最新eclipse整合Struts2.3.29+Hibernate5.2.1+Spring4.3.1(三)Struts+Hibernate+spring篇

繼續,我又新建一個專案sshTest,把shDemo的程式碼都移進去(shDemo拿去幹別的事了得意

1.引入spring所需jar包

這裡不僅需要spring的jar包


還需要hibernate中兩個資料來源包


另外還有一個aspectjweaver.jar包,這個包在AOP配置的時候需要,現在spring的包裡面不提供了,要自己到網上下載。

2.修改web.xml檔案

在web.xml檔案中新增spring的監聽器和配置檔案位置以及hibernate的session過濾器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

		</init-param>  
	</filter>       
	<filter-mapping>  
		<filter-name>openSessionInViewFilter</filter-name>  
		<url-pattern>*.do,*.action</url-pattern>  
	</filter-mapping>
	
	<welcome-file-list>
		<welcome-file>/WEB-INF/jsp/login.jsp</welcome-file>
	</welcome-file-list>
</web-app>

3.在WEB-INF目錄下建立spring的配置檔案applicationContext.xml

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"

要重點注意以下幾點:

1.約束引入

2.依賴注入

3.面向切面配置


3.刪除Hibernate的配置檔案

它的工作已經交給spring去做了,所以Hibernate.cfg.xml已經不需要了,卸磨殺驢。

4.修改相應的類

由於applicationContext.xml註冊的物件必須要依賴注入(DI),以後物件的生成都由spring接管,所以以後在程式碼中就不應該出現new物件的情況,以下物件都要作出修改,要給依賴的物件無參的新增setter方法,有參的修改建構函式:

com.tzy.daoImpl.LoginDaoImpl.java

package com.tzy.daoImpl;

import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport;
import com.tzy.bean.User;
import com.tzy.dao.LoginDao;


public class LoginDaoImpl extends HibernateDaoSupport implements LoginDao {
	
	private User user;
	
	public void setUser(User user) {
		this.user = user;
	}

	@SuppressWarnings("unchecked")
	@Override
	public User getUser(String username) {

		@SuppressWarnings("resource")
		ApplicationContext context = new FileSystemXmlApplicationContext("E:/Data/workspace/sshTest/WebContent/WEB-INF/applicationContext.xml");
		user=(User) context.getBean("user");
		String hql = "from User"; 		
		List<User> list= (List<User>) this.getHibernateTemplate().find(hql);
		
		for(User user2 : list){
			if(username.equals(user2.getUsername())){
				user.setId(user2.getId());
				user.setUsername(user2.getUsername());
				user.setPassword(user2.getPassword());		
			}
		}
		return user;
	}
}
注:

1.ApplicationContext的生成有三種方法:FileSystemXmlApplicationContext、ClasspathXmlApplicationContext、WebXmlApplicationContext,都行,建議使用ClasspathXmlApplicationContext,我是為了省事;

2.getHibernateTemplate()這裡還是用的笨方法,不知道怎麼回事,這次用條件查詢還是會報錯,增刪改的方法都能操作成功,有空應該好好研究一下新版本API的改動了。


com.tzy.serviceImpl.LoginServiceImpl.java

package com.tzy.serviceImpl;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import com.tzy.bean.User;
import com.tzy.daoImpl.LoginDaoImpl;
import com.tzy.service.LoginService;

public class LoginServiceImpl implements LoginService {
	
	LoginDaoImpl loginDao;
	User user;
	
	public void setLoginDao(LoginDaoImpl loginDao) {
		this.loginDao = loginDao;
	}

	@Override
	public String checkUser(String username, String password) {

		@SuppressWarnings("resource")
		ApplicationContext context = new FileSystemXmlApplicationContext("E:/Data/workspace/sshTest/WebContent/WEB-INF/applicationContext.xml");
		loginDao = (LoginDaoImpl) context.getBean("loginDao");
		user = loginDao.getUser(username);
		if(user.getUsername()!=null){
			if(password.equals(user.getPassword())){
				return "success";
			}else{
				return "error";
			}
		}else{
			return "register";
		}
	}
}

com.tzy.action.LoginAction.java
package com.tzy.action;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import com.opensymphony.xwork2.ActionSupport;
import com.tzy.serviceImpl.LoginServiceImpl;

public class LoginAction extends ActionSupport{

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private String username;
	private String password;
	LoginServiceImpl loginService;
	
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	
	public void setLoginService(LoginServiceImpl loginService) {
		this.loginService = loginService;
	}
	@Override
	public String execute() throws Exception {

		@SuppressWarnings("resource")
		ApplicationContext context = new FileSystemXmlApplicationContext("E:/Data/workspace/sshTest/WebContent/WEB-INF/applicationContext.xml");
		loginService = (LoginServiceImpl) context.getBean("loginService");
		return loginService.checkUser(username, password);
	}
}

最終的檔案結構:



執行專案,操作資料庫均能成功。

最後,總結一句,如果遇到框架使用方面的問題,最好的解決辦法是去讀官方文件,官方給的東西肯定不會錯的,尤其是在使用老方法報錯的時候,先排除其他因素,然後按照官方給的例子先做出來,整個都調通了之後,回頭再優化並研究新改動的API,這一步我先偷懶了偷笑,回頭要是會用到再補上。
