Dynamic Web Project 的例子

准备用Spring、SpringMVC、Hibernate架构做一个登录的例子，同时也是我第一次尝试用实体类生成表

1.配置好server后，新建一个Dynamic  Web Project ，取名demo

2.导入Spring ，hibernate等框架要用到的jar包

3,配置：

没有找到可以注入的UserDao 类型的bean,心想bean没有纳入Spring的管理，于是改变配置文件的位置

org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.gacinfo.service.UserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@javax.annotation.Resource(shareable=true, mappedName=, description=, name=, type=class java.lang.Object, authenticationType=CONTAINER)}

改变位置后发现database.properties中的键值对不能够供Spring的配置文件使用,应该先搞清楚一个问题，那就是auction中，是如何让Spring的配置文件读到了database.properties。

org.springframework.beans.factory.BeanDefinitionStoreException: 

Invalid bean definition with name 'dataSource' defined in file [E:\java\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\demo\WEB-INF\classes\applicationContext-hibernate.xml]: Could not resolve placeholder 'database.driverClassName'

仍然出错，先看看是不是路径和拼写错误，再看看是不是配置了多个placeHolder

结果发现改错文件了，改成了auction中的applicationContext.xml

14：08出错

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [E:\java\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\demo\WEB-INF\classes\applicationContext-hibernate.xml]: Invocation of init method failed; nested exception is java.io.FileNotFoundException: class path resource [hibernate/hibernate.cfg.xml] cannot be resolved to URL because it does not exist

在建表时出错：

No identifier specified for entity: com.gacinfo.domain.User

解决之道：给该实体类对应的表指定主键

当务之急：如何指定主键？ @Id 即可

为什么现在连表也没有生成？

怎么解决路径的问题?

The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jre6\bin;.;C:\Windows\Sun\Java\bin;C:\Windows\system32;C:\Windows;C:/Program Files/Java/jdk1.6.0_19/bin/../jre/bin/client;C:/Program Files/Java/jdk1.6.0_19/bin/../jre/bin;C:/Program Files/Java/jdk1.6.0_19/bin/../jre/lib/i386;.;C:\Program Files\Java\jdk1.6.0_19\bin;C:\Program Files\Java\jdk1.6.0_19\jre\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\Windows7Master;C:\Program Files\MySQL\MySQL Server 5.1\bin;C:\Program Files\TortoiseSVN\bin

按照网上的解决方案，下了一个tcnative-1.dll文件，放在了C:\Windows\system32，结果

An incompatible version 1.1.2 of the APR based Apache Tomcat Native library is installed, while Tomcat requires version 1.1.17，唉，这个问题先放这里吧，据网上说，只要下载一个高版本，问题就能得以解决

[SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:demo' did not find a matching property.

通过网上的设置解决 （控制台中的server才有general属性，Project Explorer指的就是左边的窗口）

java.lang.IllegalArgumentException: Document base E:\java\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\demo does not exist or is not a readable directory
