当前版本`beetl-core-3.19.1.RELEASE.jar` ## 【疑问】在定界符里输出定界符 有个场景，实现一个代码生成模版功能，输出的模版继续使用beetl渲染。 ``` //获取模板 String temp= """ <% var map={}; map['a']=1; map['b']=2; %> ${map} 输出定界符到新模版，这样调用会报错 <% print("<% for(item in list){ %>") %> """; Template t = gt.getTemplate(temp); //渲染结果 String str = t.render(); System.out.println(str); ``` 报错代码：`<% print("<% for(item in list){ %>") %>` ## 个人解决方案 注册一个自己方法输出 ``` // 后台代码 public String outToken(){ return "<%"; } // 模版使用 <% print(myFun.outToken()+" for(item in list){ "+myFun.outTokenEnd()) %> // 输出 <% for(item in list){ %> ``` ## 请教 如何在定界符中输出定界符，使用`\`无法转义，如果没有专门的方案，可能得使用上面中转输出的方案了。 输出占位符很好兼容： `<% print("${myVal}") %>`
