我正在尝试使以前的开发人员编写的一些代码正常工作。是的，他现在离开了公司。:-(

我有一个从 JS 代码进行的 JSON RPC 调用。JS 运行良好，回调方法返回一个对象（不是错误对象）。

但是 Java 类上的方法永远不会受到影响。smd 方法确实受到了打击。

public String smd()
{
   return SUCCESS; // break point reaches here
}

@SMDMethod
public void updateRowValueForField(String key, String value, String fieldname)
{
   // We never get into this method.
}

<package name="EntryBarRPC" namespace="/" extends="star-default">

    <action name="ebToggleSelection" class="eboggleSelectionAction" method="smd">
        <interceptor-ref name="jsonStack">
            <param name="enableSMD">true</param>
        </interceptor-ref>
        <result type="json">
            <param name="enableSMD">true</param>
        </result>
    </action>
</package>

我不知道为什么，或者我错过了什么。我一遍又一遍地阅读JSON 插件页面。

我想我只需要另一双眼睛。

注意：Tomcat 控制台中没有错误，没有 JS 错误。

有人有任何线索吗？干杯杰夫波特

You forgot to include the javascript code. From the example:

<s:url id="smdUrl" namespace="/nodecorate" action="SMDAction" />
<script type="text/javascript">
    //load dojo RPC
    dojo.require("dojo.rpc.*");

    //create service object(proxy) using SMD (generated by the json result)
    var service = new dojo.rpc.JsonService("${smdUrl}");

    //function called when remote method returns
    var callback = function(bean) {
        alert("Price for " + bean.type + " is " + bean.price);
    };

    //parameter
    var bean = {type: "Mocca"};

    //execute remote method
    var defered = service.doSomething(bean, 5);

    //attach callback to defered object
    defered.addCallback(callback);
</script>

Are you sure you call service.updateRowValueForField(key, value, fieldname) and not something different?

Further, your method returns a void (e.g. doesn't return anything). What did you expect to get?

I'm guessing that you need to update the smd() method to actually call updateRowValueForField() rather than simply return immediately. Looks like the previous developer never actually hooked up the methods.
