报错：Not registered via @EnableConfigurationProperties, marked as Spring component, or scanned via @ConfigurationPropertiesScan 的解决方案

方法一：直接添加注解@Component，将其标注为Spring组件

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Data
@Component
@ConfigurationProperties(prefix = "my.server")
public class MyServerProperties {
    private String name;
    private String ip = "127.0.0.1";
    private int port = 9797;
}

方法二：加注解@EnableConfigurationProperties ，将其标注为配置类

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;

@Data
@EnableConfigurationProperties(MyServerProperties.class)
@ConfigurationProperties(prefix = "my.server")
public class MyServerProperties {
    private String name;
    private String ip = "127.0.0.1";
    private int port = 9797;
}

方法三：在springboot启动类上添加 @ConfigurationPropertiesScan 注解，开启配置文件扫描

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationPropertiesScan;

@ConfigurationPropertiesScan
@SpringBootApplication
public class MongodbApplication {


    public static void main(String[] args) {
        SpringApplication.run(MongodbApplication.class, args);
    }

}
