Spring Initializr. updateByExampleSelective!. Use the returned instance for further operations as the save operation might have changed the entity instance completely. MongoRepository - We demonstrate all the CRUD operations using this approach. Handle Exception for this Rest APIs is necessary: - Spring . insert. Person, Employee, etc.. ID is the data type used for id in the POJO class e.g. 5. Updating documents in a collection- For updates we can elect to update the first document found using MongoOperation's method updateFirst or we can update . - Create new entity object: Use native queries if JPQL does not work (you need to use native syntax of the underlying database), or when you want to tune performance (rarely). $ ./mvnw clean package. Mongo specific org.springframework.data.repository.Repository interface.. This namespace element will cause the base packages to be scanned for interfaces extending MongoRepository and create Spring beans for each of them found. For example, Spring Boot 1.3.3, which is the one we are using, sets 4.2.5.RELEASE as the Spring framework version. Spring Data provides a MongoRepository interface in the package org.springframework.data.mongodb.repository which contains all the methods necessary for CRUD operation. Navigate to https://start.spring.io. Creating a simple POJO class inside the Book.java file. 1. package com.mkyong.dao; import com.mkyong.model.Customer; import java.util.List; public interface CustomerRepositoryCustomAbc { List<Customer> findByAVeryComplicatedQuery(Long id, String name, String address) ; } 1.3 For implementation class, the class name is very strict, you need to follow the "core repository .
