IDEA搭建SSH2框架

  之前一直学习和使用的都是SSM框架,最近公司使用的webwork,跟SSH相似,今天试着搭建一把SSH。

话不多说,开干!

1、首先创建项目,选择jdk、spring+struts2+hibernate。填写项目名,之后一路狂点。

2、惯例开始配置服务器tomcat。

3、选择file-project structure,选中加载的jar包起名lib。

4、在modules中加入配置好的tomcat依赖包和lib包。

5、配置artifacts。点击+选择Web Application:Exploaded--from modules,之后对Available Elements进行put into。

6、在tomcat中配置deployment,选中artifact,配置application context为/ ,build之后ok。

7、到此环境初步配置已经完成了。需要我们手动创建如下常规目录。

     action目录进行访问处理;Dao目录进行数据交互,定义接口;DaoImpl实现具体执行方法;model层写实体类以及hbm.xml映射文件;service目录编写相关逻辑代码;还会有util等看具体需求。

7.1、其中model中的实体类与映射文件可以通过工具自动生成。前提需要配置databases,并且连接成功(这步省略)。

        在model中添加JPA,之后左下角会出现Persistence,点击后出现项目右键选择generate persistence mapping,选择by database schema,进入下一步。

7.2、选中数据库以及生成路径、所要操作的表以及勾选separate XML即可。

PS: 这里说一下我在构建完后,发现配置文件中需要spring-web.jar包,然后手动添加了一下。

至此  项目搭建已经初步成型了,下面附上最重要的配置信息以及简单测试代码。

hibernate.cfg.xml (此文件主要配置mapping resource和class路径,也可直接配置在applicationContext.xml中)





    
        
        
        com.mysql.jdbc.Driver

User实体:

package com.css.user.model;
import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import java.io.Serializable;
import java.util.Objects;
@Entity
public class User implements Serializable {
    private String id;
    private String name;
    private Integer age;
    private Integer tell;
    @Id
    @Column(name = "id", nullable = false, length = 255)
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    @Basic
    @Column(name = "name", nullable = true, length = 255)
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @Basic
    @Column(name = "age", nullable = true)
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    @Basic
    @Column(name = "tell", nullable = true)
    public Integer getTell() {
        return tell;
    }
    public void setTell(Integer tell) {
        this.tell = tell;
    }
    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        User user = (User) o;
        return Objects.equals(id, user.id) &&
                Objects.equals(name, user.name) &&
                Objects.equals(age, user.age) &&
                Objects.equals(tell, user.tell);
    }
    @Override
    public int hashCode() {
        return Objects.hash(id, name, age, tell);
    }
}

实体映射 User.hbm.xml:





    
        
            
        
        
            
        
        
            
        
        
            
        
    

核心Dao:baseDao:

package com.css.user.Dao;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
public class baseDao {
    private SessionFactory sessionFactory;
    private Session session;

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
    public Session getSession(){
        return sessionFactory.openSession();
    }

}

Dao接口:userListDao:

package com.css.user.Dao;
import java.util.List;
public interface userListDao {
    public  List findUserList();
}

Dao实现:userDaoImpl:

package com.css.user.DaoImpl;


import com.css.user.Dao.userListDao;
import com.css.user.model.User;
import com.opensymphony.xwork2.util.logging.Logger;
import com.opensymphony.xwork2.util.logging.LoggerFactory;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.query.Query;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import javax.annotation.Resource;
import java.util.List;
import com.css.user.Dao.baseDao;

    @Transactional
    @Repository("userListDao")
    public class userDaoImpl extends baseDao implements userListDao {
        @Override
        public List findUserList() {
            Session session=getSession();
            Transaction ts=session.beginTransaction();
            System.err.println("========in findUserList=====");
            Query query=session.createQuery("from User");
            System.err.println("==========query:"+query.toString()+"==========");
            List list=query.list();
            ts.commit();
            session.close();
            return list;
         }
    }

action访问控制:

      getUser(实现简单的框架验证):

package com.css.user.action;

import com.css.user.model.User;
import com.opensymphony.xwork2.ModelDriven;
import org.hibernate.SQLQuery;
import org.omg.PortableInterceptor.SUCCESSFUL;
import org.omg.PortableInterceptor.ServerRequestInfo;
/*import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;*/
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
import org.springframework.web.struts.ActionSupport;
import java.sql.SQLClientInfoException;
import java.util.List;

public class getUser extends HibernateDaoSupport implements ModelDriven {  //extends ActionSupport HibernateDaoSupport
    private User adminUser = new User();
    public User getAdminUser() {
        return adminUser;
    }
    public void setAdminUser(User adminUser) {
        this.adminUser = adminUser;
    }
    public String execute() throws Exception{
        System.err.println("=============================in method--getUser=======================");
        System.out.println("===============:"+adminUser.getName());
        System.out.println("===============:"+adminUser.getId());
        if(adminUser.getName().equals(adminUser.getId())){
            return "success";
        }else{
           return "error";
       }
    }
    @Override
    public User getModel() {
        return adminUser;
    }
}

      findUser (实现User表的数据查询):

package com.css.user.action;

import com.css.user.DaoImpl.userDaoImpl;
import com.css.user.model.User;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ModelDriven;


import org.hibernate.Hibernate;
import org.hibernate.SQLQuery;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.query.Query;
import org.springframework.context.ApplicationContext;
import org.springframework.orm.hibernate3.SessionFactoryUtils;
import org.springframework.orm.hibernate4.support.HibernateDaoSupport;
import org.springframework.orm.hibernate3.HibernateTemplate;
import com.css.user.DaoImpl.userDaoImpl;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import com.css.user.Dao.userDao;
public class findUser extends HibernateDaoSupport implements ModelDriven{  //extends ActionSupport HibernateDaoSupport
    private  userDaoImpl userDaoIm;
    //当添加有参构造方法时必须手动添加无参构造
    public findUser() {
    }
    public String findUser() throws Exception{
        System.err.println("=======hql========");
        List userList=(List) ActionContext.getContext().get("userList");
        userList = userDaoIm.findUserList();
        if(userList.size()!= 0){
            return "success";
        }else{
            return "error";
        }
    }
    @Override
    public Object getModel() {
        return null;
    }
    public userDaoImpl getUserDaoIm() {
        return userDaoIm;
    }
    public void setUserDaoIm(userDaoImpl userDaoIm) {
        this.userDaoIm = userDaoIm;
    }
}
