需求說明html
實現用戶經過數據庫驗證登陸需求。採用 Myeclipse+Tomcat 6.0+Mysql 5.0+JDK 1.6java
2.數據庫表mysql
開發所用是Mysql數據庫,僅僅創建單張用戶表T_USER,表結構例如如下:web
字段名稱spring |
數據類型sql |
字段描寫敘述數據庫 |
IDexpress |
intapache |
用戶編號spring-mvc |
USERNAME |
VARCHAR |
username |
PASSWORD |
VARCHAR |
用戶登陸password |
sql語句例如如下:
CREATE TABLE `t_user` (
`ID` int(11) NOT NULL auto_increment,
`USERNAME` varchar(255) default NULL,
`PASSWORD` varchar(255) default NULL,
PRIMARY KEY (`ID`)
);
3.構建源碼文件夾
5.各項Xml配置文件具體解釋
(1)web.xml文件(Tomcat使用)
server依據配置內容初始化 spring 框架。 springmvc 框架和 log4j 日誌框架<pre name="code" class="html"><?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" 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_2_5.xsd"> <!-- 應用程序名稱 --> <display-name>ISS</display-name> <!-- 應用程序描寫敘述說明性文字 --> <description>Spring,SpringMvc,Ibatis</description> <!-- ServletContext初始化參數 --> <context-param> <param-name>webAppRootKey</param-name> <param-value>spring_springmvc_ibatis.root</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/classes/log4j.properties</param-value> </context-param> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml</param-value> </context-param> <!-- 字符過濾,防止加入到數據庫的數據爲亂碼 --> <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> <!-- web權限配置 --> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置監聽器,用於初始化 --> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Servlet初始化參數,配置springmvc模塊 --> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/springmvc-servlet.xml</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置session存在時間 --> <session-config> <session-timeout>60</session-timeout> </session-config> <!-- 默認起始頁面 --> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 異常跳轉頁面 --> <error-page> <exception-type>java.lang.Exception</exception-type> <location>/WEB-INF/jsp/exception.jsp</location> </error-page> </web-app>

(4)jdbc.properties(數據源屬性文件)
數據源鏈接信息的源出處。眼下配置了三種數據庫Oracle,DB2和Mysql
# Database Connectivity # Oracle #driver = oracle.jdbc.driver.OracleDriver #url = jdbc:oracle:thin:@localhost:1521:oracl #username = scott #password = tiger # DB2 #driver = com.ibm.db2.jcc.DB2Driver #url = jdbc:db2://10.1.10.162:50000/mydb #username = root #password = root # Mysql driver = com.mysql.jdbc.Driver url = jdbc:mysql://localhost:3306/mydb?useUnicode=true&characterEncoding=utf-8 username = root password = 1234 initialPoolSize = 1 minPoolSize = 1 maxPoolSize =10

該文件主要負責指定sql映射文件,即與model層對象相應的映射文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN" "http://www.ibatis.com/dtd/sql-map-config-2.dtd"> <sqlMapConfig> <!-- 配置settings --> <settings lazyLoadingEnabled="true" useStatementNamespaces="false"/> <!-- 配置sql映射文件 --> <sqlMap resource="com/archie/model/User.xml"/> </sqlMapConfig>
依據包文件夾,可以看出分紅model層,dao層,service層和web層,另外附加test層,用於java環境測試
(1)model層(User.java+User.xml)
User.java代碼
package com.archie.model; public class User { private int id; private String username; private String password; public User(){ } public User(int id){ this.id = id; } public User(int id, String username){ this.id = id; this.username = username; } public User(String username, String password) { this.username = username; this.password = password; } public User(int id, String username, String password){ this.id = id; this.username = username; this.password = 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; } }User.xml 代碼 (model 層對象的 sql 映射文件 , 被 dao 層調用 , 本質是 sql 語句集合 , 所有相關的 sql 均於此 )
