关于SSH框架的一些整合要点

关于ssh框架的一些整合要点。昨天做了ssh框架的整合，但是也是感觉生疏了许多，下面介绍一下ssh整合的具体过程和常见问题的注意事项！

1：首先做struts部分的测试，在src目录导入struts.xml文件,然后在web.xml中添加核心过滤器strutsprepareandexecutefilter

在项目中导入相应的struts，spring，hibernate的jar包

编写一个测试页面index.

 

<%@ page language="java" import="java.util.*" pageencoding="gb18030"%>
<%@taglib prefix="c" uri="https://java.sun.com/jsp/jstl/core" %>
<%@taglib prefix="s" uri="/struts-tags" %>
<%
string path = request.getcontextpath();
string basepath = request.getscheme()+"://"+request.getservername()+":"+request.getserverport()+path+"/";
%>

登录

welcome login page

用户名： 密 码： 

在地址栏中键入一下url，出现如下界面说明struts配置成功！

2：spring和hibernate的整合：

 

a:建立jdbc.properties文件

b: 在web-inf下创建spring-hibernate.xml文件

/web-inf/spring-hibernate.xml

 

                    
                         com.li.model
                    
             
             		
                		hibernate.dialect=org.hibernate.dialect.mysqldialect
            		
             		
             

上面标红的一行的配置文件一定要放好位置哦，如果放到web-inf下会报错的要注意！！

 

c:创建user实体类对应中的表tb_user

 

import javax.persistence.column;
import javax.persistence.entity;
import javax.persistence.generatedvalue;
import javax.persistence.generationtype;
import javax.persistence.id;
import javax.persistence.table;
@entity
@table(name="tb_user")
public class user {
	private int id;
	private string username;
	private string password;
	@id
	@generatedvalue(strategy=generationtype.identity)
	public int getid() {
		return id;
	}
	public void setid(int id) {
		this.id = id;
	}
	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;
	}
	
}

 

d:建立userdao类 利用hibernate实现对底层数据库的操作

import java.util.arraylist;
import java.util.iterator;
import java.util.list;


import javax.annotation.resource;


import org.hibernate.session;
import org.hibernate.sessionfactory;
import org.hibernate.transaction;

//数据库访问层
import com.li.model.user;
public class userdao {

private sessionfactory sf;
public sessionfactory getsf() {
return sf;
}

//使用spring的自动注入功能
@resource(name="sessionfactory")
public void setsf(sessionfactory sf) {
this.sf = sf;
}

//获取用户列表信息
public list getusers() {
// todo auto-generated method stub
//打开hibernate的session
list users = new arraylist();
session session = sf.opensession();
transaction tc = (transaction) session.begintransaction();
list list = session.createquery("from user").list();
for (iterator iterator = list.iterator(); iterator.hasnext();) {
user u = (user) iterator.next();
users.add(u);
}
try {
tc.commit();
} catch (exception e) {
e.printstacktrace();
}
session.close();
return users;
}


}

e:建立userservice

import javax.annotation.resource;


import org.springframework.stereotype.component;
import org.springframework.stereotype.service;


import com.li.dao.userdao;
import com.li.model.user;
public class userservice {
private userdao userdao;
public userdao getuserdao() {
return userdao;
}
@resource(name="userdao")
public void setuserdao(userdao userdao) {
this.userdao = userdao;
}


//获得用户列表
public list getusers(){
return userdao.getusers();
}



}
f:建立action,showuseraction

import java.util.list;


import javax.annotation.resource;


import org.springframework.stereotype.controller;


import com.li.model.user;
import com.li.service.userservice;
import com.opensymphony.xwork2.actionsupport;
public class showusersaction extends actionsupport{

//存储接收的user列表信息
private list users;

//用户服务业务类
private userservice userservice;
public void setusers(list users) {

this.users = users;
}
public list getusers(){
return users;
}

public userservice getuserservice() {
return userservice;
}
@resource(name="userservice")
public void setuserservice(userservice userservice) {
this.userservice = userservice;
}

//演示用
public string listusers(){
system.out.println("userservice is " + userservice);
this.users = userservice.getusers();
system.out.println("users is " + this.getusers());
if(this.getusers() != null){
return success;
}else{
return error;
}

}
}
g:在struts.xml做如下配置：

h:当然最重要的是struts2-spring-plugins.jar包的导入，没有导入它会出现user is not mapped等等的错误信息

i:在web.xml作如下配置：

好了大功告成ssh整合完毕！文章有不足和错误之处欢迎指正。
