使用Ajax jquery struts-1设置动作类属性

Question

我在通过ajax呼叫设置动作类字符串时面临问题。这是我的代码

dashboardgraphaction.java

public class DashBoardGraphAction extends DispatchAction
{
   private String testString;

   public ActionForward getTransactionsByStatus(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
                    throws Exception
    {   
       System.out.println(fromDate);
       return null;
     }
    public String getTestString() {
        return testString;
    }  
    public void setTestString(String testString) {
        this.testString = testString;
    }

ajax调用如下：

<script>
            var testString = "testName";
            $.ajax({
                url: '${pageContext.request.contextPath}/gettransactionData.do?parameter=getTransactionsByStatus',
                type: 'POST',
                data: 'testString='+testString,
                dataType: 'json',
                success: function(data)
                {       
                    str = data;
                },
                async:false,
                error: function(XMLHttpRequest, textStatus, errorThrown){
                alert('Error ' + textStatus);
                alert(errorThrown);
                alert(XMLHttpRequest.responseText);
                }
            });
 </script>

struts-config.xml

<action path="/gettransactionData" parameter="parameter"
    type="com.pp.dashboard.DashBoardGraphAction">
    <forward name = "getTransactionsByStatus" path = "/jsp/pp/dashboardReportStatus.jsp" /> 
    <forward name = "getTransactionsByProcessor" path = "/jsp/pp/dashboardReportProcessorWise.jsp" />
</action>

当动作调用时，我将测试标记为null。我已经尽力解决它，但找不到缺少的东西。任何人都非常感谢。

定义您的动作形式类

 public class Person extends ActionForm {
        private String testString;
        public String getTestString() {
            return testString;
        }
        public void setTestString(String testString) {
            this.testString = testString;
        }

    }

您的Struts配置看起来像这样

   <struts-config>
         <form-beans>
            <form-bean name="formClass" type="com.forms.Person"/>
        </form-beans>
        <action-mappings>

            <action name="formClass" path="/gettransactionData" parameter="parameter"
    type="com.pp.dashboard.DashBoardGraphAction">
    <forward name = "getTransactionsByStatus" path = "/jsp/pp/dashboardReportStatus.jsp" /> 
    <forward name = "getTransactionsByProcessor" path = "/jsp/pp/dashboardReportProcessorWise.jsp" />
</action>

        </action-mappings>
    </struts-config>

更改类似的动作类方法

public ActionForward getTransactionsByStatus(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
                    throws Exception
    {   
       Person p = (Person) form;
       System.out.println("Testing************************"+p.getTestString());
       return null;
     }

希望使用这些更改检查它将起作用
