springboot整合mongodb

1.代码实现：

添加依赖

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>

控制层

@RestController
public class UserController {

    @Autowired
    private IUserService userService;


    @GetMapping("/findAll")
    public List<User> findAll(){
        return userService.findAll();
    }

    @GetMapping("/findByName")
    public User findByName(String name){
        return userService.findByName(name);
    }

    @PostMapping("/add")
    public String add(User user){
        return userService.add(user);
    }

    @PutMapping("/edit")
    public String edit(User user){
        return userService.edit(user);
    }

    @DeleteMapping("/deleteById")
    public String deleteById(Long id){
        return userService.deleteById(id);
    }



}

接口层

@Service
public class UserServiceImpl implements IUserService {

    @Autowired
    private UserRepository userRepository;


    @Override
    public List<User> findAll() {
        return userRepository.findAll();
    }

    @Override
    public User findByName(String name) {
        return userRepository.findByName(name);
    }

    @Override
    public String add(User user) {
        userRepository.save(user);
        return "添加成功";
    }

    @Override
    public String edit(User user) {
        userRepository.save(user);
        return "修改成功";
    }

    @Override
    public String deleteById(Long id) {
        userRepository.deleteById(id);
        return "删除成功";
    }
}

访问层

public interface UserRepository extends MongoRepository<User, Long> {

    User findByName(String name);

}

实体类

@Data
public class User {

    @Id
    private Long id;

    private String name;
    private Integer age;

}

2.效果实现：

运行项目，打开postman发起请求添加数据

查询数据
