Struts2.0+Springframework2.5+ibatis2.3完美整合用户登录及增删改查演示示例 连载中.(三)

　　好了，我们接着上篇继续我们的服务层及Struts的实现：
　　服务层这里我就不用做介绍了，这里的实现和以前Hibernate的例子基本类同，唯一不同的是使用了Spring2.5的标注方式实现类的注入。
　　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);
}

　　服务层实现：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层的实现也是比较简单了，与上述的区别都一样，在这里我就不太多说了。
　　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;
}
}

　　到现在为止，我们的底层的类已经全部实现了，下来我们看其配置文件：
　　struts.xml
　　

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<include file="struts-default.xml"/>
<package name="struts2" extends="struts-default">
<action name="logon" class="login">
<result name="success">/success.jsp</result>
<result name="input">/login.jsp</result>
</action>
<action name="save" class="login" method="save">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
<action name="update" class="login" method="update">
<result name="success">/success.jsp</result>
<result name="update">/update.jsp</result>
<result name="error">/error.jsp</result>
</action>
<action name="delete" class="login" method="delete">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
<action name="show" class="login" method="findAllUsers">
<result name="success">/list.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>

　　Struts.properties
　　

struts.locale=zh_CN
struts.i18n.encoding=UTF-8
struts.objectFactory=spring

　　接下来也是与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>

　　这个文件比较简单，只配置了bean的映射文件。

　　最后一个配置文件就是Spring的配置文件了，这个也是最关键的，与以前的配置是截然不同，因为在Spring2.5使用了标注方式注入，同时她了具有了自动的搜索bean的能力，所以配置就相当的简单，如果有不明白的地方，可以写到评论里，或者给我留言，这也是Spring2.5最难理解的地方了。
　　applicationContext.xml
　　

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>

</beans>
