1）[springboot简单启动][springboot]

2）集成MongoDB

pom

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

application.properties

#配置mongodb
    #spring.data.mongodb.uri=mongodb://192.168.1.127:27017
    spring.data.mongodb.host=192.168.1.127
    spring.data.mongodb.port=27017
    spring.data.mongodb.database=xx
    #spring.data.mongodb.username=xxx
    #spring.data.mongodb.password=xxxx

DemoController

@RestController
    @RequestMapping("/mongo")
    public class MongodbController {
    
        @Resource
        private UserMdMapper userMdMapper;
    
        @RequestMapping("/save")
        private String save() {
            UserMd userMd = new UserMd();
            userMd.setId(1);
            userMd.setUserName("ocean");
            userMd.setAge(18);
            userMdMapper.insert(userMd);
            return "success";
        }
    
        @RequestMapping("/saveOrUpdate")
        private String saveOrUpdate() {
            UserMd userMd = new UserMd();
            userMd.setId(2);
            userMd.setUserName("ocean");
            userMd.setAge(18);
            userMdMapper.save(userMd);
            return "success";
        }
    
        @RequestMapping("/detail")
        private UserMd detail(Integer id) {
            Optional<UserMd> userMdOptional = userMdMapper.findById(id);
            if (userMdOptional.isPresent()) {
                return userMdOptional.get();
            }
            return null;
        }
    
        @RequestMapping("/list")
        private List<UserMd> list(String name) {
            UserMd userMd = new UserMd();
            userMd.setUserName(name);
            Example<UserMd> example = Example.of(userMd);
            return userMdMapper.findAll(example);
        }
    }

MdEntity

@Data
    @Document("user")
    public class UserMd {
    
        @Id
        private Integer id;
        private String userName;
        private Integer age;
    
    }

MdMapper

@Repository
    public interface UserMdMapper extends MongoRepository<UserMd,Integer> {
    
    }
