Third, create a client
Eclipse quickly picks EJB - 3. Design a one-to-one two-way relationship CMR (1)
Eclipse quickly EJB - 3. One-to-one two-way relationship CMR (2)
1. Right-click the SRC folder -> New-> Lomboz EJB Test Client Wizard:
2. Modify the generated cmpclient2.java, call the method in the userManagementBean.
2. Two static methods are established in vitro in TestBean () methods, simplifying code calls.
// create a user public static void createUsers (UserManagement userMgmt) throws RemoteException, CreateException {System.out.println ( "UserInfo added to the data in the table"); userMgmt.addUser ( "wangyi@aaa.com", "password 1", "Wang Yi", "Engineering", "111-1212", 22, 2000); usermgmt.adduser ("wanger@bbb.net", "password 2", "Wang 2", "marketing", "222-1213 ", 40, 4000); usermgmt.adduser (" zhangsan@bbb.ccc "," password 3 "," Zhang San "," IT "," 1688888 ", 32, 2800); usermgmt.adduser (" Lisi @ BBB .ccc "," password 4 "," Li Si "," Sales "," 1288888 ", 28, 2700); usermgmt.adduser (" zhu@bbb.eee "," password 5 "," Zhu Wang 5 ", "Sales", "1588888", 38, 4500); usermgmt.adduser ("javamxj@yahoo.com.cn", "Sharing Java Happy", "MXJ", "IT", "1788888", 26, 2900); } // Output ArrayList Private Static Void PrintList (ArrayList List) {ipiTerrator I = List.ITerator (); while (I.hasNext ()) {Object Details = (Object) i.next (); System.out.Println Details.toString ());} system.out.println ("");
3. Then, change the MyBean in the TestBean () method to the usermgmt, add data and display data to the table. As described below, the slope is the change portion.
public
Void testbean () {
Try {
Javamxj.ejb.cmp.userManagement
Usermgmt = gethome (). CREATE ();
CreateUsers (usermgmt); system.out.println ("Show All User"); PrintList (usermgmt.getusers ()); Run the program, the console output is as follows:
4. Comment "CREATEUSERS (usermgmt);" to invoke password verification and change the user's name.
// CREATEUSERS (usermgmt);
System.out.println (
"Show all users");
PrintList (usermgmt.getusers ());
Boolean login = false; login = usermgmt.verifypassword ("javamxj@yahoo.com.cn", "Share Java Happy"); System.Out.println ("Password Verification:" login;
System.out.println ("Changing the name of the user javamxj@yahoo.com.cn"); usermgmt.changeename ("javamxj@yahoo.com.cn", "hello");
If you run the program, you will find that JavaMxj's name has been changed to hello:
5. Continue to call the method of using the user:
System.out.println ("User using EJB.Finder"); PrintList (usermgmt.getuserbyage1 (30)); system.out.println ("User uses EJB.SELECT output age greater than 30 users"); PrintList (Usermgmt.getuserbyage2); Output:
6. Continue to call the method of outputting the user via the valueObject:
System.out.println ("Output User Information via ValueObject:"); userinfovalue [] users = usermgmt.getusersInfo (); for (int index = 0; index Output: 7. Continue to call the user's way to query the user: SYSTEM .out.println ("Output of the user"); PrintList (usermgmt.getusersbyname); system.out.println ("Output Name User User"); PrintList (usermgmt.getusersbyname ("% Wang%")); Output: 8. Delete a user, since the tagged tag has been set, although the method of call is the method in the userbean, but still deletes the data related to the userInfobean. / / Delete a user usermgmt.removeuser (zhu@bbb.eee); Viewing the data sheet will find "zhu@bbb.eee" data from the use of "zhu@bb.eee" in use at the same, and userinfotable.
