*自定义编码过滤器
web.xml 配置文件

global包下创建过滤器类

dao下entity创建实体类(toString,构造方法,get/set)

员工表类

//员工表类
public class Employee {
     
    private String sn;  //编号
    private String password;  //密码
    private String name;  //姓名
    private String department_sn;  //所属部门
    private String post;  //职务

dao下dao包创建Mapper接口

//员工表接口
public interface EmployeeMapper {
     
    //查全部
    public List<Employee> getAll();
    //根据sn查询
    public Employee getById(String sn);
    //增加员工
    public void add(Employee employee);
    //修改员工
    public void update(Employee employee);
    //删除员工(根据sn)
    public void delete(String sn);

}

同时dao下resources创建cn.com.dao同名包
创建Mapper.xml映射文件

<mapper namespace="cn.com.dao.EmployeeMapper">  
    

    
    <select id="getAll" resultType="Employee">
        SELECT * FROM `employee`;
    select>

    
    <select id="getById" parameterType="String" resultType="Employee">
        SELECT * FROM `employee` WHERE sn=#{sn};
    select>

    
    <insert id="add" parameterType="Employee">
        INSERT INTO `employee` (sn,password,name,department_sn,post) VALUES (#{sn},#{password},#{name},#{department_sn},#{post});
    insert>

    
    <update id="update" parameterType="Employee">
        UPDATE `employee` SET sn=#{sn},password=#{password},name=#{name},department_sn=#{department_sn},post=#{post} WHERE sn = #{sn};
    update>

    
    <delete id="delete" parameterType="String">
        DELETE FROM `employee` WHERE sn = #{sn};
    delete>

mapper>

biz(Service)下的biz包创建Service接口dao实现类

//员工接口实现类
@Service
public class EmployeeService implements EmployeeMapper {
     

    //注入dao层接口
    @Autowired
    private EmployeeMapper employeeMapper;

    //查全部
    public List<Employee> getAll() {
     
        return employeeMapper.getAll();
    }

    //根据sn查询
    public Employee getById(String sn) {
     
        return employeeMapper.getById(sn);
    }

    //添加
    public void add(Employee employee) {
     
        employeeMapper.add(employee);
    }

    //修改
    public void update(Employee employee) {
     
        employeeMapper.update(employee);
    }

    //删除
    public void delete(String sn) {
     
        employeeMapper.delete(sn);
    }
}

web下的test包创建Service层测试类

//Service层测试类
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-web.xml")
public class TestService {
     

    private Logger logger = Logger.getLogger(TestService.class);

    //注入部门表Service层接口实现类
    @Resource(name = "departmentService")
    private DepartmentService departmentService;

    //查询部门表
    @Test
    public void getAllDepartment(){
     
        List<Department> departments = departmentService.getAll();
        logger.info("部门信息查询如下:");
        for(Department d:departments){
     
            logger.info(d.toString());
        }
    }


    //注入员工表Service层接口实现类
    @Resource(name = "employeeService")
    private EmployeeService employeeService;

    //查询员工表
    @Test
    public void getAllEmployee(){
     
        List<Employee> employees = employeeService.getAll();
        logger.info("员工信息查询如下:");
        for(Employee e:employees){
     
            logger.info(e.toString());
        }
    }

    //根据sn查询员工
    @Test
    public void getById(){
     
        Employee employee = employeeService.getById("10004");
        logger.info("全部员工信息查询如下:");
            logger.info(employee.toString());
        }


    //添加员工信息
    //导入Spring容器实例
    @Resource(name = "employee1")
    private Employee employee1;

    @Resource(name = "employee2")
    private Employee employee2;

    @Test
    public void add(){
     
        employeeService.add(employee1);
        getAllDepartment();
        logger.info("添加一条员工信息成功!");
        getAllEmployee();
    }

    //修改员工信息

    @Test
    public void update(){
     
        Employee employee02 = new Employee("10005","123123","万茜","10003","员工");
        employee02.setSn("10005");
        employeeService.update(employee02);
        logger.info("修改员工信息成功!");
        getAllEmployee();
    }

    //删除一条员工信息
    @Test
    public void delete(){
     
        employeeService.delete("10005");
        logger.info("删除一条员工信息成功!");
        getAllEmployee();
    }
}

spring-web.xml 实例化对象用于添加数据(依赖实体类无参构造方法)

<bean id="employee1" class="cn.com.entity.Employee" p:sn="10005" p:password="123123" p:name="孙红雷" p:department_sn="10003" p:post="员工">bean>

<bean id="employee2" class="cn.com.entity.Employee" p:sn="10005" p:password="123123" p:name="张鲁一" p:department_sn="10003" p:post="员工">bean>

web下创建Controller控制类
进入添加修改页面方法,增删改查方法

项目控制类

//员工表控制类
@Controller
@RequestMapping("/employee")
public class EmployeeController {
     

    //注入Service层接口实现类
    @Resource(name = "employeeService")
    private EmployeeService employeeService;

    //注入Service层部门接口实现类
    @Resource(name = "departmentService")
    private DepartmentService departmentService;


/*    @RequestMapping(value = "/show")
    public String show() {
        System.out.println("进入Controller,show访问页面的映射,浏览器访问方法!");
        return "redirect:/employee/getAllModel";  //JSP页面
    }*/


    //1.查询员工信息
    //普通表单
    //使用ModelAndView的,JSP
    @RequestMapping(value = "/getAllModel")
    public ModelAndView getAllModel(){
     
        System.out.println("进入Controller,ModelAndView查询查询员工信息方法!");
        //查询集合,调用Service层方法
        List<Employee> employees = employeeService.getAll();
        ModelAndView modelAndView = new ModelAndView();
        //添加model数据
        modelAndView.addObject("employees",employees);
        //添加逻辑视图名,自动找页面
        modelAndView.setViewName("employee_list");
        System.out.println("封装完成! return modelAndView");
        return modelAndView;
        //进入JSP前端页面
    }


    //2.添加员工信息
    //SpringMVC的form表单
    //进入添加页面
    @RequestMapping(value = "/to_add")
    public String to_add(Map<String,Object> map){
     
        System.out.println("进入Controller,to_add访问页面的映射,浏览器访问方法!");
        map.put("employee",new Employee());
        //封装部门信息
        map.put("department",departmentService.getAll());
        //添加静态常量类的数据
        map.put("post", Contant.getPosts());
        return "employee_add";  //JSP页面
    }

    //添加员工
    @RequestMapping(value = "/insert")
    public String add(Employee employee) {
     
        System.out.println("进入Controller控制器,add方法,添加员工方法!");
        //执行添加工单
        employeeService.insert(employee);
        //返回到下面输出页面方法
        return "redirect:/employee/getAllModel";
    }


    //修改员工信息
    //SpringMVC的form表单
    //进入修改页面
    @RequestMapping(value = "/to_update")
    public String to_update(Map<String,Object> map, @RequestParam("sn") String sn){
     
        System.out.println("进入Controller,to_update访问页面的映射,浏览器访问方法!");
        map.put("employee",employeeService.getById(sn));
        //添加部门信息
        map.put("department",departmentService.getAll());
        //添加静态常量类的数据
        map.put("post", Contant.getPosts());
        return "employee_update";  //JSP页面
    }

    //修改员工
    @RequestMapping(value = "/update",params = "sn")
    public String update(Employee employee) {
     
        System.out.println("进入Controller控制器,update方法,编辑员工方法!");
        //执行添加工单
        employeeService.update(employee);
        //返回到下面输出页面方法
        return "redirect:/employee/getAllModel";
    }

    //删除员工信息