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd"> <sqlMap namespace="User"> <typeAlias alias="User" type="com.archie.model.User"/> <select id="findAllUser" resultClass="User" > select * from t_user </select> <select id="findUserByID" resultClass="User" parameterClass="int"> select * from t_user where id=#id# </select> <select id="getTotalCount" resultClass="int"> select count(*) from t_user </select> <select id="searchUsers" resultClass="User" parameterClass="User"> select * from t_user <dynamic prepend="where"> <!-- 模糊查詢,用$表示文本替換,而用#表示替換PrepareStatement中的?號 --> <isNotEmpty prepend="and" property="username"> (username like '%$username$%') </isNotEmpty> <isNotEmpty prepend="and" property="password"> (password like '%$password$%') </isNotEmpty> </dynamic> </select> <select id="findUserByNameAndPassword" resultClass="User" parameterClass="User"> select * from t_user where username=#username# and password=#password# </select> <insert id="insertUser" parameterClass="User"> insert into t_user(id,username,password) values(null,#username#,#password#) </insert> <update id="updateUser" parameterClass="User"> update t_user set username = #username#, password=#password# where id=#id# </update> <delete id="deleteUser" parameterClass="int"> delete from t_user where id=#id# </delete> <delete id="deleteUserByLike" parameterClass="User"> delete from t_user <dynamic prepend="where"> <!-- 模糊查詢,用$表示文本替換,而用#表示替換PrepareStatement中的?號 --> <isNotEmpty prepend="and" property="username"> (username like '%$username$%') </isNotEmpty> <isNotEmpty prepend="and" property="password"> (password like '%$password$%') </isNotEmpty> </dynamic> </delete> </sqlMap> (2)dao層(數據服務層,BaseDao.java+UserDao.java) BaseDao.java(公共Dao,其它Dao均繼承它) package com.archie.dao; import javax.annotation.PostConstruct; import javax.annotation.Resource; import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport; import com.ibatis.sqlmap.client.SqlMapClient; public class BaseDao extends SqlMapClientDaoSupport { @Resource(name="sqlMapClient") //經過bean名稱注入 private SqlMapClient sqlMapClient; @PostConstruct //完畢sqlMapClient初始化工做 public void initSqlMapClient(){ super.setSqlMapClient(sqlMapClient); } }
package com.archie.dao; import java.util.List; import org.springframework.stereotype.Component; import com.archie.model.User; @Component //將UserDao類注入到bean裏面 public class UserDao extends BaseDao { public boolean addUser(User user) throws Exception{ User bean = (User)getSqlMapClientTemplate().insert("insertUser", user); return bean != null ? true : false; } public boolean deleteUser(int id) throws Exception{ int result = getSqlMapClientTemplate().delete("deleteUser", id); return result > 0 ? true : false; } public User getUserById(int id) throws Exception{ return (User)getSqlMapClientTemplate().queryForObject("findUserByID", id); } @SuppressWarnings("unchecked") public List getAllUsers() throws Exception{ return getSqlMapClientTemplate().queryForList("findAllUser"); } public boolean updateUser(User user) throws Exception{ int result = getSqlMapClientTemplate().update("updateUser", user); return result > 0 ? true : false; } public User getUserByNameAndPassword(User user) throws Exception{ return (User)getSqlMapClientTemplate().queryForObject("findUserByNameAndPassword", user); } public int getTotalCount() throws Exception{ return (Integer)getSqlMapClientTemplate().queryForObject("getTotalCount"); } @SuppressWarnings("unchecked") public List getUsersByLike(User user) throws Exception{ return getSqlMapClientTemplate().queryForList("searchUsers", user); } public int deleteUserByLike(User user) throws Exception{ int result = getSqlMapClientTemplate().delete("deleteUserByLike", user); if (result > 0) { System.out.println("模糊刪除成功。"); }else { System.out.println("沒有匹配的記錄1"); } return result; } }
UserService.java代碼例如如下
