我使用junit 4.10和mybatis进行了春季3测试的问题。我无法在测试课程中自动提供服务。
这是我得到的例外

我尝试在springBean文件中手动注册bean，但是它获得了一个空值。
我的配置和类是

怎么了？我失去了一些配置吗？ 提前谢谢

感谢大家的回复： - ）

答案 1 :(得分：1)
从
更改自动装配的代码@Autowired
private MailReceiverAccountService mailReceiverAccountService;
到
@Autowired
private DaoService mailReceiverAccountService;
如果您有多个DaoService实现类，请使用@Qualifier和@Autowired来区分它们。
答案 2 :(得分：0)
在上下文xml中，您没有提供用于扫描带注释的组件的基本包。因此，您的服务类不会被扫描和自动装配。请将此条目添加到上下文
中<context:annotation-config />
<context:component-scan base-package="basepackage" />
