分布式disconf+spring5使用遇到重复加载的问题

            </list>
        </property>
    </bean>

disconf.xml配置如上，没什么大问题，按官方给的demo来好了

配置类如下：

import com.baidu.disconf.client.common.annotations.DisconfFile;
import org.springframework.stereotype.Service;
/**
 * 空的分布式配置文件,用途有两种:<br/>
 * 1. 对配置文件里的内容不感兴趣，只是单纯的下载<br/>
 * 2. 当配置文件更新时，可以自动下载到本地
 */
@Service
@DisconfFile(filename = "activityrule.xml")
public class ActivityRuleConfig {

}

配置类回调加载类

@Service
@DisconfUpdateService(classes = { ActivityRuleConfig.class})
public class ActivityRuleCallBack implements IDisconfUpdate {

    @Override
    public void reload() throws Exception {
        FlowXmlDom.parseXMLData("/activityrule.xml");
    }
}

 

main启动类:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.example.disconf.demo.task.DisconfDemoTask;

/**
 * @author liaoqiqi
 * @version 2014-6-17
 */
public class DisconfDemoMain {

    protected static final Logger LOGGER = LoggerFactory.getLogger(DisconfDemoMain.class);

    private static String[] fn = null;

    // 初始化spring文档
    private static void contextInitialized() {
        fn = new String[] {"applicationContext.xml"};
    }

    /**
     * @param args
     *
     * @throws Exception
     */
    public static void main(String[] args) throws Exception {

        contextInitialized();
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext(fn);

        DisconfDemoTask task = ctx.getBean("disconfDemoTask", DisconfDemoTask.class);

        int ret = task.run();

        System.exit(ret);
    }
}

maven中spring版本使用 

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>RELEASE</version>
</dependency>
最新为5.0版本
启动后总是会报错，目前还是头一次使用spring5遇到问题，

反反复复核对线上文档，发现没有问题

再一次集成到spring-web空项目中，还是一样报错

我把spring的版本换回4.3.13.RELEASE，启动不报错了。

这里先记录下，诸位大神看看是什么问题，目前小弟赶项目进度，没时间研究，放给大家看看
