I have used spring Shell 1.x. It provided provision for customise the banner. I am not trying to use Spring shell 2 and trying to do that same but i cannot finding the class.
Document also does not speak about it. Do any body know how to customise the same?
Banner is now the responsibility of Spring Boot, as explained here. Just drop a banner.txt file in your resources and it should be picked up

I am (still) kind of new to Spring Boot, and I trying to understand something with one of our Spring Boot applications, where, in the command line for running the application, we have a "-Dloader.main" parameter:
-Dloader.main=xxx.yyy.OurApplication org.springframework.boot.loader.PropertiesLauncher
I've been reading articles, etc., such as https://dzone.com/articles/configuring-a-main-class-in-spring-boot, but I am still not 100% clear about what that "-Dloader.main" does, in this case.
The 1st parameter, "xxx.yyy.OurApplication", is the Application that we (for example in Eclipse) normally do the "Run As", to start the application, so I think that the presence of the "org.springframework.boot.loader.PropertiesLauncher" as the 2nd parameter for the "-Dloader.main" allows us to specifically specify (sorry) which class is the main class by specifying it as the first parameter ("xxx.yyy.OurApplication"), INSTEAD OF whatever other main classes may be in the Spring Boot application.
Am I interpreting/understanding this correctly?
Thanks in advance,
Jim
P.S. I am sorry if the wording of my question may be somewhat convoluted :(...
I have been using the Spring Framework for about 4 years now, and now Spring Boot for the last couple of months. My Spring MVC applications are usually deployed on a Java EE container such as JBoss/WildFly or WebLogic. Doing so allows me to use JNDI for things like datasources or any other sensitive data that involve secrets/passwords. That makes my app "consume" that JNDI resource based on its name.
Now with Spring Boot and especially for self-contained microservices (embedded tomcat), that information is now stored within the application (application.properties and/or in Spring Java Config classes), so versioned in Git.
That makes that information a lot more exposed to other developers, which I'm not very comfortable with. I also don't like having those details show up in SonarQube and Jenkins (through workspaces).
Question is: Are there any best practices for this specific requirement?
* UPDATE *
I see some articles here and there about the use of Jasypt, but I wonder if it's still a valid library to use since the last stable release is dated from 2014.
Thank you
You could consider using a vault. Spring supports a few of them out of the box. You can find more information here http://projects.spring.io/spring-vault/.
If you have spring cloud in your stack, then it's very easy. Use encrypt the value and put it in the application properties. Follow the instruction mentioned here.
Other way is, set the values as environmental variables and using the environmental variables in the application properties. Instructions here
I am having a question regarding Spring ROO. Although this is not a good question to ask still as i am facing some issue.
I have created Spring ROO application using below link in Eclipse
http://docs.spring.io/spring-roo/reference/html/beginning.html
After putting some efforts i was able to see the application output as desired then a doubt came to mind that how i will print value from browser to Controller i.e. client to server side (System.out.println("")).
I have tried many solution but nothing seems to be working. So can some one tell me how will i do it.
Just to summarize the thing i want value from textfield etc in my .java file using above Spring ROO project.
Spring Roo just creates a Spring Web MVC application.
In your question I found that you need some architectural concepts about Spring Web MVC and Web applications that you must know to start developing application.
Try to read some tutorials and post (this looks good) before start to develop your application.
Good luck!

By using Spring 2.5,i have done a leave management project and it was adoptable.But in the reality,many of the controllers and other have been deprecated like "SimpleFormController",
"MultiController" ...so on in the other verion i.e 3.0.Iam little bit in secured ,does they reflect to my project like that.I know at some far,it is secured ,but not sure.suggestion are most welcome and your answers are more help full to me gain confidence.
No, in general spring controllers are not deprecated.
There is whole chapter about Controllers in Spring 4
I have completed setting up Spring Security using the roo shell as a guide and it has generated several views, amongst them is the login.jspx. I am trying to create a custom login form using Vaadin's Visual editor and Eclipse, how can i redirect the user to my login form and then use Spring Security to validate and authenticate the user as well as start a session management? I am really trying to avoid JSP since the rest of my application is using Vaadin as its Core Front-End
vaadin has some limitations on the login form.
Have a look at: https://vaadin.com/book/-/page/components.loginform.html so you will notice what I mean.
You can also have a look at the vaadin wiki (https://vaadin.com/wiki). There are several articles on your topic. You may find your solution there :)
kind regards
