Spring，Hibernate与谷歌应用程序引擎 [英] Spring, Hibernate with google app engine

问题描述

项目名称：CarpoolDB，我已经在另一个应用程序名称Carpool中为此项目添加了jar。
在运行Carpool应用程序时，出现以下异常。

项目：Carpool。
在这里，我收到了异常，因为carpoolService在作为Google Web应用程序运行时没有自动装入，但是同样在Tomcat下运行，并且bean正确地被注入。

  @Controller 
 public class PlacesSearchController {
 $ b $ @Autowired 
 CarpoolService carpoolService = null; 
 
公共CarpoolService getCarpoolService（）{
返回carpoolService; 
} 
 public void setCarpoolService（CarpoolService carpoolService）{
 this.carpoolService = carpoolService; 
} 
 
} 
  

carpool-application-context1.xml

另外我还有applicationContext-security.xml，用于弹簧安全。

项目：CarpoolDB
所有课程都在包中，com.company.carpooldb.db

  public interface CarpoolService {
 public boolean validateUser（User user）; 
 
 $ b @Service（carpoolService）
 public class CarpoolServiceImpl implements CarpoolService {
 $ b $ @Autowired 
 private CarpoolDao carpoolDao = null; 
 
 public CarpoolDao getCarpoolDao（）{
 return carpoolDao; 
} 
 
 public void setCarpoolDao（CarpoolDao carpoolDao）{
 this.carpoolDao = carpoolDao; 
 
 $ b @Override 
 public boolean validateUser（User user）{
 return carpoolDao.validateUser（user）;; 
} 
 
} 
 
 
 public interface CarpoolDao {
 public boolean validateUser（User user）; 
 
 $ b $ public class CarpoolDaoImpl extends HibernateDaoSupport implements CarpoolDao {
 @Override 
 public boolean validateUser（User user）{
 // TODO自动生成的方法存根
返回false;

为什么我得到
1. java.lang.NoClassDefFoundError：java.io.FileOutputStream是一个受限制的类。

我不写任何文件

1. GAE不支持少数API，我知道，但我的应用程序已经为MySQL工作，我想支持两者。我的意思是基于属性文件中设置的属性，我想在某些时候使用MySQL，有时想用GAE数据存储。
使用spring 3.




在这种情况下我应该做什么？


解决方案

<鲍里斯指出，这个问题似乎与你的会话工厂有关。 GAE不支持jdbc，它看起来像你的sessionFactory配置为mysql：

 < property name =hibernateProperties > 
<道具> 
< prop key =hibernate.dialect><！ - 根据底层数据库的类型使用hibernate的方言 - > 
 org.hibernate.dialect.MySQLDialect 
< / prop> 
< prop key =hibernate.show_sql> false< / prop> 
< /道具> 
< / property> 
  

如果您正在使用依赖于Hibernate的现有代码库，则可以尝试配置Hibernate来运行由Cloud SQL支持： https://developers.google.com/appengine/articles/using_hibernate





至于FileOutputStream问题，我相信log4j的一个默认appender是一个FileAppender，所以根本不配置log4j就不会修复它 - 你需要以明确配置它。查看此页是否有帮助： http：// blog .xam.de / 2010/03 / logging-in-google-appengine-for-java.html




Project Name: CarpoolDB, I have added the jar for this project in another application name Carpool. While running the Carpool app I am getting following exception.

Project: Carpool. Here i am getting exception as "carpoolService" not getting autowired while running as "Google Web application" but same runs under Tomcat and beans properly get injected.

@Controller
public class PlacesSearchController {

    @Autowired
    CarpoolService carpoolService=null;

    public CarpoolService getCarpoolService() {
        return carpoolService;

    public void setCarpoolService(CarpoolService carpoolService) {
        this.carpoolService = carpoolService;
    }

} 

carpool-application-context1.xml

Also I have applicationContext-security.xml, for spring security.

        @Override
        public boolean validateUser(User user) {

The server is running at http://localhost:8888/

Why I am getting as 1. java.lang.NoClassDefFoundError: java.io.FileOutputStream is a restricted class.

I am not writing anything on file

1. GAE doesn't support few API that I am aware of but my application already working for MySQL and I want to support both. I mean based on property set in my property file I want to use sometime MySQL and sometime want to work with GAE datastore.

I am using spring 3.

What I should do in this case?

解决方案

As Boris notes, the issue appears to be with your session factory. GAE doesn't support jdbc, and it looks like your sessionFactory is configured for mysql:

<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>

If you're working with an existing codebase that depends on Hibernate, you could try configuring Hibernate to run backed by Cloud SQL: https://developers.google.com/appengine/articles/using_hibernate

As for the FileOutputStream issue, I believe one of the default appenders for log4j is a FileAppender, so simply not configuring log4j won't fix it - you'll need to explicitly configure it. See if this page helps: http://blog.xam.de/2010/03/logging-in-google-appengine-for-java.html
