、

写实体

bean

package

import izable;

import

public class Student extends Page {

private int id

private String username;

private String password;

private String phone;

private String email;

private String address

private Page page;

public void setPage(Page page) {

= page;

}

public int getId() {

return id;

}

public void setId(int id) {

}

public String getUsername() {

return username;

me = username;

}

public String getPassword() {

return password;

}

rd = password;

}

public String getPhone() {

return phone;

}

public void setPhone(String phone) {

= phone;

}

public String getEmail() {

return email;

}

public void setEmail(String email) {

= email;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

s = address;

}

}

package

import izable;

public class Users implements Serializable {

private String username ;

private String password

public String getUsername() {

return username;

}

public void setUsername(String username) {

me = username;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

rd = password;

}

}

package

import izable;

import

public class Page{

private int pagesize;//

单页记录

private int currentpage = 1;//

当前页面

private int countdate;//

总记录数

private int lastPage;//

上一页

private int nextPage;//

下一页

private int countPage;

public int getCurrentpage()

{

return currentpage;

}

public void setCurrentpage(int currentpage)

{

if(currentpage>getCountpage())

{

tpage = getCountpage();

}else {

if(currentpage < 1)

{

tpage = 1;

}

else

{

tpage = currentpage;

}

}

}

public int getPagesize() {

return pagesize;

}

public void setPagesize(int pagesize) {

ze = pagesize;

}

public int getCountdate()

{

return countdate;

}

public void setCountdate(int countdate)

{

ate = countdate;

}

//

由记录数设定有关的页面数。

public int getCountpage()

{

int i = ate / ze;

if((ate % ze)!=0)

{

i+=1;

}

return i;

}

public int getLastPage()

{

return rentpage()-1;

}

public int getNextPage()

{

return rentpage()+1;

}

//

给

ibatis

用数据

public int getCurrent()

{

return (tpage-1)*pagesize;

}

public int getNext() {

return tpage*pagesize;

}

public int getCountPage() {

return countPage;

}

public void setCountPage(int countPage) {

age = countPage;

}

public void setLastPage(int lastPage) {

ge = lastPage;

}

public void setNextPage(int nextPage) {

ge = nextPage;

}

}

、

< /p>

编写

dao

及其实现类

< br>

package

import

import t;

public interface StudentDao {

public boolean saveStu(Student student);

public boolean delStu(int id);

public boolean updateStu(Student student);

public List queryAll();

public Student queryById(int id);

public List dimStu(Student student);

public int getCountSize(Object obj);

}

package

import eption;

import

import tedList;

import Client;

import tDao;

import t;

public class StudentDaoImpl implements StudentDao {

private SqlMapClient sqlMapClient;

public void setSqlMapClient(SqlMapClient sqlMapClient) {

Client = sqlMapClient;

}

public boolean delStu(int id) {

try {

int i = (

if(i>0){

return true;

}else{

return false;

}

} catch (SQLException e) {

tackTrace();

return false;

}

}

public List queryAll() {

List list = null;

Student st = new Student();

try {

list = orList(

} catch (SQLException e) {

// TODO Auto-generated catch block

tackTrace();

}

return list;

}

public Student queryById(int id) {

Student student = null;

try {

student = (Student) orObject(

} catch (SQLException e) {

tackTrace();

}

return student;

}

public boolean saveStu(Student student) {

boolean b;

try {

(

b = true;

} catch (SQLException e) {

tackTrace();

b = false;

}

return b

}

public boolean updateStu(Student student) {

boolean b

try {

(

b = true;

} catch (Exception e) {

b = false;

}

return b;

}

public List dimStu(Student student) {

List list = null;

try {

list = orList(

} catch (SQLException e) {

tackTrace();

}

return list;

}

public int getCountSize(Object obj) {

int i = 0

try {

i = (Integer)orObject(

} catch (SQLException e) {

// TODO Auto- generated catch block

tackTrace();

}

return i

}

}

package

import ;

public interface UserDao {

public boolean isLogin(Users user);

}

package

import eption;

import

import Client;

import o;

import

public class UserDaoImpl implements UserDao {

private SqlMapClient sqlMapClient;

public void setSqlMapClient(SqlMapClient sqlMapClient) {

Client = sqlMapClient;

}

public boolean isLogin(Users user) {

try {

List list = orList(

if(()>0)

{

return true;

}

} catch (SQLException e) {

tackTrace();

}

return false;

}

}

、

编写服务层及其实现

package t. servcie;

import

import t;

public interface StudentDao {

public boolean saveStu(Student student);

public boolean delStu(int id);

public boolean updateStu(Student student);

public List queryAll();

public Student queryById(int id);

public List dimStu(Student student);

public int getCountSize(Object obj);

}

package

import ;

import tDao;

import t;

import tService;

public class StudentServiceImpl implements StudentService {

private StudentDao sdao;

public void setSdao(StudentDao sdao) {

= sdao;

}

public boolean delStu(int id) {

boolean b = (id);

if(b){

return true;

}else{

return false;

}

}

public List queryAll() {

List list = ll();

return list;

}

public Student queryById(int id) {

Student student = yId(id);

return student;

}

public boolean saveStu(Student student) {

boolean b = u(student);

if(b){

return true;

}else{

return false;

}

}

public boolean updateStu(Student student) {

boolean b = Stu(student);

if(b){

return true;

}else{

return false;

}

}

public List dimStu(Student student) {

List list = (student);

return list;

}

public int getCountSize(Object obj) {

return ntSize(obj);

}

}

package e;

import

public interface UserService {

public boolean isLogin(Users user);

}

package

import o;

import

import rvice;

public class UserServiceImpl implements UserService {

private UserDao udao;

public void setUdao(UserDao udao) {

= udao;

}

public boolean isLogin(Users user) {

boolean b = n(user);

if(b){

return true;

}else{

return false;

}

}

}

、

编写< /p>

Action

类

package

import Context;

import Support;

import

import tService;

import rvice;

public class UserAction extends ActionSupport {

private UserService us;

private Users user;

public Users getUser() {

return user;

}

public void setUser(Users user) {

= user;

}

public UserService getUs() {

return us;

}

public void setUs(UserService us) {

= us;

}

public String Login() throws Exception {

String username = rname();

String password = sword();

boolean b = n(user);

if(b){

return

}else{

if((

text().put(

请输入用户名和密码！

}else if((

text().put(

请输入用户名

!

}else if((

text().put(

请输入密码！

}else{

text().put(

请检查用 户名和密码！

}

return

}

}

}
