一转眼,毕业已经四个月了,回忆大学的点点滴滴,不由的想起了之前毕设做的东西,当时的项目是采用struts2+spring+mybatis框架开发的一个管理系统,整个项目的框架是由一个学长帮我们搭建好的,当时对于我这个刚接触java的童鞋,那样的东西感觉还是很新鲜的。利用空余时间,自己也使用struts2+spring+mybatis框架写个实现增删改查功能的例子。
不扯那么多了,进入正题。
首先,导入相关的jar包(后面附源码)
其次,创建并编写配置文件
ApplicationContext.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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> <aop:aspectj-autoproxy proxy-target-class="true" /> <!-- dataSource --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost:3306/testSSM?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull"></property> <property name="username" value="root"></property> <property name="password" value="root"></property> <property name="maxActive" value="100"></property> <property name="maxIdle" value="30"></property> <property name="maxWait" value="500"></property> <property name="defaultAutoCommit" value="true"></property> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- dao --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="typeAliasesPackage" value="com.wporoad.app.entity" /> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.wporoad.app.dao" /> </bean> <bean id="userService" class="com.wporoad.app.serviceImpl.UserServiceImpl"> <property name="userMapper" ref="userMapper" /> </bean> <bean id="userAction" class="com.wporoad.app.web.UserAction"> <property name="userService" ref="userService" /> </bean> </beans>
数据源和映射文件都在ApplicationContext.xml进行配置
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/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" version="2.5"> <context-param> <param-name>webAppRootKey</param-name> <param-value>ssi.root</param-value> </context-param> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> <init-param> <param-name>actionPackages</param-name> <param-value>com.cstor.network.action</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:resource/applicationContext*.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/classes/resource/log4j.properties</param-value> </context-param> <context-param> <param-name>log4jRefreshInterval</param-name> <param-value>60000</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> </web-app>
struts.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.custom.i18n.resources" value="message"></constant> <package name="struts2" extends="struts-default"> <action name="user_add" class="com.wporoad.app.web.UserAction" method="addUser" > <result name="success">/WEB-INF/page/success.jsp</result> <result name="error">/error.jsp</result> </action> <action name="user_list" class="com.wporoad.app.web.UserAction" method="queryUsers" > <result name="success">/WEB-INF/page/success.jsp</result> <result name="error">/error.jsp</result> <result name="list">/WEB-INF/page/UserList.jsp</result> </action> <action name="user_del" class="com.wporoad.app.web.UserAction" method="delUser" > <result name="list">/WEB-INF/page/UserList.jsp</result> <result name="error">/WEB-INF/page/error.jsp</result> </action> <action name="user_detail" class="com.wporoad.app.web.UserAction" method="detailUser" > <result name="success">/WEB-INF/page/success.jsp</result> <result name="error">/WEB-INF/page/error.jsp</result> <result name="detail">/WEB-INF/page/detail.jsp</result> </action> <action name="user_update" class="com.wporoad.app.web.UserAction" method="update" > <result name="success">/WEB-INF/page/success.jsp</result> <result name="error">/WEB-INF/page/error.jsp</result> <result name="update">/WEB-INF/page/update.jsp</result> </action> <action name="update" class="com.wporoad.app.web.UserAction" method="updateUser" > <result name="success">/WEB-INF/page/success.jsp</result> <result name="error">/WEB-INF/page/error.jsp</result> </action> </package> </struts>
接下来就是编写后台程序了
1.辅助类
package com.wporoad.app.entity; import java.io.Serializable; public class User implements Serializable { /** * */ private static final long serialVersionUID = 1L; private String id; private String userName; private String password; private String email; public String getId() { return id; } public void setId(String 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; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } }
2. action类UserAction
package com.wporoad.app.web; import java.util.List; import java.util.UUID; import javax.servlet.http.HttpServletRequest; import org.apache.log4j.Logger; import org.apache.struts2.ServletActionContext; import com.opensymphony.xwork2.ActionSupport; import com.wporoad.app.entity.User; import com.wporoad.app.service.UserService; public class UserAction extends ActionSupport { private static final long serialVersionUID = 1L; private static Logger logger = Logger.getLogger(UserAction.class); public UserService userService; public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } private String id; public String getId() { return id; } private String userName; private String password; private String email; /** * 添加用户信息 * * @return */ public String