Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 1 00:00:00,662 --> 00:00:02,891 All righty, so let's go ahead and move in 2 2 00:00:02,891 --> 00:00:04,963 and let's walk through this development process. 3 3 00:00:04,963 --> 00:00:06,930 So the first step is that we're actually gonna 4 4 00:00:06,930 --> 00:00:11,097 enable component scanning in our Spring configuration file. 5 5 00:00:14,215 --> 00:00:16,272 All right, so moving into our Eclipse project 6 6 00:00:16,272 --> 00:00:19,028 that we just created, that spring-demo-annotation, 7 7 00:00:19,028 --> 00:00:22,860 line:15% what I wanna do is actually copy over the config file 8 8 00:00:22,860 --> 00:00:25,027 line:15% from our previous project. 9 9 00:00:26,334 --> 00:00:29,023 line:15% So what I wanna do is actually move into my 10 10 00:00:29,023 --> 00:00:32,278 line:15% spring-demo-one project, and I'm actually gonna copy 11 11 00:00:32,278 --> 00:00:35,718 line:15% the applicationContext.xml and I'll move it to my new one. 12 12 00:00:35,718 --> 00:00:39,388 line:15% So in spring-demo-one, selection applicationContext.xml, 13 13 00:00:39,388 --> 00:00:42,138 line:15% do a right-click and choose Copy. 14 14 00:00:44,653 --> 00:00:47,394 line:15% And now let's move back to our spring-demo-annotation, 15 15 00:00:47,394 --> 00:00:48,662 line:15% that's the one that we just created, 16 16 00:00:48,662 --> 00:00:51,972 line:15% and let's simply move to the source directory, 17 17 00:00:51,972 --> 00:00:55,500 line:15% and then we do a right-click and choose Paste. 18 18 00:00:55,500 --> 00:00:56,333 line:15% And it's important that you paste it 19 19 00:00:56,333 --> 00:00:58,408 line:15% into the source directory. 20 20 00:00:58,408 --> 00:01:01,075 line:15% So right-click and choose Paste. 21 21 00:01:02,907 --> 00:01:04,518 Okay, great, now if we expand the source directory 22 22 00:01:04,518 --> 00:01:06,864 for spring-demo-annotations, we should see this new 23 23 00:01:06,864 --> 00:01:10,905 config file here, applicationContext.xml. 24 24 00:01:10,905 --> 00:01:12,800 Let's go ahead and open this file up for a second 25 25 00:01:12,800 --> 00:01:15,550 and just take a quick look at it. 26 26 00:01:17,501 --> 00:01:19,642 I'll just expand the window here. 27 27 00:01:19,642 --> 00:01:22,327 Now, what I actually wanna do is clean out this file, 28 28 00:01:22,327 --> 00:01:24,930 line:15% so I wanna remove all the bean entries in this file, 29 29 00:01:24,930 --> 00:01:26,607 line:15% so simply highlight everything there 30 30 00:01:26,607 --> 00:01:28,016 line:15% for all the bean entries, 31 31 00:01:28,016 --> 00:01:31,349 line:15% I'll do a right-click and choose Delete. 32 32 00:01:32,639 --> 00:01:34,773 So at this point we should have everything deleted 33 33 00:01:34,773 --> 00:01:36,844 from this file, we should only have what I have here, 34 34 00:01:36,844 --> 00:01:38,566 on the screen, so kinda use this as a checkpoint 35 35 00:01:38,566 --> 00:01:41,816 to make sure your file looks like mine. 36 36 00:01:44,480 --> 00:01:45,989 All right, and also I like to clean up, 37 37 00:01:45,989 --> 00:01:48,928 so let's go ahead and close that previous project we had, 38 38 00:01:48,928 --> 00:01:50,827 spring-demo-one, that's the old one, 39 39 00:01:50,827 --> 00:01:53,216 so let's just simply do a right-click and choose Close 40 40 00:01:53,216 --> 00:01:54,549 on that project. 41 41 00:02:00,365 --> 00:02:02,204 Because I like to kinda keep things simple, 42 42 00:02:02,204 --> 00:02:03,961 make sure I only have one project at a time, 43 43 00:02:03,961 --> 00:02:06,192 line:15% make sure I'm only editing a given file at a time, 44 44 00:02:06,192 --> 00:02:09,149 line:15% because you get mixed up with too much stuff. 