In this article, Ill offer an overview of this support. Installing Oracle Enterprise Pack for Eclipse. Oracle Enterprise Pack for Eclipse 1. Eclipse installation via the normal plug in mechanisms. An especially convenient alternative is to download a complete version of Eclipse that comes with OEPE already configured. Once the plug ins have been installed, or the complete version of Eclipse with OEPE already configured has been installed, the availability of these plug ins can be verified by selecting the About Eclipse Platform option from the Help menu. Each of the five square buttons with rounded corners represents an installed plug in feature. The two features of particular interest for this article are the two features with rightmost buttons. The Spring IDE feature button is the furthest right feature button and the button to its left represents the OEPE plug ins. Oracle Enterprise Pack for Eclipse with the Spring Framework. The Spring Framework has become a widely used framework for generation of enterprise Java applications because of the many advantages that it offers. However, there are some aspects of working with the Spring Framework that can be improved through the use of the Spring IDE plug in that is included with  Oracle Enterprise Pack for Eclipse. One of the challenges that developers new to the Spring Framework encounter as they learn about the framework is understanding and working with the XML based Spring configuration files. Nick En Simon Pak Maar M N Hand. The Spring IDE functionality included with OEPE provides several features that make working with Spring XML more intuitive. These features include a Design view of Spring XML configuration files, Spring element and attribute completion, and detection and notification of any non compliant entries in the Spring context files. With OEPE, you can create a new Eclipse project as a Spring project. The following two images show how to select a Spring project from the New Project Wizard and how to add specific details on the Spring project when creating it. The wide range of capabilities offered by Spring Framework mean that there are many choices for Spring configuration. It can be difficult to learn and remember how various XML elements, attributes, and namespaces are related in a Spring configuration file. The next image shows how to select the wizard for creating a new Spring definition bean. Once the wizard for a Spring Bean Definition is selected, two steps in the creation wizard allow the name of the Spring context file to be specified and allow the applicable Spring Framework XSD based schemas to be selected. These two steps are shown in the next two images. The image above shows the many XSD namespaces that Spring supports. The namespace that is nearly always useful in Spring context files for declaring the Spring beans the beans namespace is pre selected as indicated in this screen snapshot. The context, util, and p namespaces are also commonly used in Spring applications. Assuming that those are selected and that the other settings shown in the previous screen snapshots are used, the generated Spring context file looks like that shown in the next screen snapshot of the Source tab in Eclipse. Using the Spring Bean Definition wizard allows the Spring context configuration file to be generated correctly and without mistyping. As the preceding screen snapshot demonstrates, the namespaces selected in the wizard are included and the appropriate schema. Locations are provided. The preceding image indicates that the Spring IDE provides a Design tab. This tab allows one to see a Spring XML configuration file as a series of two column rows rather than as raw XML. A particularly useful feature of this Design view is the ability to select applicable attributes, child elements, and other portions of the Spring configuration file from a list of valid possibilities. The next image demonstrates the Spring IDE displaying the available child elements for the Spring configuration root beans element. The choices are listed by right clicking on the elements name in the Design view. It is useful to be offered the possible child elements of the beans element. Without this functionality, one must remember or discover what possible child elements will work and must be sure not to mistype those entries. The preceding image also shows an option to add attributes as well. Adding attributes to the Spring configuration element with this mechanism offers the same advantages as adding child elements with this approach. There may be times when it is more convenient to edit Spring configuration files directly in the XML source than in the Design view. In such cases, another advantage of the Spring IDE is the auto completion of Spring context elements and attributes. This auto completion offers the same advantages as the Design view in terms of only presenting viable options. The next screen snapshot demonstrates the suggested child elements offered when I started to type a new element with the opening lt. Several valid choices are offered and the currently selected option, the bean element, has its documentation from the defining XML Schema displayed to help the developer decide if that is the appropriate choice. The inclusion of Springs XSD documentation means that a developer can stay focused on the IDE and not need to move back and forth between the IDE and the relevant XML Schema file. With the drop down selections offered by the Design view and the auto completion drop down selections offered in the Source view, it is much easier to generate a correct Spring context file. However, the benefits the Spring IDE provides for improving the configuration experience do not stop here. When an unrecognized value is specified in a Spring configuration file, the improper syntax is highlighted in red to mark improper syntax in Java code. The next screen snapshot demonstrates the indication that the bean child element was misspelled been. The Spring support provided with OEPE includes support for Spring 2. For example, one of the namespaces that can be selected for inclusion with the Spring Bean Definition wizard is the JMS namespace that was first available in Spring 2. The next screen snapshot shows that the 2. JMS inclusion.   