信息:没有在类路径上检测到Spring WebApplicationInitializer类型

Question

当我从eclipse部署时,我有一个在我的tomcat7服务器上正常运行的spring项目:Run As >> Run on server.在eclipse选项卡"Servers"中,我看到:

Servers
 Tomcat v7.0 Server at localhost [Started, Synchronized]
   my_project [Synchronized]
     spring-web-3.2.4-RELEASE.jar

我的项目:

• 不使用web.xml,我使用javaconf @ annotations.
• 不使用maven,我使用用户库

我看到该项目在:

/srv/applications/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0

而且,我还看到了文件夹:conf,logs,temp,webapps,work,wtpwebapps

我确认当我从eclipse部署时,我的tomcat7服务器上的所有运行正常!

在eclipse控制台中,我得到:

现在:问题当我在相同的tomcat7服务器/ var/lib/tomcat7/webapps中部署相同的应用程序(使用文件.war)时

我可以打开我的初始页面网络但没有数据,

我在日志中看到:

INFO: No Spring WebApplicationInitializer types detected on classpath

当我重新启动tomcat7时,我进入了日志文件:

Answer 1

我发现了错误:我有一个使用jdk 1.6构建的库.Spring主控制器和组件位于此库中.我如何使用jdk 1.7,它没有找到1.6中构建的类.

该解决方案全部使用"编译器合规级别:1.7"和"生成的.class文件兼容性:1.6","源兼容性:1.6"构建.

我在Eclipse中设置了这个选项:Preferences\Java\Compiler.

谢谢大家.

Answer 2

我愚蠢的原因是：自动构建被禁用！

Answer 3

这是常见错误，请确保您的 file.war 已正确构建。只需打开 .war 文件并检查您的 WebApplicationInitializer 是否在那里。
