Question

我已经使用DefaultConfigurationBuilder尝试集成我的属性和xml文件，如下面的代码：

DefaultConfigurationBuilder dcfb = new DefaultConfigurationBuilder();
File file = new File(filePath);
System.out.println(file.getName());
System.out.println(file.getAbsolutePath());
dcfb.setFile(new File(filePath));
config = dcfb.getConfiguration(true);

xml文件如下所示，其中application.properties是属性文件：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <properties fileName="application.properties"/>
</configuration>
<PropertyList>
    <Property>
        <Name>CommandTimeout</Name>
        <Value>60</Value>
        <Description>Setting the timeout(in seconds)</Description>
        <DefaultValue></DefaultValue>
    </Property>
    <Property>
        <Name>Address</Name>
        <Value>${server.IP}</Value>
        <Description>ip:port</Description>
        <DefaultValue></DefaultValue>
    </Property>
</PropertyList>

但是在调用getConfiguration（true）;

时我得到了异常

org.apache.commons.configuration.ConfigurationException:

感谢任何帮助。

尝试在每个Property标记中添加属性config-class，用于指定映射配置的类：

<Property config-class="FullQulifiesNameOfPropertyClass">

使用DefaultConfigurationBuilder时未指定Bean类
