org.springframework.ui.Model 是 Spring MVC 框架中的一个接口，用于在控制器（Controller）和视图（View）之间传递数据。它提供了一种方便的方式来将数据添加到模型中，以便在视图层（如 JSP、Thymeleaf 等）中使用这些数据进行渲染。的属性添加到模型中，并将其值设置为 “Hello, World!的视图，该视图可以使用模型中的数据进行渲染。方法从模型中移除某个属性。方法清空模型中的所有属性。方法向模型中添加属性。方法从模型中获取属性。

这个是在整合freemarker的时候出现的问题,在添加依赖spring-context-support.jar之后就好了
但是我在搭建框架的时候出现的问题是明明添加了这个依赖,但是出现一个问题

解决方案：添加spring-webmvc好多人都不知道org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer这个类到底在哪个jar里面所以找了半天都没找到，这里我说明下确切位置：
spring-framework-2.5.6\dist\modules\spring-webmvc.jar...

问题详情：java.lang.ClassNotFoundException: freemarker.template.TemplateHashModelEx
今天为了使用freemarker模板，想整合到springMVC中，但是这个异常困扰了我好长时间。还是有必要写一篇文章来记录一下这个辛酸的过程了。
其实出现找不到类的异常，一般情况下都是找不到jar包。很自然的会去查看freemarker

刚刚介绍了Thymeleaf模板，接下来我们学习FreeMarker模板，无论是语法还是配置等，两者都有很多相似的地方。在src/resources/templates下新建index.ftl（注意文件后缀），使用${msg}接收后来传送的数据，文件内容如代码。接下来配置FreeMarker模板属性，与Thymeleaf模板配置类似，唯一需要注意的是模板文件后缀配置的是FTL文件。接下来，创建一个IndexController进行测试，内容如代码。新建项目，在项目中加入Freemarker依赖，如代码。

今天发现org.springframework.ui.Model addAttribute 方法放进去的数字超过三位数时被格式化，前端获取到的格式是这样的9,999。尝试使用parseInt转成数字，结果被转成9。
