JeecgBoot与MongoDB集成实战文档 JeecgBoot与MongoDB集成实战文档

坐标引入依赖

org.springframework.boot spring-boot-starter-data-mongodb

升级积木报表
jeecgboot2.4.6/3.0等版本集成mongodb会报mongoTemplate错误，官方已经提供了解决方案，将积木报表升级到最新版即可。

org.jeecgframework.jimureport jimureport-spring-boot-starter 1.4.2

【JeecgBoot与MongoDB集成实战文档】之后在application-dev.yml文件中，加入mongoDb的配置项

spring: data: mongodb: uri: mongodb://localhost:27017/springboot-db

创建实体类

package org.jeecg.modules.mongodb.entity; import org.springframework.data.annotation.Id; public class Customer { @Id public String id; public String firstName; public String lastName; public Customer() {} public Customer(String firstName, String lastName) { this.firstName = firstName; this.lastName = lastName; } @Override public String toString() { return String.format( "Customer[id=%s, firstName='%s', lastName='%s']", id, firstName, lastName); } }

创建Repository

package org.jeecg.modules.mongodb.dao; import org.jeecg.modules.mongodb.entity.Customer; import org.springframework.data.mongodb.repository.MongoRepository; import java.util.List; public interface CustomerRepository extends MongoRepository { Customer findByFirstName(String firstName); List findByLastName(String lastName); }

测试用例
用两种方式测试mongoDB，分别为MongoRepository和MongoTemplate

package org.jeecg.modules.mongodb; import org.jeecg.common.api.vo.Result; import org.jeecg.modules.mongodb.dao.CustomerRepository; import org.jeecg.modules.mongodb.entity.Customer; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.mongodb.core.MongoTemplate; import org.springframework.web.bind.annotation.*; import java.util.HashMap; import java.util.Map; /** * 测试mongodb */ @RestController @RequestMapping("/mongo") public class MongoController { @Autowired private MongoTemplate mongoTemplate; @Autowired private CustomerRepository repository; @GetMapping("/test1") public Result TestMongoDb(){ Map map = new HashMap<>(); map.put("jeecg","mongodb-jeecg"); mongoTemplate.insert(map, "testMongoDb"); return Result.OK("存入成功"); } @GetMapping("/test2") public Result TestMongoDb2(){ repository.deleteAll(); // save a couple of customers repository.save(new Customer("Alice", "Smith")); repository.save(new Customer("Bob", "Smith")); // fetch all customers System.out.println("Customers found with findAll():"); System.out.println("-------------------------------"); for (Customer customer : repository.findAll()) { System.out.println(customer); } System.out.println(); // fetch an individual customer System.out.println("Customer found with findByFirstName('Alice'):"); System.out.println("--------------------------------"); System.out.println(repository.findByFirstName("Alice")); System.out.println("Customers found with findByLastName('Smith'):"); System.out.println("--------------------------------"); for (Customer customer : repository.findByLastName("Smith")) { System.out.println(customer); } return Result.OK("存入成功"); } }
