修正思路:不让openfire的pluginServlet自动加载类springmvc的DispatcherServlet改成在插件初始化的时候手动将DispatcherServlet注册到PluginServlet中.
1.web-custom.xml不定义DispatcherServlet.
2.自定义一个CustomDispatcherServlet,继承DispatcherServlet,在其构造方法中指定springMvc的配置文件路径,并且修改 配置文件中velocityConfigurer节点下的resourceLoaderPath值.
import java.io.File;import org.springframework.web.servlet.DispatcherServlet;import com.aomaisoft.openfire.plugin.usionmrg.web.tools.XMLEditor;/** * 自定义DispatcherServlet,指定context位置 * * @author 20005 * @createDate 2014-7-14 上午11:10:59 */public class CustomDispatcherServlet extends DispatcherServlet {private static final long serialVersionUID = 5713165491251313468L;public CustomDispatcherServlet() {super();String pluginDir = null;Character fileSep = File.separatorChar;String contextConfigLocation = pluginDir + fileSep + "java" + fileSep+ "PluginServlet-servlet.xml";// 更改模板目录XMLEditor.alterXML(pluginDir, contextConfigLocation);contextConfigLocation = "file:/" + contextConfigLocation;super.setContextConfigLocation(contextConfigLocation);}}
附上XMLEditor代码 ,依赖dom4j.jar,可以到 去下载
import java.io.File;import java.io.FileOutputStream;import java.io.IOException;import java.util.HashMap;import java.util.Map;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.Element;import org.dom4j.io.OutputFormat;import org.dom4j.io.SAXReader;import org.dom4j.io.XMLWriter;/** * xml节点修改 * * @author 20005 * @createDate 2014-7-15 下午04:35:47 */public class XMLEditor {public static Document read(String fileName) {SAXReader reader = new SAXReader();Map<String, String> nsMap = new HashMap<String, String>();nsMap.put("beans", "");reader.getDocumentFactory().setXPathNamespaceURIs(nsMap);reader.setEncoding("UTF-8");Document document = null;try {document = reader.read(new File(fileName));} catch (DocumentException e) {e.printStackTrace();}return document;}public static void alterXML(String newValue, String url) {OutputFormat format = new OutputFormat("\t", true);format.setEncoding("UTF-8");Document document = read(url);Element node = ((Element) document.selectSingleNode("//beans:property[@name='resourceLoaderPath']")).element("value");<span style="white-space:pre"></span>//此处路径要做相应的修改,为你的模板路径String string = "file:/%s\\web\\WEB-INF\\template";string = String.format(string, newValue);node.setText(string);try {// 重新写入到XML文档XMLWriter writer = new XMLWriter(new FileOutputStream(url), format);writer.write(document);writer.close();} catch (IOException e) {e.printStackTrace();}}}3.在插件初始化时手动注册到PluginServlet中@Overridepublic void initializePlugin(PluginManager manager, File pluginDirectory) {// 得到spring mvc配置文件路径,修改成你相应的路径,我是放在web-inf下的File webXML = new File(pluginDirectory.toString() + File.separatorChar+ "web" + File.separatorChar + "WEB-INF" + File.separatorChar+ "springMVC.xml");// 注册servletPluginServlet.registerServlets(manager, this, webXML);}4.完成,测试.
spring配置文件部分代码
<!– 视图解析 –><bean id="viewResolver"class="org.springframework.web.servlet.view.velocity.VelocityViewResolver"><!– 在src目录下新建文件夹template用来存在velocity模板文件 –><property name="prefix" value="/" /><property name="suffix" value=".html" /><property name="contentType" value="text/html;charset=utf-8"></property></bean><bean id="velocityConfigurer"class="org.springframework.web.servlet.view.velocity.VelocityConfigurer"><property name="resourceLoaderPath"><value><!– 先不填,在程序中指定 –></value></property><property name="velocityProperties"><props><prop key="input.encoding">UTF-8</prop><prop key="output.encoding">UTF-8</prop></props></property></bean>
，继续期待我的下一个旅行，拿起背包，
