部署在Tomcat 8.0.3上

Question

我試圖在Tomcat 8.0.3上部署我的Spring應用程序。 servlet容器使用jdk 1.0.7_51。我能夠通過

做部署MVN tomcat7：插件

但是當Tomcat的嘗試運行應用程序。在日誌文件中我得到這個異常：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in URL [file:/home/myApp/apache-tomcat-8.0.3/webapps/myApp/WEB-INF/classes/database.xml]: Invocation of init method failed; nested exception is java.lang.SecurityException: class "org.eclipse.persistence.sessions.coordination.CommandProcessor"'s signer information does not match signer information of other classes in the same package

我也運行

，我得到這樣的結果

我該如何解決它？

Answer 1

您有多個JAR提供來自包org.eclipse.persistence.sessions.coordination的類，但其中一些JAR已簽名且一些未簽名。 Java類加載器不允許這樣做。

這個問題很容易解決，取決於具體情況。

如果由簽名的JAR提供的類也由無符號的JAR提供，並且應用程序CAN可以在沒有簽名的JAR的情況下運行，那麼只需刪除簽名的JAR。

如果由無符號JAR提供的類也由帶簽名的JAR提供，並且應用程序CAN可以在沒有未經簽名的JAR的情況下運行，那麼只需刪除未簽名的JAR。

如果由簽名JAR提供的類也由無符號JAR提供，但是應用程序無法在沒有簽名JAR的情況下運行，那麼您需要強制Tomcat加載無符號JAR（s）第一。以下是ASF如何與Jira一起解決在Tomcat 8上運行的Jira 6.2的這個問題。這需要添加到Web應用程序的context.xml中。

<Resources> 
    <!-- Trick to force this JAR to be searched for classes before all others 
     to work around a Jira bug --> 
    <PreResources className="org.apache.catalina.webresources.FileResourceSet" 
       base="${catalina.base}/webapps/jira/WEB-INF/lib/jira-api-6.2.jar" 
       webAppMount="/WEB-INF/lib/jira-api-6.2.jar" /> 
</Resources> 

與刪除一樣，您可以翻轉它以導致簽名的JAR首先被加載。

如果以上任何一項工作都無法解決，那麼您可以解壓簽名的JAR並將其重新打包，而無需簽名，但是如果預計任何地方都有簽名的JAR，則可能會破壞某些內容。

我解決了改變了我的POM從：

<dependencies> 

    <dependency> 
     <groupId>org.eclipse.persistence</groupId> 
     <artifactId>org.eclipse.persistence.jpa</artifactId> 
     <version>2.5.1</version> 
    </dependency> 

    <dependency> 
     <groupId>org.eclipse.persistence</groupId> 
     <artifactId>eclipselink</artifactId> 
     <version>2.3.2</version> 
    </dependency> 

</dependencies> 

到：

<dependencies> 

    <dependency> 
     <groupId>org.eclipse.persistence</groupId> 
     <artifactId>org.eclipse.persistence.jpa</artifactId> 
     <version>2.5.1</version> 
    </dependency> 


    <dependency> 
     <groupId>org.eclipse.persistence</groupId> 
     <artifactId>eclipselink</artifactId> 
     <version>2.5.1</version> 
    </dependency> 

</dependencies> 

我修改只的EclipseLink版本
