 Test
2、右单击src，依次选择 Build Path → Configure Build Path，在打开的窗口的右边选择 Libraries 标签，然后单击 Add External JARs，找到 sqljdbc4.jar 文件并打开，然后单击 OK 完成构建路径的配置。
3、在Test中新建包pkg，在pkg中新建一个类Main，在其中输入代码如下：
package pkg
import java.sql.*
public class Main {
public static void main(String [] args)
{
String driverName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
String dbURL="jdbc:sqlserver://localhost:1433DatabaseName=你的数据库名"
String userName="填写你的用户名，我的是sa"
String userPwd="填写你的密码"
try
{
Class.forName(driverName)
Connection dbConn=DriverManager.getConnection(dbURL,userName,userPwd)
System.out.println("连接数据库成功")
}
catch(Exception e)
{
e.printStackTrace()
System.out.print("连接失败")
}
}
}
5、点击右键，选择 run as —> Java Application, 控制台出现下图则连接成功！
ssm框架怎么使用事务和存储过程
SSM（Spring SpringMVC MyBatis）框架集由Spring、SpringMVC、MyBatis三源框架整合作数据源较简单web项目框架
其spring轻量级控制反转（IoC）面向切面（AOP）容器框架
SpringMVC离控制器、模型象、派器及处理程序象角色种离让更容易进行定制
MyBatis支持普通SQL查询存储程高级映射优秀持久层框架
