Answer 1

您需要使用组件或行为的#renderHead() 方法。阅读 https://ci.apache.org/projects/wicket/guide/7.x/single.html#_adding_resources_to_page_header_section 了解更多信息。

public class MyComponent extends Component{

    @Override
    public void renderHead(IHeaderResponse response) {
       String json = ...;
       response.render(JavaScriptHeaderItem.forScript(json));
    }
}

//We need to call a fetch function in the script tags fam

<script>
  fetch('localhost:8080/getMyJson', (res, err) => { 
    err ? console.err(err) : console.log(res) 
  })
</script>

// the default HTTP method is set as GET
