3、数据库表设计
-- 创建员工表
create table t_emp(
id int primary key auto_increment,
name varchar(20) not null,
salary double not null,
age int not null
)-- 添加员工数据
insert into t_emp values(null,'王恒杰',20000,21);
insert into t_emp values(null,'杨福君',9000,19);
-- 查询员工数据
select * from t_emp;-- 创建管理员表
create table t_admin(id int primary key auto_increment,username varchar(20),password varchar(50)
)
-- 添加数据
insert into t_admin values(null,'王恒杰','123456');
-- 查询
select * from t_admin
4、Maven导入项目所依赖的jar包

二、管理员登录/注册模块功能开发
-
功能模块:
登录,注册,注销,密码加密
-
注册示意图
登录示意图
1、dao层(adminDao.java)
public interface AdminDao {/*** 登录* @param admin* @return*/public Admin login(Admin admin);/*** 注册* @param admin*/public void register(Admin admin);
}
2、Service层
(1)adminService接口层
public interface AdminService {/*** 登录* @param admin* @return*/public Admin login(Admin admin);/*** 注册* @param admin*/public void register(Admin admin);
}
(2)adminServiceImpl实现类
@Service("adminService")
@Transactional
public class AdminServiceImpl implements AdminService {@Autowiredprivate AdminDao adminDao;@Overridepublic Admin login(Admin admin) {return adminDao.login(admin);}@Overridepublic void register(Admin admin) {adminDao.register(admin);}
}
3、功能测试(adminTest)
public class AdminTest {@Testpublic void login(){ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");AdminService adminService = (AdminService) context.getBean("adminService");Admin admin = new Admin(null,null, "王恒杰", "123456",true);Admin login = adminService.login(admin);System.out.println(login);}@Testpublic void register(){ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");AdminService adminService = (AdminService) context.getBean("adminService");Admin admin = new Admin(null, "风犬少年","邓正武", "234567",true);adminService.register(admin);}
}
4、Controller层
@Controller("adminController")
@RequestMapping("admin")
public class AdminController {/*** 将adminService到AdminController中*/@Autowiredprivate AdminService adminService;/*** 登录* @param admin* @return*/@RequestMapping("login")public String login(Admin admin,HttpServletRequest request){String password = MD5Utils.md5(admin.getPassword());admin.setPassword(password);Admin admin1 = adminService.login(admin);System.out.println(admin1);if(admin1!=null){request.getSession().setAttribute("admin",admin1);return "redirect:/emp/show";}return "redirect:/login.jsp";}/*** 注册* @param admin*/@RequestMapping("register")public String register(Admin admin){String password = MD5Utils.md5(admin.getPassword());admin.setPassword(password);adminService.register(admin);return "redirect:/login.jsp";}/*** 注销登录* @return*/@RequestMapping("destroy")public String destroy(HttpServletRequest request){request.getSession().invalidate();return "redirect:/login.jsp";}}
三、员工增删改查功能模块的开发

添加员工示意图
修改员工示意图
1、dao层(empDao.java)
public interface EmpDao {/*** 添加员工** @param emp*/public void insert(Emp emp);/*** 删除员工* @param id*/public void deleteById(Integer id);/*** 展示员工* @return*/public List<Emp> showEmp();/*** 修改员工* @param emp*/public void updateEmp(Emp emp);/*** 数据回显* @param id* @return*/public Emp selectEmpById(Integer id);
}
2、Service层
(1)empService接口层
public interface EmpService {/*** 添加员工** @param emp*/public void insert(Emp emp);/*** 删除员工* @param id*/public void deleteById(Integer id);/*** 展示员工* @return*/public List<Emp> showEmp();/*** 修改员工* @param emp*/public void updateEmp(Emp emp);/*** 数据回显* @param id* @return*/public Emp selectEmpById(Integer id);
}
(2)empServiceImpl实现类
@Service("empService")
/*** 控制事务*/
@Transactional
public class EmpServiceImpl implements EmpService {/*** 将empDao注入进@Service组件中*/@Autowiredprivate EmpDao empDao;public void setEmpDao(EmpDao empDao) {this.empDao = empDao;}@Overridepublic void insert(Emp emp) {empDao.insert(emp);}@Overridepublic void deleteById(Integer id) {empDao.deleteById(id);}@Override@Transactional(propagation = Propagation.SUPPORTS)public List<Emp> showEmp() {return empDao.showEmp();}@Overridepublic void updateEmp(Emp emp) {empDao.updateEmp(emp);}@Override@Transactional(propagation = Propagation.SUPPORTS)public Emp selectEmpById(Integer id) {return empDao.selectEmpById(id);}
}
3、功能测试(EmpTest)
public class EmpTest {/*** 添加员工*/@Testpublic void insert(){ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");EmpService empService = (EmpService) context.getBean("empService");Emp emp = new Emp(null,"邓正武",2000d,22);empService.insert(emp);}/*** 删除员工*/@Testpublic void deleteById(){ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");EmpService empService = (EmpService) context.getBean("empService");empService.deleteById(4);}/*** 展示员工* @return*/@Testpublic void showEmp(){ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");EmpService empService = (EmpService) context.getBean("empService");List<Emp> emps = empService.showEmp();for (Emp emp : emps) {System.out.println(emp);}}/*** 修改员工*/@Testpublic void updateEmp(){ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");EmpService empService = (EmpService) context.getBean("empService");Emp emp = new Emp(3,"邓正武",38000d,23);empService.updateEmp(emp);}/*** 数据回显* @return*/@Testpublic void selectEmpById(){ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");EmpService empService = (EmpService) context.getBean("empService");Emp emp = empService.selectEmpById(1);System.out.println(emp);}
}
4、Controller层
@Controller("emoController")
@RequestMapping("emp")
public class EmpController {/*** 注入empService在EmpController中*/@Autowiredprivate EmpService empService;/*** 添加员工** @param emp*/@RequestMapping("insert")public String insert(Emp emp){empService.insert(emp);return "redirect:/emp/show";}/*** 删除员工* @param emp*/@RequestMapping("delete")public String deleteById(Emp emp){empService.deleteById(emp.getId());return "redirect:/emp/show";}/*** 展示员工* @return*/@RequestMapping("show")public String showEmp(Model model){//调用业务方法List<Emp> emps = empService.showEmp();//作用域model.addAttribute("emps",emps);return "emplist";}/*** 修改员工* @param emp*/@RequestMapping("update")public String updateEmp(Emp emp){empService.updateEmp(emp);return "redirect:/emp/show";}/*** 数据回显* @param id* @return*/@RequestMapping("select")public String selectEmpById(Integer id,Model model){Emp emp = empService.selectEmpById(id);model.addAttribute("emp",emp);return "updateEmp";}
