You can run the app using - mvn spring-boot:run The app will start on port 8080. Next, extract the zipped Spring Boot project then copy or move to your Java projects folder. Conclusion Spring Boot makes it very easy to get a Spring application talking to a Mongo database.

We are creating this tutorial especially for Java Web newbie, for the master of java we need any suggestion and critics in the comments below. Second, wrapping all development and runtime together using the same port. To create it on Netbeans just right click on project name from projects left panel then choose new then choose Java Class. He has more than 10 years of experience with different aspects of Spring and Java design and development.

Spring Data, Spring Boot, MongoDB (Example & Tutorial)

We will make use of tool for quickly setting up the project. We will use just two dependencies as shown below: Download the project and unzip it. Maven Dependencies Though we spring boot mongodb completed the setup with the tool, if you want to set it up manually, we use Maven build system for this project and here are the dependencies we used: Copy 4. Spring Data MongoRepository provide us common functionalities that we can easily plug-in and use it. Let us define our Repository interface. We will use Spring Boot properties to do this. If you have a local instance without authorization enabled, you can just remove the first three lines of configuration. Defining the Spring Controller Let us finally move to making our Controller class. Notice that we do not have to write any database interaction code in the interface as Spring Data does it all for us. Adding a new User We will be adding a new user in the function below. We will elaborate this when we have defined the MongoTemplate version as well. With MongoTemplate, you will see that we have much more granular control over what we query and what data is included in the results. We construct a query and passed required parameters. What will interests you more is the getUserSetting query. Below code snippet shows the changes required to use MongoTemplate for reading user settings. Below image shows the output spring boot mongodb Postman app. This is not possible with MongoTemplate. So, this is completely your call what to choose when you develop your idea. Feel free to leave comments below. Download the source code from below link. I started the project from Spring initializer and went through your tutorial. I am going with the 1.

Our model now has a year that is represented by an integer and any existing documents will just have a Null year. What I wanted to do is to have a simple web service that would allow saving and reading some data from the database. You can use the following repository straight away by using Autowire. Fill with the codes below. If we want to run communication tests in the environment as close to the production as possible, a better solution is to use an environment container such as Docker. If you have a local instance without authorization enabled, you can just remove the first three lines of configuration. Then, create an interface named TodoRepository inside repositories package with the following contents - package com. Next, we will create a new Spring Boot Gradle project using. Second, make sure you have Maven 3. Make sure that your todo-list. What will interests you more is the getUserSetting query.
