在单元测试 service 层时出现了 dao 注入失败的原因。

通过异常信息中的 No qualifying bean of type [org.manager.dao.AdminMapper] found for dependency:(找不到名为 AdminMapper 的bean，无法注入 )，得出结论：未能在ServiceTest 中加入 dao 层的 spring 配置文件

解决方法：将

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. @ContextConfiguration({"classpath:spring/spring-dao.xml"})

改为

  1. @RunWith(SpringJUnit4ClassRunner.class)
  2. @ContextConfiguration({"classpath:spring/spring-dao.xml", "classpath:spring/spring-service.xml"})

对Dao层的spring配置文件进行加载即可。
