1.基本環境搭建

spring簡介

SpringMVC框架是以請求為驅動，圍繞Servlet設計，將請求發給控制器，然后通過模型對象，分派器來展示請求結果視圖。其中核心類是DispatcherServlet，它是一個Servlet，頂層是實現的Servlet接口。

project創建

在圖中填上項目名稱即可，其他直接next

如上圖所示，創建兩個包，并且指定包的類型，如下圖，java包指定為Sources Root,resouces包指定為Resources root

整個目錄結構：

pom依賴

<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> <spring.version>4.3.18.RELEASE</spring.version> <mysql.version>5.1.48</mysql.version> <servlet.version>3.0-alpha-1</servlet.version> <commons-codec.version>1.9</commons-codec.version> <commons-dbcp.version>1.4</commons-dbcp.version> <jetty.version>8.1.8.v20121106</jetty.version> <slf4j.version>1.7.5</slf4j.version> <testng.version>6.8.7</testng.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.3.18.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version> 1.4</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>3.0-alpha-1</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.2</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.4</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>6.14.3</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> </dependencies>

2.

1.domain 實體類

package domain;public class User { private String username; private String password; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; }}

2.dao層（實現了查詢和插入）

package dao;import domain.User;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.jdbc.core.JdbcTemplate;import org.springframework.stereotype.Repository; @Repository public class UserDao{ private JdbcTemplate jdbcTemplate; private final static String sql=' Select count(*) from user_name where username=? and password=? '; private final static String sqlInsert='insert into user_name(username,password) values (?,?)'; @Autowired public void setJdbcTemplate(JdbcTemplate jdbcTemplate) { this.jdbcTemplate = jdbcTemplate; } public int FindUser(String username,String password) { return jdbcTemplate.queryForObject(sql,new Object[]{username,password},Integer.class); } // public void InsertUser(String username,String password){ jdbcTemplate.update(sqlInsert, username,password); } }

3.service層

package service;import dao.UserDao;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service; @Service public class UserService { private UserDao userdao; @Autowired public void setUserDao(UserDao userdao) { this.userdao = userdao; } public boolean Match(String username,String password) { int count=userdao.FindUser(username,password); return count>0; } public void InsertUser(String username,String password){ userdao.InsertUser(username,password); } }

4.controller層（這里用的包名為web）

package web;import domain.User;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import service.UserService;import javax.servlet.http.HttpServletRequest; @Controller public class UserController { private UserService userService; @Autowired public void setUserService(UserService userService) this.userService = userService; } @RequestMapping(value = '/index.html') public String tologin() { return 'login'; } @RequestMapping(value = '/login') public ModelAndView login(HttpServletRequest request, User user){ boolean isValidUser=userService.Match(user.getUsername(),user.getPassword()); if (isValidUser){ request.getSession().setAttribute('User',user.getUsername()+':登錄成功'); return new ModelAndView('success'); }else{ return new ModelAndView('login'); } } @RequestMapping('/insert') public String InsertUser(User user, Model model){ userService.InsertUser(user.getUsername(),user.getPassword()); model.addAttribute('Insert','注冊成功'); return 'success1'; } @RequestMapping('/insertPage') public String InsertPage() { return 'register'; }}

3.xml配置

1.web.xml

<!DOCTYPE web-app PUBLIC '-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN' 'http://java.sun.com/dtd/web-app_2_3.dtd' ><web-app xmlns='http://java.sun.com/xml/ns/javaee' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd' version='3.0'> <display-name>Archetype Created Web Application</display-name> <display-name>Archetype Created Web Application</display-name> <!--配置Spring的監聽器，默認只加載WEB-INF目錄下的applicationContext.xml配置文件--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--設置配置文件的路徑--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.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>classpath:dispatcher-servlet.xml</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></web-app>

resource里面新建兩個spring xml文件

2.applicationContext.xmlspring的配置文件applicationContext.xml中的一些配置的作用。

<?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:tx='http://www.springframework.org/schema/tx' xmlns:aop='http://www.springframework.org/schema/aop' 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 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd' xmlns:context='http://www.springframework.org/schema/context' xmlns:p='http://www.springframework.org/schema/p'> <!--包掃描--> <context:component-scan base-package='dao'/> <context:component-scan base-package='service'/> <context:component-scan base-package='web'/> <!-- 配置數據源 --> <bean class='org.apache.commons.dbcp.BasicDataSource'> <property name='driverClassName'><value>com.mysql.jdbc.Driver</value></property> <property name='url'><value>jdbc:mysql://localhost:3306/web1</value></property> <property name='username'><value>root</value></property> <property name='password'><value>123</value></property> </bean> <!-- 配置Jdbc模板 --> <bean p:dataSource-ref='dataSource'/> <bean p:dataSource-ref='dataSource'/></beans>

3.dispatcher-servlet.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' xmlns:context='http://www.springframework.org/schema/context' xmlns:mvc='http://www.springframework.org/schema/mvc' xmlns:p='http://www.springframework.org/schema/p' xmlns:aop='http://www.springframework.org/schema/aop' xmlns:tx='http://www.springframework.org/schema/cache' 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd' > <context:component-scan base-package='dao'/> <context:component-scan base-package='service'/> <context:component-scan base-package='web'/> <mvc:annotation-driven/> <!--mvc視圖解析--> <bean class='org.springframework.web.servlet.view.InternalResourceViewResolver'> <property name='viewClass' value='org.springframework.web.servlet.view.JstlView'/> <property name='prefix' value='/WEB-INF/jsp/'/><!--設置JSP文件的目錄位置--> <property name='suffix' value='.jsp'/> <property name='exposeContextBeansAsAttributes' value='true'/> </bean> <!--如果不寫proxy-target-class='true'這句話也沒問題--> <aop:aspectj-autoproxy proxy-target- /></beans>

4.Jsp
