springMVC 4.1 环境搭建

1)jar包准备，以下的jar包是从spring官网下载的，我下载的是 spring-framework-4.1.7.RELEASE-dist.zip 这个压缩包
  解压以后 D:\spring-framework-4.1.7.RELEASE\libs 中选择如下jar导入工程
   


 2）当然如果只用到以上的那些jar包是无法正确启动mvc环境的，至于还依赖哪些jar，下面再慢慢讲解(配置文件的命名和目录参考本文 第4点 中的截图 )
    准备好spring官网的jar以后就需要配置 web.xml 和 spring相关xml 

    

      a. web.xml配置如下

       ------------------------------------------------------------------------------------------------------
      

 <?xml version="1.0" encoding="UTF-8"?>       <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener> <context-param><param-name>contextConfigLocation</param-name><param-value>WEB-INF/config/spring*.xml</param-value></context-param>  <servlet>          <servlet-name>DispatcherServlet</servlet-name>          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>          <init-param>              <param-name>contextConfigLocation</param-name>              <param-value>WEB-INF/config/spring-mvc.xml</param-value>          </init-param>          <load-on-startup>1</load-on-startup>     </servlet>     <!-- URL映射 -->     <servlet-mapping>         <servlet-name>DispatcherServlet</servlet-name>         <url-pattern>/</url-pattern>     </servlet-mapping>     </web-app>

     -----------------------------------------------------------------------------------------------------------------


    b.spring-context.xml配置如下
     -----------------------------------------------------------------------------------------------------------------

<?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:aop="http://www.springframework.org/schema/aop"       xmlns:context="http://www.springframework.org/schema/context"   xmlns:util="http://www.springframework.org/schema/util"   xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans.xsd   http://www.springframework.org/schema/aop             http://www.springframework.org/schema/aop/spring-aop-4.1.xsd   http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context.xsd   http://www.springframework.org/schema/util   http://www.springframework.org/schema/util/spring-util-4.1.xsd"><context:component-scan base-package="com.ly"/><!-- 激活自动代理功能 -->    <aop:aspectj-autoproxy proxy-target-class="true"/>         </beans>

     -----------------------------------------------------------------------------------------------------------------


    c.spring-mvc.xml 配置如下：springMVC框架 需要jar包，在返回json数据时有用。
   （jackson-annotations-2.2.4.jar、jackson-core-2.2.3.jar、jackson-databind-2.2.3.jar）
     
    -----------------------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8"?><beans  xmlns="http://www.springframework.org/schema/beans"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/aop                http://www.springframework.org/schema/aop/spring-aop-4.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd"><context:component-scan base-package="com.ly.controller"></context:component-scan><aop:aspectj-autoproxy proxy-target-class="true"/><mvc:annotation-driven><mvc:message-converters register-defaults="true"><bean class="org.springframework.http.converter.StringHttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/plain;charset=UTF-8</value><value>text/html;charset=UTF-8</value></list></property></bean><bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">                    <property name="supportedMediaTypes">                        <list>                            <value>text/html; charset=UTF-8</value>                            <value>application/json;charset=UTF-8</value>                        </list>                    </property>             </bean></mvc:message-converters></mvc:annotation-driven><!--视图名称解析器--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"  p:order="100" p:viewClass="org.springframework.web.servlet.view.JstlView"  p:prefix="/WEB-INF/views/" p:suffix=".jsp" /></beans>

   -----------------------------------------------------------------------------------------------------------------


   3）其他jar包
     aopalliance-1.0.jar、asm-3.3.1.jar、aspectjweaver.jar、cglib-nodep-2.1_3.jar  AOP织入语法
     jstl.jar、standard-1.1.2.jar jsp页面显示用到
     log4j-1.2.15.jar、slf4j-api-1.5.8.jar、slf4j-log4j12-1.5.0.jar、commons-logging-1.1.1.jar 系统日志需要用到的jar
     剩余就是其他的功能需要的jar了


   4）springMVC+AOP环境jar包的全家福以及工程结构
                 
      


   5）controller层的简单示例
 
@Controller
@Scope("prototype")
@RequestMapping("/mvctest") 
public class TestController {
@Resource(name="testService")
private TestService testService;
@RequestMapping(value="/test1",method=RequestMethod.GET)
@ResponseBody
public ResultType etest1(@RequestParam(value="test") String test){
ResultType rs = new ResultType();
rs.setMessage("成功");
rs.setSuccess("1");
rs.setDate(testService.saveTest());
Map<String,Object> map = new HashMap<String,Object>();
map.put("test", rs);
return rs;
}
@RequestMapping(value="/test2",method=RequestMethod.GET)
public String test2(Model model){
String view = "index";
User user = new User();
user.setUserName("luoyi");
user.setAge(27);
model.addAttribute("userInfo",user);
return view;
}
}
