Coldfusion RESTful webservice：对象不是声明类的实例 [英] Coldfusion RESTful webservice: Object is not an instance of declaring class

问题描述

当我调用URL http://192.168.2.26:8080/rest/RestSample/season/1.json 时出现错误：

错误，ajp-bio-8012-exec-4，03/01/13，16:51:58 RestSample，对象不是声明类的实例包含或处理的文件的特定顺序是：C：\path_to\api\service.cfc''

这是 /api/service.cfc 文件：

 < cfscript> 
组件restpath =seasonrest =true
 {
 
远程查询函数getSeasonsByUserId（numeric userid restargsource =Path）httpmethod =GETrestpath ={ userid}
 {
 var response =; 
 var qry = new Query（）; 
 var userQry =; 
 
 qry.setSQl（select * from mytable where userID =：userid）; 
 qry.addParam（name =userid，value =＃arguments.userid＃，cfsqltype =cf_sql_numeric）; 
 userQry = qry.execute（）。getResult（）; 
 
 if（userQry.recordcount == 0）
 {
 response = userQry; 
} else {
 throw（type =Restsample.SeasonsNotFoundError，errorCode ='404'，detail ='Seasons not found'）; 
} 
 
返回响应; 
} 
} 
< / cfscript> 
  

编辑＃1 ：本教程后：
http://www.anujgakhar.com/2012/ 02/20 / use-rest-services-in-coldfusion-10 /

编辑＃2 ：my application.cfc

 < cfscript> 
 component output =false
 {
 this.name =RestSample; 
 this.applicationTimeout = createTimespan（0,0,0,0）; 
 this.datasource =mydsn; 
 this.username =; 
 this.password =; 
 
 //this.restsettings.skipCFCWithError = true; 
 
 public boolean function onRequestStart（）
 {
 restInitApplication（getDirectoryFromPath（getCurrentTemplatePath（）），this.name）; 
 
 return true; 
} 
} 
< / cfscript> 
  

还要注意，在管理中刷新REST服务ALWAYS给我以下消息： p>

 无法刷新REST服务。 
无法初始化应用程序RestSample。 
原因：应用程序不包含任何已启用的CFC。 
应用程序不包含任何已启用的CFC。但是，我可以删除它们，并通过onRequestStart（）添加它们，没有任何问题。

我目前的结构
 
 
 
 /api/main/service.cfc 
 /api/application.cfc 
 /api/index.cfm 
 
 
 
应用程式。 cfc 
 < cfscript> 
 component output =false
 {
 this.name =RestSample; 
 this.applicationTimeout = createTimespan（0,0,0,0）; 
 this.datasource =mydsn; 
 this.username =; 
 this.password =; 
 
 this.restsettings.skipCFCWithError = true; 
 
 public boolean function onRequestStart（）
 {
 restInitApplication（getDirectoryFromPath（getCurrentTemplatePath（））。concat（main\，this.name）; 
 
 return true; 
} 
} 
< / cfscript> 
  
 service.cfc 
 < cfscript> 
 component restpath =seasonrest =true
 {
 
 remote query function getSeasonsByUserId（numeric userid restargsource =Path）httpmethod =GETrestpath ={ userid}
 {
 var response =; 
 var qry = new Query（）; 
 var userQry =; 
 
 qry.setSQl（select * from mytable where userID =：userid）; 
 qry.addParam（name =userid，value =＃arguments.userid＃，cfsqltype =cf_sql_numeric）; 
 userQry = qry.execute（）。getResult（）; 
 
 return userQry; 
} 
} 
< / cfscript> 
  
我仍然得到以下错误：
 '对象不是声明类
的实例 
 
 
解决方案
我创建了 C：\ColdFusion10\cfusion\root （而不是站点的IIS根目录）通过管理控制台的REST服务没有任何问题。
 
When I call the URL http://192.168.2.26:8080/rest/RestSample/season/1.json I get the error:

  
"Error","ajp-bio-8012-exec-4","03/01/13","16:51:58","RestSample","object is not an instance of declaring class The specific sequence of files included or processed is: C:\path_to\api\service.cfc'' "
This is the /api/service.cfc file:
<cfscript>
component restpath="season" rest="true"
{

    remote query function getSeasonsByUserId(numeric userid restargsource="Path") httpmethod="GET" restpath="{userid}"
    {
        var response = "";
        var qry = new Query();
        var userQry = "";

        qry.setSQl("select * from mytable where userID = :userid");
        qry.addParam(name="userid", value="#arguments.userid#", cfsqltype="cf_sql_numeric");
        userQry = qry.execute().getResult();

        if(userQry.recordcount == 0)
        {
            response = userQry;
        } else {
            throw(type="Restsample.SeasonsNotFoundError", errorCode='404', detail='Seasons not found');
        }

        return response;
    }    
}   
</cfscript>
Edit #1: following this tutorial:
http://www.anujgakhar.com/2012/02/20/using-rest-services-in-coldfusion-10/

Edit #2: my application.cfc
<cfscript>
component output="false"
{
    this.name = "RestSample";
    this.applicationTimeout = createTimespan(0,0,0,0);
    this.datasource = "mydsn";
    this.username = "";
    this.password = "";

    //this.restsettings.skipCFCWithError = true;

    public boolean function onRequestStart()
    {
        restInitApplication(getDirectoryFromPath(getCurrentTemplatePath()), this.name);

        return true;
    }
}
</cfscript>
Also would like to note, refreshing REST services in the admin ALWAYS gives me the following message:
Unable to refresh REST service.
Application RestSample could not be initialized.
Reason: The application does not contain any rest enabled CFCs.
The application does not contain any rest enabled CFCs.
However, I can remove them and add them via the onRequestStart() without any problems.

Edit #3

My current structure

/api/main/service.cfc
/api/application.cfc
/api/index.cfm

application.cfc
<cfscript>
component output="false"
{
    this.name = "RestSample";
    this.applicationTimeout = createTimespan(0,0,0,0);
    this.datasource = "mydsn";
    this.username = "";
    this.password = "";

    this.restsettings.skipCFCWithError = true;

    public boolean function onRequestStart()
    {
        restInitApplication(getDirectoryFromPath(getCurrentTemplatePath()).concat("main\"), this.name);

        return true;
    }
}
</cfscript>
service.cfc
<cfscript>
component restpath="season" rest="true"
{

    remote Query function getSeasonsByUserId(numeric userid restargsource="Path") httpmethod="GET" restpath="{userid}"
    {
        var response = "";
        var qry = new Query();
        var userQry = "";

        qry.setSQl("select * from mytable where userID = :userid");
        qry.addParam(name="userid", value="#arguments.userid#", cfsqltype="cf_sql_numeric");
        userQry = qry.execute().getResult();

        return userQry;
    } 
}   
</cfscript>
I still get the following error:
'object is not an instance of declaring class

解决方案
I created the files under C:\ColdFusion10\cfusion\wwwroot (instead of the site's IIS root) and was able to register the REST service via the administration console without any issue.
