没有名为“mongoTemplate”的豆子可用。弹簧靴 + MongoDB

我正在使用Spring Boot和MongoDB构建后端,首先我正在制作用户存储库,服务和控制器,并得到这个错误:
***************************
APPLICATION FAILED TO START
***************************
Description:
Field userRepository in com.package.package.controller.UserController required a bean named 'mongoTemplate' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean named 'mongoTemplate' in your configuration.
代码如下:
用户控制器:
package com.package.package.controller;
import com.package.package.entities.User;
import com.package.package.repositories.UserRepository;
import org.bson.types.ObjectId;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;
import java.util.List;
@RestController
@RequestMapping("/users")
public class UserController {
@Autowired
private UserRepository userRepository;
@GetMapping(value = "/")
public List<User> getAllUsers() {
return userRepository.findAll();
}
@GetMapping(value = "/{id}")
public User getUserById(@PathVariable("id") ObjectId id) {
return userRepository.findBy_id(id);
}
@PutMapping(value = "/{id}")
public void modifyUserById(@PathVariable("id") ObjectId id, @Valid @RequestBody User user) {
user.set_id(id);
userRepository.save(user);
}
@PostMapping(value = "/")
public User createUser(@Valid @RequestBody User user) {
user.set_id(ObjectId.get());
userRepository.save(user);
return user;
}
@DeleteMapping(value = "/{id}")
public void deleteUser(@PathVariable ObjectId id) {
userRepository.delete(userRepository.findBy_id(id));
}
}
用户存储库:
package com.package.package.repositories;
import com.package.package.entities.User;
import org.bson.types.ObjectId;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface UserRepository extends MongoRepository<User, String> {
User findBy_id(ObjectId _id);
}
用户服务:
package com.package.package.service;
import com.package.package.entities.User;
import org.bson.types.ObjectId;
import java.util.List;
public interface UserService {
User save(User user);
User findbyid(ObjectId _id);
List<User> getAll();
void delete(User user);
}
主要应用:
package com.package.package;
import com.package.package.repositories.UserRepository;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;
@SpringBootApplication
@EnableMongoRepositories(basePackageClasses = UserRepository.class)
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
我使用我过去的一个项目作为参考(不同之处在于这是用postgres完成的)。你想要的任何其他信息,只要告诉我。提前致谢。
更新:这是pom.xml
