WEBVTT 1 00:00:01.280 --> 00:00:03.460 So let's look at the release timeline. 2 00:00:03.460 --> 00:00:06.710 So here's the timeline for J2EE, or Java EE. 3 00:00:06.710 --> 00:00:08.800 Started off in '99, moved all the way down 4 00:00:08.800 --> 00:00:12.520 to our current state here of Java EE 7 in 2013, 5 00:00:12.520 --> 00:00:17.520 Java EE 8 which is coming real soon, 2016/2017. 6 00:00:17.620 --> 00:00:22.620 And then, basically around the 2001/2003 timeframe, 7 00:00:23.030 --> 00:00:24.680 that's when everyone was just kind of fed 8 00:00:24.680 --> 00:00:26.060 up with Enterprise JavaBeans 9 00:00:26.060 --> 00:00:28.240 and just didn't want to do it anymore. 10 00:00:28.240 --> 00:00:31.910 So that's when Spring 1.0 came out, around 2004 11 00:00:31.910 --> 00:00:34.100 because prior to that, EJBs were just horrible 12 00:00:34.100 --> 00:00:35.650 and no-one wanted to use it anymore. 13 00:00:35.650 --> 00:00:36.650 So you came out with Spring, 14 00:00:36.650 --> 00:00:39.275 Spring 1, Spring 2, Spring 3, and so on. 15 00:00:39.275 --> 00:00:42.410 One thing that's interesting here is that the folks 16 00:00:42.410 --> 00:00:45.180 at Sun Microsystems at the time before they were acquired 17 00:00:45.180 --> 00:00:48.856 by Oracle, at the time they realized, "Whoa, 18 00:00:48.856 --> 00:00:51.617 "What's this Spring thing and whoa, why is everyone 19 00:00:51.617 --> 00:00:55.020 "moving towards it and why's everyone using it now?" 20 00:00:55.020 --> 00:00:56.630 Mainly because of EJB. 21 00:00:56.630 --> 00:00:58.140 Folks were tired of EJB. 22 00:00:58.140 --> 00:01:00.750 So the folks at Sun actually went back and kind of, 23 00:01:00.750 --> 00:01:05.320 re-engineered or re-wrote EJB to make it simpler 24 00:01:05.320 --> 00:01:07.300 and make it easier to use. 25 00:01:07.300 --> 00:01:11.810 So that came around the 2006/2009 timeframe. 26 00:01:11.810 --> 00:01:15.630 So effectively, by the time you made it to Java EE 6, 27 00:01:15.630 --> 00:01:17.010 they'd actually cleaned up the problems 28 00:01:17.010 --> 00:01:19.110 that they had with EJB and actually made it a little 29 00:01:19.110 --> 00:01:20.250 bit easier to use. 30 00:01:20.250 --> 00:01:21.690 So effectively, the same thing as Spring. 31 00:01:21.690 --> 00:01:23.050 It has the Inversion of Control, 32 00:01:23.050 --> 00:01:24.460 it has Dependency Injection. 33 00:01:24.460 --> 00:01:26.885 So current day here, Java EE 7, 34 00:01:26.885 --> 00:01:31.520 you can really do everything that Spring can do, 35 00:01:31.520 --> 00:01:32.610 with Java EE 7. 36 00:01:32.610 --> 00:01:34.310 So you can do all the annotations, 37 00:01:34.310 --> 00:01:38.770 no XML stuff, just like Spring and it's really easy 38 00:01:38.770 --> 00:01:40.010 to do now. 39 00:01:40.010 --> 00:01:43.200 The only problem though is that they were just a little bit 40 00:01:43.200 --> 00:01:47.040 too late and unfortunately, EJB just kind of has a bad name 41 00:01:47.040 --> 00:01:52.040 or a bad reputation and also, Spring has huge momentum, 42 00:01:53.450 --> 00:01:54.760 huge market share. 43 00:01:54.760 --> 00:01:56.430 So there's a lot of Apps that are already 44 00:01:56.430 --> 00:01:58.071 out there written using Spring 45 00:01:58.071 --> 00:02:00.470 and there's a lot more that are going to be created 46 00:02:00.470 --> 00:02:01.303 using Spring. 47 00:02:01.303 --> 00:02:03.407 So that's why Spring is very popular now 48 00:02:03.407 --> 00:02:05.410 and kind of why it's still popular. 49 00:02:05.410 --> 00:02:06.880 It's a lightweight framework, it's simple, 50 00:02:06.880 --> 00:02:09.950 easy to use and a lot of developers like it. 51 00:02:09.950 --> 00:02:13.360 And they basically ran away from the old days of EJB 52 00:02:13.360 --> 00:02:14.990 and J2EE. 53 00:02:14.990 --> 00:02:16.630 So that's kind of the big spiel. 54 00:02:16.630 --> 00:02:19.170 But really now, if you put both technologies 55 00:02:19.170 --> 00:02:22.680 side by side, you can do the same with either one. 56 00:02:22.680 --> 00:02:24.510 But again, the whole reputation thing 57 00:02:24.510 --> 00:02:26.103 and also, the momentum thing. 58 00:02:27.110 --> 00:02:29.743 So as I mentioned, Spring is very popular, 59 00:02:30.792 --> 00:02:31.810 it has a lot of market share, 60 00:02:31.810 --> 00:02:33.590 it has a lot of projects written in it. 61 00:02:33.590 --> 00:02:35.990 And Spring is still in demand. 62 00:02:35.990 --> 00:02:38.540 It's the most sought after Java skillset by employers 63 00:02:38.540 --> 00:02:39.680 and recruiters. 