我正在嘗試創建一個自定義類型轉換器,以便將對象集合從一個字符串中來回轉換。我的表單中有一個文本區域,並且希望在保存的文本區域中爲每個換行符在集合中創建一個新對象。在顯示信息時,我想遍歷集合中的對象,並將其轉換爲帶有換行符的字符串以顯示我的文本區域。到目前爲止,我甚至無法根據我所擁有的註釋讓我的轉換器觸發或接收任何類型的錯誤。下面是我的類定義:Struts 2操作類型使用註釋轉換列表
@Conversion()
public class FormsEdit extends JWebCrud{
這個類裏面我有一個列表:
private List<Formfield> formFields;
的Formnfield類裏面我有一組:
private Set<Formfieldopts> formfieldoptses = new HashSet<Formfieldopts>(0);
@TypeConversion(converter = "com.webexchange.actions.tpa.setup.forms.FormFieldOptsConverter")
public void setFormfieldoptses(Set<Formfieldopts> formfieldoptses) {
this.formfieldoptses = formfieldoptses;
}
是否有人可以直接我如何正確設置這些註釋以使Converter能夠觸發?
Struts 2的版本: 2.2.1

S2版本?動作/攔截器堆棧配置?有關掃描或轉換過程的任何關於DEBUG/devMode日誌級別的信息? –
S2版本:2.2.1 –
我在devMode中擁有Struts 2配置。我也爲根記錄器開啓了DEBUG。但是,我沒有看到Struts輸出任何東西。 –
