标记不匹配错误是什么意思？

我投票关闭这个问题，因为这应该是给Spring Cloud团队的错误报告。@m.Deinum我投票不关闭这个问题。虽然我同意这是一个bug报告，但让我问以下问题：到目前为止，您读过多少“bug报告”解决方案？我认为这是一个向社区而不是开发团队询问现有问题的好地方。我建议您尝试可用的最新版本。我投票关闭此问题，因为这应该是向Spring Cloud团队提交的错误报告。@m.Deinum我投票不关闭此问题。虽然我同意这是一个bug报告，但让我问以下问题：到目前为止，您读过多少“bug报告”解决方案？我认为这是一个向社区而不是开发团队询问现有问题的好地方。我建议您尝试可用的最新版本。
