springboot自定义stater启动流程

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

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

org.springframework.boot

spring-boot-starter-parent

2.1.6.RELEASE

com.ruobbo.xxl

ruobbo.xxl

0.0.1-SNAPSHOT

jar

1.8

org.springframework.boot

spring-boot-starter

2.1.6.RELEASE

org.springframework.boot

spring-boot-autoconfigure

2.1.6.RELEASE

org.springframework.boot

spring-boot-configuration-processor

2.1.6.RELEASE

org.projectlombok

lombok

1.18.8

provided

com.xuxueli

xxl-job-core

2.0.1

org.springframework.boot

spring-boot-starter-test

test

org.junit.vintage

junit-vintage-engine

releases

http://192.168.1.99:8081/nexus/content/repositories/releases

snapshots

http://192.168.1.99:8081/nexus/content/repositories/snapshots

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

org.springframework.boot

spring-boot-starter-parent

2.1.6.RELEASE

com.ruobbo.xxl

ruobbo.xxl

0.0.1-SNAPSHOT

jar

1.8

org.springframework.boot

spring-boot-starter

2.1.6.RELEASE

org.springframework.boot

spring-boot-autoconfigure

2.1.6.RELEASE

org.springframework.boot

spring-boot-configuration-processor

2.1.6.RELEASE

org.projectlombok

lombok

1.18.8

com.xuxueli

xxl-job-core

2.0.1

org.springframework.boot

spring-boot-starter-test

test

org.junit.vintage

junit-vintage-engine

releases

http://192.168.1.99:8081/nexus/content/repositories/releases

snapshots

http://192.168.1.99:8081/nexus/content/repositories/snapshots

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

@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

com.ruobbo.xxl

ruobbo.xxl

0.0.1-SNAPSHOT

然后添加配置到application.properties或者application.yml
