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:

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));
    }
}

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 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);
    }

}

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:

&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-data-mongodb&lt;/artifactId&gt;
&lt;/dependency&gt;

答案2

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

答案3

得分: 2

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

答案4

得分: 1

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

&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-data-mongodb&lt;/artifactId&gt;
&lt;version&gt;1.5.2.RELEASE&lt;/version&gt;
&lt;/dependency&gt;

Just removed the version tag and its worked