45 45 00:02:09,149 --> 00:02:12,043 line:15% So step one is that we're gonna enable component scanning 46 46 00:02:12,043 --> 00:02:13,611 line:15% in our Spring config file. 47 47 00:02:13,611 --> 00:02:16,219 line:15% So let's go into our applicationContext.xml, 48 48 00:02:16,219 --> 00:02:17,726 let's move down to line 10, 49 49 00:02:17,726 --> 00:02:20,535 and I'll add a quick little comment here, 50 50 00:02:20,535 --> 00:02:22,394 just to kinda keep myself on track. 51 51 00:02:22,394 --> 00:02:26,561 So I'm gonna add an entry to enable component scanning. 52 52 00:02:30,389 --> 00:02:33,109 And then I'll actually add the code here on line 12, 53 53 00:02:33,109 --> 00:02:37,625 so I'll say context: and I'll choose component-scan, 54 54 00:02:37,625 --> 00:02:42,624 that's the same thing we saw on the slides earlier, 55 55 00:02:42,624 --> 00:02:44,619 and then I'll give the actual base package name, 56 56 00:02:44,619 --> 00:02:47,950 so I'll call it com.Luv2code.springdemo. 57 57 00:02:47,950 --> 00:02:49,813 And I'll just put a slash here at the end, 58 58 00:02:49,813 --> 00:02:51,692 just to get that taken care of. 59 59 00:02:51,692 --> 00:02:52,775 So that's it really. 60 60 00:02:52,775 --> 00:02:55,121 So context:component-scan, we give the base package 61 61 00:02:55,121 --> 00:02:56,957 and we give the actual name of our package 62 62 00:02:56,957 --> 00:02:59,322 of where we're gonna place code. 63 63 00:02:59,322 --> 00:03:01,308 And so again, Spring will do all the scanning, 64 64 00:03:01,308 --> 00:03:02,769 look for those annotations, 65 65 00:03:02,769 --> 00:03:06,815 and then register those beans automatically. 66 66 00:03:06,815 --> 00:03:08,943 line:15% All right, now while I'm here let's go ahead and create 67 67 00:03:08,943 --> 00:03:11,582 line:15% the package since we remember the package name, 68 68 00:03:11,582 --> 00:03:13,386 line:15% let's go ahead and create it real quick. 69 69 00:03:13,386 --> 00:03:14,747 line:15% So in our source directory, 70 70 00:03:14,747 --> 00:03:17,948 line:15% let's simply do a right-click, choose New, 71 71 00:03:17,948 --> 00:03:20,448 line:15% and then we'll choose Package. 72 72 00:03:22,244 --> 00:03:24,037 And I'll give the actual package name, 73 73 00:03:24,037 --> 00:03:27,706 it's com.Luv2code.springdemo, you have to make sure 74 74 00:03:27,706 --> 00:03:30,106 it's the exact same package name that you reference 75 75 00:03:30,106 --> 00:03:32,564 in the Spring config file, 'cause this is where 76 76 00:03:32,564 --> 00:03:36,397 Spring's gonna scan, looking for Spring beans. 77 77 00:03:37,326 --> 00:03:39,178 So I'll hit Finish, and there we go, 78 78 00:03:39,178 --> 00:03:41,837 we have this new package, com.Luv2code.springdemo, 79 79 00:03:41,837 --> 00:03:44,186 I'll just look at my config file and make sure 80 80 00:03:44,186 --> 00:03:46,910 those two names are the same. 81 81 00:03:46,910 --> 00:03:47,956 So this looks good. 82 82 00:03:47,956 --> 00:03:50,345 So we have step one completed so far, 83 83 00:03:50,345 --> 00:03:52,259 so we have the component scanning in place. 84 84 00:03:52,259 --> 00:03:54,612 In the following video we'll actually start writing code, 85 85 00:03:54,612 --> 00:03:56,985 and we'll follow those two additional steps 86 86 00:03:56,985 --> 00:03:59,547 required for this configuration process. 87 87 00:03:59,547 --> 00:04:01,630 So I'll see you in a bit. 8062
