信息:在类路径上未检测到 Spring WebApplicationInitializer 类型 [英] INFO: No Spring WebApplicationInitializer types detected on classpath
问题描述
我有一个 spring 项目，当我从 Eclipse 部署时，它在我的 tomcat7 服务器上运行良好:运行方式 >> 在服务器上运行.在 Eclipse 选项卡服务器"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，我还看到了文件夹: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，我确认在我的 tomcat7 服务器上一切正常！
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
WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:my_project' did not find a matching property.

现在:问题这是当我在同一个 tomcat7 服务器/var/lib/tomcat7/webapps 中部署同一个应用程序(使用文件 .war)时
Now: The problem It is when I deploy the same app (using a file .war) in the same tomcat7 server /var/lib/tomcat7/webapps
我可以在没有数据的情况下打开我的初始网页，
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
我发现错误:我有一个使用 jdk 1.6 构建的库.Spring 主控制器和组件都在这个库中.以及我如何使用 jdk 1.7，它没有找到 1.6 中内置的类.
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性级别: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:首选项Java编译器.
I setup this option in Eclipse: PreferencesJavaCompiler.
