RestEASY, HIbernate, Maven 및 JBossAS5.1이 훌륭하게 재생되도록하기

Question

데이터 액세스를 위해 최대 절전 모드를 사용하는 안정적인 웹 서비스를 구축하려고합니다. Maven을 사용하여 빌드하고 JBossAS5.1에 배포해야합니다. 향후에는 EAP5.x가 될 것입니다.

RestEASY는 괜찮지 만 최대 절전 모드 종속성을 pom.xml에 추가하자마자 배포 후 즉시 WAR 충돌이 발생하여 최대 절전 모드 문제가 발생합니다.

저는 Java와 Maven을 사용하는 것이 상당히 편하지만 간단한 JSP 이상의 JavaEE는 처음입니다.

Answer 1

yup Maven에 포함 된 Hibernate JAR은 JBossAS의 JAR와 충돌합니다. 발견 된 종속 범위 : http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-core</artifactId> 
    <version>3.5.6-Final</version> 
    <scope>provided</scope> 
</dependency>  

해결되었습니다! :-)
