com.jfinal.render.VelocityRender static void init(ServletContext servletContext) { String webPath = servletContext.getRealPath("/"); properties.setProperty(Velocity.FILE_RESOURCE_LOADER_PATH, webPath); properties.setProperty(Velocity.ENCODING_DEFAULT, getEncoding()); properties.setProperty(Velocity.INPUT_ENCODING, getEncoding()); properties.setProperty(Velocity.OUTPUT_ENCODING, getEncoding()); } 此方法中,servletContext.getRealPath("/")为获取绝对路径,但weblogic中部署,该值的获取为空,会导致系统报错。
