整合S2SH框架
S2SH框架(Struts2,Spring,Hibernate)整合
Struts2、Hibernate和Spring。其中在Struts2部分主要为MVC设计思想,Struts2的处理流程及配置,Struts2常用控制器组件,以及Struts2常用标签库的使用。在Hibernate部分主要为O/R Mapping的设计理念,Hibernate对O/R Mapping的支持,Hibernate的配置及多种关系映射的实现,以及HQL查询数据。在Spring部分主要为IoC的原理,Spring对Bean的管理机制,Spring AOP编程,以及声明事务的配置和管理。
下面来配置一下SSH搭建环境:
首先配置Hibernate环境,参考我之前的博客:http://www.cnblogs.com/claricre/p/6509931.html
接下来就是要配置Struts环境,参考我的博客:http://www.cnblogs.com/claricre/p/6542757.html
然后是配置Spring,参考博客:http://www.cnblogs.com/claricre/p/6686231.html
整合流程就是上面三篇博客,下面贴出来整个配置环境:
NationAction.java:
package com.action; import com.opensymphony.xwork2.ActionSupport; public class NationAction extends ActionSupport { public String show(){ return SUCCESS; } }
Nation.java实体类:
package com.model; // Generated 2017-4-11 16:20:44 by Hibernate Tools 5.2.0.CR1 /** * Nation generated by hbm2java */ public class Nation implements java.io.Serializable { private String code; private String name; public Nation() { } public Nation(String code) { this.code = code; } public Nation(String code, String name) { this.code = code; this.name = name; } public String getCode() { return this.code; } public void setCode(String code) { this.code = code; } public String getName() { return this.name; } public void setName(String name) { this.name = name; } }
Nation.hbm.xml:
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <!-- Generated 2017-4-11 16:20:44 by Hibernate Tools 5.2.0.CR1 --> <hibernate-mapping> <class name="com.model.Nation" table="nation" catalog="mydb" optimistic-lock="version"> <id name="code" type="string"> <column name="Code" length="50" /> <generator class="assigned" /> </id> <property name="name" type="string"> <column name="Name" length="50" /> </property> </class> </hibernate-mapping>
以上两个文件是通过Hibernate配置直接根据数据库表生成。

在页面中直接跑http://localhost:8080/SSH_zhenghe/Nation_show即可调出show.jsp页面的内容来了。
