Freemarker无法访问对象字段

Question

I am struggling with a Freemarker weird issue.

<#list fieldMap?keys as key> 
    ${fieldMap[key]}

    ${fieldMap[key].name}

</#list> 

The console is

    GeneratorField{name=expenseType, fieldType=String}

    FreeMarker template error:
The following has evaluated to null or missing:
==> fieldMap[key].name  [in template "ftl/form.ftl" at line 6, column 7]

As you can see, the first line is outputting the name of GeneratorField object, but why the second command failed ?

I am using Freemarker 2.3.20

Thanks

Answer 1

If fieldMap is a class in JAVA then there will be getters in that JAVA class to expose the field name for access, ie, you can create a public function called getName() in that class and then access the same function in your ftl file.

Hope it helps.
