答案 0 :(得分：0)
引起：java.lang.ClassNotFoundException：com.ibm.db2.jcc.DB2Driver
看起来您还没有在maven依赖项中添加 db2jcc 。请通过查看依赖关系树来验证：
mvn dependency:tree -Dverbose
如果您的测试在IDE中正常运行。您可以在类路径中手动添加 db2jcc - * jar。
如果您已在maven依赖项中指定了依赖项并仍然收到错误，那么您的应用程序可能会占用大量内存，并且maven无法将所有类加载到已分配的堆中。 它可以通过增加内存来进行可靠性测试来解决。
为此，请参阅here提到的答案。
