Question

这是一个严肃的问题＆＃34; Springers＆＃34; ...

我想使用MongoRepository。所以我去了spring.io website tutorial for MongoDB CRUD operations;

第一个问题是他们正在使用Spring启动。第二个问题是他们在接口上使用@Autowired。该注释似乎能够创建一个对象（以后称之为方法......）

所以....我使用普通的春季MVC并且@Autowired似乎没有在那里工作。

我如何＆＃34;实例化＆＃34; MongoRepository没有@Autowired mvc的package hello; import java.util.List; import org.springframework.data.mongodb.repository.MongoRepository; public interface CustomerRepository extends MongoRepository<Customer, String> { public Customer findByFirstName(String firstName); public List<Customer> findByLastName(String lastName); }接口？

MongoRepository扩展接口

@Autowired

包含package hello; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class Application implements CommandLineRunner { @Autowired private CustomerRepository repository; public static void main(String[] args) { SpringApplication.run(Application.class, args); } @Override public void run(String... args) throws Exception { 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); } } }

您应该使用#rateyo1 .jq-ry-normal-group svg { fill:purple; stroke:lime; stroke-width:20; } #rateyo1 .jq-ry-rated-group svg { fill:lime; stroke:purple; stroke-width:20; }对<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/rateYo/2.3.2/jquery.rateyo.min.js"></script> <link href="https://cdnjs.cloudflare.com/ajax/libs/rateYo/2.3.2/jquery.rateyo.min.css" rel="stylesheet"/> <div> <div id="rateyo1" class="rateyo" data-rateyo-rating="1.5" data-rateyo-num-stars="5"> </div> </div>课程进行注释，并确保通过Spring的组件扫描将其选中。然后，您可以根据需要Repository将其分类。

要明确你不要＆＃34;实例化＆＃34;界面。您声明了对该接口的实现的依赖（通过@Repository）并假设Spring Data MongDB在类路径上Spring将创建一个运行时实现并使其可用作要注入的bean。

如何在spring mvc中实现Spring引导@Autowired来实例化MongoRepository接口？
