SpringMVC详解（二）

通过上篇博客，我们能编写一个 SpringMVC 的入门实例，但是为什么要这样写？这样写有啥好处？通过这篇博客我们会有详细的了解。

#### 1、SpringMVC 详细介绍 ####

通过入门实例，我们大概知道 SpringMVC 的作用，那么它到底是什么呢？

Spring Web MVC是一种基于Java的实现了Web MVC设计模式的请求驱动类型的轻量级Web框架，即使用了MVC架构模式的思想，将web层进行职责解耦，基于请求驱动指的就是使用请求-响应模型，框架的目的就是帮助我们简化开发，Spring Web MVC也是要简化我们日常Web开发的。

与之相反的是基于组件的、事件驱动的Web框架，如Tapestry、JSF等，在此就不介绍了。

Spring Web MVC也是服务到工作者模式的实现，但进行可优化。前端控制器是DispatcherServlet；应用控制器其实拆为处理器映射器(Handler Mapping)进行处理器管理和视图解析器(View Resolver)进行视图管理；页面控制器/动作/处理器为Controller接口（仅包含ModelAndView handleRequest(request, response) 方法）的实现（也可以是任何的POJO类）；支持本地化（Locale）解析、主题（Theme）解析及文件上传等；提供了非常灵活的数据验证、格式化和数据绑定机制；提供了强大的约定大于配置（惯例优先原则）的契约式编程支持。

#### 2、SpringMVC 处理请求流程 ####

![1120165-20170816195217834-1322829917.png][]

第一步：用户发送请求到前端控制器（DispatcherServlet）。

第二步：前端控制器请求 HandlerMapping 查找 Handler，可以根据 xml 配置、注解进行查找。

第三步： 处理器映射器 HandlerMapping 向前端控制器返回 Handler

第四步：前端控制器调用处理器适配器去执行 Handler

第五步：处理器适配器执行 Handler

第六步：Handler 执行完成后给适配器返回 ModelAndView

第七步：处理器适配器向前端控制器返回 ModelAndView

ModelAndView 是SpringMVC 框架的一个底层对象，包括 Model 和 View

第八步：前端控制器请求试图解析器去进行视图解析

根据逻辑视图名来解析真正的视图。

第九步：试图解析器向前端控制器返回 view

第十步：前端控制器进行视图渲染

就是将模型数据（在 ModelAndView 对象中）填充到 request 域

第十一步：前端控制器向用户响应结果

下面我们对上面出现的一些组件进行解释：

可以总结出：需要我们开发的工作只有处理器 Handler 的编写以及视图比如JSP页面的编写。可能你还对诸如前端控制器、处理器映射器等等名词不太理解，那么接下来我们对其进行详细的介绍。

#### 3、配置前端控制器 ####

在 web.xml 文件中进行如下配置：

#### 4、配置处理器适配器 ####

在 springmvc.xml 文件中配置。用来约束我们所需要编码的 Handler类。

第一种配置：编写 Handler 时必须要实现 Controller

#### 5、编写 Handler ####

在 springmvc.xml 文件中配置。通俗来讲，就是请求的 URL 到我们这里所编写的 Handler 类的某个方法进行一些业务逻辑处理。

我们在上面讲解了两个处理器适配器来约束 Handler，那么我们就通过上面两种配置分别编写两个 Handler

第一种：实现Controller 接口

总结：通常我们使用第一种方式来编写 Handler ，但是第二种没有返回值，我们可以通过 response 修改相应内容，比如返回 json 数据。

所以具体使用哪一种根据实际情况来判断。

#### 5、配置处理器映射器 ####

在 springmvc.xml 文件中配置。通俗来讲就是请求的 URL 怎么能被 SpringMVC 识别，从而去执行我们上一步所编写好的 Handler

第一种方法：

这样配置的话，那么请求的 URL，必须为 http://localhost:8080/项目名/hello.do

第二种方法：

这种配置请求的 URL可以为 http://localhost:8080/项目名/hello1.do，或者http://localhost:8080/项目名/hello2.do

总结：上面两种处理器映射器配置可以并存，前端控制器会正确的去判断 url 用哪个 Handler 去处理。

#### 6、配置视图解析器 ####

第一种配置:

如果这样配，那么在 Handler 中返回的必须是路径+jsp页面名称+".jsp"

第二种配置：

如果这样配，那么在 Handler 中只需要返回在 view 文件夹下的jsp 页面名就可以了。

#### 7、DispatcherServlet.properties ####

上面我们讲解了各种配置，可能有人会问这么多配置，万一少配置了一样，那不就不能运行了，那我们能不能不配置呢？答案是肯定的，SpringMVC 给我们提供了一个 DispatcherServlet.properties 文件。系统会首先加载这里面的配置，如果我们没有配置，那么就默认使用这个文件的配置；如果我们配置了，那么就优先使用我们手动配置的。

在 SpringMVC 运行之前，会首先加载 DispatcherServlet.properties 文件里面的内容，那么我们来看看这里面都是什么。

我们可以从上面得出，如果我们不手动进行各种配置，那么也有会默认的

①、处理器适配器默认：org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter

②、处理器映射器默认：org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping

③、视图解析器默认：org.springframework.web.servlet.view.InternalResourceViewResolver