addUser() { User user = new User(); try { String iid = UUID.randomUUID().toString(); user.setId(iid); user.setUsername(userName); user.setPassword(password); user.setEmail(email); userService.addUser(user); } catch (Exception e) { logger.error("exception in add user", e); return ERROR; } return SUCCESS; } /** * 从数据库中获得所有的用户信息 * * @return */ public String queryUsers() { try { List<User> userList = userService.queryUsers(); HttpServletRequest request = ServletActionContext.getRequest(); request.setAttribute("list", userList); return "list"; } catch (Exception e) { logger.error("Exception in queryUsers", e); return ERROR; } } /** * 删除用户信息 * * @return */ public String delUser() { try { userService.delUser(id); List<User> userList = userService.queryUsers(); HttpServletRequest request = ServletActionContext.getRequest(); request.setAttribute("list", userList); } catch (Exception e) { logger.error("Exception in delUser", e); return ERROR; } return "list"; } public String detailUser() { try { List<User> userList = userService.detailUser(id); User user = userList.get(0); HttpServletRequest request = ServletActionContext.getRequest(); request.setAttribute("user", user); return "detail"; } catch (Exception e) { logger.error(e); return ERROR; } } public String update() { List<User> userList = userService.detailUser(id); User user = userList.get(0); HttpServletRequest request = ServletActionContext.getRequest(); request.setAttribute("user", user); return "update"; } public String updateUser() { try { User user = new User(); user.setId(id); user.setUsername(userName); user.setPassword(password); user.setEmail(email); userService.updateUser(user); return SUCCESS; } catch (Exception e) { logger.error(e); return ERROR; } } public void setId(String id) { this.id = id; } public void setUserName(String userName) { this.userName = userName; } public void setPassword(String password) { this.password = password; } public void setEmail(String email) { this.email = email; } }
3.service层,UserService接口和UserServiceImpl
UserService.java
package com.wporoad.app.service; import java.util.List; import com.wporoad.app.entity.User; public interface UserService { /** * 添加用户 * * @param user */ public void addUser(User user); /** * 列出所有的用户 * * @return */ public List<User> queryUsers(); /** * 删除用户 * * @param id */ public void delUser(String id); /** * 详细信息 * * @param id */ public List<User> detailUser(String id); /** * 修改信息 * * @param User */ public void updateUser(User User); }
UserServiceImpl.java
package com.wporoad.app.serviceImpl; import java.util.List; import com.wporoad.app.dao.UserMapper; import com.wporoad.app.entity.User; import com.wporoad.app.service.UserService; public class UserServiceImpl implements UserService { private UserMapper userMapper; public UserMapper getUserMapper() { return userMapper; } public void setUserMapper(UserMapper userMapper) { this.userMapper = userMapper; } /** * 添加用户 */ public void addUser(User user) { userMapper.addUser(user); } /** * 列出所有用户 */ public List<User> queryUsers() { List<User> userList = userMapper.queryUsers(); return userList; } /** * 删除用户 */ public void delUser(String id) { userMapper.delUser(id); } public List<User> detailUser(String id) { return userMapper.detailUser(id); } @Override public void updateUser(User User) { userMapper.updateUser(User); } }
4. Dao层UserMapper.java和映射文件UserMaper.xml
UserMapper.java
package com.wporoad.app.dao; import java.util.List; import com.wporoad.app.entity.User; public interface UserMapper { /** * 添加用户 * @param user */ public void addUser(User user); /** * 列出所有用户 * @return */ public List<User> queryUsers(); /** * 删除用户 * @param id */ public void delUser(String id); /** * 详细信息 * @param id */ public List<User> detailUser(String id); /** * 修改信息 * @param User */ public void updateUser(User User); }
UserMapper.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.wporoad.app.dao.UserMapper"> <resultMap id="UserMap" type="com.wporoad.app.entity.User"> <result property="id" column="ID" /> <result property="userName" column="USERNAME" /> <result property="password" column="PASSWORD" /> <result property="email" column="EMAIL" /> </resultMap> <insert id="addUser" parameterType="User"> INSERT INTO USER( ID, USERNAME, PASSWORD, EMAIL ) VALUES ( #{id}, #{userName}, #{password}, #{email} ) </insert> <select id="queryUsers" resultMap="UserMap" > SELECT * FROM USER </select> <!-- 删除信息 --> <delete id="delUser" parameterType="string"> DELETE FROM USER WHERE ID = #{id} </delete> <select id="detailUser" parameterType="String" resultMap="UserMap"> SELECT USERNAME,PASSWORD,EMAIL, ID FROM USER WHERE ID = #{value} </select> <!-- 更新信息 --> <update id="updateUser" parameterType="User"> UPDATE USER <set> <if test="userName != null ">USERNAME = #{userName},</if> <if test="password != null ">PASSWORD = #{password},</if> <if test="email != null ">EMAIL = #{email}</if> </set> WHERE ID = #{id} </update> </mapper>
下面就是几个页面了

ok,整个项目就是这样的。