package com.archie.service; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Component; import org.springframework.transaction.annotation.Transactional; import com.archie.dao.UserDao; import com.archie.model.User; @Component //將UserService類注入到bean裏面 @Transactional //注入事務管理 public class UserService { @Resource(name="userDao") // 經過名稱注入到bean裏面 private UserDao userDao; public User login(User user) throws Exception{ return userDao.getUserByNameAndPassword(user); } public void addUser(User user) throws Exception{ userDao.addUser(user); } public void deleteUser(int id) throws Exception{ boolean bool = userDao.deleteUser(id); if (!bool) { System.out.println("刪除的記錄不存在!"); throw new RuntimeException(); } } public User getUserById(int id) throws Exception{ User user = userDao.getUserById(id); if (user == null) { return null; } return userDao.getUserById(id); } public void updateUser(User user) throws Exception{ userDao.updateUser(user); } public int getTotalCount() throws Exception{ return userDao.getTotalCount(); } @SuppressWarnings("unchecked") public List getUsersByLike(User user) throws Exception{ return userDao.getUsersByLike(user); } public int deleteUserByLike(User user) throws Exception{ return userDao.deleteUserByLike(user); } public void insertUsers(List<User> list) throws Exception{ for (int i = 0; i < list.size(); i++) { if (i > 3) { System.out.println("列表太長,中斷事務"); throw new RuntimeException("中斷事務異常,當列表長度大於3的時候有益拋出。看看事務是否回滾"); } User user = list.get(i); userDao.addUser(user); } } }
UserController.java
package com.archie.web; import javax.annotation.Resource; import javax.servlet.http.HttpSession; import javax.validation.Valid; import org.springframework.stereotype.Controller; import org.springframework.validation.BindingResult; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import com.archie.model.User; import com.archie.service.UserService; @Controller @RequestMapping("/user/*") public class UserController { @Resource(name="userService") private UserService userService; private final String LIST="redirect:/detail"; /** * 登陸 * @param user * @param session * @return */ @RequestMapping("/login") public ModelAndView login(@Valid User user,BindingResult result,HttpSession session) throws Exception{ if(!result.hasErrors()){ User loginUser=userService.login(user); if(loginUser!=null){ session.setAttribute("USER", loginUser); return new ModelAndView(LIST); }else{ return new ModelAndView("redirect:/"); } }else{ ModelAndView view=new ModelAndView(); view.setViewName("redirect:/"); view.addObject("error", result.getAllErrors()); return view; } } /** * 跳轉至加入頁 * @return */ @RequestMapping(value="/toAdd",method=RequestMethod.GET) public ModelAndView toAdd(){ return new ModelAndView("user/add"); } /** * 保存 * @param user * @return */ @RequestMapping(value="/add",method=RequestMethod.POST) public ModelAndView add(@Valid User user,BindingResult result) throws Exception{ if(result.hasErrors()){ return new ModelAndView("user/add","error", result.getAllErrors()); }else{ userService.addUser(user); return new ModelAndView(LIST); } } /** * 依據ID刪除 * @param id * @return */ @RequestMapping(value="/delete/{id}") public ModelAndView delete(@PathVariable int id) throws Exception{ userService.deleteUser(id); return new ModelAndView(LIST); } /** * 跳轉至編輯頁面 * @param id * @return */ @RequestMapping(value="/edit/{id}") public ModelAndView edit(@PathVariable int id) throws Exception{ User user=userService.getUserById(id); return new ModelAndView("user/edit","user",user); } /** * 編輯 * @param user * @return */ @RequestMapping(value="/edit") public ModelAndView update(@Valid User user,BindingResult result)throws Exception{ ModelAndView view=new ModelAndView(); if(result.hasErrors()){ view.addObject("error", result.getAllErrors()); view.setViewName("user/edit"); return view; }else{ userService.updateUser(user); return new ModelAndView(LIST); } } }
(5)test層(Java環境下測試)
TestUserController.java
