![]() To run the java application from an external Command Prompt: Extra configuration includes an additional logging dependency, a resource reference to the Spring configuration file, one additional property, and three maven plug-in references for compiling and packaging the jar. This extra configuration ensures that the project is correctly packaged into a jar file, with all the necessary dependencies to run. However, if you want to run the application from an external Command Prompt, you will need the added configuration. The extra configuration information is not necessary for running the application from within Eclipse. Note the pom.xml contains a some extra configuration information not shown above. Successful Console Output of Java Application Running the Application from a Command PromptĪll the source code for this project is available on GitHub. printf( "Our son drives his %s too fast!\n", obj3. printf( "Is her %s clean, now? %s\n\n", obj2. printf( "Is my %s tuned up, yet? %s\n\n", obj1. MaintainVehicle maintain = new MaintainVehicle() Public static void main( String args) SuppressWarnings( "resource")ĪpplicationContext context = new ClassPathXmlApplicationContext( The main App class uses an ApplicationContext IoC Container to instantiate three Vehicle POJOs from the Spring Beans defined in the Beans.xml Spring configuration. The main class then instantiates an instance of the MaintainVehicle class, passes in the Vehicle objects and calls MaintainVehicle’s two methods. There are three Spring Beans defined in the xml-based Spring configuration file, representing three different vehicles. The sample Spring application is based on vehicles. Open the App.java class file and replace the contents with the supplied App.java class file.Add the supplied Beans.xml Spring configuration file to the project at the ‘src/main/java’ folder.Add the supplied Vehicle.java and MaintainVehicle.java class files to the project, in the same classpath as the App.java class.We will replace the contents of main App class with our sample code. We will add two new java classes and a Spring configuration file. Next add the supplied Code to the project. Local Maven Repository Location Sample Code Project for blog post about the use of Spring with Eclipse and Maven. Add the path to Maven’s bin directory to your system’s ‘PATH’ Environmental Variable.Assuming you are Windows, unzip the ‘apache-maven-3.1.1’ folder and place in your ‘Program Files’ directory.At the time of this post, Maven is at version 3.1.1. Download the latest version of Maven from the Apache Maven Project website.Installing Maven is simple process, requiring minimal configuration: Modify the project to allow execution from an external command prompt.Demonstrate a simple example of Spring Beans and ApplicationContext.Adding Spring dependencies to the project.Linking the installed version of Maven to Eclipse.The steps covered in this post are as follows: According to their website, STS is an Eclipse-based development environment, customized for developing Spring applications. ![]() You can download and add the Spring artifacts yourself, or go full-bore with GoPivotal’s Spring Tool Suite (STS). Note there are alternatives to integrating Spring into Eclipse, using Maven. Maven will take care of downloading and managing the required Spring artifacts into our Eclipse-based project. We will use Maven for one of its best known features, dependency management. Conveniently, Maven is tightly integrated with Eclipse. Maven is a marketed as a project management tool, centralizing a project’s build, reporting and documentation. In the following post, I will demonstrate the ease of integrating Spring with Eclipse, using Maven. The use of Spring within Eclipse is very common. Similar to Spring in terms of wide-spread adoption, Eclipse is leading Java IDE, competing with Oracle’s NetBeans and JetBrain’s IntelliJ. Spring focuses on the ‘plumbing’ of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.” According to GoPivotal’s website, “The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications. All source code for this post is available on GitHub.Īlthough there is a growing adoption of Java EE 6 and CDI in recent years, Spring is still a well-entrenched, open-source framework for professional Java development. Learn how to install, configure, and integrate these three leading Java development tools. Integrate the Spring Framework into your next Eclipse-based project using Apache Maven.
