英文:
No bean named 'mongoTemplate' available. Spring Boot + MongoDB
问题
I'm building a backend using Spring Boot and MongoDB, first I'm making the user repository, service, and controller, and getting this error:
***************************
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.
Here's the code:
UserController:

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));
}
}
UserRepository:
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);
}
UserService:
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);
}
MainApplication:
package com.package.package;

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);
}
}
I am using as a reference a past project that I made (the difference is that this was done with postgres). Any other information you want, just tell me.

尝试添加此依赖项:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
英文:
Try adding this dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

在这种情况下,这绝对不是大多数情况下错误的原因,但它确实发生在我身上,我花了相当多的时间寻找原因,所以我想在这里发布“解决方案”。
在我的情况下,在最初禁用自动配置(application.yml)后,我忘记删除以下这些行:
spring.autoconfigure.exclude:
- org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration
- org.springframework.boot.autoconfigure.data.mongo.MongoDataAutoConfiguration
英文:
While this is certainly not the reason for the error in most cases, the fact that it happened to me and I spent a fair amount of time looking for the reason made me want to post "the solution" here.
In my case I forgot to remove these lines again after disabling autoconfiguration initially (application.yml):
spring.autoconfigure.exclude:
- org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration
- org.springframework.boot.autoconfigure.data.mongo.MongoDataAutoConfiguration

希望这个答案也能帮助到某人。
如果您在代码块中具有以下带有参数的注释,请将其删除。
exclude = {MongoAutoConfiguration.class}
例如:
@SpringBootApplication(exclude = {MongoAutoConfiguration.class})
之后:
@SpringBootApplication
英文:
Hopefully, this answer too can help someone.
If you have following annotation with the parameter somewhere in your code block remove it.
exclude = {MongoAutoConfiguration.class}
Ex: Before
@SpringBootApplication(exclude = {MongoAutoConfiguration.class})
After
@SpringBootApplication

我之前的配置是:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
<version>1.5.2.RELEASE</version>
</dependency>
我只是移除了版本标签,然后它就起作用了。
英文:
I Had
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
<version>1.5.2.RELEASE</version>
</dependency>
Just removed the version tag and its worked
