Spring portlet ajax调用，未找到参数

Question

我正在尝试使用 LR 6.2 GA1 构建示例 spring portlet。 以下是同一https://docs.google.com/file/d/0By1kU5o_jlrublhUNXIxQ24wODQ/edit的来源

在 ajax 上没有获取参数。参数始终保持空白。

@Controller(value = "ProjectSearch")
@RequestMapping("VIEW")
public class ProjectSearch {
    Log log_ = LogFactoryUtil.getLog(ProjectSearch.class);

@RenderMapping
public String handleRenderRequest(final RenderRequest request,
        final RenderResponse response, Model model) {
    System.out.println("ProjectSearch.handleRenderRequest()");
    return "search_form";
}

@ResourceMapping("getProjectNameSuggestion")
public void getNameSuggestion(ResourceRequest request,
        ResourceResponse response) throws IOException {
    Map<String, String[]> map = request.getParameterMap();
    for (Map.Entry<String, String[]> element : map.entrySet()) {
        log_.info(element.getKey());
    }
    String entityName = ParamUtil.getString(request, "query");
    log_.info("Entity name==>" + entityName);

}

}
@RenderMapping
    public String handleRenderRequest(final RenderRequest request,
            final RenderResponse response, Model model) {
        System.out.println("ProjectSearch.handleRenderRequest()");
        return "search_form";
    }

@ResourceMapping("getProjectNameSuggestion")
public void getNameSuggestion(ResourceRequest request,
        ResourceResponse response) throws IOException {
    Map<String, String[]> map = request.getParameterMap();
    for (Map.Entry<String, String[]> element : map.entrySet()) {
        log_.info(element.getKey());
    }
    String entityName = ParamUtil.getString(request, "query");
    log_.info("Entity name==>" + entityName);

}

}

输出-->05:23:24,148 INFO [http-bio-8080-exec-119][ProjectSearch:41] Entity name==>

谁能告诉我我做错了什么？？

解决方案：

在 liferay-portlet.xml 中配置要求名称间隔参数为 false

现在需要将 name 间隔参数设置为 false，然后仅将表单数据映射到 Action Request 和 Render Request 中。并且表单数据也将绑定到模型对象或命令对象。

以下是我们需要在liferay-portlet.xml文件中进行的配置

<requires-namespaced-parameters>false</requires-namespaced-parameters>

Liferay 中所需的名称空间参数行为

Liferay 6.2 我们必须为输入元素的每个名称附加 portlet 命名空间，即表单输入元素或请求参数名称，否则 portlet 操作类将忽略没有 portlet 命名空间的参数。

场景

jsp页面

在下面的表单中，我们没有将 portlet 名称空间附加到表单输入元素名称中。

<portlet:actionURL var="addEmployeeActionURL" name="addEmployee">
<portlet:param name="<%=ActionRequest.ACTION_NAME%>" value="addEmployee"/>
</portlet:actionURL>

<form action="<%=addEmployeeActionURL%>" name="emplyeeForm"  method="POST">
Employee Name<br/>
<input  type="text" name="employeeName" id="employeeName"/><br/>
Employee Address<br/>
<input type="text" name="employeeAddress" id="employeeName"/><br/>
<input type="submit" name="addEmployee" id="addEmployee" value="Add Employee"/>
</form>

Portlet Class Action Method

public class EmplyeePortletAction extends MVCPortlet {
public void addEmployee(ActionRequest actionRequest,
ActionResponse actionResponse) throws IOException, PortletException {

String employeeName=ParamUtil.getString(actionRequest,"employeeName");
String employeeAddress=ParamUtil.getString(actionRequest,"employeeAddress");

       }
}

在上述情况下，在 portlet 类操作中无法访问employeeName 和employeeAddress 表单输入数据。表单元素名称未附加portlet 名称空间，此类场景portlet 类忽略那些请求参数或表单输入

解决方案：1

需要将标签附加到每个输入元素名称。

jsp页面

<portlet:actionURL var="addEmployeeActionURL" name="addEmployee">
<portlet:param name="<%=ActionRequest.ACTION_NAME%>" value="addEmployee"/>
<portlet:param name="requestParam" value=" requestParamValue"/>
</portlet:actionURL>

<form action="<%=addEmployeeActionURL%>" name="emplyeeForm"  method="POST">
Employee Name<br/>
<input  type="text" name="<portlet:namespace/>employeeName" id="<portlet:namespace/>employeeName"/><br/>
Employee Address<br/>
<input type="text" name="<portlet:namespace/>employeeAddress" id="<portlet:namespace/>employeeName"/><br/>
<input type="submit" name="addEmployee" id="addEmployee" value="Add Employee"/>
</form>

Portlet 类操作方法

public class EmplyeePortletAction extends MVCPortlet {
public void addEmployee(ActionRequest actionRequest,
ActionResponse actionResponse) throws IOException, PortletException {

String employeeName=ParamUtil.getString(actionRequest,"employeeName");
String employeeAddress=ParamUtil.getString(actionRequest,"employeeAddress");
String requestParamValue=ParamUtil.getString(actionRequest,"requestParam");

       }
}

解决方案：2 我们可以将 liferay-portlet.xml 文件中的标签值设为 false

<requires-namespaced-parameters>false</requires-namespaced-parameters>

解决方案：3

我们可以使用合金标签库表单标签。当我们使用 AUI 标记时，它会将 portlet 名称空间附加到每个输入元素名称。

jsp页面

<%@ taglib uri="http://liferay.com/tld/aui" prefix="aui" %>

<aui:input type="text" name="employeeAddress" id="employeeName"/><br/>
<aui:input type="submit" name="addEmployee" id="addEmployee" value="Add Employee"/




<input type="text" name="<portlet:namespace/>employeeAddress" id="<portlet:namespace/>employeeName"/>

和一样

<aui:input type="text" name="employeeAddress" id="employeeName"/>
