Velocity加載classpath下模板

Velocity默認是加載文件系統中的模板，如果希望加載classpath下的模板的話，需要更換他的加載器

 Properties properties=new Properties();
	        //設置velocity資源加載方式爲class
 properties.setProperty("resource.loader", "class");
	        //設置velocity資源加載方式爲file時的處理類
 properties.setProperty("class.resource.loader.class", 
                        "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
VelocityEngine ve = new VelocityEngine(properties);   

 

 

默認情況是加載文件系統

        VelocityEngine ve = new VelocityEngine();  
        //設置參數
        ve.setProperty(Velocity.FILE_RESOURCE_LOADER_PATH, templatepath);//加載文件系統

 

另附完整代碼

 Properties properties=new Properties();
	        //設置velocity資源加載方式爲class
	     properties.setProperty("resource.loader", "class");
	        //設置velocity資源加載方式爲file時的處理類
	     properties.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
	        
        VelocityEngine ve = new VelocityEngine(properties);   
        //設置參數
      //  ve.setProperty(Velocity.FILE_RESOURCE_LOADER_PATH, templatepath);
        //處理中文問題
        ve.setProperty(Velocity.INPUT_ENCODING,"utf-8");
        ve.setProperty(Velocity.OUTPUT_ENCODING,"utf-8");
        try  {
            //初始化模板
            ve.init();
            //Velocity模板的名稱 
            Template template = ve.getTemplate(templatename,"utf-8"); 
            Writer mywriter = new PrintWriter(outfile,"utf-8");
            template.merge(vc, mywriter);
            mywriter.flush();           
            mywriter.close();
        } catch (Exception e) {
            e.printStackTrace();
            logger.error("寫模板文件"+templatename+"失敗", e);
            throw e;
        }
