Springboot：员工管理之环境准备（十（1））

1：静态资源

下载静态资源：https://files.cnblogs.com/files/applesnt/ztzy.zip

项目下载：https://files.cnblogs.com/files/applesnt/hellospringboot.zip

把css、js、img文件夹放在static目录下

把index.html、list.html、dashboard.html、404.html放在templates目录下

2：pom文件初始配置

            </plugin>

        </plugins>

    </build>

</project>

3：application.yml文件初始配置

server:

  port: 80 #访问端口

spring:

  thymeleaf:

    cache: false #开发时关闭缓存,不然没法看到实时页面

    prefix: classpath:/templates/ #文件存放路径

    suffix: .html  #文件后缀

    encoding: utf-8

    mode: HTML5

    servlet:

      content-type: text/html

4：构建java Bean

com\springboot\vo\Department.java #部门

使用@Data注解如要安装lombok插件

package com.springboot.vo;

import lombok.AllArgsConstructor;

import lombok.Data;

import lombok.NoArgsConstructor;

/*部门*/

@Data  //set get toString

@NoArgsConstructor //无参构造器

@AllArgsConstructor //有参构造器

public class Department {

	/*部门id*/

	private Integer id;

	/*部门名称*/

	private String departmentName;

}

com\springboot\vo\Employee.java #员工

package com.springboot.vo;

import lombok.AllArgsConstructor;

import lombok.Data;

import lombok.NoArgsConstructor;

import java.util.Date;

/*员工*/

@Data //set get toString

@AllArgsConstructor //有参构造器

@NoArgsConstructor  //无参构造器

public class Employee {

    /*员工id*/

	private Integer id;

	/*员工姓名*/

    private String lastName;

    /*邮箱*/

    private String email;

    /*性别 0：女  1：男*/

    private Integer gender;

    /*部门*/

    private Department department;

    /*生日*/

    private Date birth;

}

5：构建模拟数据

com\springboot\dao\DepartmentDao.java #构建部门数据

package com.springboot.dao;

import java.util.Collection;

import java.util.HashMap;

import java.util.Map;

import com.springboot.vo.Department;

import org.springframework.stereotype.Repository;

/*把部门dao注入spring容器*/

@Repository

public class DepartmentDao {

	private static Map<Integer, Department> departments = null;

	/*模拟部门表 数据库数据*/

	static{

		departments = new HashMap<Integer, Department>();

		departments.put(101, new Department(101, "D-AA"));

		departments.put(102, new Department(102, "D-BB"));

		departments.put(103, new Department(103, "D-CC"));

		departments.put(104, new Department(104, "D-DD"));

		departments.put(105, new Department(105, "D-EE"));

	}

	/*查询所有部门*/

	public Collection<Department> getDepartments(){

		return departments.values();

	}

	/*通过id查询部门*/

	public Department getDepartment(Integer id){

		return departments.get(id);

	}

}

com\springboot\dao\EmployeeDao.java #构建员工数据

package com.springboot.dao;

import java.util.Collection;

import java.util.Date;

import java.util.HashMap;

import java.util.Map;

import com.springboot.vo.Department;

import com.springboot.vo.Employee;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Repository;

@Repository

public class EmployeeDao {

	private static Map<Integer, Employee> employees = null;

	@Autowired

	private DepartmentDao departmentDao;

	/*模拟员工表 数据库中的数据*/

	static{

		employees = new HashMap<Integer, Employee>();

		employees.put(1001, new Employee(1001, "E-AA", "aa@163.com", 1, new Department(101, "D-AA"),new Date()));

		employees.put(1002, new Employee(1002, "E-BB", "bb@163.com", 1, new Department(102, "D-BB"),new Date()));

		employees.put(1003, new Employee(1003, "E-CC", "cc@163.com", 0, new Department(103, "D-CC"),new Date()));

		employees.put(1004, new Employee(1004, "E-DD", "dd@163.com", 0, new Department(104, "D-DD"),new Date()));

		employees.put(1005, new Employee(1005, "E-EE", "ee@163.com", 1, new Department(105, "D-EE"),new Date()));

	}

	private static Integer initId = 1006;

	/*添加员工*/

	public void save(Employee employee){

		if(employee.getId() == null){

			employee.setId(initId++);

		}

		employee.setDepartment(departmentDao.getDepartment(employee.getDepartment().getId()));

		employees.put(employee.getId(), employee);

	}

	/*查询所有员工*/

	public Collection<Employee> getAll(){

		return employees.values();

	}

	/*通过id查询员工*/

	public Employee get(Integer id){

		return employees.get(id);

	}

	/*删除员工*/

	public void delete(Integer id){

		employees.remove(id);

	}

}
