Spring MVC : 다중 모듈 프로젝트 - 하나의 모듈에서 다른 모듈로 bean 정의를 가져올 수 없다.

Question

나는 웹 모듈과 영속 모듈이라는 두 개의 maven 모듈로 구성된 maven 프로젝트를 가지고있다. 웹 모듈에서 스프링 MVC가 사용됩니다. 의 web.xml :

<web-app id="WebApp_ID" version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> 

    <display-name>Web1</display-name> 

    <servlet> 
     <servlet-name>mvc-dispatcher</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>mvc-dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 

    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value> 
    </context-param> 

    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 

</web-app> 

그리고 이것은 지속성 모듈의 샘플 스프링 빈 설정 파일 (내가 시간을 절약하기 위해 그것을 단순화를)입니다 :

 <?xml version="1.0" encoding="UTF-8"?> 
     <beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans 
      http://www.springframework.org/schema/beans/spring-beans.xsd"> 
     <bean name="user" class="com.roganin.auto.persistence.User"> 
     <property name="userName" value="Jack"/> 
     </bean> 

     </beans> 

문제 : 나는 수입을하려고 할 때 mvc-dispatcher-servlet.xml에서 다음을 사용하십시오.

이 가져 오기를 해결할 수 없습니다.

그러나, 홈페이지 방법 간단한 2 모듈 프로젝트가 완벽하게 작동합니다 :

와 나는 다음과 같은 예외를받을 수 있습니다.

이제는 지속성 모듈의 빈을 웹 모듈에 삽입 할 수 없기 때문에 붙어 있습니다.

많이 검색되었습니다. 도와주세요.

업데이트 : 웹 모듈에 대한 나의 POM :

는 "자동 웹을"어디는 - 웹 모듈이며, 및 "자동 지속성"지속성 모듈입니다.

Answer 1

클래스를 찾을 수 없습니다. 종속성을 지정해야합니다. 웹 모듈은 지속성 모듈에 따라 다르므로 클래스 패스에 포함됩니다.

Answer 2

구성 파일을 올바르게로드하지 않았기 때문입니까? Dispatcher 서블릿 구성의 contextConfigLocation을 web.xml

<servlet-name>mvc-dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <init-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value/> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet>
