Converter.getAsString介绍

[英]Convert the specified model object value, which is associated with the specified UIComponent, into a String that is suitable for being included in the response generated during the Render Response phase of the request processing lifeycle.
[中]将与指定UIComponent关联的指定模型对象值转换为适合包含在请求处理生命周期的呈现响应阶段生成的响应中的字符串。
