搭建Spring、Spring MVC、Mybatis和Freemarker
1、pom文件
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.candle</groupId><artifactId>home-finance-sample</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>home-finance-sample Maven Webapp</name><url>http://maven.apache.org</url><build><finalName>home-finance-sample</finalName></build><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><!-- spring jar --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>3.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>3.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>3.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>3.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>3.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>3.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>3.2.6.RELEASE</version></dependency><!-- spring mvc jar --><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>3.2.6.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>3.2.6.RELEASE</version></dependency><!-- mybatis jar --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.2.4</version></dependency><!-- mybatis-spring jar --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.2.2</version></dependency><!-- mysql-connector-java jar --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.28</version></dependency><!-- 数据库连接池 jar --><dependency><groupId>commons-dbcp</groupId><artifactId>commons-dbcp</artifactId><version>1.4</version></dependency><dependency><groupId>commons-pool</groupId><artifactId>commons-pool</artifactId><version>1.6</version></dependency><!-- log jar --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>1.7.5</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.5</version></dependency><!-- jsp Template jar --><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.20</version></dependency><!-- apache servlet api jar --><dependency><groupId>org.apache.tomcat</groupId><artifactId>servlet-api</artifactId><version>6.0.37</version></dependency></dependencies></project>
2、web.xml配置文件
<?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_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>Archetype Created Web Application</display-name><!-- Spring 配置文件路径，此处可将Spring MVC的相关配置内容配置到Spring的配置文件applicationContext.xml中，共享同一个配置文件即可 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:applicationContext.xml</param-value></context-param><!-- Spring 监听器 配置 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><listener-class>org.springframework.web.context.request.RequestContextListener</listener-class></listener><!-- 字符集 过滤器 --><filter><filter-name>CharacterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>CharacterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- Spring mvc 配置，配置文件名称默认为{servlet-name}-servlet.xml，路径默认在/WEB-INF/下 --><servlet><servlet-name>springmvc</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>
3、Spring MVC 配置文件，路径在/WEB-INF/下，springmvc-servlet.xml，里面包括freemarker的配置内容
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd" ><context:component-scan base-package="com.hf.controller" /> <mvc:annotation-driven /><!-- <beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/views" /><property name="suffix" value=".jsp" /></bean> --><mvc:resources mapping="/**" location="/"/><!-- ===================================================== --><!-- ViewResolver For FreeMarker --><!-- ===================================================== --><bean id="freemarkerResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"><property name="order" value="1" /><property name="suffix" value=".ftl" /><property name="contentType" value="text/html;charset=utf-8" /><property name="viewClass"><value>org.springframework.web.servlet.view.freemarker.FreeMarkerView</value></property></bean><!-- ===================================================== --><!-- ViewResolver For FreeMarkerConfigurer --><!-- ===================================================== --><bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"><property name="templateLoaderPath"><value>/views/</value></property><property name="freemarkerSettings"><!-- 设置FreeMarker环境属性 --><props><prop key="template_update_delay">5</prop><!--刷新模板的周期，单位为秒 --><prop key="default_encoding">UTF-8</prop><!--模板的编码格式 --><prop key="locale">UTF-8</prop><!-- 本地化设置 --><prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop><prop key="time_format">HH:mm:ss</prop><prop key="number_format">0.####</prop><prop key="boolean_format">true,false</prop><prop key="whitespace_stripping">true</prop><prop key="tag_syntax">auto_detect</prop><prop key="url_escaping_charset">UTF-8</prop></props></property></bean></beans>
4、applicationContext.xml，此处省略dataSource.properties配置的数据库连接的内容
