SpringMVC框架搭建环境

SpringMVC框架搭建环境步：建一个web项目二步：加上spring支持加入3.0版本（前四个夹包+sping.3.0-web一夹包,共五个）。三步：完成搭建。（SpringMVC实现的过程.加入Spring支持org.springframework,web-3・0.1・RELEASE-A,jarorg.springframework.web.servlet-3・0.1・RELEASE-A,jarcommons.logging-1.1.1・jar.配置web.xml原因是为了下一步做准备需要用到这里的servlet中的名字来建立xml文件进行关联.创建myspringMvc-servlet・xml文件.加入Spring上下文支持1》创建Context命名空间2》引入支持配置扫描包<context:component-scanbase-package="类包"></context:component-scan>.建立控制器类--MyController）四步：配置web.xml如下：<?xmlversion="1.0"encoding="UTF-8"?><web-appversion="2.5"xmlns="/xmL/ns/javaee"xmlns:xsi="/2001/XMLSchema-instance"xsi:schemaLocation="/xmL/ns/javaee/xmL/ns/javaee/web-app_2_5.xsd"><display-name></display-name><welcome-file-list><welcome-file>index・jsp</welcome-file></welcome-file-list><servlet><servlet-name>myspringMvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param> \<param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></init-param</init-param></servlet><servlet-mapping>六步：访问方法：如下:六步：访问方法：如下:1.添加注解:©Controller@RequestMappin1.添加注解:©Controller@RequestMappin("/|myContro") //http://localhost:8080/项目名字//方法名：一样任意定义七步：传递是三种方式：.普通的参数传递(从页面拿值)：例如下：@RequestMapping(value="/method2")publicStringmethod2(@RequestParam("name")Stringn,@RequestParam("age")inta){System.out.println("用户名"+n); “/”不能掉return"/result.jsp";.对象传递(有实体类)@RequestMapping(value="/method3")publicStringmethod3(Useruser){System.out.println("用户名"+user.getName());System.out.println("年龄"+user.getAge());return"/result.jsp";}.通过servletAPI进行传值|@RequestMapping(value="/method4")publicStringmethod4(Useruser,HttpServletRequestrequest,HttpSessionsession){System.out.println("用户名"+user.getName());System.out.println("年龄"+user.getAge());〃保存数据request.setAttribute("u",user);session.setAttribute("name",user.getName());〃创建Application对象ServletContextappliaction=session.getServletContext();appliaction.setAttribute("age",user.getAge());//return"/result2.jsp";代表的就是转发 return"redirect:../result2.jsp";重定向}第二种：配置文件：一步：建一个web项目二步：加上Spring支持加入3.0版本(前四个夹包+sping.3.0-web-----夹包,共五个)。三步：完成搭建。四步：配置web.xml如下：<?xmlversion="1.0"encoding="UTF-8"?><web-appversion="2.5"xmlns="http:"/xml/ns/javaee"xmlns:xsi="http:〃/2001/XMLSchema-instance”xsi:schemaLocation="/xml/ns/javaee/xml/ns/javaee/web-app_2_5.xsd">

<display-name></display-name><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><servlet><servlet-name>myspringMvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>在web.xml在web.xml由此节点，此时就不需要再创建myspringMvc-servlet.xml文件，次是需要在applicationContext.xml文件中直接配置<param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>myspringMvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>四步：配置applicationContext.xml如下:在applicationContext.xml文件配置如下:<?xmlversion="1.0"encoding="UTF-8”?><beansxmlns="http:〃/schema/beans”xmlns:xsi="http:〃/2001/XMLSchema-instance“xmlns:p="/schema/pxmlns:context="/schema/context"xsi:schemaLocation="/schema/beans/schema/beans/spring-beans-3.0.xsd/schema/context/schema/context/spring-context-3.0.xsd"><!--配置自动扫描包--><context:component-scanbase-package="com.controller"></context:component-scan><!--处理文件上传--><beanid="multipartResolver"class="mons.CommonsMultipartResolver"><propertyname="defaultEncoding“value="gbk"/><!--默认编码(ISO-8859-1)--><propertyname="maxInMemorySize“value="10240”/><!--最大内存大小(10240)--><propertyname="uploadTempDir“value="/upload/"/><!--上传后的目录名(WebUtils#TEMP_DIR_CONTEXT_ATTRIBUTE)--><propertyname="maxUploadSize“value="-1"/><!--最大文件大小，-1为无限止(-1)--></bean></beans>文件上传：1.先在webroot下面建一个文件夹如：/upload文件上jsp页面提交表单如下：<formaction="myContro/method5"method="post"enctype="multipart/form-data">文件名<inputtype="file"name="img"><br><inputtype="submit"value="登陆"></form>SpringMVC文件上传：@RequestMapping(value="/method5")publicStringmethod5(@RequestParam("img")CommonsMultipartFilefile){〃拿到上传的路径StringuploadPath二application.getRealPath("/upload");//获取文件原始的名称StringfileName二file.getOriginalFilename();StringfilePath二uploadPath+File.separator+fileName;//服务器访问图片的径Fileufile=newFile(filePath);try{file.getFileItem().write(ufile);}catch(Exceptione){e.printStackTrace();}return"/succ.jsp";}publicvoidsetServletContext(ServletContextarg0){this.application二arg0;}久：SpringMVC配置乱码处理web.xml中<!--配置监听器--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!--配置乱码处理--><filter><filter-name>CharacterEncoding</filter-name><filter-class
