But additionally, I want to show challenging problems that can occur during the development while using the Spring Boot. First goal is to show how it is easy to start a web service with embedded tomcat and embedded H2 database. This is the main goal of the project. Secondly, we are using Spring and I have used dependency injection. But what is a challenging problem about dependency injection. Assume that you have two implementations ready for one implementation, how are you going to select the implementation?

I'll explain several ways but also I'll demonstrate how we can select our implementation via external configuration so that we can update our configuration and don't need to touch the code, restart our jar file and that's all. Thirdly, I also have demonstrated how to use Java Application Configuration within the double implementation for the single interface scenario I've explained above. Lastly, I will explain all the deployment details, the main configuration of the whole project including H2 database configuration.

We are going to build a demo app named as consultant-api. This will be a simple web service with basic CRUD operations. I'm going to demonstrate default and external configuration, how to use multiple implementation and autowire them within the code and outside the code with an external configuration file.

Our app will be a standalone application that we can use independently, and we are going to use an embedded tomcat, an embedded H2 database. Whenever there is a new framework on the town, you must think two thinks. One, why should I use this framework which means "what are the benefits of this framework", also can be interpreted like "what this framework solves? Two, "When should I use this framework? When we make a web service with spring framework, we have to generate a war file, we need to configure web.

All of these increases the cost of time. So instead of writing your code, doing your development, you a lot of time is wasted during the configuration. This is where Spring Boot comes to the action.

Spring Boot simplifies configuration, reduces boilerplate code that puts no any value to your software development. So, what Spring Boot solves is the time lost for the configuration.

For example, you can create a web service with Spring Boot that runs on an embedded Tomcat server which is automatically configured and you don't have to deal with the configuration.

You can do all your configuration parameters via default application properties. Also you can connect to an H2 embedded database, same applies for the configuration here. Secondly, you don't have to generate a war file.It will ask several questions including password for keystore.

We will make the password 'abcd' for this example. It is very important to match First Name Last Name is the same as the host-name of your server. If you are playing in localhost, enter "localhost" as your name. Use node1. Let the client use node Note: the commands in the source dzone link has typos.

Try the service from browser. The browser will ask which certificate to use you will see 'localhost' there. Skip to content. Instantly share code, notes, and snippets.

The client executes the following steps:. The application uses the library by adding it to the classpath via Apache Maven dependency. That is:. In order to activate the library, the EnableCamundaRestClient has been put on the configuration class of the application. The interesting part is now the ProcessClient component. This Spring Component has several methods marked with Scheduled annotation to demonstrate the time-based execution of desired functionality.

To do so, the component has two injected resources, both marked with the Qualifier "remote" annotation. This annotation indicates that the remote version of the Camunda API services are used. In order to configure the library, a block of properties e. The values specify the location of the remote process engine:. To run this example, you will need the server part from the next example. To activate the server part only, please run from command line:. The example demonstrates the usage of the library for accessing a process engine via REST from a Camunda process application.

The key difference to the previous example is that the required Camunda classes are already present on the classpath and an engine is initialized and is running.

I hope it helps you. This application is packaged as a war which has Tomcat 8 embedded. No Tomcat or JBoss installation is necessary. You run it using the java -jar command. The service is just a simple hotel review REST service. It uses an in-memory database H2 to store the data. If your database connection properties work, you can call some REST endpoints defined in com.

You can use this sample service to understand the conventions and configurations that allow you to create a DB-backed RESTful service. Once you understand and get comfortable with the sample app you can add your own services following the same patterns as the sample service. Spring Boot is an "opinionated" application bootstrapping framework that makes it easy to create new RESTful services among other types of applications.

It provides many of the usual Spring facilities that can be configured easily usually without any XML. In addition to easy set up of Spring Controllers, Spring Data, etc. Spring Boot comes with the Actuator module that gives the application the following endpoints helpful in monitoring and operating the service:.

The 'test' profile runs on H2 in-memory database. Default username is 'sa' with a blank password. Make sure you disable this in your production profiles. This project uses an in-memory database so that you don't have to install a database in order to run it. Since the project uses Spring Data and the Repository pattern, it's even fairly easy to back the same service with MongoDB. Skip to content.

But the same data i am passing through postmani am able to get response body. Can you give any suggestion on what could be the reason. RestTemplate usage is explained only for endpoint URI with the default port Thanks in advance. I am trying to call a third party api gateway from my server using RestTemplate.

Please have a look at the below link. Any leads will be appreciated. I tried using the restTemplate. I know the json I am passing in is working because I can use swagger and get successes, but when I use RestTemplate, I am getting error media type.

So is there something I need to inject or setup with the RestTemplate before I can run it? Your tutorials are really very helpful……Can you please let me know how can we use OAuth 2.

But whenever i am trying to access this url by passing name parameter I am getting Error. Please suggest what could be the problem. I have tried all possible ways. Your tutorials are very nice and I follow them regularly. I have an issue that when I access your site from my iPad, the right most part of code samples is getting truncated and there is no scroll bar to view the entire line.
