我看这里的步骤进行集成:
https://github.com/nutzam/nutzmore/tree/master/nutz-plugins-views
MainModule:
@Modules(scanPackage = true)
@SetupBy(MySetup.class)
@Encoding(input = "UTF-8", output = "UTF-8")
@IocBy(type = ComboIocProvider.class,
args = {"*js", "ioc/", "*anno", "com.dd","*org.nutz.plugins.view.freemarker.FreemarkerIocLoader"})
//@Views(DDView.class)
@Views(FreemarkerViewMaker.class)
@Fail("json")
public class MainModule {
}
controller:
@At
@Ok("fm")
public Object hello(){
return new NutMap().setv("hello","world");
}
报错了:

报错代码为:
private String getPath(String path) {
StringBuffer sb = new StringBuffer();
// 空路径，采用默认规则
if (Strings.isBlank(path)) {
sb.append(Mvcs.getServletContext().getRealPath(freeMarkerConfigurer.getPrefix()));
sb.append((path.startsWith("/") ? "" : "/")); //这里抛出空指针
sb.append(Files.renameSuffix(path, getExt()));
}
// 绝对路径 : 以 '/' 开头的路径不增加 '/WEB-INF'
else if (path.charAt(0) == '/') {
String ext = getExt();
sb.append(path);
if (!path.toLowerCase().endsWith(ext))
sb.append(ext);
}
// 包名形式的路径
else {
sb.append(path.replace('.', '/'));
sb.append(getExt());
}
return sb.toString();
}
