struts2、hibernate、spring所需jar包

struts-core-2.x.x.jar  ----struts核心包
xwork-core-2.x.x.jar   -----身体ruts在其撒很难过构建
ognl-2.6.x.jar     ----对象导航语言
freemarker-2.3.x.jar   ------struts2的ui标签的模板使用
commons-fileupload-1.2.x.jar    ----文件上传组件 2.1.6版本后需加入此文件
struts-spring-plugin-2.x.x.jar   ---用于struts2继承spring的插件

1.先整合spring和hibernate
  *将spring和hibernate的jar包放入lib下；
  *创建spring的beans.xml配置文件
 

<?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:context="http://www.springframework.org/schema/context"

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

   *配置hibernate的model.hbm.xml和创建model类
   *创建service
     service接口：
     

public interface EmployeeService {
	public boolean save(Employee employee);
	public boolean update(Employee employee);
	public Employee find(String username);
	public boolean delete(String... username);//表示可变参数
	public List<Employee> findAll();
}

     service实现类：
    

import java.util.List;

import javax.annotation.Resource;

import org.apache.log4j.Logger;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.yss.bean.Employee;
import com.yss.service.EmployeeService;

/**
 * @author qing 默认bean名称 employeeServiceBean
 *@Service @Transactional 注入service和开启事务
 */
@Service
@Transactional
public class EmployeeServiceBean implements EmployeeService {
	private static Logger logger = Logger.getLogger(Employee.class);
	/**
	 * 注入sessionFactory
	 */
	@Resource SessionFactory factory;

	public boolean delete(String... usernames) {
		try {
			for (String username : usernames) {
				factory.getCurrentSession().delete(
						factory.getCurrentSession().load(Employee.class,
								username));
			}
		} catch (Exception e) {
			logger.error(e.getMessage());
			return false;
		}
		return true;
	}

	/*
	 * (non-Javadoc)
	 * 
	 * @see com.yss.service.EmployeeService#find(com.yss.bean.Employee)
	 * 此标注表示不需要事务处理
	 */
	@Transactional(propagation = Propagation.NOT_SUPPORTED)
	public Employee find(String username) {
		return (Employee) factory.getCurrentSession().get(Employee.class,
				username);
	}

	@SuppressWarnings("unchecked")
	@Transactional(propagation = Propagation.NOT_SUPPORTED)
	public List<Employee> findAll() {
		return factory.getCurrentSession().createQuery("from Employee emp")
				.list();
	}

	public boolean save(Employee employee) {
		try {
			factory.getCurrentSession().persist(employee);// .save(employee);//
															// 获取已经开好的Session
		} catch (Exception e) {
			logger.error(e.getMessage());
			return false;
		}
		return true;
	}

	public boolean update(Employee employee) {
		try {
			factory.getCurrentSession().merge(employee);// 类似于saveOrUpdate()方法
		} catch (Exception e) {
			logger.error(e.getMessage());
			return false;
		}
		return true;
	}

}

     *新建测试类
      

public class EmployeeTest {
	private static EmployeeService employeeService;

	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		try {
			ApplicationContext context = new ClassPathXmlApplicationContext(
					"beans.xml");
			employeeService = (EmployeeService) context
					.getBean("employeeServiceBean");
		} catch (Exception e) {
			System.out.println(e.getMessage());
		}
	}

	@Test
	public void createTable() {
		//new ClassPathXmlApplicationContext("beans.xml");
	};
	
	@Test
	public void save() {
		boolean result=employeeService.save(new Employee("long","long"));
		if (result) {
			System.out.println("保存成功。。。。。");
		}else{
			System.out.println("保存出错....");
		}
	};

	@Test
	public void delete() {
		boolean result=employeeService.delete("long");
		if (result) {
			System.out.println("删除成功。。。。。");
		}else{
			System.out.println("删除出错....");
		}
	};

	@Test
	public void update() {
		boolean result=employeeService.update((new Employee("qing","long")));
		if (result) {
			System.out.println("更新成功。。。。。");
		}else{
			System.out.println("更新出错....");
		}
	};

	@Test
	public void findAll() {
		List<Employee> elist=employeeService.findAll();
		Iterator itor=elist.iterator();
		while(itor.hasNext()){
			Employee emp=(Employee)itor.next();
			System.out.println(emp.getPassword());
		}
	};
	
	@Test
	public void find(){
		Employee employee=employeeService.find("qing");
		System.out.println(employee.getPassword());
	}
}

      *ok  没问题spring和hibernate整合完毕
      
       *再将struts2所需包加入lib中
       *创建struts.xml配置文件
      

<?xml version="1.0" encoding="UTF-8" ?>

         *在web.xml中加入
          

<?xml version="1.0" encoding="UTF-8"?>

      *创建相关jsp和action
      

@Controller  @Scope("prototype")
public class EmployeeManagerAction extends ActionSupport {
	@Resource EmployeeService employeeService;
	private Employee employee;
		
	public String addUI(){
		//System.out.println("user come");
		return SUCCESS;
	}
	
	public String add(){
		//System.out.println("--------------");
		boolean result=employeeService.save(employee);
		//ActionContext.getContext().put("genders", Gender.values());
		if(result){
			ActionContext.getContext().put("message", "保存成功!");
		}else{
			ActionContext.getContext().put("message", "保存失败!");
		}
		return "message";
	}

	public Employee getEmployee() {
		return employee;
	}

	public void setEmployee(Employee employee) {
		this.employee = employee;
	}
}
