이것은 첫 번째 Spring 애플리케이션입니다. 도메인에는 제품 및 제품 유형이라는 두 가지 클래스가 있습니다.Spring 4 + Hibernate 4 + JSF 2.2 + PrimeFaces 4 - 객체 속성에 액세스 할 때 NullPointerException이 발생했습니다.
나는 @Controller 주석을 통해 관리 빈을 액세스하는거야, 그리고 범위는 @Scope("request")
applicationContext.xml이다

내 faces-config.xml에는 다음 항목 만 있습니다. 의 ContextLoaderListener와 RequestContextListener :
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
그리고
은 web.xml 파일에 난 두 개의 리스너를 추가했다. DispatcherServlet을 더합니다.ProductRepository는 @Repository으로 주석을 달고 @PersistenceContext을 사용합니다.
ProductMB는 ProductRepository를 @Autowired으로 삽입합니다.
