ssm框架整合 spring + springMVC + mybatis

废话不多，先来相关配置文件：

代码：实体类 User.java

package com.oa.bean;import java.io.Serializable;import java.util.Date;public class User implements Serializable{/*** */private static final long serialVersionUID = 1L;private int id;private String name;private String account;private String pwd;private String tel;private int age;private Date w_date;private Date j_date;private String role;private int dept_id;private int leval;public User(){}public User(int id, String name, String account, String pwd, String tel, int age, Date w_date, Date j_date,String role, int dept_id, int leval) {super();this.id = id;this.name = name;this.account = account;this.pwd = pwd;this.tel = tel;this.age = age;this.w_date = w_date;this.j_date = j_date;this.role = role;this.dept_id = dept_id;this.leval = leval;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getAccount() {return account;}public void setAccount(String account) {this.account = account;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public String getTel() {return tel;}public void setTel(String tel) {this.tel = tel;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public Date getW_date() {return w_date;}public void setW_date(Date w_date) {this.w_date = w_date;}public Date getJ_date() {return j_date;}public void setJ_date(Date j_date) {this.j_date = j_date;}public String getRole() {return role;}public void setRole(String role) {this.role = role;}public int getDept_id() {return dept_id;}public void setDept_id(int dept_id) {this.dept_id = dept_id;}public int getLeval() {return leval;}public void setLeval(int leval) {this.leval = leval;}}

DAO层的Mapper， 使用的是mybatis注解方式，因此不需要相对应的xml

package com.oa.dao;import java.util.List;import org.apache.ibatis.annotations.Delete;import org.apache.ibatis.annotations.Insert;import org.apache.ibatis.annotations.Param;import org.apache.ibatis.annotations.Select;import org.apache.ibatis.annotations.Update;import com.oa.bean.User;public interface UserMapper{@Select("select * from user where account=#{account} and pwd=#{pwd}")public User login(@Param("account")String account,@Param("pwd")String pwd);@Select("select * from user")public List<User> selectAll();@Select("select * from user where dept_id=#{dept_id}")public List<User> selectByID(@Param("dept_id") int dept_id);@Select("select * from user where id=#{id}")public User selectById(@Param("id")int id);@Select("select * from user where name=#{name}")public User selectByName(@Param("name") String name);@Select("select * from user where account=#{account}")public User selectByAccount(@Param("account") String account);@Insert("insert into user(name,account,pwd,tel,age,w_date,j_date,role,"+ "dept_id,leval)"+ " values(#{user.name},#{user.account},#{user.pwd},#{user.tel},"+ "#{user.age},#{user.w_date},"+ "#{user.j_date},#{user.role},#{user.dept_id},#{user.leval})")public void add(@Param("user")User user);@Update("update user set name=#{user.name},tel=#{user.tel},age=#{user.age},"+ "dept_id=#{user.dept_id},"+ "role=#{user.role},leval=#{user.leval} where id=#{user.id}")public void update(@Param("user")User user);@Update("update user set name=#{user.name},tel=#{user.tel},age=#{user.age},"+"pwd=#{user.pwd} where id=#{user.id}")public void updateInfo(@Param("user")User user);@Delete("delete from user where id=#{id}")public void deleteById(@Param("id")int id);@Delete("delete from user where name=#{name}")public void deleteByName(@Param("name")String name);@Update("update user set pwd=#{pwd} where id=#{id}")public void updatePwd(@Param("pwd")String pwd,@Param("id")int id);}

service层 userSrvice.java

package com.oa.service;import java.util.List;import com.oa.bean.User;public interface UserService {public User login(String account,String pwd);public List<User> selectAll();public User selectById(int id);public void updateInfo(User user);public User selectByName(String name);public User selectByAccount(String account);public void add(User user);public List<User> selectByID(int id);public void update(User user);public void deleteById(int id);public void deleteByName(String name);public void updatePwd(String pwd,int id);}

