信息：没有在类路径上检测到Spring WebApplicationInitializer类型 [英] INFO: No Spring WebApplicationInitializer types detected on classpath

问题描述

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 >>在服务器上运行。
在eclipse选项卡Servers中我看到：

I have a spring project that runs fine on my tomcat7 server when I deploy from eclipse: Run As >> Run on server. In the eclipse tab "Servers" I see:

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

我看到项目在：

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

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

And, I also see the folders: conf,logs,temp,webapps,work,wtpwebapps

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

I confirm that all runs fine on my tomcat7 server when I deploy from eclipse!

在eclipse控制台中我得到：

In eclipse console I get:

Apr 08, 2014 3:26:59 PM org.apache.tomcat.util.digester.SetPropertiesRule begin

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

Now: The problem It is when I deploy the same app (using a file .war) in the same tomcat7 server /var/lib/tomcat7/webapps

我可以打开我的初始页面网页但没有数据，

I can open the my initial page web BUT without data,

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：

When I restart tomcat7 I get in the log file:

INFO: Destroying ProtocolHandler ["http-bio-8843"]

推荐答案

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。

I found the error: I have a library that it was built using jdk 1.6. The Spring main controller and components are in this library. And how I use jdk 1.7, It does not find the classes built in 1.6.

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。

The solution was built all using "compiler compliance level: 1.7" and "Generated .class files compatibility: 1.6", "Source compatibility: 1.6".

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

I setup this option in Eclipse: Preferences\Java\Compiler.
