在SpringBoot中使用MongoDB

application.yml配置文件：

spring:
  datasource:
    name: springboot
    url: jdbc:mysql://127.0.0.1:3306/springboot?serverTimezone=UTC&characterEncoding=utf-8
    username: root
    password: root
    driver-class-name: com.mysql.jdbc.Driver
  data:
    mongodb:
      database: local
      host: 127.0.0.1
      port: 27017

pojo：（@Id可以没有，使用MongoDB自带的主键，注意实现Serializable接口)

@Document(collection = "user")
public class User implements Serializable {

    @Id
    private String id;
    private String name;
    private String age;
    private String password;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getAge() {
        return age;
    }
    public void setAge(String age) {
        this.age = age;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

repository：

public interface UserRepository extends MongoRepository<User, String> {
}

使用：

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Autowired
    private MongoTemplate mongoTemplate;

    @Override
    public User query(String id) {
        User user = userMapper.selectById(id);
        mongoTemplate.insert(user);
        return user;
    }
}
