我想在Tomcat容器中部署三个Grails Web应用程序。我正在使用Grails 1.3.7和Tomcat 7.0.23。我想将所有公用的jar放在tomcat / shared / lib目录中。为什么？我想使用较小的war文件并减少PermGen中所需的内存量。
我在 conf / catalina.properites中 配置下一行 __
shared.loader=${catalina.base}/shared/lib,${catalina.base}/shared/lib/*.jar
对于所有三个应用程序，我执行
grails war
我将WEB-INF / lib下的所有* .jars复制到$ CATALINA_HOME / shared / lib中
后来我为每个应用程序生成没有jar的war文件
grails war --nojars
我把这三场大战都放在了 tomcat / webapps 目录中。 conf / DataSource.groovy中 的生产数据 源 对于每个应用程序如下所示。
应用程式A）
production { dataSource { dbCreate = "update" username = "userA" password="password" url = "jdbc:mysql://localhost:3306/applicationA" driverClassName = "org.gjt.mm.mysql.Driver" } }
App B）
production { dataSource { dbCreate = "update" username = "userB" password="password" url = "jdbc:mysql://localhost:3306/applicationB" driverClassName = "org.gjt.mm.mysql.Driver" } }
App C）
production { dataSource { dbCreate = "update" username = "userC" password="password" url = "jdbc:mysql://localhost:3306/applicationC" driverClassName = "org.gjt.mm.mysql.Driver" } }
当我启动Tomcat时，日志如下所示：

我该怎么解决？
在grais war命令中生成的某些jar无法在每个应用程序之间共享。
无法共享的 jar，应该位于webapps / appA / WEB-INF / lib中
grails-bootstrap-1.3.7.jar grails-gorm-1.3.7.jar grails-web-1.3.7.jar grails-core-1.3.7.jar grails-resources-1.3.7.jar spring-security-core-3.0.5.RELEASE.jar grails-crud-1.3.7.jar grails-spring-1.3.7.jar
可以共享的jar，可以 位于tomcat / shared / lib中

不幸的是，这在Grails中不起作用，并且存在比数据源更多的问题。我们考虑将其修复为2.0，但是仍然存在问题，因此，直到2.0.x发行版，它才起作用。
问题是核心Grails jars中的静态变量。由于这些jar中的类是由共享的类加载器加载的，因此静态信息在Tomcat中是共享的。只要jar在每个war文件中，它们都由战争专用的类加载器加载，并且静态变量之间没有冲突。因此，在解决此问题之前，您需要部署完整的war，或者至少将grails-*。jar文件保留在war中。
