1、引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
2、在属性类上添加注解
@ConfigurationProperties(prefix="server")
public class ServerProperties {
private String name;
private Host host;
// ... getter and setters
private static class Host {
private String ip;
private int port;
// ... getter and setters
}
}
本质是生成json进行提示：
