Junit4测试中，有一些在测试环境无法自动注入的变量怎么解决

[li709854423]

这是我新进一个公司后，在写junit遇到的一个问题。
某个service类{
@Resource
private HttpServletRequest request;
..
}

在junit中。因为就会爆出 request找不到对应的bean错误。
我试过把所有注入request对象的类，注解都去掉。就可以运行junit，但是不能每次都去掉再进行测试吧。。
。
可能重点是我不能理解为什么要注入request吧。做这块的同事已经离职了。。没人问..
不知道怎么处理这个问题

错误如下：

原理...是什么..或者request是在哪里创建的？又怎么给spring管理的。。为什么在正式运行就可以获取到这个bean，而junit4就会出现获取不到bean的原因是什么。。

[今天晴]

request根本就不能注入

[loveunittesting]

你可以用一些mock库来模拟做这些东西

引用 2 楼 TTWiFi 的回复:

request根本就不能注入

@TTWiFi 可是实际运行并没报错。（我也没遇到这样的写法，很郁闷）

[wdd668]

加上@WebAppConfiguration 试下 Try adding @WebAppConfiguration annotation to the test class. Please note, that this option is available only in Spring 3.2+ versions.

也遇到过这种问题，写法项目运行起来不报错，在单元测试报错，查看好像是类的加载顺序问题，我这不多，我把注入方式给换了
