Answer 1

从您提供的堆栈跟踪。我看到：java.lang.IllegalStateException：无法加载 JDBC 驱动程序类 [com.ibm.db2.jcc.DB2Driver]

主要错误是因为 lib 中缺少 db2 驱动程序类的 db2jcc jar。请添加所需的驱动程序 jar 并重试。

Answer 2

我在 Tomcat 的 lib 文件夹中添加了 db2 jar，它工作正常，错误已解决。我之前在 pom 中添加了 jar 文件的依赖项，并认为 maven 会下载它们。

Answer 3

您似乎有一个名为 myDataSource 的数据源，它引用了一个 DB2 数据库。要访问数据库，您需要 DB2 的 JDBC 驱动程序。您可以在以下页面下载驱动程序。为了使用适当的驱动程序，您必须检查您拥有的 DB2 版本：

http://www-01.ibm.com/support/docview.wss?uid=swg21363866

下载后，解压缩并引用服务器中的驱动程序位置。

原因：org.springframework.beans.factory.BeanCreationException：在类路径资源 [applicationContext.xml] 中定义名称为“ myDataSource ”的 bean 创建错误：设置属性值时出错；嵌套异常是 org.springframework.beans.PropertyBatchUpdateException；嵌套的PropertyAccessExceptions(1) 是：PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' 抛出异常；嵌套异常是 java.lang.IllegalStateException: 无法加载 JDBC 驱动程序类 [ com.ibm.db2.jcc.DB2Driver ]
