java - ClassNotFoundException : com. allen_sauer.gwt.log.client.WrappedClientThrowable

Question

在 tomcat 8.0.36 中启动我的应用程序时，我收到 com.allen_sauer.gwt.log.client.WrappedClientThrowable 类未找到异常。使用的库

- gwt-user-2.8
- gwt-servlet-2.7.0
- spring4gwt-0.0.1
- gwt-log-3.1.2

此类存在于 gwt-log 中，但位于包 com.allen_sauer.gwt.log.shared 中。我的应用程序代码引用了正确的包，但我仍然收到此异常:

不确定哪个库指的是旧包。任何帮助表示赞赏。提前致谢。

Answer 1

似乎您有不同版本的 gwt-user 和 gwt-servlet。

如果您可以发布完整的“mvn dependency:tree”(或 gradle 等效项)，那就太好了

EDIT:

感觉您正在使用有点过时的日志记录库。

尝试将这个人添加到您的依赖项中:compile 'com.allen-sauer.gwt.log:gwt-log:3.3.2
