Question

我正在做一个关于Spring和YUI数据表的项目。

我使用controller返回JSON字符串，在视图中将使用JSON字符串作为数据源来生成数据表。但不知何故，数据表显示“数据错误”。

以下是控制器的代码：

@RequestMapping（value =“/ report”） public ModelAndView getViolationReport（Long violation_num）{

        ComplLog origViolation = null;
        //HashMap<Long, BRMap> logdetailsmap = new HashMap<Long, BRMap>();

        Map<String,String> map = new HashMap<String, String>();

        map.put("col1", "value1");
        map.put("col2", "value2");
        map.put("col3", "value3");
        map.put("col4", "value4");
        map.put("col5", "value5");

        List<Map<String,String>> list = new ArrayList<Map<String,String>>();
        list.add(map);

        ModelAndView mav = new ModelAndView();

        mav.addObject("detailList", list);
        mav.setViewName("GetViolationReport");      //return the model to the GetViolationReport.jsp          
        return mav;
}

这是我的index.jsp文件：

<% response.sendRedirect("/app/ViolationReportService.app"); %>

以下是我的观点，GetViolationReport.jsp：

<body class="yui-skin-sam" topmargin="0" leftmargin="0" marginheight="0" marginwidth="0">
<div id="scroller" class="scrollPane">
    <c:out value = "${detailList}" />    
</div>
<div id="basic"></div> 
</body>
<script type="text/javascript">
YAHOO.util.Event.addListener(window, "load", function() {
YAHOO.example.Basic = function() {
    var myColumnDefs = [
        {key:"col1", sortable:true, resizeable:true},
        {key:"col2", sortable:true, resizeable:true},
        {key:"col3", sortable:true, resizeable:true},
        {key:"col4", sortable:true, resizeable:true},
        {key:"col5", sortable:true, resizeable:true}

    ];
 var myDataSource = new YAHOO.util.XHRDataSource("app/violationreport/report");
    myDataSource.responseType = YAHOO.util.XHRDataSource.TYPE_JSON;
    myDataSource.responseSchema = {
        metaFields : {
            totalRecords : "detailmap.totalRecordsFound",
            recordsReturned : "detailmap.totalRecordsFound",
            invocationStatus : "invocationStatus",
            startIndex : 0,
            executionStatusMessage : "executionStatusMessage"
        },
        resultsList : "detailList",
        fields : [ "col1","col2","col3","col4","col5" ] 
    }
var myDataTable = new YAHOO.widget.DataTable("basic",
            myColumnDefs, myDataSource, {initialLoad: true, caption:"DataTable Caption"});

    return {
        oDS: myDataSource,
        oDT: myDataTable
    };
 }();
});
</script>

actoolkit-config.xml是这样的：

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="favorParameter" value="true" /> 
    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json" /> 
            <entry key="html" value="text/html" /> 
            <entry key="plain" value="text/plain" /> 
            <entry key="octet" value="application/octet-stream" /> 
        </map>
    </property>
    <property name="viewResolvers">
        <list>
            <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
            <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
                <property name="viewClass"
                    value="org.springframework.web.servlet.view.JstlView" />
                <property name="prefix" value="/WEB-INF/jsp/" />
                <property name="suffix" value=".jsp" />
            </bean>
        </list>
    </property>

    <property name="defaultViews">
        <list>
            <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />                   
        </list>
    </property>
    <property name="defaultContentType" value="application/json" /> 
</bean>

控制台中没有错误，但是当我转到应该生成数据表的URL时，它显示了一个数据表，其中包含我定义的列，但内容显示“数据错误”。

有人可以帮帮我吗？

数据实际上是什么样的？浏览器接收的内容是什么？我不理解您的非JavaScript代码，即使我这样做，有时会发生代码中存在一些错误，并且服务器抛出了客户端无法解析的错误消息。因此，在浏览器中打开调试器并查看浏览器实际获得的内容。
