Unable to evaluate Map as Context

[tarkal]

I need to be able to use this with a context that is a Map<String, Object>. The context is created at run time so I cant define it as a POJO. Unfortunately the library currently doesn't seem to be able to handle a Map context. The output file seems to just skip over every single placeholder.

The test context I'm passing in looks like this in JSON:

{
   "iterator": {
      "name":"John Doe"
   }
}

I have tried the following placeholders but none work:

${iterator.name}
${iterator['name']}
${['iterator']['name']}
${['iterator'].['name']}

Any suggestions?

OK this not a fix but it is a workaround until this issue is resolved. You can create a POJO that has a single property of type Map<String, Object> then it seems to work. I created a property called ctx and then it works with this:

${ctx['iterator']['name']}

FYI, you can have a Map as a context and make spel evaluate it by configurating the EvaluationContext thusly:

DocxStamperConfiguration config = new DocxStamperConfiguration();
config.setEvaluationContextConfigurer(ctx -> ctx.addPropertyAccessor(new MapAccessor()));
DocxStamper<Map<String, Object>> stamper = new DocxStamper<>(config);
stamper.stamp(/*template*/, /*data map*/, /*output*/);

You should at least be able to have this in the word template

${iterator['name']}

Where does MapAccessor() come from?

From org.springframework.context.expression
It's the package that helps support the 'Spel' Spring expression language.

Amazing, it wasn't imported with docx-stamper. For anyone else you can get it here:

<dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-context</artifactId>
     <version>${springVersion}</version>
</dependency>
