java - JBoss 上下文参数

Question

我有一个简单的 Servlet，它“提供”一个简单的 XML 文件；它将从文件中动态加载。在 tomcat 中我使用了上下文参数，在 JBoss 中我该怎么做？

代码:

resp.setContentType("text/xml");
// String path = System.getProperty("AnagraficaXML");
String path = getServletContext().getInitParameter("AnagraficaXML");
// InputStream is = ClassLoader.getSystemResourceAsStream(XML_FILE);
File file = new File(path);
FileReader fileReader = new FileReader(file);
BufferedReader br = new BufferedReader(fileReader);
PrintWriter out = resp.getWriter();
String line = br.readLine();
while (line != null) {
    out.append(line);
    line = br.readLine();
}
br.close();
fileReader.close();

Tomcat 配置(文件 server.xml)

<Context docBase="AnagraficaCedacri" path="/AnagraficaCedacri"
    reloadable="true" source="org.eclipse.jst.jee.server:AnagraficaCedacri">
    <Parameter name="AnagraficaXML" value="D:\Dvlpmnts\Cedacri\CedacriServerResources\Anagrafica.xml"
        override="false" />
</Context>

我会在这里找到一个可以在 Tomcat/Jboss 和 WebSpe 中工作的“可移植”解决方案!

您需要创建一个 Java 网络应用程序 (WAR) 并将其放在部署文件夹中。

@WebServlet("/AnagraficaCedacri")
public class HelloWorldServlet extends HttpServlet {

   protected void doGet(HttpServletRequest req, HttpServletResponse resp)
         throws ServletException, IOException {

      resp.setContentType("text/xml");
      // String path = System.getProperty("AnagraficaXML");
      String path = getServletContext().getInitParameter("AnagraficaXML");
      // InputStream is = ClassLoader.getSystemResourceAsStream(XML_FILE);
      File file = new File(path);
      FileReader fileReader = new FileReader(file);
      BufferedReader br = new BufferedReader(fileReader);
      PrintWriter out = resp.getWriter();
      String line = br.readLine();
      while (line != null) {
         out.append(line);
         line = br.readLine();
      }
      br.close();
      fileReader.close();    
   }
}
