これは JSP の下にあります。
<%!
public PortletURL getActionURL(RenderResponse response, String action) {
PortletURL portleturl = response.createRenderURL();
try {
portleturl.setWindowState(LiferayWindowState.EXCLUSIVE);
portleturl.setParameter("struts_action", "helloForm");
} catch (Exception e) {
e.printStackTrace();
}
return portleturl;
}
%>
<%
PortletURL helloFormssss = getActionURL(renderResponse, "helloForm");
System.out.println("The URL is helloFormssss " + helloFormssss);
%>
この URL を jQuery AJAX に渡す:
function my_button_handler() {
jQuery.ajax({
type: "POST",
url: "helloFormssss",
success: function(msg){
alert( "Data Saved: " + msg );
}
});
}
これは私のActionクラスです
public class Struts2Action extends DefaultActionSupport {
String name = null;
public String getPOPChartData() throws Exception {
// Enter business logic here
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
String name = ParamUtil.getString(request, "namer");
System.out.println("The name is " + name);
PrintWriter writer = response.getWriter();
writer.print("Hi");
return ActionSupport.SUCCESS;
}
}
これはstruts.xml ファイル内にあります。
<action name="helloForm" class="com.robisoft.portlet.struts.action.Struts2Action" method="getPOPChartData">
<result name="input">/WEB-INF/view/index.jsp</result>
<result name="success">/WEB-INF/view/result.jsp</result>
</action>
URLはhelloFormssssです
http://localhost:8086/web/guest/home?p_p_id=HelloStruts_WAR_HelloStrutsportlet_INSTANCE_yip2vomViZSU&p_p_lifecycle=0&p_p_state=exclusive&p_p_mode=view&p_p_col_id=column-1&p_p_col_count=1&_HelloStruts_WAR_HelloStrutsportlet_INSTANCE_yip2vomViZSU_struts_action=helloForm
これは、サーバーコンソール内で発生している例外です
