Idea建立MAVEN项目整合SSH框架
1.首先建立maven-webapp项目，选择如下选项，
点击NEXT，填写项目信息，之后默认next，直至finish
项目建好后，项目结构如下:
可在main目录下手动建立项目所需目录，如下:
并右键点击Java文件夹，标记为:(Sources root 文件夹用来存放Java class文件，若不标记，在new文件时没有Java class选项)
并右键点击resources文件夹，标记为:（Resources Root用来存放资源文件，如XML，properties之类的）
标记后目录如下:
2.在POM.xml里添加依赖（不用maven时其实就是导入jar包），所需的各种依赖可去https://mvnrepository.com/找得。
pom.xml添加依赖后如图(这是我个人添加的依赖，也可以根据自己的需要去上面链接找寻依赖，在pom.xml添加依赖后，会自动从网上下载相关jar包存放在external libraries里，无需自己导入jar包)：

3.在resources文件夹下建好spring配置文件 applicationContext.xml
4.在resources文件夹下建好struts配置文件 struts.xml
5.在web.xml里配置spring和struts
Archetype Created Web Application
org.springframework.web.context.ContextLoaderListener
contextConfigLocation
classpath:applicationContext.xml
struts
org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
config
struts.xml
struts
/*
6.完善struts的配置
1)新建一个JSP，建立表单
<%@taglib uri="/struts-tags" prefix="s"%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
Title
保存信息
名称
描述
2）在Java文件夹下建立包结构以及相关类
Info类
public class Info {
private Integer pid;
private String name;
private String description;
public Integer getPid() {
return pid;
}
public void setPid(Integer pid) {
this.pid = pid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
@Override
public String toString() {
return "Info{" +
"name='" + name + '\'' +
", description='" + description + '\'' +
'}';
}
}
InfoAction类(这里利用modelDriven接口将JSP表单里的数据传递到Info类中)
public class InfoAction extends ActionSupport implements ModelDriven {
private Info info = new Info();
private InfoService infoService;
public void setInfoService(InfoService infoService) {
this.infoService = infoService;
}
@Override
public Info getModel() {
return info;
}
public void save(){
System.out.println("action.....");
infoService.save(info);
}
}
InfoService类
public class InfoService {
private InfoDao infoDao;
public void setInfoDao(InfoDao infoDao) {
this.infoDao = infoDao;
}
public void save(Info info){
System.out.println("service...");
infoDao.save(info);
}
}InfoDao类
public class InfoDao {
public void save(Info info){
System.out.println("dao.......");
System.out.println(info.toString());
}
}3)在struts.xml文件中配置数据交互
7.在applicationContext.xml文件中将spring与struts整合，即配置bean
8.配置好tomcat容器，运行JSP页面，报错：

解决措施，在web.xml中将
struts
org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
config
struts.xml
改为：
struts
org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
config
struts-default.xml,struts-plugin.xml,struts.xml
再次运行strutsDemo.jsp页面
点击保存：
后台输出：
至此spring和struts整合完成
9.利用mysql建立数据库sshdemo(暂不需要建表，hibernate映射文件会自动建表)
10.在resources文件夹下，建立jdbc.properties文件用来设置jdbc连接信息
11.在resources文件夹下，建立info.hbm.xml文件来设置类-表映射
info.hbm.xml：
12.在applicationContext.xml文件中将spring与hibernate整合
org.hibernate.dialect.MySQL5Dialect
true
true
update
info.hbm.xml
13.修改InfoDao类
public class InfoDao extends HibernateDaoSupport {
/*
在HibernateDaoSupport里有这个函数，在applicationContext.xml文件里对InfoDao注入了sessionFactory
注入之后就自动生成了hibernateTemplate，故下面save函数可以直接使用
* public final void setSessionFactory(SessionFactory sessionFactory) {
if (this.hibernateTemplate == null || sessionFactory != this.hibernateTemplate.getSessionFactory()) {
this.hibernateTemplate = this.createHibernateTemplate(sessionFactory);
}
}
* */
public void save(Info info){
this.getHibernateTemplate().save(info);
System.out.println("dao……");
}
}14.在InfoService类上加上@Transactional注解
@Transactional
public class InfoService {
private InfoDao infoDao;
public void setInfoDao(InfoDao infoDao) {
this.infoDao = infoDao;
}
public void save(Info info){
System.out.println("service...");
infoDao.save(info);
}
} 15.运行tomcat，打开jsp界面 ，填写表单
后台输出如下
数据库数据如下:
至此，SSH整合完成。
如有错误和不详细的地方欢迎指出，谢谢~
