FreeMarkerConfigurer配置中{app: "$servlet"}获取异常

积分: 360

这家伙很懒，什么个性签名都没有留下。

boot结合freemaker，template文件都在jar包中，如何正确配置资源路径？

freeMarkerConfigurer: {
        type: "org.nutz.plugins.view.freemarker.FreeMarkerConfigurer",
        events: {
            create: 'init'
        },
        args: [
            {refer: "configuration"},
            {app: "$servlet"},
            "web/view",
            ".ftl",
            {refer: "freemarkerDirectiveFactory"}
        ]
    },

运行起来后，第一次初始化会产生如下异常

main module贴一次看看

七星爆珠(wx_23p8gq8rj75i01c098r7) 4楼•2411天前

@Slf4j
@IocBean
@Views(value = {FreemarkerViewMaker.class})
@At("/s")
public class WebHomeModule {

但这个不是MainModule，我想这个Module有自己的View，所以配置了FreeMaker

七星爆珠(wx_23p8gq8rj75i01c098r7) 5楼•2411天前

@Views({CustomViewMaker.class})
@AdaptBy(type = CustomAdaptor.class)
@At("gameapi")
@Ok("_proto")
@Encoding(input = "UTF-8", output = "UTF-8")
public class MainModule {
}

这个是

没贴全吧？应该有IocBy

七星爆珠(wx_23p8gq8rj75i01c098r7) 7楼•2411天前

用的boot

wendal

8楼•2411天前

噢, 我试一下看看

wendal

9楼•2411天前

试了一下并无报错, 你最初贴的ioc js配置,是自己加的???

七星爆珠(wx_23p8gq8rj75i01c098r7) 10楼•2411天前

配置文件实在https://github.com/nutzam/nutzmore/tree/master/nutz-plugins-views这里copy的

wendal

11楼•2411天前

不需要加的, 自带的 https://github.com/nutzam/nutzboot/tree/dev/nutzboot-demo/nutzboot-demo-simple/nutzboot-demo-simple-freemarker

七星爆珠(wx_23p8gq8rj75i01c098r7) 12楼•2411天前

@Slf4j
@IocBean
@Views({FreemarkerViewMaker.class})
@At("/s")
public class WebHomeModule {
    @Inject
    private FreeMarkerConfigurer freeMarkerConfigurer;

js里去掉了，我希望在WebHomeModule 中引用Configurer对象，以便构建视图

new ViewWrapper(new FreemarkerView(freeMarkerConfigurer, "test"), null);

但是运行起来后会报出来这样的异常

把demo跑起来

只需要加个starter依赖, 其他js/类,统统不需要加的...

七星爆珠(wx_23p8gq8rj75i01c098r7) 15楼•2411天前

搞定了，自己眼花了，因为用了starter同时还引用了plugins-view里面的configurer，传入的对象名字又一样~~~
最后解决方法：
1.用start即可，js不需要配置
2.依赖引用只配置starter即可，引入plugins-view会导致混淆，没有编译错误，但是容易错乱

七星爆珠(wx_23p8gq8rj75i01c098r7) 16楼•2411天前

是的@wendal，已解决，多谢~
