管理系统-------------SSH框架书写登录和显示用户

一、思路的穿插。

　　　　web.xml中的配置找到--->application.xml---->找到对应的Action---->找到struts.xml----->在去找action----->service的实现类---->dao的impl实现类。

二、SSH框架整合需要的jar

　　

　　　　

三、实现登录

　　（一）、创建实体

/*
 * 员工表
 * */
@Entity
@Table(name="sys_employee")
public class Employee {
    @Id
    @GeneratedValue
    private String  Sn;//员工编号
    private Integer Position_id;//岗位编号
    private Integer Department_id;//部门编号
    private String Name;//员工姓名
    private String Password;//密码
    private String Stuatus;//状态
    @ManyToOne(fetch=FetchType.LAZY)//和岗位表是多对一的关系
    @JoinColumn(name="Posiid")
    private Position position;

    @ManyToOne(fetch=FetchType.LAZY)
    private Department department;

　　//省get/set方法
    }

/*
 * 岗位表
 * */
@Entity
@Table(name="sys_position")
public class Position {
    @Id
    @GeneratedValue
    @Column(name="ID")
     private Integer Posiid;//岗位编号
    @Column(name="NAME_CN")
     private String Name_cn;//岗位名称（中文）
    @Column(name="NAME_EN")
     private String Name_en;//岗位名称（英文）

　　　　//省get/set方法
}

　　（二）1.创建dao

public interface LoginDao {
    //登录
    public Employee login(Employee emp) throws Exception;
}

　　　　2.dao.Impl

public class LoginDaoImpl implements LoginDao {
    private SessionFactory sessionFactory;//创建一个工厂对象
　　　　//登录
    public Employee login(Employee emp) throws Exception {
       // System.out.println("SessionFactory"+sessionFactory);
        //System.out.println("Session"+getSesion());
        String hql = "from Employee where Sn=? and Password=?";
        Employee emps=(Employee) getSesion().createQuery(hql).setString(0,emp.getSn()).setString(1, emp.getPassword()).uniqueResult();
        System.out.println(emps);
        return emps;
    }
    //创建一个工厂
    private Session getSesion() {
        return sessionFactory.getCurrentSession();

    }
    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

}

　　（三）1.创建service.dao

public interface LoginServiceDao {
    //登录
    public Employee login(Employee emp) throws Exception;
}

　　2.创建service.Impl

public class LoginServiceDaoImpl implements LoginServiceDao {

    //登录的daoimpl的对象
    private LoginDaoImpl li;

    @Transactional
    public Employee login(Employee emp) throws Exception {
        // TODO Auto-generated method stub
        System.out.println("实现类");
                return li.login(emp);
    }

    public LoginDaoImpl getLi() {
        return li;
    }

    public void setLi(LoginDaoImpl li) {
        this.li = li;
    }

}

　　（四）创建Action

public class LoginAction extends ActionSupport {
    private LoginServiceDao oaservice;
    private Employee emp;

    public String login() throws Exception {

        Employee employee = oaservice.login(emp);
        if (employee!=null) {

            ServletActionContext.getRequest().getSession().setAttribute("emp", employee);
            //ServletActionContext.getRequest().getSession().setAttribute("position",employee.getPosition().getName_cn());
            //ServletActionContext.getContext().getSession().put("position", employee);
            return SUCCESS;
        }else
        return INPUT;
    }

    public LoginServiceDao getOaservice() {
        return oaservice;
    }

    public void setOaservice(LoginServiceDao oaservice) {
        this.oaservice = oaservice;
    }

    public Employee getEmp() {
        return emp;
    }

    public void setEmp(Employee emp) {
        this.emp = emp;
    }

}

（五）配置文件

四、实现部门显示信息用（easyUI）

　　（一）创建dao

public interface IdepartmentDao {
//查看所有的部门
    public List<Department> getDepar();
    //根据分页查询出指定的部门信息
    public List<Department> getdeptBypage(int pageSize, int pageIndex)throws Exception;

    //查询所有记录
    public int getAllCount() throws Exception;

