为我的弹簧应用程序编写Junit测试。因为我是新手，所以我尝试着写一个我熟知的DAO类的单元测试（在JBoss中运行它）。但是，我无法将它作为Eclipse中的单元测试工作。我一直收到“创建bean时出错...无法自动装入字段：NoSuchBeanDefinition”。自动装配失败，弹簧Junit测试
我在StackOverflow和其他网站上看到类似这样的错误，它总是以语法错误或尝试自动调用接口的实现而不是接口等等。我没有看到任何这些错误用我的代码。
我没有从该项目附带的Spring配置中单独下载Spring-test.jar。两者都是由春2.5然而，所以我不认为这应该是一个问题：/
Eclipse附带使用JUnit 4.8和Spring单元测试捆绑不与，所以我降级我的JUnit使用工作4.4
有一件事要考虑......如果你看看我的单元测试的代码，你会注意到我自动装配了两个字段：我想测试的查询服务中的一个SimpleJdbcTemplate。那么如果我删除DrugDao和所有对它的引用，那么SimpleJdbcQuery自动连线就好了。

我现在就试一试......尽管如此：应该有必要吗？ – IcedDante
Autowire无法找到它，所以添加它或修复组件扫描配置 –
