Struts2.0+ibatis2.3整合實(shí)例實(shí)現(xiàn)服務(wù)層及Struts
服務(wù)層這里我就不用做介紹了，這里的實(shí)現(xiàn)和以前Hibernate的例子基本類同，唯一不同的是使用了Spring2.5的標(biāo)注方式實(shí)現(xiàn)類的注入。
公司主營業(yè)務(wù)：做網(wǎng)站、網(wǎng)站制作、移動(dòng)網(wǎng)站開發(fā)等業(yè)務(wù)。幫助企業(yè)客戶真正實(shí)現(xiàn)互聯(lián)網(wǎng)宣傳，提高企業(yè)的競爭能力。創(chuàng)新互聯(lián)公司是一支青春激揚(yáng)、勤奮敬業(yè)、活力青春激揚(yáng)、勤奮敬業(yè)、活力澎湃、和諧高效的團(tuán)隊(duì)。公司秉承以“開放、自由、嚴(yán)謹(jǐn)、自律”為核心的企業(yè)文化，感謝他們對我們的高要求，感謝他們從不同領(lǐng)域給我們帶來的挑戰(zhàn)，讓我們激情的團(tuán)隊(duì)有機(jī)會(huì)用頭腦與智慧不斷的給客戶帶來驚喜。創(chuàng)新互聯(lián)公司推出青山免費(fèi)做網(wǎng)站回饋大家。
Struts2.0+ibatis2.3整合實(shí)例之IUserService.java
- package org.login.service;
- import java.util.List;
- import org.login.vo.Users;
- public interface IUserService {
- List﹤Users﹥ getAllUser();
- Users getUserById(Integer id);
- boolean isLogin(Users user);
- boolean insertUser(Users user);
- boolean updateUser(Users user);
- boolean deleteUser(Integer id);
- }
- 服務(wù)層實(shí)現(xiàn)：UserService.java
- package org.login.service.Impl;
- import java.util.List;
- import org.login.dao.IUserDAO;
- import org.login.service.IUserService;
- import org.login.vo.Users;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.beans.factory.annotation.Qualifier;
- import org.springframework.stereotype.Service;
- @Service("userService")
- public class UserService implements IUserService {
- @Autowired(required=false)
- @Qualifier("userDAO")
- private IUserDAO userDAO = null;
- public IUserDAO getUserDAO() {
- return userDAO;
- }
- public void setUserDAO(IUserDAO userDAO) {
- this.userDAO = userDAO;
- }
- @Override
- public boolean deleteUser(Integer id) {
- return userDAO.deleteUser(id);
- }
- @Override
- public List﹤Users﹥ getAllUser() {
- return userDAO.getAllUser();
- }
- @Override
- public boolean insertUser(Users user) {
- return userDAO.insertUser(user);
- }
- @Override
- public boolean isLogin(Users user) {
- return userDAO.isLogin(user);
- }
- @Override
- public boolean updateUser(Users user) {
- return userDAO.updateUser(user);
- }
- @Override
- public Users getUserById(Integer id) {
- return userDAO.getUserById(id);
- }
- }
Struts層的實(shí)現(xiàn)也是比較簡單了，與上述的區(qū)別都一樣，在這里我就不太多說了。
Struts2.0+ibatis2.3整合實(shí)例之Login.java
- package org.login.actions;
- import java.util.List;
- import javax.servlet.http.HttpServletRequest;
- import org.apache.struts2.interceptor.ServletRequestAware;
- import org.login.service.IUserService;
- import org.login.vo.Users;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.beans.factory.annotation.Qualifier;
- import org.springframework.stereotype.Service;
- import com.opensymphony.xwork2.ActionSupport;
- @SuppressWarnings({"serial","unchecked"})
- @Service("login")
- public class Login extends ActionSupport implements ServletRequestAware {
- private static final String UPDATE = "update";
- private HttpServletRequest request = null;
- @Autowired(required = false)
- @Qualifier("userService")
- private IUserService userService = null;
- private String id = null;
- private String name = null;
- private String password = null;
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getPassword() {
- return password;
- }
- public void setPassword(String password) {
- this.password = password;
- }
- public String getId() {
- return id;
- }
- public void setId(String id) {
- this.id = id;
- }
- public IUserService getUserService() {
- return userService;
- }
- public void setUserService(IUserService userService) {
- this.userService = userService;
- }
- @Override
- public String execute() throws Exception {
- Users user = new Users();
- user.setUserName(name);
- user.setPassword(password);
- if (getUserService().isLogin(user)) {
- return SUCCESS;
- }
- return INPUT;
- }
- public String save() throws Exception {
- Users user = new Users();
- user.setUserName(name);
- user.setPassword(password);
- if (getUserService().insertUser(user)) {
- return SUCCESS;
- }
- return ERROR;
- }
- public String update() throws Exception {
- Users user = null;
- String action = request.getParameter("action");
- String id = request.getParameter("id");
- if ("loading".equals(action)) {
- user = new Users();
- user = getUserService().getUserById(Integer.valueOf(id));
- if (null != user) {
- request.setAttribute("user", user);
- }
- return UPDATE;
- } else {
- user = new Users();
- user.setUserName(name);
- user.setPassword(password);
- user.setId(Integer.valueOf(id));
- if (getUserService().updateUser(user)) {
- return SUCCESS;
- }
- }
- return ERROR;
- }
- public String delete() throws Exception {
- String id = request.getParameter("id");
- if (getUserService().deleteUser(Integer.valueOf(id))) {
- return SUCCESS;
- }
- return ERROR;
- }
- public String findAllUsers() throws Exception {
- List﹤Users﹥ list = getUserService().getAllUser();
- if (list.size() ﹥ 0) {
- request.setAttribute("list", list);
- return SUCCESS;
- }
- return ERROR;
- }
- @Override
- public void setServletRequest(HttpServletRequest request) {
- this.request = request;
- }
- }
到現(xiàn)在為止，我們的底層的類已經(jīng)全部實(shí)現(xiàn)了，下來我們看其配置文件：
Struts2.0+ibatis2.3整合實(shí)例之struts.xml

Struts2.0+ibatis2.3整合實(shí)例之Struts.properties
struts.locale=zh_CN
struts.i18n.encoding=UTF-8
struts.objectFactory=spring
接下來也是與之前例子不同的地方，就是ibatis的配置文件：
config.xml
- ﹤?xml version="1.0" encoding="UTF-8"?﹥
- ﹤!DOCTYPE sqlMapConfig
- PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
- "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"﹥
- ﹤sqlMapConfig﹥
- ﹤sqlMap resource="org/login/vo/Users.xml"/﹥
- ﹤/sqlMapConfig﹥
這個(gè)文件比較簡單，只配置了bean的映射文件。
***一個(gè)配置文件就是Spring的配置文件了，這個(gè)也是最關(guān)鍵的，與以前的配置是截然不同，因?yàn)樵赟pring2.5使用了標(biāo)注方式注入，同時(shí)她了具有了自動(dòng)的搜索bean的能力，所以配置就相當(dāng)?shù)暮唵?，如果有不明白的地方，可以寫到評論里，或者給我留言，這也是Spring2.5最難理解的地方了。
