Spring集成Struts与Hibernate入门详解

前言

最近将spring,struts,hiberbate基础已经学习完成。想自己把这三个框架集成一下，然后再写一个后台管理网站练练手。spring的作用是依赖注入，而struts是显示层的东西，这两个框架集成后是什么样子。一边学习，一边记录。上车。

spring集成所需jar包

首先，spring集成struts，那么applicationcontext.xml和struts.xml,web.xml肯定是不能少的。前面两个是spring和struts的配置文件，后面一个是整个web的全局配置文件。在每个配置文件中应该怎么配置，怎么相互关联呢。其实就是将struts中指定的action 类为spring注入的类。

三大框架集成开发并不难，难的地方在于各个包的依赖要搞清楚，版本之间的差异也是一点。下面列出spring集成struts所依赖的包:

依赖包

此处所有依赖为struts2.0和spring3.0。版本有点老，我用最新版的始终集成不正确。等搞好了再升级版本。

number	package	platform	function
1	commons-fileupload-1.2.2.jar	common	文件上传功能
2	commons-io-2.0.1.jar	common
3	commons-lang-2.5.jar	common
4	commons-logging-1.1.1.jar	common	日志
5	freemarker-2.3.16.jar	struts	模版引擎
6	javassist-3.11.0.ga.jar	common	动态编程
7	ognl-3.0.1.jar	common	表达式语言，提供属性，方法调用
8	org.springframework.asm-3.1.1.release.jar	spring	spring独立的asm程序,spring2.5.6的时候需要asmjar 包3.0.6开始提供他自己独立的asmjar。暂时我自己也不懂这事干嘛的。
9	org.springframework.beans-3.1.1.release.jar	spring	spring ioc实现

集成

model层

新建usermodel，如下:

package com.action;
import java.io.serializable;
import javax.persistence.column;
import javax.persistence.entity;
import javax.persistence.generatedvalue;
import javax.persistence.id;
@entity
@javax.persistence.table(name="user")
public class user implements serializable{
 private static final long serialversionuid = 1l;
 @id
 @generatedvalue
 @column(name="id")
 public int id;
 @column(name="name")
 public string name;
 @column(name="password")
 public string password;
 
 public int getid() {
 return id;
 }
 public void setid(int id) {
 this.id = id;
 }
 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;
 }
 @override
 public string tostring() {
 return "user [name=" + name + ", password=" + password + "]";
 }
}

dao层

新建dao接口:

package com.dao.impl;
import java.util.list;
import com.action.user;
import com.action.useraction;
public interface userdao {
 public void save(user action);
 
 public user getuser(int id);
 
 public void update(user action);
 
 public void delete(user useraction);
 
 public list<user> findbyname(string name);
}

实现dao接口

package com.dao.impl;
import java.util.list;
import org.hibernate.sessionfactory;
import org.springframework.orm.hibernate3.hibernatetemplate;
import com.action.user;
import com.action.useraction;
public class userdaoimpl implements userdao {
 
 private sessionfactory sessionfactory;
 private hibernatetemplate mhibernatetemplate;
 
 public sessionfactory getsessionfactory() {
 return sessionfactory;
 }
 public void setsessionfactory(sessionfactory sessionfactory) {
 this.sessionfactory = sessionfactory;
 }
 public hibernatetemplate gethbernatetemplate() {
 if (mhibernatetemplate==null) {
 mhibernatetemplate = new hibernatetemplate(sessionfactory);
 }
 return mhibernatetemplate;
 }
 
 public void save(user action) {
 // todo auto-generated method stub
 gethbernatetemplate().save(action);
 }
 public user getuser(int id) {
 // todo auto-generated method stub
 user useraction = gethbernatetemplate().get(user.class, new integer(id));
 return useraction;
 }
 public void update(user action) {
 // todo auto-generated method stub
 gethbernatetemplate().update(action);
 }
 public void delete(user useraction) {
 // todo auto-generated method stub
 gethbernatetemplate().delete(useraction);
 }
 @suppresswarnings("unchecked")
 public list<user> findbyname(string name) {
 // todo auto-generated method stub
 string querystring = "from user u where u.name like ?";
 return gethbernatetemplate().find(querystring);
 }
 
}

view层

显示以及action

/**
 * 
 */
package com.action;
import javax.servlet.http.httpservletresponse;
import org.apache.struts2.servletactioncontext;
import com.dao.impl.userdaoimpl;
import com.opensymphony.xwork2.actionsupport;
/**
 * @author kevin
 *
 */
public class useraction extends actionsupport {
 public string name;
 public string password;
 private userdaoimpl userdao;
 
 public string getname() {
 return name;
 }
 
 public void setuserdao(userdaoimpl userdao) {
 this.userdao = userdao;
 }
 
 public userdaoimpl getuserdao() {
 return userdao;
 }
 public void setname(string name) {
 this.name = name;
 }
 
 
 public string getpassword() {
 return password;
 }
 public void setpassword(string password) {
 this.password = password;
 }
 @override
 public string execute() throws exception {
 // 不能直接new 得从applicationcontext中获取
 httpservletresponse response = servletactioncontext.getresponse();
 response.setcontenttype("text/xml;charset=utf-8");
 user user = new user();
 user.name = name;
 user.password = password;
 userdao.save(user);
 response.getwriter().write(user.tostring());
 return "success";
 }
}

数据库

最后看起来，还是不难的嘛。其实userdao可以抽象出来，只需要单次注入，等以后再完善。
