No qualifying bean of type [com.it.service.DeptService] found for dependency
今天出現了這樣一個錯誤,弄了好久,意思就是我的'deptEmpController沒有deptsv依賴,找了好半天,終於找到了原因。
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'deptEmpController': Unsatisfied dependency expressed through field 'deptsv': No qualifying bean of type [com.it.service.DeptService] found for dependency [com.it.service.DeptService]: expected at least 1 bean which qualifies as autowire candidate for this dependency.
Spring管理service(通過xml讀取service,利用反射建立例項),controller的時候,由於Controller裡面注入了service,但實際並沒有找到service的例項化,慢慢找到原來在applicationContext-Service.xml中,沒有配置我所注入service,所以沒有辦法例項化,導致出錯
錯誤的配置(只配置了一個)
applicationContext-Service.xml:
<bean id="empServiceImp" class="com.it.service.imp.EmpServiceImp"></bean>
正確的配置
applicationContext-Service.xml:
<bean id="empServiceImp" class="com.it.service.imp.EmpServiceImp"></bean>
