SSH整合：Struts2+Spring+Hibernate

SSH整合：Struts2+Spring+Hibernate

一、导入Struts2和Spring和Hibernate的jar包
导入log4j.properties文件

二、编写web.xml文件


<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener- class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


<filter>
<filter-name>Struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

三、编写acclicationContext.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"> 


<context:property-placeholder location="classpath:jdbc.properties"/>

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="user" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">

<property name="dataSource" ref="dataSource"></property>

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
</props>
</property>

<property name="packagesToScan">
<list>
<value>cn.itcast.domain</value>
</list>
</property>
</bean>


<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>


<bean id="hibernateTemplate" class="org.springframework.orm.hibernate5.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>


<context:component-scan base-package="cn.itcast"></context:component-scan>


<tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

四、编写数据库连接jdbc.properties文件
jdbc.driver=com.mysql.jdbc.Driver(MySQL数据库)
jdbc.url=jdbc:mysql:///ssh262（数据库表）
jdbc.username=root（用户名）
jdbc.password=root（密码）

五、编写实体类
package cn.itcast.domain;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="cst_customer")
public class Customer {

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="cust_id")
private Long custId;

@Column(name="cust_name")
private String custName;

@Column(name="cust_source")
private String custSource;

@Column(name="cust_industry")
private String custIndustry;

@Column(name="cust_level")
private String custLevel;

@Column(name="cust_address")
private String custAddress;

@Column(name="cust_phone")
private String custPhone;
生成get、set方法

六、编写Action类
package cn.itcast.web.action;

import java.util.List;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

import cn.itcast.domain.Customer;
import cn.itcast.service.CustomerService;
@Controller("customerAction")
public class CustomerAction extends ActionSupport implements ModelDriven<Customer>{

private Customer customer = new Customer();
@Autowired
private CustomerService customerService;

@Override
public Customer getModel() {

return customer;
}
private List<Customer> list;
//查询客户列表
@Action(value="listCustomer",results={@Result(name="listCustomer",location="/jsp/customer/list.jsp")})
public String listCustomer(){
list = customerService.findAllCustomer(customer);
return "listCustomer";
}
public List<Customer> getList() {
return list;
}

public void setList(List<Customer> list) {
this.list = list;
}

public CustomerService getCustomerService() {
return customerService;
}

public void setCustomerService(CustomerService customerService) {
this.customerService = customerService;
}
}

七、编写业务类

public interface CustomerService {

List<Customer> findAllCustomer(Customer customer);
}

@Service("customerService")
public class CustomerServiceImpl implements CustomerService {

@Autowired
private CustomerDao customerDao;

//查找客户列表
@Override
public List<Customer> findAllCustomer(Customer customer) {

return customerDao.findAllCustomer(customer);
}
}

八、编写dao层

public interface CustomerDao {

List<Customer> findAllCustomer(Customer customer);
}

@Repository("customerDao")
public class CustomerDaoImpl implements CustomerDao{

@Autowired
private HibernateTemplate hibernateTemplate;
//查询客户列表
@Override
public List<Customer> findAllCustomer(Customer customer) {
return(List<Customer>) hibernateTemplate.find("from Customer");
}
}
