(1)web.xml文件(Tomcat使用)
服务器根据配置内容初始化spring框架，springmvc框架和log4j日志框架

(6)sqlMapConfig.xml(Ibatis框架配置文件)
该文件主要负责指定sql映射文件，即与model层对象对应的映射文件
<?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>
6.Java代码编写
根据包目录，可以看出分成model层,dao层,service层和web层,另外附加test层,用于java环境测试
(1)model层(User.java+User.xml)
User.java代码
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代码
(model层对象的sql映射文件,被dao层调用,本质是sql语句集合,所有相关的sql均于此)
<?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"> <!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 --> <isNotEmpty prepend="and" property="username"> (username like '%$username$%') </isNotEmpty> <isNotEmpty prepend="and" property="password"> (password like '%$password$%') </isNotEmpty> </dynamic> </select> <select id="findUserByNameAndPassword" resultClass="User" parameterClass="User"> select * from t_user where username=#username# and password=#password# </select> <insert id="insertUser" parameterClass="User"> insert into t_user(id,username,password) values(null,#username#,#password#) </insert> <update id="updateUser" parameterClass="User"> update t_user set username = #username#, password=#password# where id=#id# </update> <delete id="deleteUser" parameterClass="int"> delete from t_user where id=#id# </delete> <delete id="deleteUserByLike" parameterClass="User"> delete from t_user <dynamic prepend="where"> <!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 --> <isNotEmpty prepend="and" property="username"> (username like '%$username$%') </isNotEmpty> <isNotEmpty prepend="and" property="password"> (password like '%$password$%') </isNotEmpty> </dynamic> </delete> </sqlMap>
(2)dao层(数据服务层,BaseDao.java+UserDao.java)
BaseDao.java(公共Dao,其他Dao均继承它)
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") //通过bean名称注入 private SqlMapClient sqlMapClient; @PostConstruct //完成sqlMapClient初始化工作 public void initSqlMapClient(){ super.setSqlMapClient(sqlMapClient); } }
UserDao.java(user数据服务层)
package com.archie.dao; import java.util.List; import org.springframework.stereotype.Component; import com.archie.model.User; @Component //将UserDao类注入到bean里面 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("模糊删除成功！"); }else { System.out.println("没有匹配的记录1"); } return result; } }
(3)service层(业务服务层,UserService.java)
UserService.java代码如下
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 //将UserService类注入到bean里面 @Transactional //注入事务管理 public class UserService { @Resource(name="userDao") // 通过名称注入到bean里面 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("删除的记录不存在！"); 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("列表太长，中断事务"); throw new RuntimeException("中断事务异常,当列表长度大于3的时候故意抛出，看看事务是否回滚"); } User user = list.get(i); userDao.addUser(user); } } }
(4)web层(界面控制层,UserController.java)
UserController.java
package com.archie.web;</P><P>import javax.annotation.Resource; import javax.servlet.http.HttpSession; import javax.validation.Valid;</P><P>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;</P><P>import com.archie.model.User; import com.archie.service.UserService;</P><P>@Controller @RequestMapping("/user/*") public class UserController { @Resource(name="userService") private UserService userService; private final String LIST="redirect:/detail"; /** * 登录 * @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; } } /** * 跳转至添加页 * @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); } } /** * 根据ID删除 * @param id * @return */ @RequestMapping(value="/delete/{id}") public ModelAndView delete(@PathVariable int id) throws Exception{ userService.deleteUser(id); return new ModelAndView(LIST); } /** * 跳转至编辑页面 * @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); } /** * 编辑 * @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); } } }
TestUserController.java
import java.util.ArrayList; import java.util.List; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.archie.model.User; import com.archie.service.UserService; public class TestUserController { public static void main(String[] args) throws Exception{ ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); UserService userService = (UserService)context.getBean("userService"); List<User> list = new ArrayList<User>(); list.add(new User("wang", "wang")); list.add(new User("wang", "wang")); list.add(new User("wang", "wang")); userService.insertUsers(list); System.out.println("恭喜恭喜，添加成功！"); userService.deleteUser(26); System.out.println("恭喜恭喜，删除成功！"); User beanUser = userService.getUserById(21); if (beanUser != null) { System.out.println("恭喜恭喜，查找成功！"); }else { System.out.println("不好意思，您所查找的用户不存在！"); } int totalCount = userService.getTotalCount(); System.out.println("TotalCount="+totalCount); int result = userService.deleteUserByLike(new User("wang","wang")); System.out.println("模糊删除的记录条数是："+result); List users = userService.getUsersByLike(new User("meimei","1234")); if (users == null || users.size() == 0) { System.out.println("没有匹配的记录2"); }else { for (int i = 0; i < users.size(); i++) { User user = (User)users.get(i); System.out.println("username="+user.getUsername()+",password="+user.getPassword()); } } System.out.println("length="+users.size()); } }
