郎啊郎别太忙/alang: GAE(Google App Engine) 对 struts Spring 等的支持情况

完整描述见这里：(要fuckgfw)

Spring MVC

Version: 2.5.6

Status: COMPATIBLE

To see Spring's MVC framework running on App Engine, check out the autoshoppe sample application.

If you're using Spring forms (e.g. using the spring-form.tld tag library and subclassing SimpleFormController), you will need to register custom editors for your properties. This is covered in http://groups.google.com/group/google-appengine-java/browse_thread/thread/d93fd7385bf85bf7.

Spring ORM

Version: 2.5.6

Status: COMPATIBLE

To get Spring working with the App Engine-provided JPA interface, follow the instructions at http://objectuser.wordpress.com/2009/05/19/spring-jpa-in-google-app-engine/, which discusses a workaround to the dependency on javax.naming needed for @PersistenceContext. A more complex workaround is available at http://groups.google.com/group/google-appengine-java/browse_thread/thread/187d41712ec1d394.

Spring Security

Version(s): ?

Status: SEMI-COMPATIBLE

To work around a ClassNotFoundException, you can use a re-compiled version of the library which adds a StringInsensitiveComparator class -- the download is provided at http://www.google-app-engine.com/blog/post/Spring-security-fix-for-google-app-engine.aspx.

See http://www.dotnetguru2.org/bmarchesson/index.php?p=1100 for tips on how to get Spring Security running with App Engine and GWT (in French).

Stripes Framework

Version(s): ?

Status: COMPATIBLE

The default multipartwrapper implementation needs a temporary directory on the local file system for file uploads, which App Engine doesn't allow. The workaround is to create your own implementation -- more details at http://groups.google.com/group/google-appengine-java/browse_thread/thread/81dbcf7cf2281014.

Struts 1

Version: 1.2.28

Status: COMPATIBLE

Struts 2

Version(s): ?

Status: COMPATIBLE (see notes)

Struts will not initially work because the OGNL permissions which the framework relies on can't be set due to security restrictions in App Engine's sandbox. However, some users have documented a workaround at http://groups.google.com/group/google-appengine-java/browse_thread/thread/19018b0317f27817.

Will need to set devMode to false in struts.xml: <constant name="struts.devMode" value="false" />

这个人的博客上也描述了如何使用 Struts 2 with App Engine：
