项目名称：CarpoolDB,我在另一个应用程序名称Carpool中添加了该项目的jar.
运行拼车应用程序时,出现以下异常.
项目：拼车.
在这里,我因为“ carpoolService”作为“ Google Web应用程序”运行而没有自动连接而出现异常,但是在Tomcat下同样运行,并且正确注入了bean.
@Controller
public class PlacesSearchController {
@Autowired
CarpoolService carpoolService=null;
public CarpoolService getCarpoolService() {
return carpoolService;
}
public void setCarpoolService(CarpoolService carpoolService) {
this.carpoolService = carpoolService;
}
}
拼车应用程序上下文1.xml
我也有applicationContext-security.xml,用于春季安全.
项目：CarpoolDB
所有类都在com.company.carpooldb.db包中
public interface CarpoolService {

为什么我越来越
1. java.lang.NoClassDefFoundError：java.io.FileOutputStream是一个受限类.
我没有写任何文件
> GAE不支持我所知的少数API,但是我的应用程序已在MysqL上运行,并且我想同时支持这两种.我的意思是基于我的属性文件中设置的属性,我想有时使用MysqL,有时想使用GAE数据存储.
我正在使用Spring 3.
在这种情况下我该怎么办？
最佳答案
如鲍里斯(Boris)所述,问题似乎出在您的会话工厂上. GAE不支持jdbc,看起来您的sessionFactory为MysqL配置了：
原文链接：https://www.f2er.com/spring/531857.html<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect"><!--Which dialect is used of hibernate according to type of underlying database-->
org.hibernate.dialect.MysqLDialect
</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
如果您正在使用依赖于Hibernate的现有代码库,则可以尝试将Hibernate配置为由Cloud sql支持：https://developers.google.com/appengine/articles/using_hibernate
至于FileOutputStream问题,我相信log4j的默认附加器之一是FileAppender,因此仅不配置log4j就不能解决它-您需要明确配置它.查看该页面是否有帮助：http://blog.xam.de/2010/03/logging-in-google-appengine-for-java.html