}

　　Impl实现类

public class DeparmentAction extends ActionSupport {
    private IdeparmentServiceDao serviceDao;

    private Department dept;
    private List<Department> deptlist;

    private Integer rows;//和datagrid控件绑定的记录条数
    private Integer page;//和datafrid控件绑定的页码数
    private int size;
    private String json;

    public String getList() throws Exception{
        System.out.println("AAAAAAAA");
        List<Department> list = serviceDao.getdeptBypage(rows, page);
        System.out.println(list+"bbb");
        setDeptlist(list);
        size=serviceDao.getAllCount();
        ServletActionContext.getResponse().setCharacterEncoding("utf-8");
        ServletActionContext.getResponse().setContentType("text/html;charset=UTF-8");

        System.out.println(getJson().getBytes("utf-8"));
        ServletActionContext.getResponse().getOutputStream().write(getJson().getBytes("utf-8"));
        return NONE;
    }

    @Override

    public String execute() throws Exception {

        /*System.out.println("action");
        System.out.println("serviceDao"+serviceDao);*/
        List<Department> depar = serviceDao.getDepar();
        for (Department item : depar) {
            System.out.println(item.getDaparid());
            System.out.println(item.getDaparidname());
        }

        if(depar!=null){
            return SUCCESS;
        }
        return INPUT;
    }
    public IdeparmentServiceDao getServiceDao() {
        return serviceDao;
    }
    public void setServiceDao(IdeparmentServiceDao serviceDao) {
        this.serviceDao = serviceDao;
    }
    public Department getDept() {
        return dept;
    }

    public void setDept(Department dept) {
        this.dept = dept;
    }

    public List<Department> getDeptlist() {
        return deptlist;
    }

    public void setDeptlist(List<Department> deptlist) {
        this.deptlist = deptlist;
    }

    public Integer getRows() {
        return rows;
    }

    public void setRows(Integer rows) {
        this.rows = rows;
    }

    public Integer getPage() {
        return page;
    }

    public void setPage(Integer page) {
        this.page = page;
    }

    public int getSize() {
        return size;
    }

    public void setSize(int size) {
        this.size = size;
    }

    public String getJson() {
        String json=null;
        try {
            json = "{\"total\":"+size+",\"rows\":"+JSONUtil.serialize(getDeptlist())+"}";
        } catch (JSONException e) {
            e.printStackTrace();
        }
        System.out.println("aaa"+json);
        return json;

    }

    public void setJson(String json) {
        this.json = json;
    }

　　（二）service.dao

public interface IdeparmentServiceDao {
    //查看所有的部门
    public List<Department> getDepar();
    //根据分页查询出指定的部门信息
        public List<Department> getdeptBypage(int pageSize, int pageIndex)throws Exception;

        //查询所有记录
        public int getAllCount() throws Exception;
}

　　　　Impl

public class DeparmentServiceDaoImpl implements IdeparmentServiceDao{
    private IdepartmentDaoImpl deparmentImpl;

    @Transactional
    public List<Department> getDepar() {
        System.out.println("DeparmentServiceDaoImpl");
        System.out.println("deparmentImpl"+deparmentImpl);
        return deparmentImpl.getDepar();
    }
    public List<Department> getdeptBypage(int pageSize, int pageIndex)
            throws Exception {

        return deparmentImpl.getdeptBypage(pageSize, pageIndex);
    }

    public IdepartmentDaoImpl getDeparmentImpl() {
        return deparmentImpl;
    }
    public void setDeparmentImpl(IdepartmentDaoImpl deparmentImpl) {
        this.deparmentImpl = deparmentImpl;
    }
    public int getAllCount() throws Exception {

        return deparmentImpl.getAllCount();
    }

}

public class DeparmentAction extends ActionSupport {
    private IdeparmentServiceDao serviceDao;

    private Department dept;
    private List<Department> deptlist;

    private Integer rows;//和datagrid控件绑定的记录条数
    private Integer page;//和datafrid控件绑定的页码数
    private int size;
    private String json;

    public String getList() throws Exception{