<?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:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"><!-- 扫描com.hf包里下的所有class文件，配置注解的类全都装入容器中进行管理 --><context:component-scan base-package="com.hf" /><!-- 添加注解驱动 --><mvc:annotation-driven /><!-- 引入jdbc配置文件 --><context:property-placeholder location="classpath:dataSource.properties" /><!--创建jdbc数据源 --><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"><property name="driverClassName" value="${driver}" /><property name="url" value="${url}" /><property name="username" value="${username}" /><property name="password" value="${password}" /></bean><!-- 配置事务管理 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!-- 创建SqlSessionFactory，并指定数据源 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="configLocation" value="classpath:mybatis-config.xml" /><property name="dataSource" ref="dataSource" /></bean><!-- Mapper文件扫描配置工具，Spring将自动扫描对应配置路径下的Mapper --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="classpath:" /></bean><!-- MapperFactoryBean 创建的代理类实现了IUserDAO接口,并且注入到应用程序中，这样不用写实现类 --><bean id="userDAO" class="org.mybatis.spring.mapper.MapperFactoryBean"><property name="mapperInterface" value="com.hf.idao.IUserDAO" /><property name="sqlSessionFactory" ref="sqlSessionFactory" /></bean></beans>
5、Mybatis的相关配置文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTDConfig 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><!-- 配置映射文件 --> <configuration><mappers><!--映射文件--><mapper resource="user.xml"/></mappers> </configuration>
映射文件，user.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.hf.idao.IUserDAO"><resultMap type="com.hf.model.UserDo" id="UserDo" autoMapping="true"> <id property="id" column="id"/> <result property="username" column="username"/><result property="password" column="password"/> </resultMap> <select id="findAllUser" resultMap="UserDo"> select * from w_user </select> </mapper>
6、业务代码
model层
package com.hf.model;import java.io.Serializable;public class UserDo implements Serializable {private int id ;private String username ;private String password ;public int getId() {return id;}public void setId(int id) {this.id = id;}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;}}
dao层
package com.hf.idao;import java.util.List;import com.hf.model.UserDo;public interface IUserDAO {public List<UserDo> findAllUser() ; }
service层
package com.hf.iservice;import java.util.List;import com.hf.model.UserDo;public interface IUserService {public List<UserDo> findAllUser() ; }
package com.hf.service;import java.util.List;import javax.annotation.Resource;import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;import com.hf.idao.IUserDAO; import com.hf.iservice.IUserService; import com.hf.model.UserDo;@Service("userService") public class UserService implements IUserService {@Autowiredprivate IUserDAO userDAO ;@Overridepublic List<UserDo> findAllUser() {return userDAO.findAllUser();}}
controller层
package com.hf.controller;import java.util.List;import javax.annotation.Resource;import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping;import com.hf.iservice.IUserService; import com.hf.model.UserDo;@Controller public class UserController {@Autowiredprivate IUserService userService ;@RequestMapping("/User/helloUser")public String helloUser(ModelMap modelMap) {List<UserDo> list = this.userService.findAllUser();modelMap.addAttribute("userDo", list) ;return "/user_list";} }
views层文件user_list.ftl：
<#setting classic_compatible=true> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>User List</title> <style type="text/css"> <!-- .STYLE1 {font-family: Arial, Helvetica, sans-serif;font-weight: bold;font-size: 36px;color: #FF0000; } .STYLE13 {font-size: 24} .STYLE15 {font-family: Arial, Helvetica, sans-serif; font-size: 24px; } --> </style> </head><body> <table width="1500" height="600" border="0" cellpadding="0" cellspacing="0"><tr><td width="500" height="200"> </td><td width="500" height="200" align="center" valign="middle"><div align="center"><span class="STYLE1">User List </span></div></td><td width="500" height="200"> </td></tr><tr><td width="500" height="200"> </td><td width="500" height="200"><table width="500" height="200" border="1" cellpadding="0" cellspacing="0"><tr><td width="160" height="65" align="center" valign="middle"><span class="STYLE15">ID</span></td><td width="160" height="65" align="center" valign="middle"><span class="STYLE15">Username</span></td><td width="160" height="65" align="center" valign="middle"><span class="STYLE15">Password</span></td></tr><#list userDo as user><tr><td width="160" height="65" align="center" valign="middle"><span class="STYLE15">${user.id}</span></td><td width="160" height="65" align="center" valign="middle"><span class="STYLE15">${user.username}</span></td><td width="160" height="65" align="center" valign="middle"><span class="STYLE15">${user.password}</span></td></tr></#list></table></td><td width="500" height="200"> </td></tr><tr><td width="500" height="200"> </td><td width="500" height="200"> </td><td width="500" height="200"> </td></tr> </table> </body> </html>
