SSH整合方案二(不带hibernate.cfg.xml)-白红宇

整体结构:

1.引入相关jar包

2.编写实体类和映射文件

package cn.zqr.domain;public class Customer {        private Long cust_id;    private String cust_name;    private Long cust_user_id;    private Long cust_create_id;    private String cust_source;    private String cust_industry;    private String cust_level;    private String cust_linkman;    private String cust_phone;    private String cust_mobile;        public Long getCust_id() {        return cust_id;    }    public void setCust_id(Long cust_id) {        this.cust_id = cust_id;    }    public String getCust_name() {        return cust_name;    }    public void setCust_name(String cust_name) {        this.cust_name = cust_name;    }    public Long getCust_user_id() {        return cust_user_id;    }    public void setCust_user_id(Long cust_user_id) {        this.cust_user_id = cust_user_id;    }    public Long getCust_create_id() {        return cust_create_id;    }    public void setCust_create_id(Long cust_create_id) {        this.cust_create_id = cust_create_id;    }    public String getCust_source() {        return cust_source;    }    public void setCust_source(String cust_source) {        this.cust_source = cust_source;    }    public String getCust_industry() {        return cust_industry;    }    public void setCust_industry(String cust_industry) {        this.cust_industry = cust_industry;    }    public String getCust_level() {        return cust_level;    }    public void setCust_level(String cust_level) {        this.cust_level = cust_level;    }    public String getCust_linkman() {        return cust_linkman;    }    public void setCust_linkman(String cust_linkman) {        this.cust_linkman = cust_linkman;    }    public String getCust_phone() {        return cust_phone;    }    public void setCust_phone(String cust_phone) {        this.cust_phone = cust_phone;    }    public String getCust_mobile() {        return cust_mobile;    }    public void setCust_mobile(String cust_mobile) {        this.cust_mobile = cust_mobile;    }    @Override    public String toString() {        return "Customer [cust_id=" + cust_id + ", cust_name=" + cust_name + ", cust_user_id=" + cust_user_id                + ", cust_create_id=" + cust_create_id + ", cust_source=" + cust_source + ", cust_industry="                + cust_industry + ", cust_level=" + cust_level + ", cust_linkman=" + cust_linkman + ", cust_phone="                + cust_phone + ", cust_mobile=" + cust_mobile + "]";    }    }

Customer 实体类

实体类映射文件

3.配置struts核心过滤器,和Spring文件加载的监听器


      
          
           
               
        
         org.springframework.web.context.ContextLoaderListener
            
           
               
        
         contextConfigLocation
                
        
         classpath:applicationContext.xml
            
           
           
               
        
         struts
                
        
         org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
            
           
               
        
         struts
                
        
         /*

struts核心过滤器的配置和Spring文件加载监听器

4.编写Action并配置,采用模型驱动的方式对表单进行封装,采用Spring注入的方式获取serice实例,并配置Action

/** * 客户的控制层 */public class CustomerAction extends ActionSupport implements ModelDriven{    private CustomerService customerService;    public void setCustomerService(CustomerService customerService) {        this.customerService = customerService;    }    //必须手动new    private Customer customer=new Customer();    //模型和属性驱动    /**     * 保存客户     * @return     */    public String add(){        customerService.save(customer);        return NONE;    }    @Override    public Object getModel() {        return customer;    }}

Action

使用Spring管理Action

Spring配置文件中配置Action

在struts中引入Action

struts.xml中引入Action

5.配置service

service层代码:

/** * 客户业务层 */@Transactionalpublic class CustomerServiceImpl implements CustomerService {    private CustomerDao customerDao;    public void setCustomerDao(CustomerDao customerDao) {        this.customerDao = customerDao;    }    /**     * 保存客户信息     * @param customer     */    @Override    public void save(Customer customer) {        customerDao.add(customer);    }}

Service层代码

service需要开事务,在Spring中配置事务,开启事务需要使用session,所以首先配置SessionFactory,创建session工厂需要数据源,所以需要优先配置数据源

配置数据源C3P0


              
               
                   
                        
         
          org.hibernate.dialect.MySQLDialect
                         
         
          true
                         
         
          true
                         
         
          update
                     
                
               
                   
                        
         
          Customer.hbm.xml

配置SessionFactory以及hibernate相关属性

最后配置事务并开启

配置事务并开启

6.编写dao层,dao层需要使用Hibernate模板(HibernateTemplate),为了简化开发,可以直接继承HibernateDaoSupport,然后向其注入sessionFactory

/** * 客户dao层 */public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {    /**     * 保存客户     */    @Override    public void add(Customer customer) {        System.out.println("持久层Customer customer"+customer);        this.getHibernateTemplate().save(customer);    }}

dao层代码
