Java 使用ajax jquery Struts-1设置Action类属性

我在通过ajax调用设置action类字符串时遇到了一个问题。这是我的密码

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调用如下所示：

<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>

var testString=“testName”；
$.ajax({
url:“${pageContext.request.contextPath}/gettransactionData.do？参数=getTransactionsByStatus”，
键入：“POST”，
数据：“testString=”+testString，
数据类型：“json”，
成功：功能（数据）
{       
str=数据；
},
async:false，
错误：函数（XMLHttpRequest、textStatus、errorshown）{
警报（“错误”+文本状态）；
警报（错误抛出）；
警报（XMLHttpRequest.responseText）；
}
});

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action调用时，我得到的testString为null。我已经尽了最大的努力去解决它，但是找不到缺少的东西。非常感谢您的帮助。

为您的ActionForm类定义一个

 public class Person extends ActionForm {

        private String testString;

        public String getTestString() {
            return testString;
        }

        public void setTestString(String testString) {
            this.testString = testString;
        }



    }

您的Struts配置将如下所示

   <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>

检查这些更改，希望它能起作用

定义ActionForm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配置将如下所示

   <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>

您在哪里定义了ActionForm？我想您是将testString作为帖子主体提交的？但是我看不到您的Actionform定义，其中action将填充此值。您在哪里定义了Actionform？我猜您是将testString作为帖子主体提交的？但我看不到您的Actionform定义，其中action将填充此值
