为什么我会收到此错误 "org.springframework.webflow.engine.NoMatchingTransitionException"
Why I am getting this error "org.springframework.webflow.engine.NoMatchingTransitionException"
我的代码在我的本地设置上 运行 非常好，只是尝试添加更新的代码并重新启动服务器，我得到了这个错误，然后我恢复了这些更改，但错误仍然存在，清理了我的项目 100 次。
我正在使用 spring web-flow..
请参考 error.I 的屏幕截图，我也在文本框中粘贴了错误...
我也贴上action-state module-home的代码片段，这里指出了错误。
提前致谢..请帮忙!!!!!!!!!!

Evgeny 在评论中说的是正确的。您的方法 eventHandler.getEventId(flowRequestContext) 正在返回字符串值 "event-error/HTTP_NOT_FOUND"，并且您没有为此定义转换。
因此您要么需要确定该代码返回意外值的原因（可能是抛出的异常？），要么为其添加转换。