Other namespaces have 2. Many of the Spring IDE features covered so far are largely possible due to the XML Schema Definitions XSDs that constrain the available elements and attributes and their relationships with one another. In the next screen snapshot, the Spring IDE reports two errors and one warning associated with my Spring context file. Validation of the Spring configuration file occurs during a Save. The first error reports that there is No setter found for the property another in class dustin. Spring 5, Embedded Tomcat 8, and Gradle a Quick Tutorial. TL DR In this article, we are going to learn how to use Gradle to structure a Spring 5 project with Tomcat 8 embedded. We will start from an empty directory and will analyze each step needed to create an application that is distributed as an berfat jar. This Git. Hub repository contains a branch called complete with the final code that we will have after following the steps described here. Why Spring. Spring is the most popular framework available for the Java platform. Developers using Spring can count on a huge, thriving community that is always ready to help. For example, the framework contains more than 1. Git. Hub and more than 1. Stack. Overflow are related to it. Besides that, Spring provides extensive and up to date documentation that covers the inner workings of the framework. As such, when starting a new Java project, Spring is an option that must be considered. Spring vs. Spring Boot. In the past, Spring was known for being hard to set up and for depending on huge configuration files. This was not a big problem as most of the applications out there were monoliths. This kind of application usually supports many different areas and solves a wide variety of problems inside companies. Therefore, it was quite common to know companies that had only one or two applications to support their daily operations. In scenarios like that, having these huge configuration files and a hard process to set up a new project was not a problem. However, this paradigm is getting outdated. Nowadays, many companies around the world are relying more on the microservices architecture and its benefits. As this architecture relies on multiple applications, each one specialized in a particular subject, using a framework that is hard to setup was something that developers were starting to avoid. This is why the team responsible for Spring decided to create a new project called Spring Boot. As described in the official site of the Spring Boot framework, this framework makes it easy to create stand alone, production grade Spring based applications that just run. They decided to take an opinionated view of the Spring platform and third party libraries so we can get started with minimal work. Why Embedded Tomcat 8. First of all, lets understand what embedded means. For a long time, Java developers shipped their applications as war Web ARchive and ear Enterprise ARchive files. These files, after being bundled, were deployed on application servers like Tomcat, Wild. Fly, Web. Sphere, etc. For the last couple of years, developers around the world started changing this paradigm. Instead of shipping applications that had to be deployed on running servers, they started shipping applications that contain the server inside the bundle. That is, they started creating jar Java ARchive files that are executable and that starts the server programmatically. What triggered this change is that the new approach has many advantages. For example To run a new instance of the application, it is just a matter of executing a single command. All dependencies of the application are declared explicitly in the application code. The responsibility for running the application isnt spread across different teams. The application is guaranteed to be run in the correct server version, mitigating issues. Also, as this approach fits perfectly in the microservices architecture that is eating the software development world, it makes sense to embed application servers. Thats why we will learn how to embed Tomcat 8, the most popular Java server, on Spring applications. Why Gradle. When it comes to dependency management and build tools on Java projects, there are two mainstream solutions to choose from Gradle and Maven. Both solutions are supported by huge communities, are constantly being developed, and are stable and extensible. Besides that, both Maven and Gradle fetch dependencies on similar ways and from similar sources usually from Maven repositories. In the end, choosing one solution or another is normally just a matter of taste or familiarity. There are certain edge scenarios that one solution performs better than the other. However, in most cases, both solutions will attend all our needs. In this article, we are going to use Gradle for one singular reason brevity. Maven configuration files are usually too verbose they are expressed on XML files. On the other hand, Gradle configuration files are expressed on Groovy, a JVM dynamic programming language known for having a concise and tidy syntax. Creating the Project. Now that we understand why we chose to use Gradle, Spring 5, and an embedded Tomcat 8 server, lets see how to put all these pieces together. The first thing that we will do is to clone an empty Gradle project. After that, we will explore adding the Tomcat 8 dependency and how to bootstrap it programmatically. Lastly, we will see how to configure and secure a Spring 5 project that works as a RESTful API and that handles JSP Java. Server Pages files. Cloning the Gradle Project. There are multiple ways we can create a new Gradle project. For example, if we have Gradle installed on our machines, we could easily issue gradle init to get the basic files created for ourselves. However, to avoid having to install Gradle everywhere, we will clone a Git. Hub repository that already contains these files. The following commands will clone the repository for us and create the main package clone basic files. After executing the last command, we will have the com. Gradle files that we will need. Embedding Tomcat 8. To embed and bootstrap an instance of Tomcat 8, the first thing we need to do is to add it as a dependency to our project. We do that by adding a single line to the dependencies section of the build. After adding the Tomcat 8 dependency, we have to create a class called Main in the com. Tomcat. import java. File. import java. IOException. public class Main. PORT 8. 08. 0. public static void mainString args throws Exception. String app. Base. Tomcat tomcat new Tomcat. Base. Dircreate. Temp. Dir. tomcat. PortPORT. Host. set. App. Baseapp. Base. tomcat. Webapp, app. Base. Server. await. Abstract. Embedded. Servlet. Container. Factory. private static String create. Temp. Dir. File temp. Dir File. create. Temp. Filetomcat. PORT. Dir. delete. Dir. mkdir. temp. Dir. delete. On. Exit. Dir. get. Absolute. Path. catch IOException ex. Runtime. Exception. Unable to create temp. Dir. java. io. tmpdir is set to System. Propertyjava. io. As we can see, running an instance of Tomcat 8 programmatically is quite easy. We just create a new instance of the Tomcat class, set a few properties on it, and call the start method. Two things worth mentioning are The server port is hardcoded in the code above 8. Even though we wont use it, the latest version of Tomcat requires us to define a base directory. Therefore, we simply create a temporary directory through the create. Temp. Dir method that is marked to be excluded when the JVM ends its execution. Bootstrapping Spring 5. Having the Tomcat 8 dependency configured and the code to initialize the server created, we can now focus on configuring Spring 5 in our project. The first step is to add the spring webmvc dependency. To do that, lets open the build. RELEASE. This is the only Spring dependency that we will need for the time being.
