3 添加测试类

class DemoInfo {
    //id属性是给mongodb用的，用@Id注解修饰
    @Id
    private String id;
    private String name;
    private int age;
    public String getName() {
         return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

interface  DemoInfoRepository  extends MongoRepository<DemoInfo, String> {
    DemoInfo findByName(String name);
}

@RestController
public class MongoTest {
    @Autowired
    private DemoInfoRepository demoInfoRepository;

    @RequestMapping("save")
    public String save(){
        DemoInfo demoInfo = new DemoInfo();
        demoInfo.setName("张三");
        demoInfo.setAge(20);
        demoInfoRepository.save(demoInfo);
        demoInfo = new DemoInfo();
        demoInfo.setName("李四");
