            Cron jobs for next Sunday of first Friday of every quarter of the year
            Asked 2021-Jan-25 at 19:05

            I am using java spring boot. I need to fetch data which updates as "Data sets are updated quarterly (March, June, September, December), typically on the first Friday of the month"

            And I want to run Cron job on next Sunday (want to keep one entire saturday as buffer) after that. What will be Crone expression for this condition?

            Special cases we'll need to address: When Sunday is day #1 or day #2 of the month. By limiting Sundays to days in the range 3-9, we're safe. When Sunday is day #3 or greater, we can know for sure that there is a preceding Friday in current month.

            Create a new Vaadin Flow 16/17 project using plain Java Servlets without Spring/CDI
            Asked 2020-Aug-23 at 03:26

            The starter page for Vaadin Flow has changed. That page now offers new projects configured only for Spring Boot. The previous version of this page offered an option for "Plain Java Servlet" as well as Spring/CDI.

            The Vaadin documentation suggests using a Maven archetype manually. But the Maven repositories for com.vaadin… appear to be aimed at Vaadin 8 and earlier, with none for Vaadin 10 and later.

            The Vaadin page on learning Maven shows an example using viritin-vaadin-flow-archetype as an archetype. But Viritin is a third-party project, and would add libraries I do not presently need.

            ➥ Is there an avenue to start a new Vaadin 16 project using only plain Java Servlets to be run on Jetty or Tomcat without Spring/CDI? (or Vaadin 17 pre-release)

            Or has the Vaadin Ltd company decided to support only Spring now? (That would be most unfortunate.)

            How to add objects into Model after each request (Spring Boot)
            Asked 2019-Dec-19 at 21:07

            I'm developing a web application with Java and Spring Boot. What I would like to do is to add an object into the Model every time a request is received. Let me explain better what I'm doing and why I need it.

            The application is an eCommerce and I need every time a page is loaded the number of items inside the cart and the number of notifications a user has got. These information are displayed inside the menu in all the pages of the web app. Right now I'm requesting these information to through an ajax call after the page has been loaded. I would like to automatically add these information inside the Model and render and return all the pages with them already present without making any further request.

            I googled it and I found out that a way to solve this problem is to use an Interceptor. I implemented it following this tutorial but the only problem is that preHandle, postHandle and afterCompletion get called not only with the page requests but also with other kind of content like images, videos etc.



            Answered 2019-Dec-19 at 21:07

            When registering your interceptors in WebMvcConfigurerAdapter, you can also define a path pattern to include or exclude.

            Deploy Spring Boot application in Tomcat 6 (Traditional deployment)
            Asked 2019-Mar-26 at 11:40

            I trying to deploy a spring boot application (war) in tomcat 6 ( when a deploy in tomcat 7 and older i get no problem ), in fact deploying in tomcat 6 (servlet 2.5) is not possible using the new way (i will put the link that describe the new way in the bottom) because Spring Boot uses Servet 3.0 APIs to initialize the ServletContext (register Servlets etc.) so you can’t use the same application out of the box in a Servlet 2.5 container.

            the solution to deploy in spring that i found in the documentation (i will put the link in the bottom) is to add web.xml.

            Now, when I send a request after deploying i get this error :



            Answered 2019-Mar-26 at 11:40

            You are going against the Spring Boot requirements by trying to deploy to Tomcat 6. Even if you hack your application to start something might break later. Since you are on Spring Boot 1.5.9.RELEASE the docs mention it clearly:

            Tomcat 7 & 8.0 work with Spring Boot, but the default is to use Tomcat 8.5. If you cannot use Tomcat 8.5 (for example, because you are using Java 1.6) you will need to change your classpath to reference a different version.

            Tomcat 6 is legacy and running it's a security risk. It's security support ended on 31 December 2016 and you can't download it since 30 March 2017. Upgrade your Tomcat version.

            Adding Spring Security starter to my Spring Boot app automatically redirects all paths to one that's set in a completely different project
            Asked 2019-Mar-04 at 02:39

            I added Spring Security Starter dependency (I use Maven) to secure my app (following a tutorial); the problem is that once I add it, whenever I go to localhost to check my progress, I'm always redirected to a path that's coded in another project (I can't even find the view right now).

            I currently follow the tutorial on TutorialsPoint, but I use Spring Tools Suite 4 for adding dependencies, coding and running my Spring application instead of CLI on localhost:8080.

            I tried finding the view in question, tinkering with another project's web.xml, but I can't find the source of the problem, all I know is that Spring Security Starter is somehow mucking it up.

            Gradle - compileTestGroovy can't resolve main Application class
            Asked 2019-Jan-07 at 15:25

            I have a strange issue. Our project has been up and running for 6 years now and some package upgrades were long overdue. App backend is written in Java 8, tests in Java and Groovy and frontend in AngularJS 1.5

            App consists of 7 modules and whole project structure and build process is setup through gradle build files.

            In the process of updating libraries versions biggest one was mongodb upgrade from 4.0 and spring upgrade to 5.1.3 and spring_boot version from 1.2.6 to 2.1.1.

            I know, quite a few major upgrades and thanks to the all the tests we had I managed to change all our code to comply with the changes in new versions of the libraries. All tests are passing. Build of almost all the modules is working like a charm. Except for a module that consists of Groovy test classes. All the tests, when I run them from IntelliJ are passing, there are no compile or build errors.

            But when I try running gradle build the task testCompileGroovy fails because the import in one of the abstract test specification classes can't be resolved. And it's the import of the main Application class that's needed for classes parameter of @SpringBootTest annotation.

            Answered 2019-Jan-07 at 15:25

            The problem is that your api module is a Spring Boot project: by default it will not produce a standard jar but only an executable/fat jar (or war if you have war plugin applied). Even if you add a 'project' dependency compile project(':api') in the tests-api module, Gradle won't be able to provide classes from api module to the classpath of tests-api, because there is no standard jar built from api module (see more details about project dependency type here):

            A [Project] “lib” dependency is a special form of an execution dependency. It causes the other project to be built first and adds the jar with the classes of the other project to the classpath. It also adds the dependencies of the other project to the classpath.

            So I see two options in order to solve your issue:

            1) (PREFERRED) Configure SpringBoot plugin in api module to produce a standard jar

            build.gradle from api module:
