实体类
public class Employee {
private Integer id;
private String lastName;
private String email;
//1 male, 0 female
private Integer gender;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Integer getGender() {
return gender;
}

this.gender = gender;
}
public Employee(Integer id, String lastName, String email, Integer
gender) {
super();
this.id = id;
this.lastName = lastName;
this.email = email;
this.gender = gender;
}
public Employee() {
}
}
dao模拟数据
import java.util.Collection;
import java.util.HashMap;
import java.util.Map;
import MaHangLian.bean.Employee;
import org.springframework.stereotype.Repository;
@Repository
public class EmployeeDao {
private static Map employees = null;
static {
employees = new HashMap();
employees.put(1001, new Employee(1001, "E-AA", "[email protected]", 1));
employees.put(1002, new Employee(1002, "E-BB", "[email protected]", 1));
employees.put(1003, new Employee(1003, "E-CC", "[email protected]", 0));
employees.put(1004, new Employee(1004, "E-DD", "[email protected]", 0));
employees.put(1005, new Employee(1005, "E-EE", "[email protected]", 1));
}
private static Integer initId = 1006;
public void save(Employee employee) {
if (employee.getId() == null) {
employee.setId(initId++);
}
employees.put(employee.getId(), employee);
}
public Collection getAll() {
return employees.values();
}
public Employee get(Integer id) {
return employees.get(id);
}
public void delete(Integer id) {
employees.remove(id);
}
}
2.功能清单
3.访问首页
3.1：配置view-controller
3.2创建页面
Title
首页
访问员工信息
4.查询所有员工数据
4.1控制器方法
@RequestMapping(value = "/employee", method = RequestMethod.GET)
public String getEmployeeList(Model model){
Collection employeeList = employeeDao.getAll();
model.addAttribute("employeeList", employeeList);
return "employee_list";
}
4.2创建employee_list.html
Employee Info
Employee Info
id
lastName
email
gender
options(add)
delete
update
5.删除
5.1创建处理delete请求方式的表单
5.2删除超链接绑定点击事件
引入vue.js
删除超链接
delete
通过vue处理点击事件
5.3控制器方法
@RequestMapping(value = "/employee/{id}", method = RequestMethod.DELETE)
public String deleteEmployee(@PathVariable("id") Integer id){
employeeDao.delete(id);
return "redirect:/employee";
}
6.跳转到添加数据页面
6.1配置view_controller
6.2创建employee_add.html
Add Employee
7.执行保存
7.1控制器方法
@RequestMapping(value = "/employee", method = RequestMethod.POST)
public String addEmployee(Employee employee){
employeeDao.save(employee);
return "redirect:/employee";
}8.跳转到更新数据页面
8.1修改超链接
update
8.2控制器方法
@RequestMapping(value = "/employee/{id}", method = RequestMethod.GET)
public String getEmployeeById(@PathVariable("id") Integer id, Model model){
Employee employee = employeeDao.get(id);
model.addAttribute("employee", employee);
return "employee_update";
}
8.3创建employee_update.html
Update Employee
9.执行更新
9.1控制器方法
@RequestMapping(value = "/employee", method = RequestMethod.PUT)
public String updateEmployee(Employee employee){
employeeDao.save(employee);
return "redirect:/employee";
}

使用ServletAPI向request域对象共享数据
使用ModelAndView向request域对象共享数据
使用Model向request域对象共享数据
4、使用map向request域对象共享数据
5、使用ModelMap向request域对象共享数据
7、通过ServletAPI向向session域共享数据
8、向application域共享数据
