Groovy和元类 [英] Groovy and the Metaclass
问题描述
我正在尝试使用元类覆盖测试中的静态方法.
I am attempting to use the metaclass to overwrite a static method in a test.
方法是:
org.boon.HTTP.jsonRestCallWithHeaders
这是Java类,超出了我的控制范围.
It it is a Java class, and it is beyond my control.
声明是:
public static Response jsonRestCallWithHeaders(
final String url,
final Map<String, ?> headers
)
我正尝试通过以下方式使用闭包覆盖该方法:
I am attempting to overwrite the method with a closure via:
HTTP.metaClass.static.jsonRestCallWithHeaders = { String url, Map<String, ?> headers ->
if (url.path?.contains('/quotes')) {
[prop1:value1,
prop2: value2 ] as JSON }
但是,当它遇到该重定向请求时,它不会尝试重写该方法.它初始化HTTP类,并尝试调用HTTP.get函数.
However, when it hits that redirect request it doesn't attempt to rewrite the method. It initializes the HTTP class, and attempts to call the HTTP.get function.
我的问题是:为什么对调用HTTP :: get静态方法的jsonRestCallWithHeaders方法的此定义?
My question is: Why is this definition for the jsonRestCallWithHeaders method calling the HTTP::get static method?

我正在使用Groovy 2.1.9,Grails:2.3.8.该代码正在测试环境中运行.

推荐答案
我已经测试了以下内容,并且有效:
I have tested the following and it works:
HTTP.getMetaClass().static.jsonRestCallWithHeaders = { String url, Map<String, ?> headers ->
// ...
}
