springboot啟動時自動加載application.properties或者application.yml，如何定義自己的配置讓springboot自動識別：
首先我們新建一個maven工程打包方式選擇jar，然后引入所需的包
<?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>2.1.6.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
<groupId>com.ruobbo.xxl</groupId>
<artifactId>ruobbo.xxl</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<properties>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<version>2.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>2.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<version>2.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.8</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.xuxueli</groupId>
<artifactId>xxl-job-core</artifactId>
<version>2.0.1</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
</dependency>
</dependencies>
<!-- 項目部署配置 (上傳到私服的配置) -->
<distributionManagement>
<repository>
<id>releases</id>
<url>http://192.168.1.99:8081/nexus/content/repositories/releases</url>
</repository>
<snapshotRepository>
<id>snapshots</id>
<url>http://192.168.1.99:8081/nexus/content/repositories/snapshots</url>
</snapshotRepository>
</distributionManagement>
</project>
然后是配置讀取
@ConfigurationProperties(prefix = "xxl.job.executor")
@Data
public class XxlProperties {
private String adminAddresses;
private String appName;
private String ip;
private int port;
private String accessToken;
private String logPath;
private int logRetentionDays;
private String basePackages;
}
將讀取到的配置注入到bean中，然后加載到spring bean容器中
@Configuration
@EnableConfigurationProperties(XxlProperties.class)
public class XxlAutoConfiguration {
private Logger logger = LoggerFactory.getLogger(XxlAutoConfiguration.class);
@Resource
private XxlProperties xxlProperties;
@Bean(initMethod = "start", destroyMethod = "destroy")
public XxlJobSpringExecutor xxlJobExecutor() {
logger.info(">>>>>>>>>>> xxl-job config init.");
XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
xxlJobSpringExecutor.setAdminAddresses(xxlProperties.getAdminAddresses());
xxlJobSpringExecutor.setAppName(xxlProperties.getAppName());
xxlJobSpringExecutor.setIp(xxlProperties.getIp());
xxlJobSpringExecutor.setPort(xxlProperties.getPort());
xxlJobSpringExecutor.setAccessToken(xxlProperties.getAccessToken());
xxlJobSpringExecutor.setLogPath(xxlProperties.getLogPath());
xxlJobSpringExecutor.setLogRetentionDays(xxlProperties.getLogRetentionDays());
return xxlJobSpringExecutor;
}
}
最后在resources目錄下添加META-INF文件夾添加spring.factories文件，文件內容為指定要初始化springbean的類全路徑
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\com.ruobbo.xxl.XxlAutoConfiguration
使用過程中引入包
<dependency>
<groupId>com.ruobbo.xxl</groupId>
<artifactId>ruobbo.xxl</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
然后添加配置到application.properties或者application.yml
