异常已解决。本人写的博客项目，使用工具类初始化配置进行测试。代码如下:使用加载配置文件生成相应的输入流，使用对象加载输入流工具类初始化配置进行测试。代码如下。

org . c source . common . my exception:null未找到异常中的项目“tracker _ server”已解决。本人写的博客项目，用java工具class A用fastDfs初始化fdfs配置进行了测试，代码如下

class path resource CPR = new class path resource(" fastdfs . properties ")；client global . init(CPR . getclass loader()。getResource("fdfs_client.conf ")。旅游()。getPath())；Properties属性=新属性()；//使用ClassLoader加载属性配置文件生成对应的输入流inputstream in = CPR . getinputstream()；//使用properties对象加载输入流properties . load(in)；ClientGlobal.initByProperties(属性)；tracker group tracker group = client global . g _ tracker _ group；tracker client = new tracker client(tracker group)；b类初始化fdfs配置进行测试，代码如下

私有静态最终字符串CONF _文件名=线程.当前线程()。getContextClassLoader()。getResource("fdfs_client.conf ")。getPath()；-------------------------------------------------client global . init(CONF _文件名)；这两种方法都用于读取配置文件fdfs_client.conf，但它在本地工作，而不是在服务器上(CentOS7.6)。错误内容如下:java.io.file处的Java . lang . nullpointerexception .(file .
