二、Spring、SpringMVC的配置

1.引入Spring、SpringMVC的jar包

在pom.xml中添加如下依赖：

  <version>0.0.1-SNAPSHOT</version><name>maven Maven Webapp</name><url>http://maven.apache.org</url><dependencies><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.3.0.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.0.RELEASE</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>3.0-alpha-1</version></dependency></dependencies><build><finalName>maven</finalName></build>

maven会帮我们下载jar包，其jar为：

2.建立包结构、配置文件

    配置web.xml

<?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"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>maven</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></context-param><filter><description>字符集过滤器</description><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><description>字符集编码</description><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><listener><description>spring监听器</description><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><servlet><description>spring mvc servlet</description><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><description>spring mvc 配置文件</description><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list>	
</web-app>

  在spring.xml文件中 ，配置需要扫描的包

	<!-- 自动扫描与装配 --><context:component-scan base-package="best.dao.impl,best.service.impl" />

 在spring-mvc.xml文件中，配置：

	<!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 --><context:component-scan base-package="best.controller" /><!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"p:prefix="/WEB-INF/view/" p:suffix=".jsp"/>

写几个测试类

package best.controller;import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;import best.service.TestSerivceI;
import best.service.impl.TestServiceImpl;@Controller
@RequestMapping("/testController")
public class TestController extends BaseController{private  TestSerivceI testService;@Resourcepublic void setTestService(TestSerivceI testService) {this.testService = testService;}	@RequestMapping("/login")public String login(HttpServletRequest request) {return "login";}
}

此处login是转到WEB-INF下的view下的login.jsp ，另外使用的是8090端口，浏览器地址输入http://localhost:8090/maven/testController/login.do
