以下是比较 Coldfusion 9.0.1 和 Railo 4.0.2.002
我有以下(截断)作为cfc的初始化
component {
public myComponent function init(
required string inSetting1,
required string inSetting2
) {
return this;
}
}
如果我运行以下命令,那么它会正确调用
objInstance = new myComponent(
inSetting1 = 'xxx',
inSetting2 = 'yyy'
);
但是,我试图在没有所有必需参数的情况下处理请求此对象的错误配置。到目前为止,我得到了以下
try {
// inSetting2 is not defined == will cause error
objInstance = new myComponent(
inSetting1 = 'xxx'
);
} catch (coldfusion.runtime.MissingArgumentException e) {
// This catches the error for CF 9.0.1
} catch (expression e) {
// This catches the error for Railo 4.0.2
debug(e); // get the error dump for stack trace below
}
到目前为止,expression
我已经尝试了以下基于堆栈跟踪的打开无济于事railo.runtime.type.UDFImpl.defineArguments(UDFImpl.java:171)
(这就是我检索 CF9 的特定类型的方式)
- 铁路
- railo.runtime
- railo.runtime.type
- railo.runtime.type.UDFImpl
- railo.runtime.type.UDFImpl.defineArguments
现在,虽然我可以做catch (expression e)
,甚至可以catch (any e)
,但我更希望能够捕获特定错误,原因很简单,因为在我目前正在更新以与 Railo 一起使用的组件中的某些位置,它依赖于能够确定原因无法区分配置错误(缺少参数)和部署错误(缺少模板)。
那么,是否有人知道一种方法,我可以通过该方法使上述 try/catch 看起来专门用于coldfusion.runtime.MissingArgumentException
(或就此而言,一种方法,我可以在尝试调用/运行方法之前检查所需的参数( s) 有问题)
编辑:我忘了包括堆栈跟踪。这是 Railo 堆栈跟踪。我也已经尝试过以下代替expression
The parameter environment to function init is required but was not
passed in. at
