私はこのエラーが発生しており、なぜ私は理解できません。私はその道を信じています。それを何回か変更しようとしましたが、成功しませんでした。

Description: 

Field loginDelegate in com.codeEvaluator.controller.LoginController required a bean of type 'com.codeEvaluator.delegate.LoginDelegate' that could not be found. 


Action: 

Consider defining a bean of type 'com.codeEvaluator.delegate.LoginDelegate' in your configuration. 


Process finished with exit code 1 

これは私のsprinBeanConfiguration.xml

Answer 1

変更

<context:component-scan base-package="com.jcg, com.codeEvaluator" /> 

へとインポートは、これらのアノテーションを追加するには、 "sprinBeanConfiguration.xml" ファイルでこの

<import resource="classpath:springBeanConfiguration.xml"/> 

または

<import resource="classpath*:springBeanConfiguration.xml"/> 

Answer 2

のようなものでなければなりません<context:component-scan base-package="com.codeEvaluator" />と<context:annotation-config>注釈を可能にする "@Autowired"
