标题架构演变历史

spring开发环境搭建环境搭建

标题Maven构建的Spring项目需要哪些依赖？

Spring相关的依赖我参考的是这篇文章：

https://www.cnblogs.com/javafucker/p/7566733.html
1）spring核心依赖
spring-core、spring-beans、spring-context
2）spring dao依赖（提供JDBCTemplate）
spring-jdbc、spring-tx
3）spring web依赖
spring-web、spring-webmvc
4）spring test依赖
spring-test

web.xml解析

容器在解析web.xml时，首先会去读取`，提供应用程序上下文信息；

contextConfigLocation classpath:spring/root-context.xml

然后会加载节点，该节点会用到上下文的信息；

org.springframework.web.context.ContextLoaderListener

然后会加载拦截器节点，如果有多个拦截器，则是按照拦截器配置的顺序来进行调用的；

1、字符过滤器
web.xml中写法如下

<filter>
   <filter-name>CharacterEncodingFilter</filter-name>
   <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
   <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
   </init-param>
</filter>
<filter-mapping>
   <filter-name>CharacterEncodingFilter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

2、文件上传的过滤器
web.xml中写法如下

<filter>
   <filter-name>MultipartFilter</filter-name>
   <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
   <init-param>
      <param-name>multipartResolverBeanName</param-name>
      <param-value>multipartResolver</param-value>
   </init-param>
</filter>
<filter-mapping>
   <filter-name>MultipartFilter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

3、扩展form所支持的http方法的过滤器
web.xml中写法如下

<filter>
   <filter-name>hiddenHttpMethodFilter</filter-name>
   <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
   <filter-name>hiddenHttpMethodFilter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

浏览器form表单只支持GET与POST请求，而DELETE、PUT等method并不支持，spring3.0添加了一个过滤器，可以将这些请求转换为标准的http方法，使得支持GET、POST、PUT与DELETE请求，该过滤器为HiddenHttpMethodFilter。
需要注意的是，由于doFilterInternal方法只对method为post的表单进行过滤，所以在页面中必须如下设置：

<form action="..." method="post">
        <input type="hidden" name="_method" value="put" />
        ......
</form>

而不是使用：

    <form action="..." method="put">
            ......
    </form>

HiddenHttpMethodFilter的实现原理其实就是新建了个HttpMethodRequestWrapper类，覆写了getMethod()方法，也就是将原来本身的HTTP请求方式（POST）给隐藏掉了。

然后才会加载对应的节点；

DispatcherServlet是前端控制器设计模式的实现，提供SpringWebMVC的集中访问点，而且负责职责的分派，而且与
spring IOC容器无缝集成，从而可以获得Spring的优势。
关于DispatcherServlet的执行原理可以看这篇文章。
https://blog.csdn.net/jinnianshilongnian/article/details/84254470
其主要职责是调度工作，本身用于控制流程，具体为：

1.文件上传解析，如果请求类型是multipart将通过MultipartResolver进行文件上传解析；
2.通过HandlerMapping，将请求映射到处理器(返回一个HandlerExecutionChain，它包括一个处理器、多个HandlerInterceptor拦截器)；
3.通过handlerAdapter支持多种类型的处理器(handlerExceptionChain中的处理器)；
4.通过ViewResolver解析逻辑视图名到具体视图实现；
5.本地化解析；
6.渲染具体的视图等；
7.如果执行过程中遇到异常将交给handlerExceptionResolver来解析；

	<servlet>
       <servlet-name>spring</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:spring/applicationContext.xml</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
       <servlet-name>spring</servlet-name>
       <url-pattern>/</url-pattern>
    </servlet-mapping>

也就是说，web.xml中的加载顺序是：context-param -> listener -> filter > servlet；而同类型之间的加载顺序则是根据配置的顺序来进行加载的。所以我们配置的时候，需要注意下同类型标签的配置顺序；

完整的web.xml文件如下

一系列applicationContext配置文件

spring开发环境搭建环境搭建
因为spring的配置太多，我们这里分成好几个配置文件来进行配置，他们之间的关系是这样的。

  • applicationContext.xml
    • applicationContext-dao.xml
    • applicationContext-service.xml
    • applicationContext-web.xml

这里的配置文件被加载的流程是这样的。
1、applicationContext被web.xml中的下面代码加载
需要注意的是如果我们不像我这样显示的contextConfigLocation的值为classpath:spring/applicationContext.xml的话，系统是去查找默认值的

<servlet>
		<servlet-name>spring</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/applicationContext.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

2、applicationContext中代码如下

<?xml version="1.0" encoding="UTF-8"?>
<beans
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
	<!--使用通配符加载所有的properties配置文件-->
	<context:property-placeholder location="classpath:properties/*.properties"/>
	<!--加载所有的xml配置文件，大家可以发现我们为了统一xml配置文件都是applicationContext-xxx.xml这样的命名格式，就是为了能在这里用通配符一次匹配到所有的配置文件-->
	<import resource="applicationContext-*.xml"/>
</beans>

再次强调下<import resource="applicationContext-*.xml"/>加载所有的xml配置文件，大家可以发现我们为了统一xml配置文件都是applicationContext-xxx.xml这样的命名格式，就是为了能在这里用通配符一次匹配到所有的配置文件。

properties文件夹下面的配置文件和spring文件夹下的配置文件有什么差别

以properties下面的dao.properties文件为例：

dataSource.url=jdbc:mysql://127.0.0.1:3306/comment?useUnicode=true&characterEncoding=utf8
dataSource.username=root
dataSource.password=123456

很明显，dao.properties里面配置的是一些变量的值，applicationContext加载这些properties为后缀的配置文件是为了在applicationContext-dao.xml这些xml文件使用，比如applicationContext-dao.xml中有设置数据库相关信息的代码如下：

<property name="jdbcUrl" value="${dataSource.url}"/>
<property name="user" value="${dataSource.username}"/>
<property name="password" value="${dataSource.password}"/>

我们可以利用${dataSource.url}这样的语法引用被加载的dao.properties中的变量的值。
关于读取properties中的值我参考的这篇文章：
