springMVC+Hibernate 使用配置 -

博客分类：
本文描述下 sypro 项目中使用 springMVC+Hibernate配置，初学SpringMVC做下简单整理解。
1.web项目首先我们要使用 web.xml文件将 spring配置引入进来
&?xml version="1.0" encoding="UTF-8"?&
&web-app version="2.5" xmlns="/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

部署applicationContext的xml文件，如果在web.xml中不写任何参数配置信息，默认的路径是”/WEB-INF/applicationContext.xml，在WEB-INF目录下创建的xml文件的名称必须是applicationContext.xml。如果是要自定义文件名可以在web.xml里加入contextConfigLocation如下，在&param-value& &/param-value&里指定相应的xml文件名，如果有多个xml文件，可以写在一起并一“,”号分隔

加载contextConfigLocation则交给监听来实现

2.applicationContext.xml 文件常用配置，在该项目中使用的自定义写法 将 applicationContext.xml 重命名为： spring-mvc.xml ,注意如果不使用自定义写法applicationContext.xml则存放在 /WEB-INF/applicationContext.xml目录且不可重命名
applicationContext.xml （spring-mvc.xml） 常用配置如下：
&?xml version="1.0" encoding="UTF-8"?&

只有前台页面，参考意义不大
缺少addProperty和create方法
请问一下，这些漏洞用appscan扫描出来以后怎么查看具体漏洞 ...hiberante悲观锁和乐观锁怎么用整合到spring(想用注解的方式)里
悲观锁网上找了半天，全是单个的，没有整合进spring里,难道要先用getHibernateTelmple().getSession(....)先配好了来？
有注解配悲观锁吗？
乐观锁加个@Version好像就ok了，测了下，只要更新数据就会自动加1java - Spring 3.2 + Hibernate 4 OpenSessionInViewFilter - Stack Overflow

J it only takes a minute:
I'm a Spring newbie trying my first app.
My hibernate gets closed before the view is rendered and having problems with lazy loaded properties (expected behavior).
I've added the OpenSessionInViewFilter to my web.xml and caused the following:
java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?
Beforehand It was working fine with the default servlet context config I've had (can someone tell me why?).
So I've added the following:
&context-param&
&param-name&contextConfigLocation&/param-name&
&param-value&
/WEB-INF/springapp-servlet.xml
&/param-value&
&/context-param&
&listener&
&listener-class&org.springframework.web.context.ContextLoaderListener&/listener-class&
&/listener&
The new error went away..but still getting a no session exception from hibernate
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.test.model.Store.categories, could not initialize proxy - no Session
I've put a debug message in one of my controllers and it seems that its being initialized 3 times.
Maybe I have more than one instance of hibernate session factory bean?
My controller methods are marked @Transactional and everything worked until I've attempted to leave the session open to make the lazy fields available for the view.
My full web.xml (with the new context addition, worked fine without it before I've added the hibernate filter):

My controllers where initialized twice, the same config was used by the root ApplicationContext and by the FrameworkServlet.
I've had two contexts initialized.
I've created a config for the root context named springapp.xml and moved all my middle tier configuration there and left my web tier configuration in springapp-servlet.xml
My web.xml now looks like this and everything works fine:
&context-param&
&param-name&contextConfigLocation&/param-name&
&param-value&
/WEB-INF/springapp.xml
&/param-value&
&/context-param&

&/servlet&
&servlet-mapping&
&servlet-name&springapp&/servlet-name&
&url-pattern&/&/url-pattern&
&/servlet-mapping&
To solve the problem in my case it was just missing this line
in the application-context file.
The @Transactional annotation over a method was not taken into account.
Hope it will help someone

hibernate乐观锁和悲观锁学习
上传大小：36KB
1 ． 首先为 TUser 的 class 描述符添加 optimistic-lock 属性：
&hibernate-mapping&
&class name=&org.hibernate.sample.TUser& table=&t_user& dynamic-update=&true&
dynamic-insert=&true& optimistic-lock=&version&&
&/hibernate-mapping&
optimistic-lock 属性有如下可选取值：
none：无乐观锁
version：通过版本机制实现乐观锁
dirty：通过检查发生变动过的属性实现乐观锁
all：通过检查所有属性实现乐观锁
其中通过 version 实现的乐观锁机制是 Hibernate 官方推荐的乐观锁实现，同时也是 Hibernate 中，目前唯一在数据对象脱离 Session 发生修改的情况下依然有效的锁机制。因此，一般情况下，我们都选择 version 方式作为 Hibernate 乐观锁实现机制。
