Question

具有使用Java 11编译的EAR应用程序。部署到Wildfly 14时，返回以下错误：

Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ef' defined in class path resource [application-context.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [application-context.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [oracle.jdbc.driver.OracleDriver]

...

Caused by: org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [oracle.jdbc.driver.OracleDriver]
    at deployment.test-1.0.ear//org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:121)

与Java 8编译的同一应用程序部署没有问题（实际上，它是作为Java 8应用程序启动的）。因此，驱动程序本身似乎不是问题。

这是Wildfly路径modules / system / layers / base / com / oracle / main中的 module.xml ：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.5" name="com.oracle">
  <resources>
    <resource-root path="ojdbc6.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>
  </dependencies>
</module>

更改EAR应用程序的最佳方法是什么，以便在使用Java 11进行编译时可以正确地伪装？

Answer 1

ojdbc6驱动程序不支持Java11。根据What are the Oracle JDBC releases versus JDK versions，只有具有数据库18.3的ojdbc8驱动程序完全支持Java 11。

要么升级驱动程序（可能还有数据库），要么继续使用Java 8。

EAR使用Java 11部署错误编译
