There is an official tool called Spring Initializr.Д«y default, all the advanced options are hidden. Instead of creating the application yourself, you can generate it with all the required settings and dependencies. When you are creating a new app, the process is fortunately very easy.

In this post, we'll examine how to package Spring Boot app as WAR, without sacrificing direct executability. For example, if you are tied by your company policies and need to deploy to a provided app server. This has many advantages, but sometimes you may need to have your Spring Boot app as a traditional WAR instead. With Spring Boot, this approach is inverted as the app server is directly in your JAR. And you need to have such server prepared for each environment. You need to have such server installed, configured, and then deploy your applications to it. Traditional Java web applications need a servlet container (application server) to run. You can run them directly by java -jar command. WAR vs JARД«y default, Spring Boot applications are packaged as executable JAR files with embedded Tomcat. Otherwise, Spring MVC will raise the infamous error вЂњ Caused by: to change your JAR Spring Boot app to be packaged and deployed as WAR without sacrificing direct execution capabilities of embedded app server. We need to connect the HTML login form to a data transfer object (also known as command object, form object, form-backing object) of type LoginForm. I will illustrate the use of WebJars Bootstrap 4 module to our demo project.Д®ventually, our main build configuration adle should look like this.Д¬lasspath ( ':spring-boot-gradle-plugin:$ Data Binding Thus, ItвЂ™s truly convenient for Java based web projects to bundle popular front-end libraries such as jQuery, Bootstrap, Font-Awesome, to name but a few.

In case you need JavaServer Pages Standard Tag Library (JSTL), just add вЂњ rvlet:jstlвЂќ.ДЄpart from those, I also consider to use WebJars as it provides client-side web libraries in terms of JAR files. Note that the embedded Tomcat package does not include JSP by default, we must add the module вЂњ :tomcat-embed-jasperвЂќ as well. I pick the module вЂњ spring-boot-starter-webвЂќ that adds an embedded Tomcat servlet container and Spring MVC. Spring Boot 2 comes with a number of starters (conventionally named as spring-boot-starter-*) to help us integrating appropriate dependencies in our Spring projects. The other non-default option is вЂњ Gradle ConfigвЂќ, as mentioned above.

For less verbose build configuration, I will opt for Gradle build instead of Maven.ДЇor instance, with the вЂњ New ProjectвЂќ wizard with Spring Initialzr in Intellij IDEA, I picked вЂњ WarвЂќ for вЂњ PackagingвЂќ. We can quickly create a new Spring Boot project using Spring Initializr web site or via command line or IDE (e.g. The versions that I consider here are Spring Boot 2.1 and respectively Spring 5.1. This post merely focuses some on major aspects on bringing Spring Boot 2 and Spring Web with JSP together. It took me much unexpected effort and trial-and-error to get things right not to mention numerous doвЂ™s and donвЂ™ts got undocumented or lost among a bunch of documentations. Most of the significant information are scattered throughout the Internet and most of the useful tutorials are sort of вЂњ just-follow-these-steps-and-it-will-guarantee-to-work-but-nothing-will-be-explainedвЂќ. controllers, validations, JSP views) working. It is still working fine after upgrading to Spring 5 and corresponding dependent libraries such as Hibernate 5, HikariCP 3 and Apache CXF 3.3.Д®xploring further into Spring ecosystem, I decided to give a shot on migrating to Spring Boot 2 whilst keeping most of the existing MVC (e.g.

One of my past projects relied heavily on XML based configurations and JSP technologies dated back to Spring Framework 3.x.