64 00:02:39.680 --> 00:02:42.500 And, this is really funny, I actually have a friend 65 00:02:42.500 --> 00:02:44.950 of mine, I used to work with him on a previous job, 66 00:02:44.950 --> 00:02:47.300 he's actually in the process now of interviewing 67 00:02:47.300 --> 00:02:50.008 for a new position and I spoke with him last week. 68 00:02:50.008 --> 00:02:51.757 He sent me a message and he said, 69 00:02:51.757 --> 00:02:52.590 "Hey." 70 00:02:52.590 --> 00:02:55.077 and this is his actual text message, 71 00:02:55.077 --> 00:02:57.797 "Man, everybody and their mama keeps asking 72 00:02:57.797 --> 00:02:58.997 "me about Spring. 73 00:02:58.997 --> 00:03:01.620 "You better get started on that Udemy course lol." 74 00:03:01.620 --> 00:03:04.220 And again, this is some American slang here, 75 00:03:04.220 --> 00:03:05.380 everybody and their mama meaning, 76 00:03:05.380 --> 00:03:07.940 basically every recruiter he's talked to 77 00:03:07.940 --> 00:03:09.942 and every employer he's interviewed with, 78 00:03:09.942 --> 00:03:12.900 they are asking him a good deal about Spring. 79 00:03:12.900 --> 00:03:15.410 So again, very good skillset for you to have 80 00:03:15.410 --> 00:03:16.363 on your resume. 81 00:03:17.560 --> 00:03:19.320 So you may have the question, what should you do? 82 00:03:19.320 --> 00:03:20.620 Should you learn Spring? 83 00:03:20.620 --> 00:03:22.410 Or should you learn Java EE? 84 00:03:22.410 --> 00:03:25.210 And my answer's that you should learn both. 85 00:03:25.210 --> 00:03:26.043 Right? 86 00:03:26.043 --> 00:03:27.900 The reason is because now you'll be flexible 87 00:03:27.900 --> 00:03:30.250 in the job market and if you go on a job interview, 88 00:03:30.250 --> 00:03:32.350 or you join a new project team, 89 00:03:32.350 --> 00:03:34.540 you'll be able to handle either one of them. 90 00:03:34.540 --> 00:03:38.040 And a really cool thing about it is that a lot of the skills 91 00:03:38.040 --> 00:03:41.580 are interchangeable, especially now since Spring and Java EE 92 00:03:41.580 --> 00:03:44.660 are kind of in line, or in sync with their feature set. 93 00:03:44.660 --> 00:03:48.306 So once you learn how to do MVC in one framework 94 00:03:48.306 --> 00:03:50.810 then learning how to do MVC in another framework 95 00:03:50.810 --> 00:03:51.990 is similar. 96 00:03:51.990 --> 00:03:54.516 Implementing it is very similar between Java EE 97 00:03:54.516 --> 00:03:55.940 and also with Spring. 98 00:03:55.940 --> 00:03:59.470 So I'd say learn both of them and you'll learn Spring 99 00:03:59.470 --> 00:04:00.900 in this class for sure, 100 00:04:00.900 --> 00:04:02.810 I'll show you how to use Spring MVC, 101 00:04:02.810 --> 00:04:05.320 and also I'll show you how to hook all this into a database 102 00:04:05.320 --> 00:04:06.560 using Hibernate. 103 00:04:06.560 --> 00:04:08.120 And then I have a lot of other courses 104 00:04:08.120 --> 00:04:09.970 that cover some of the Java EE technologies 105 00:04:09.970 --> 00:04:12.680 like JSP, Servelet and JSF, if you wanted 106 00:04:12.680 --> 00:04:14.803 to go and check out some of my other courses 107 00:04:14.803 --> 00:04:17.480 on learning those other Java EE technologies. 108 00:04:17.480 --> 00:04:19.098 Anyway, I say learn them both, 109 00:04:19.098 --> 00:04:21.050 you're a smart person, right. 110 00:04:21.050 --> 00:04:22.930 And it's easy to pick up on them once you learn 111 00:04:22.930 --> 00:04:26.680 one technology it's easy to jump into the next technology. 112 00:04:26.680 --> 00:04:28.650 So anyways, I'd recommend picking 113 00:04:28.650 --> 00:04:30.150 up both of those technologies. 114 00:04:31.970 --> 00:04:34.080 So this kind of wraps up the video. 115 00:04:34.080 --> 00:04:36.630 I wanted to give you some motivation on why Spring. 116 00:04:36.630 --> 00:04:38.440 Give you a little bit of background on the history 117 00:04:38.440 --> 00:04:42.350 of J2EE, and kind of where Spring came into play. 118 00:04:42.350 --> 00:04:43.960 In the following videos I'll give you 119 00:04:43.960 --> 00:04:45.780 a more formal discussion of Spring 120 00:04:45.780 --> 00:04:48.250 as far as the various components of the framework 121 00:04:48.250 --> 00:04:50.580 and then of course, we're going to start diving 122 00:04:50.580 --> 00:04:53.100 in to writing code using Spring. 123 00:04:53.100 --> 00:04:55.060 So we have a lot of good things coming up here, 124 00:04:55.060 --> 00:04:56.610 I'll see you in the next video.
