Finally did the Spring Core exam 4.3

Long time - no see :-) The last post has been ~6 month ago -  I was very busy with different topics. Today I'd like to start again and promise post more regulary (...). Perhaps you do remember that I trained for the Spring Core Developer 4.3 exam. 3 weeks ago I finally did the test and passed it. I'd like to share a little bit here. The first thing is that the exam was done with  examslocal . So you schedule an appointment and the test happens online while you are watched via your webcam. That was a first for me and quite strange. I had to remove everything from my desk and had to show the room to the examiner (a little hard with a laptop and lan cable -  I lost the connection twice...).  On one question I started to read the question out loud, I do this sometimes to get more concentrated. Suddenly the chat popped up and the examiner told me to stop that. A colleague of mine did the same test and was told to look onto his screen and not somewhere else. I understand the neces

Spring Cloud Netflix - Hystrix and properties

My Spring certification preparation are on hold because some trainings are ahead I have to prepare for. One will be Spring Boot withSpring Cloud. I have been working with Spring Boot for 4 years now and am a huge fanboy. Spring Cloud is something I looked into and we use Hystrix in a project but I have been scratching the surface mostly. One thing I learned in my preparation I want to share with you because it took me some hours since I finally found my mistake. On the mentioned project we use Hystrix like it's shown on the Javanica page: @HystrixCommand ( commandProperties = { @HystrixProperty ( name = " execution.isolation.thread.timeoutInMilliseconds " , value = " 500 " ) }) public User getUserById( String id) { return userResource . getUserById(id); } Now I wanted to configure some default properties in my application.yaml. I took the values like the above "execution.isolation.thread.timeoutInM

Another Spring Mock Exam Simulator

Hello again, after finishing the SpringDoc ePub I found another Spring Mock Exam simulator: SpringMockExams . You get 4 tests with 50 questions each. This is one test less than by iTestJava . I already did the first 3 tests and have to say that I like the questions better and that the simulator look much nicer. There aren't too much xml-questions like on iTestJava, too. On the other hand I was very surprised that they do not have a test history. So you aren't able to look at your test results later on. That's currently the biggest issue I have with them. What I learned is that I have to take a closer look at Spring Security. I already downloaded the ePub (that is really a nice feature of the Spring work) and will read it next week. After that I think I have to dive into the test center question because it seems for the 4.3 exam there's a different provider than PearsonVUE. More on that next week. Bye, Michael

Java-Workshops am Regionalzentrum Hamburg der FernUniversität

More on Spring certification

I'm still busy reading the official Spring doc as ePub. Reached 42% this morning. I found a mock exam, too. The site iTestJava  offers 250 questions (5 tests a 50 questions) for the 4.3 certification. After doing the 5 example questions, I was a bit disappointed because the doc reference was 4.0.9 even for the 4.3 cert. So I wrote to them about this and they answered they'd have some 4.3 questions in the 4.3 package as well. After agreeing on a discount I bought the package. The test system itself does not look very nice and for example it is not possible to go back a question until one has reached the last questions. There are many questions on xml configuration. I think way too much for the 4.3 cert but I can't say that for sure until I actually do the exam. Overall I did not too good on the exams, I think around 50-60%. That's a good sign, it means I learned new things. The future will tell whether this knowledge is helpful for the exam. I have another mock exam

Finally another certification

I'm kind of a certification addict. I did most of the Sun/Oracle Java certs and update them every time it's possible. But for some time now there wasn't anything to do. I even thought about doing the JSF cert just to do something... But some weeks ago Pivotal blog-ed that they would offer Spring certification without enrolling for a course . Fantastic news because I don't want to pay for a course and I'm a big fan of the Spring Framework for years now. So, some days ago I started preparing by downloading the ePub of the current Spring docs  and loading it up onto my Kobo. A week later 25% of it have been read :-) What I probably should mention is that I do certifications not only to have them but also to learn new things. With the Java certifications (most of all the Programmer I think) I did learn much. You have to dive into things you need not use for every day work (but perhaps later). E.G. doing the OCJP 7 I learned of the fantastic nio2 way to do file work.

Auch im Sommer-Semester 2017 wieder Java-Kurse am Regionalzentrum Hamburg der FeU