service实现类 UserSerciceImpl.java

package com.oa.service.Impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.oa.bean.User;import com.oa.dao.UserMapper;import com.oa.service.UserService;@Servicepublic class UserServiceImpl implements UserService {@Autowiredprivate UserMapper userMapper;@Overridepublic User login(String account, String pwd) {// TODO Auto-generated method stubreturn userMapper.login(account, pwd);}@Overridepublic List<User> selectAll() {// TODO Auto-generated method stubreturn userMapper.selectAll();}@Overridepublic User selectById(int id) {// TODO Auto-generated method stubreturn userMapper.selectById(id);}@Overridepublic User selectByName(String name) {// TODO Auto-generated method stubreturn userMapper.selectByName(name);}@Overridepublic User selectByAccount(String account) {// TODO Auto-generated method stubreturn userMapper.selectByAccount(account);}@Overridepublic void add(User user) {// TODO Auto-generated method stubuserMapper.add(user);}@Overridepublic void updateInfo(User user) {// TODO Auto-generated method stubuserMapper.updateInfo(user);}@Overridepublic void update(User user) {// TODO Auto-generated method stubuserMapper.update(user);}@Overridepublic void deleteById(int id) {// TODO Auto-generated method stubuserMapper.deleteById(id);}@Overridepublic void deleteByName(String name) {// TODO Auto-generated method stubuserMapper.deleteByName(name);}@Overridepublic void updatePwd(String pwd, int id) {// TODO Auto-generated method stubuserMapper.updatePwd(pwd, id);}@Overridepublic List<User> selectByID(int id) {// TODO Auto-generated method stubreturn userMapper.selectByID(id);}}

UserController.java

package com.oa.controller;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.servlet.ModelAndView;import com.oa.bean.User;import com.oa.service.UserService;@Controller@RequestMapping("/user")public class UserController {@Autowiredprivate UserService userService;@RequestMapping("/login")public ModelAndView login(String account,String pwd,HttpServletRequest request,HttpServletResponse response){ModelAndView modelAndView = new ModelAndView();if(account==null || pwd==null){modelAndView.addObject("msg", "用户名或密码不能为空");modelAndView.setViewName("login");return modelAndView;}if(userService.selectByAccount(account)==null){modelAndView.addObject("msg1", "用户名不存在");modelAndView.setViewName("login");return modelAndView;}User user = userService.selectByAccount(account);if(!user.getPwd().equals(pwd)){modelAndView.addObject("msg2", "用户名或密码错误");modelAndView.setViewName("login");return modelAndView;}request.getSession().setAttribute("user", user);request.getSession().setMaxInactiveInterval(1000*60*10);modelAndView.addObject("user", user);modelAndView.setViewName("info");return modelAndView;}@RequestMapping("/selectByName")@ResponseBodypublic User select(String name){if(userService.selectByName(name)==null){return null;}return userService.selectByName(name);}}

自定义的登录拦截器：

package com.oa.base;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;public class LoginInterceptor implements HandlerInterceptor {@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)throws Exception {// TODO Auto-generated method stubHandlerInterceptor.super.afterCompletion(request, response, handler, ex);}@Overridepublic void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,ModelAndView modelAndView) throws Exception {// TODO Auto-generated method stubHandlerInterceptor.super.postHandle(request, response, handler, modelAndView);}//登录校验拦截器@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)throws Exception {/** 对所有 "/user/**"路径的请求，进行登录校验，* 如果session中存有user对象，则进行放行，反之返回 登录页面*/System.out.println(request.getRequestURI());System.out.println(request.getSession().getAttribute("user"));if(!request.getRequestURI().contains("/login")){if(request.getSession().getAttribute("user")==null){response.sendRedirect("/oa/login.jsp");return false;}}return true;}}

由于某些原因，以上只是项目中完整的一条线，dao层、service层、controller层以及配置文件均完整可以运行。

欢迎大家提出宝贵意见，鄙人很希望能有机会向各位大神学习
