使用@configurationProperties注解时 idea弹出 Spring Boot Annotion processor not found in classpath

转自：https://www.jianshu.com/p/e99bda52f878

1.首先增加pom文件的spring-boot-configuration-processor依赖

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency>

2.在需要使用自定义属性的类上增加@ConfigurationProperties(prefix = "xxx")的注解

@ConfigurationProperties(prefix = "person") public class Person { }

3.在启动类增加@EnableConfigurationProperties注解

@SpringBootApplication @EnableConfigurationProperties public class SpringBootYamlConfigApplication { public static void main(String[] args) { SpringApplication.run(SpringBootYamlConfigApplication.class, args); } }

4. 如果resources文件夹下没有application.yaml的话新建下，之后就可以使用idea的提示
