### 2.spring boot 接入 ###

<dependency>
                <groupId>com.ctrip.framework.apollo</groupId>
                <artifactId>apollo-client</artifactId>
                <version>1.1.0</version>
    </dependency>

application.properties

#appId 同来区别不同的配置
    app.id=SampleApp
    #apollo服务器地址
    apollo.meta=http://localhost:8080

代码

package com.example.demo.config;
    
    import com.ctrip.framework.apollo.spring.annotation.EnableApolloConfig;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    @EnableApolloConfig
    public class AppConfig {
        @Bean
        public TestJavaConfigBean javaConfigBean() {
            return new TestJavaConfigBean();
        }
    }

package com.example.demo.config;
    
    import org.springframework.beans.factory.annotation.Value;
    
    public class TestJavaConfigBean {
        @Value("${timeout:100}")
        private int timeout;
        private int batch;
    
        @Value("${batch:200}")
        public void setBatch(int batch) {
            this.batch = batch;
        }
    
        public int getTimeout() {
            return timeout;
        }
    
        public int getBatch() {
            return batch;
        }
    
    }

使用

package com.example.demo.schedule;
    
    import com.example.demo.config.TestJavaConfigBean;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.scheduling.annotation.EnableScheduling;
    import org.springframework.scheduling.annotation.Scheduled;
    import org.springframework.stereotype.Component;
    
    @Component
    @EnableScheduling
    public class ScheduledTest {
    
        @Autowired
        private TestJavaConfigBean testJavaConfigBean;
    
        @Scheduled(cron = "0/5 * * * * ?")
        public void executeFileDownLoadTask() {
            // 间隔2分钟,执行任务
            int timeout = testJavaConfigBean.getTimeout();
            System.out.println("定时任务1:" + timeout);
    
        }
    
    }
