三、创建客户端

Eclipse快速上手EJB -- 3. 设计一对一的双向关系的CMR(1)

Eclipse快速上手EJB -- 3. 一对一的双向关系的CMR(2)

1. 右击 src 文件夹 ->新建 ->Lomboz EJB Test Client Wizard:

2. 修改生成的 CMPClient2.java,调用UserManagementBean中的方法。

2. 先在testBean()方法体外建立两个static方法,简化代码调用。

// 创建用户

public static void createUsers(UserManagement userMgmt)

throws RemoteException, CreateException {

System.out.println("向UserInfo表中添加数据");

userMgmt.addUser("wangyi@aaa.com", "密码1", "王一",

"Engineering", "111-1212", 22, 2000);

userMgmt.addUser("wanger@bbb.net", "密码2", "王二",

"Marketing", "222-1213",40, 4000);

userMgmt.addUser("zhangsan@bbb.ccc", "密码3", "张三",

"IT", "1688888", 32, 2800);

userMgmt.addUser("lisi@bbb.ccc", "密码4", "李四",

"Sales", "1288888", 28, 2700);

userMgmt.addUser("zhu@bbb.eee", "密码5", "朱王五",

"Sales", "1588888", 38, 4500);

userMgmt.addUser("javamxj@yahoo.com.cn", "分享Java快乐", "MXJ",

"IT", "1788888", 26, 2900);

}

// 输出ArrayList

private static void printList(ArrayList list) {

Iterator i = list.iterator();

while (i.hasNext()) {

Object details = (Object) i.next();

System.out.println(details.toString());

}

System.out.println("");

}

3. 然后,将testBean()方法体内的 myBean 改成 userMgmt,再向表中添加数据及显示数据。如下,斜体的即是改动部分。

public void testBean() {

try {

javamxj.ejb.cmp.UserManagement userMgmt = getHome().create();

createUsers(userMgmt);

System.out.println("显示所有用户");

printList(userMgmt.getUsers());

运行程序,则控制台输出如下:

4. 将“createUsers(userMgmt);”语句注释掉,调用密码验证及改变用户姓名的方法。

//createUsers(userMgmt);

System.out.println("显示所有用户");

printList(userMgmt.getUsers());

boolean login = false;

login = userMgmt.verifyPassword("javamxj@yahoo.com.cn", "分享Java快乐");

System.out.println("密码验证: " + login);

System.out.println("改变用户javamxj@yahoo.com.cn的名字");

userMgmt.changeName("javamxj@yahoo.com.cn","Hello");

运行程序,则会发现 javamxj 的姓名已被更改为 Hello:

5. 继续调用按年龄查询用户的方法:

System.out.println("采用 ejb.finder 输出大于30的用户");

printList(userMgmt.getUserByAge1(30));

System.out.println("采用 ejb.select 输出年龄大于30的用户");

printList(userMgmt.getUserByAge2(30));

输出:

6.继续调用通过ValueObject输出用户的方法:

System.out.println("通过 ValueObject 输出用户信息:");

UserInfoValue[] users = userMgmt.getUsersInfo();

for (int index = 0; index < users.length; index++) {

UserInfoValue user = users[index];

System.out.println("用户 " + user.getEmail() + " 的年龄:"+ user.getAge());

}

输出:

7. 继续调用通过姓名查询用户的方法:

System.out.println("输出姓王的用户");

printList(userMgmt.getUsersByName("王%"));

System.out.println("输出姓名中含有王字的用户");

printList(userMgmt.getUsersByName("%王%"));

输出:

8. 删除一个用户,由于已经设置了级联删除的标记,所以虽然调用的方法是UserBean中的方法,但仍然会同时删除UserInfoBean中相关的数据。

// 删除一个用户

userMgmt.removeUser(zhu@bbb.eee);

查看数据表,会发现已经同时删除了usertable和userinfotable中关于的“zhu@bbb.eee”数据。

好了,这个算是讲完了。欲知后事如何,且听下回分解。
