Spring boot 自定義配置實現自動提示
這個是基於IDE來做的，Eclipse的沒有試驗過
1、新建一個配置類(ExampleProperties)
package org.yujuan.springbootlearning.properties; import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; @Data @ConfigurationProperties(prefix = "example") public class ExampleProperties { /**姓名**/ private String name; /**路徑**/ private String path; /**是否開啟*/ private Boolean enable; }
@value 沒有這個作用。2、引入依賴spring-boot-configuration-processor
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.7.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>org.yujuan</groupId> <artifactId>springboot-learning</artifactId> <version>0.0.1-SNAPSHOT</version> <name>springboot-learning</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.8</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <optional>true</optional> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> 3、修改IDE的配置
打開設置頁面，按照箭頭所指示的地方開啟Enable annotation processing
4、重新編譯
會在target目錄下的META_INF 下生成spring-configuration-metadata.json文件，同時在配置文件寫填寫配置時，會自動提示。如下圖：
