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" %>


    


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~
