#mongodb连接
    spring.data.mongodb.uri=mongodb://192.168.1.105:27017/test

实体类：

package com.yang.domain;
    
    import org.springframework.data.annotation.Id;
    import org.springframework.data.mongodb.core.mapping.Document;
    import org.springframework.data.mongodb.core.mapping.Field;
    
    
    @Document(collection="test")//mongo数据库名
    public class User2 {
    	@Id
    	@Field("id")//声明mongo数据库中属性名与pojo类的属性名一一对应
    	private Integer id;
    	
    	@Field("name")
    	private String name;
    	
    	@Field("telphone")
    	private String telphone;
    	
    	
    	public Integer getId() {
    		return id;
    	}
    
    	public void setId(Integer id) {
    		this.id = id;
    	}
    
    	public String getName() {
    		return name;
    	}
    
    	public void setName(String name) {
    		this.name = name;
    	}
    
    	public String getTelphone() {
    		return telphone;
    	}
    
    	public void setTelphone(String telphone) {
    		this.telphone = telphone;
    	}
    
    	@Override
    	public String toString() {
    		return "User [id=" + id + ", name=" + name + ", telphone=" + telphone + "]";
    	}
    
    
    
    }

接口类：

package com.yang.repo;
    
    import org.springframework.data.mongodb.repository.MongoRepository;
    
    import com.yang.domain.User2;
    
    //mongo操作
    public interface User2Repo extends MongoRepository<User2, Integer>{
    	
    }

测试类：

//测试mongo操作
    @Autowired
    private User2Repo user2Repo;
    
    
    User2 user2=new User2();
    user2.setId(2);
    user2.setName("肉哒哒");
    user2.setTelphone("123437");
    //保存
    user2Repo.save(user2);
    		
    		
    //查找
    Optional<User2> userFind=user2Repo.findById(1);
    System.out.println("================="+userFind.get().getName());
