This is the collection that will be copied and pasted into your target collection.Ĭlick Execute to run the import, or save the import as a task by clicking Save task (as). Next, choose the source collection from the tree. Now that we’ve configured the target database, let’s define the source database.Ĭlick on Connect to source and choose the source MongoDB connection from the Connection Manager. Alternatively, drag and drop it from the Connection Tree.ĭo the same for Target collection. Then, choose an insertion method from the dropdown menu. This will open the Collection Import tab.ĭefine the Target database by typing its name and choosing it from the auto-detected list. Open the Import Wizard and select Another collection as the import format. Looking to copy MongoDB collections to another database? Here’s a quicker way. Once done, you can save the export as a task, which you can run on-demand or schedule for later, or execute the task immediately.

This will open up the two sub-tabs, Source options and Target options. We can directly use save() method to perform this operation.Open the Import Wizard. Once, we have our MongoDB connection property defined in the application.properties file, spring automatically creates an instance of MongoTemplate and we can directly inject it in our repo class and execute criteria queries using MongoTemplate.īelow are some of the examples of using criteria query using MongoTemplate. Now let us create some entries in our init(EmployeeRepository employeeRepository)") For this example, we have an Employee model class Employee String String name To get started with the default and generic methods defined in Spring Data Repositories, we need to have a model class and a repository class that extends MongoRepository. Auto Generated Methods with Mongo Repositories You can follow my previous article for Spring Boot MongoDB Configuration. To get started with the examples, you need to have a Spring Boot MongoDB configured app running on your local machine.
We will learn all these methods to create and run queries with examples. Using Criteria Query with MongoTemplate.Auto Generated Methods with Mongo Repositories.Primarily, there are 4 ways with which we can query MongoDB from a spring boot application. For this, we will have a spring boot MongoDB application setup and create sample examples of all our learnings.
We will learn to create various custom dynamic queries with multiple MongoDB operators to get started. In this article, we will learn about Spring data MongoDB queries with different ways to create and execute MongoDB queries in a spring boot project.
