springboot自定义stater启动流程

springboot启动时自动加载application.properties或者application.yml，如何定义自己的配置让springboot自动识别：

首先我们新建一个maven工程打包方式选择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>
 <!-- 项目部署配置 (上传到 * 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>

然后是配置读取

@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;

}

将读取到的配置注入到bean中，然后加载到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目录下添加META-INF文件夹添加spring.factories文件，文件内容为指定要初始化springbean的类全路径

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\com.ruobbo.xxl.XxlAutoConfiguration

使用过程中引入包

  <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
