java使用 org.apache.commons.conf…

所需的组件：

commons-collections-3.2.1.jar
commons-configuration-1.6.jar
commons-lang-2.5.jar
xml-apis-1.0.b2.jar
commons-logging-1.1.1.jar

 

配置文件示例：

<?xml version="1.0"encoding="UTF-8"?>

<!--
    Document   :config.xml
    Description:
        全文索引服务配置文件.
-->

<root>
    <!--身份验证服务的WebService访问地址，注意，该地址必须以 ?wsdl 结束 -->
    <!-- 例如：http://localhost:8088/AuthenticationWebService/services/AuthenticationService?wsdl-->
   <AuthenticationWebServiceURL>http://localhost:8088/AuthenticationWebService/services/AuthenticationService?wsdl</AuthenticationWebServiceURL>
</root>

 

java代码示例：

    public static booleanreadAuthenticationWebServiceURL(StringBuilder pURL, ErrInfopErrInfo)
    {
        boolean pFlag =true;
        int pErrPos = 0;
        Throwable throwable =new Throwable();

           //开始读取配置文件
           if (pFlag)

               //装载配置文件
               XMLConfiguration xmlConfiguration=newXMLConfiguration(configFilePath.trim());

               String serverName=null;
