Ajax調用產生javax.xml.transform.TransformerException的Struts2動作

我想寫一個從Ajax調用Struts2動作並使用XML取回數據的小例子。當電話執行時，我得到一個javax.xml.transform.TransformerException（如下所示）。最終，我想從Ajax調用返回的數據XML中獲取name屬性。Ajax調用產生javax.xml.transform.TransformerException的Struts2動作

我可能在這裏錯過了一些簡單的東西，但我很遺憾缺少什麼東西。

我從struts.xml的行動：

<action name="AjaxFormSubmit" class="test.FormSubmit" > 
    <result type="xslt"> 
     <param name="exposedValue">fName</param> 
    </result> 
</action>

的Javascript：

$.ajax({ 
    url: "AjaxFormSubmit.action", 
    error: function(data) 
    { 
     alert("error"); 
     alert(data); 
    }, 
    success: function(data) 
    { 
     alert("success"); 
     alert(data); 
    } 
});

我的動作類：

public class FormSubmit extends ActionSupport { 

    public FormSubmit() 
    { 
     System.out.println("in FormSubmit constructor"); 
    } 

    private String fName; 

    public String getFName() { 
     return fName; 
    } 

    public void setFName(String fName) { 
     System.out.println("setting fName: " + fName); 
     this.fName = fName; 
    } 

    public String execute() throws Exception 
    { 
     System.out.println("in execute"); 

     return SUCCESS; 
    } 
}

例外：

現在缺少的是XSL模板，通過錯誤指示：

SEVERE: Unable to render XSLT Template, 'null'

的"xslt" result type docs狀態的「位置」參數定義的模板。

你確實需要一個XSL結果，還是僅僅是XML？你真的在改變它嗎？

其實我是想的XML，但我讀過到目前爲止約XSLTResult的是，你應該使用，如果你想直接和XML其默認行爲是將整個bean序列化爲XML，並且不需要轉換。 – 2012-08-09 18:49:20

@ChrisWilliams可能;雖然我沒有意識到 - 你是從哪裏讀到的？它也可能發生了變化，儘管我不知道你使用的是什麼版本的S2。無論如何，這就是問題所在。 – 2012-08-09 19:18:02

我認爲XSLTResult的實施已更改，現在需要參數location。

但你仍然可以在使用XSL文件下查看生成的XML：

<?xml version="1.0" encoding="UTF-8"?> 
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
     <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/> 
     <xsl:template match="/"> 
      <xsl:copy-of select="*"/> 
     </xsl:template> 
    </xsl:stylesheet>

試試這個，會幫助你在Struts中2.0.14與jsonplugin-0.32.jar。它爲我工作。

的struts.xml：

<struts> 
    <package name="example" extends="json-default"> 
     <action name="HelloWorld" class="example.HelloWorld" > 
      <result type="json" /> 
     </action> 
       <action name="HelloWorld1" class="example.HelloWorld" > 
      <result name="success" >example/HelloWorld.jsp</result> 
     </action> 
    </package> 
</struts>

動作類Helloworld.java：

package prabhakar; 

import glb.DB; 
import java.util.ArrayList; 
import java.util.List; 
import java.util.Map; 

/** 
* Prabhakar 
*/ 
public class HelloWorld { 


    private List<StateMaster> stateList= new ArrayList<StateMaster>(); 
    private List<RegnMaster> regnList= new ArrayList<StateMaster>(); 

    private Integer stateId; 
    public Integer getStateId() 
    { 
    return this.stateId; 
    } 
    public void setStateId(Integer stateId) 
    { 
    this.stateId=stateId; 
    } 
    public List<StateMaster> getStateList() { 
     return stateList; 
    } 

    public void setStateList(List<StateMaster> stateList) { 
     this.stateList = stateList; 
    } 
    public void setRegnList(List<RegnMaster> regnList) { 
     this.regnList = regnList; 
    } 
    public List<RegnMaster> getRegnList() { 
     return regnList; 
    } 

    public String execute() throws Exception { 

     stateList=DB.getStateData()// 
     if(stateId !=null) 
      { 
     regnList=DB.getRegnByStateId(stateId); 
      } 

     //setMessage(getText(MESSAGE)); 
     return "success"; 
    } 

    /** 
    * Provide default valuie for Message property. 
    */ 

}

可以直接調用HelloWorld.action查看JSON數據，否則你可以綁定JSON數據到下面的表單元素。

JSP頁面的helloWorld.jsp：

/* 
    Prabhakar 
    */ 

<%@ page contentType="text/html; charset=UTF-8" %> 

<%@ taglib prefix="s" uri="/struts-tags" %> 
<script> 
<%@include file="../js/jquery-1.7.1.min.js"%> 
</script> 
    <html> 

<!-- JavaScript Plugins --> 
    <script> 
     function getLoad(){ 


     var stateId = $('#state').val(); 

$.getJSON('HelloWorld.action', {'stateId': stateId}, 
    function(data) { 

      var divisionList = (data.regnList); 

       var options = $("#regn"); 
       options.find('option') 
    .remove() 
    .end(); 
    options.append($("<option />").val("-1").text("--Select--")); 
$.each(divisionList, function() { 

    options.append($("<option />").val(this.regnId).text(this.regnName)); 
}); 
    } 
);} 
    </script> 

<!-- jQuery-UI Dependent Scripts --> 

    <body> 
     State List <s:select name="stateId" list="stateList" id="state" listKey="stateId" onchange="getLoad()" listValue="stateName" headerKey="0" headerValue="--select--" /> 
     Regn List <s:select name="regnId" list="regnList" listKey="regnId" id="regn" listValue="regnName" headerKey="0" headerValue="--select--" /> 
    </body> 
</html>

:) :)
