我有兩個應用程序(比如說ExternalAPP和InternalAPP)在同一個服務器上都有自己的EAR,我使用的是Struts 1.2。這個想法是從InternalAPP調用ExternalAPP的一個jsp文件並用InternalAPP的信息填充它。當外部動作來自struts動作表單不顯示
既然不能訪問從InternalAPP ExternalAPP的ActionForm中,我創建了一個類似的形式(InternalForm),並設置它在請求屬性,那麼行動ExternalAPP轉發設置,它被稱爲ExternalForm動作形式:
InternalAPP的代碼:
public final String process(HttpServletRequest request, ActionForm form)
throws Exception {
...
InternalForm myForm = new InternalForm();
myForm.setTo("[email protected]");
myForm.setFrom("[email protected]");
//pass this form to the next action in json form
ObjectMapper mapper = new ObjectMapper();
String myFormToJson = mapper.writeValueAsString(myForm);
request.setAttribute("myForm", myFormToJson);
return "forwardExternalAction";
}
InternalAPP的struts-config.xml中
<global-forwards>
....
<forward name="forwardExternalAction" path="/forward/path/externalFormInit.do"/>
</global-forwards>
ExternalAPP代碼:
<action path="/path/externalFormInit" type="com.action.ParseFormAction" >
<forward name="success" path="/externalAction.do" />
</action>
<action path="/externalAction"
type="org.apache.struts.actions.ForwardAction"
name="ExternalForm"
validate="false"
scope="request"
input="/task/myDesiredPage.jsp">
<forward name="success" path="/task/myDesiredPage.jsp" />
<forward name="error" path="/task/myDesiredPage.jsp" />
</action>
ParseFormAction.java
public ActionForward doPerform(ActionMapping mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response) throws Exception {
JSONObject jsonObj = new JSONObject((String) request.getAttribute("myForm"));
ExternalForm myForm = new ExternalForm();
myForm.setTo(jsonObj.getString("to"));
myForm.setFrom(jsonObj.getString("from"));
request.setAttribute("ExternalForm", myForm);
return mapping.findForward("success");
}
myDesiredPage.jsp
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<html>
....
<html:form action="/path/sendOutForm.do" method="POST" >
<div class="form-body">
<div class="frm-row">
<div class="colm6">
<div class="section">
<label class="field prepend-icon">
<html:text property="from" styleClass="gui-input" styleId="fromStyle" disabled="true" />
<span class="field-icon"><i class="fa fa-envelope"></i></span>
</label>
</div><!-- end section -->
<div class="section">
<label class="field prepend-icon">
<html:text property="to" styleClass="gui-input" styleId="toStyle" />
<span class="field-icon"><i class="fa fa-envelope"></i></span>
</label>
</div><!-- end section -->
</div><!-- end .colm6 section -->
</div><!-- end .frm-row section -->
</html:form>
...
</html>
我能到myDesiredPage.jsp從InternalAPP得很好,但它不會填充我發送的信息根據請求,所有值都將爲空。
我錯過了什麼?在調用JSP之前,我在動作類中設置了ExternalAction中的所有值,爲什麼它沒有選擇它們?
如果還有更好的方法來做到這一點,請讓我知道,在我看來,應該有更好的方式來做到這一點。
在此先感謝。
