spring mvc官网下最新jar搭建框架-静态资源访问处理-注解-自动扫描

1.从官网下载spring相关jar http://spring.io/projects 点击SPRING FRAMEWORK

2.从GitHtb下载

3.向下滚动找到Downloading Artifacts 点击

4.点击Artifacts--》libs-release-local--》org--》springframewor--》spring

5.选中一个自己需要的版本（我选了4.2.5）

6.下载后的文件

配置文件的规范约束下面文件夹有的都可以写(我用到了beans, context, mvc三个, 如果需要配置数据源的可以加jdbc)

7.创建项目并配置环境

下面是贴代码：

applicationContext.xml (默认在WEB-INFO/applicationContext.xml)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-4.2.xsd">
    <!-- 目前只是使用spring的web-mvc功能 数据源切面整合持久化框架可在此配置 -->
</beans>

spring-webmvc-dispatcher-servlet.xml      (默认为DispacherServlet-servlet.xml)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"        ##配置视图解析类
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context" ##自动扫描
    xmlns:mvc="http://www.springframework.org/schema/mvc"　　　　　##静态资源处理
    xsi:schemaLocation="
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.2.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">
    
    <!-- 自动扫描的包名 -->
    <context:component-scan base-package="cn.zjx.controller"/>
    <bean id="annotationUrlHandlerMapping" 
          class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
    
    <!-- 视图解释类 --> 
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix" value="/WEB-INF/views/" />
          <property name="suffix" value=".jsp" />
    </bean>
    
    <!-- 默认的注解映射的支持 
        加<mvc:resources...前，要加上<mvc:annotation-driver/>，否则servlet控件器会解析失败
    -->  
    <mvc:annotation-driven />
   
    <!-- 对静态资源文件的访问  方案一 （二选一） -->  
    <!-- <mvc:default-servlet-handler/> -->
    
    <!-- 对静态资源文件的访问  方案二 （二选一）cache-period 缓存周期-->
    <mvc:resources mapping="/resource/js/**" location="/resource/js/" cache-period="31556926"/>
    <mvc:resources mapping="/resource/css/**" location="/resource/css/" cache-period="31556926"/>
    <mvc:resources mapping="/resource/images/**" location="/resource/images/" cache-period="31556926"/>
</beans>

对静态资源文件的访问的其它方式:
  交由上级web容器处理,在web.xml中的org.springframework.web.servlet.DispatcherServlet 配置之前加入如下代码：

　　<servlet-mapping>   
    <servlet-name>default</servlet-name>   
    <url-pattern>*.css</url-pattern>   
　　</servlet-mapping>
 
如果不使用mvc:resource标签方式配置配置就需要这么配置, 下面是配置多个静态资源交由tomcat容器也是处理静态资源访问的第三种方式:
　　<servlet>
        <servlet-name>Dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Dispatcher</servlet-name>
        <url-pattern>/index</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>Dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.gif</url-pattern>
    </servlet-mapping>

根据不同的资源文件制定不同的映射机制,其中servlet-name在tomcat中默认是default,
该servlet在tomcatconfigweb.xml文件中默认配置，不同的应用服务器对应的静态资源文件处理的servlet名称不尽相同，如下：

　　tomcat,jboss,glassfish,jetty : defaut;  

　　weblogic  : 　　　　　　　　　 FileServlet;  

　　websphere : 　　　　　　　　　 SimpleFileServlet;  

　　resin 　　: 　　　　　　　　　 resin-file;  

　　GAE  　　 : 　　　　　　　　　 _ah_default

TestController.java

package cn.zjx.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class TestController {
    @RequestMapping(value="/insert")
    public String save(){
        System.out.println("insert success");
        return "user_manager";
    }
    @RequestMapping(value="/selectList")
    public String selectList(HttpServletRequest requset){
        request.setAttribute("size", "5个用户");
        return "user_manager";
    }
}

8.启动tomcat 可以看到加载顺序与加载的文件以及实例化的testController对象及方法的url映射名称和静态资源映射;

静态资源可以访问

虽然web.xml中url-pattern为/

<servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
             <param-name>namespace</param-name>
             <param-value>spring-webmvc-dispatcher-servlet</param-value>
         </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
但是有它:
<mvc:resources mapping="/resource/images/**" location="/resource/images/" cache-period="31556926"/>

测试insert方法
http://localhost:6661/zjx-springmvc/insert

测试selectList查询方法
http://localhost:6661/zjx-springmvc/selectList

--------------------------------------------------------------------------------------------------
先到这里

接下来是配置velocity和log4j日志配置Dobble

然后通过maven命令来生成分布式项目结构如下结构把架构移植到下面就是spring-mvc为控制器的分布式架构了(^o^)/~
