一、Spring boot自定义配置实现自动提示

@ConfigurationProperties 的作用: 让JavaBean中属性值要和配置文件进行映射

@Getter
@Setter
@ConfigurationProperties(prefix = "jwt")
public class JwtProperties {/*** JWT加解密使用的密钥*/private String secret;/*** JWT的过期限时间*/private String expiration;/*** JWT负载中拿到开头*/private String tokenHead;/*** JWT存储的请求头*/private String tokenHeader;}

二、在启动类中加入@EnableConfigurationProperties 注解

@EnableConfigurationProperties 注解的作用：让使用了 @ConfigurationProperties 注解的类生效。

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

三、idea中会提示SpringBoot Configuration Annotation Processor not configured的错误

四、解决方法

您在使用@ConfigurationProperties注解时可以使用spring-boot-configuration-processor jar 轻松地从带有注释的项目中生成自己的配置元数据文件。该jar包含一个Java注释处理器，在您的项目被编译时会被调用。要使用处理器，请包含对的依赖spring-boot-configuration-processor。

1.添加spring-boot-configuration-processor的依赖

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

重新buil了项目，你会发现问题还没有解决，idea还是提示：SpringBoot Configuration Annotation Processor not configured的错误。

2.在maven-compiler-plugin内的annotationProcessorPaths中添加相应path

<pluginManagement><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.8.1</version><configuration><source>1.8</source><target>1.8</target><encoding>UTF-8</encoding><annotationProcessorPaths><path><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><version>${springboot.version}</version></path></annotationProcessorPaths></configuration></plugin></plugins>
</pluginManagement>

3.maven-clean 重新build一下项目,会在target->classes->META-INF目录下生成配置元数据文件:spring-configuration-metadata.json

打开spring-configuration-metadata.json文件

{"groups": [{"name": "jwt","type": "com.seadog.common.security.config.JwtProperties","sourceType": "com.seadog.common.security.config.JwtProperties"}],"properties": [{"name": "jwt.expiration","type": "java.lang.String","description": "JWT的过期限时间","sourceType": "com.seadog.common.security.config.JwtProperties"},{"name": "jwt.secret","type": "java.lang.String","description": "JWT加解密使用的密钥","sourceType": "com.seadog.common.security.config.JwtProperties"},{"name": "jwt.token-head","type": "java.lang.String","description": "JWT负载中拿到开头","sourceType": "com.seadog.common.security.config.JwtProperties"},{"name": "jwt.token-header","type": "java.lang.String","description": "JWT存储的请求头","sourceType": "com.seadog.common.security.config.JwtProperties"}],"hints": []
}

4.在application.yml中测试
