使用Spring Boot的时候,填写配置信息(application.properties或application.yml)时,会出现提示。这种方式IDE也可以检查配置是否正确,对用户非常友好。本文介绍如何实现自定义配置的提示 添加自定义配置类使用注解@ConfigurationProperties @Component @ConfigurationProperties(prefix = "blog") public class BlogProperty { /** * blog's title */ private String title; private String author; private boolean gender; private String national; } 添加注解处理器为配置类BlogProperty添加注解@ConfigurationProperties后,IDEA会出现红色提示Spring Boot Configuration Annotation Processor not found in classpath,这是因为还需要为注解配置处理器 org.springframework.boot spring-boot-configuration-processor true 编译生成提示文件上一步添加注解处理器后,还是会出现绿色提示 Re-run Spring Boot Configuration Annotation Processor to update generated metadata。该提示只是告诉我们去重新编译Spring Boot这样就可以更新生成的metadata文件,直接隐藏即可 生成的文件如下classes/META-INF/spring-configuration-metadata.json { "groups": [ { "name": "blog", "type": "com.tenmao.property.BlogProperty", "sourceType": "com.tenmao.property.BlogProperty" } ], "properties": [ { "name": "blog.author", "type": "java.lang.String", "sourceType": "com.tenmao.property.BlogProperty" }, { "name": "blog.gender", "type": "java.lang.Boolean", "sourceType": "com.tenmao.property.BlogProperty", "defaultValue": false }, { "name": "blog.national", "type": "java.lang.String", "sourceType": "com.tenmao.property.BlogProperty" }, { "name": "blog.title", "type": "java.lang.String", "description": "blog's title", "sourceType": "com.tenmao.property.BlogProperty" } ], "hints": [] } 很容易明白name, type, sourceType是如何从配置类生成的 其中配置类中的注解会变成json中的description 使用 配置提示 手动修改在自动生成的结果中再进行手动修改,比如为blog.national提供枚举值 "hints": [ { "name": "blog.national", "values": [ { "value": "China", "description": "People's Republic of China" }, { "value": "Japan", "description": "Japan in Asia" } ] } ] 枚举值 误解 很多地方都说需要在Spring Boot启动类上配置@EnableConfigurationProperties:实际上并不需要 参考 https://docs.spring.io/spring-boot/docs/current/reference/html/configuration-metadata.html Re-run Spring Boot Configuration Annotation Processor to update generated metadata |
