二、几大框架的配置文件

1、导入ehcache

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"updateCheck="false"><!--磁盘存储:将缓存中暂时不使用的对象,转移到硬盘,类似于Windows系统的虚拟内存--><!--path:指定在硬盘上存储对象的路径--><!--java.io.tmpdir 是默认的临时文件路径。 可以通过如下方式打印出具体的文件路径 System.out.println(System.getProperty("java.io.tmpdir"));--><diskStore path="java.io.tmpdir"/><!--defaultCache：默认的管理策略--><!--eternal：设定缓存的elements是否永远不过期。如果为true，则缓存的数据始终有效，如果为false那么还要根据timeToIdleSeconds，timeToLiveSeconds判断--><!--maxElementsInMemory：在内存中缓存的element的最大数目--><!--overflowToDisk：如果内存中数据超过内存限制，是否要缓存到磁盘上--><!--diskPersistent：是否在磁盘上持久化。指重启jvm后，数据是否有效。默认为false--><!--timeToIdleSeconds：对象空闲时间(单位：秒)，指对象在多长时间没有被访问就会失效。只对eternal为false的有效。默认值0，表示一直可以访问--><!--timeToLiveSeconds：对象存活时间(单位：秒)，指对象从创建到失效所需要的时间。只对eternal为false的有效。默认值0，表示一直可以访问--><!--memoryStoreEvictionPolicy：缓存的3 种清空策略--><!--FIFO：first in first out (先进先出)--><!--LFU：Less Frequently Used (最少使用).意思是一直以来最少被使用的。缓存的元素有一个hit 属性，hit 值最小的将会被清出缓存--><!--LRU：Least Recently Used(最近最少使用). (ehcache 默认值).缓存的元素有一个时间戳，当缓存容量满了，而又需要腾出地方来缓存新的元素的时候，那么现有缓存元素中时间戳离当前时间最远的元素将被清出缓存--><defaultCache eternal="false" maxElementsInMemory="1000" overflowToDisk="false" diskPersistent="false"timeToIdleSeconds="0" timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU"/><!--name： Cache的名称，必须是唯一的(ehcache会把这个cache放到HashMap里)-->
<!--     <cache name="stuCache" eternal="false" maxElementsInMemory="100" -->
<!--            overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0" -->
<!--            timeToLiveSeconds="300" memoryStoreEvictionPolicy="LRU"/> -->
</ehcache>

2、导入日志框架log4j2.xml

}

6、BaseAction

 

package com.lxy.base.web;import java.io.Serializable;import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;public class BaseAction implements ServletRequestAware, ServletResponseAware,Serializable{private static final long serialVersionUID = -7110462505161900879L;/*** 为了传值使用*/protected HttpServletResponse response;protected HttpServletRequest request;protected HttpSession session;protected ServletContext application;/*** 为了配置跳转页面所用*/protected final static String SUCCESS = "success";protected final static String FAIL = "fail";protected final static String LIST = "list";protected final static String ADD = "add";protected final static String EDIT = "edit";protected final static String DETAIL = "detail";/*** 具体传值字段    后端向jsp页面传值所用字段*/protected Object result;protected Object msg;protected int code;public Object getResult() {return result;}public Object getMsg() {return msg;}public int getCode() {return code;}@Overridepublic void setServletResponse(HttpServletResponse arg0) {this.response = arg0;}@Overridepublic void setServletRequest(HttpServletRequest arg0) {this.request = arg0;this.session = arg0.getSession();this.application = arg0.getServletContext();}}

三、测试

将表描述成实体类，配置相关的映射文件

Book

package com.lxy.book.entity;import com.lxy.base.entity.BaseEntity;public class Book extends BaseEntity{private Integer bid;private String bname;private Float price;public Integer getBid() {return bid;}public void setBid(Integer bid) {this.bid = bid;}public String getBname() {return bname;}public void setBname(String bname) {this.bname = bname;}public Float getPrice() {return price;}public void setPrice(Float price) {this.price = price;}@Overridepublic String toString() {return "Book [bid=" + bid + ", bname=" + bname + ", price=" + price + "]";}}

2、Book.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping><class table="t_mvc_book" name="com.lxy.book.entity.Book"><id name="bid" type="java.lang.Integer" column="bid"><generator class="increment"></generator></id><property name="bname" type="java.lang.String" column="bname"></property><property name="price" type="java.lang.Float" column="price"></property></class>
</hibernate-mapping>

3、bookDao

package com.lxy.book.dao;import java.util.List;import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.springframework.orm.hibernate5.HibernateCallback;import com.lxy.base.dao.BaseDao;
import com.lxy.book.entity.Book;/*** 注意：*     1、一定要继承BaseDao（是为了获取到hibernateTemplete）*     2、方法命名有讲究（一定要符合声明式事务所定义的规则）*         若是不遵循规则，那么数据是不会提交到数据库*     3、hibernateTemplete模板在执行查询的时候比较特殊* @author Administrator**/
public class BookDao extends BaseDao {public int add(Book book) {return (int) getHibernateTemplate().save(book);}public void edit(Book book) {getHibernateTemplate().update(book);}public void del(Book book) {getHibernateTemplate().delete(book);}public List<Book> list(){return (List<Book>) getHibernateTemplate().execute(new HibernateCallback<List<Book>>() {@Overridepublic List<Book> doInHibernate(Session session) throws HibernateException {return session.createQuery("from Book").list();}});}
}

4、BookBiz

package com.lxy.book.biz;import java.util.List;import com.lxy.book.entity.Book;public interface BookBiz {public void add(Book book) ;public List<Book> list() ;}BookBizImpl :package com.lxy.book.biz.Imp1;import java.util.List;import com.lv.book.biz.BookBiz;
import com.lv.book.dao.BookDao;
import com.lv.book.entity.Book;public class BookBizImpl implements BookBiz{private BookDao bookDao;public BookDao getBookDao() {return bookDao;}public void setBookDao(BookDao bookDao) {this.bookDao = bookDao;}@Overridepublic void add(Book book) {bookDao.add(book);}@Overridepublic List<Book> list() {return bookDao.list();}}

5、BookAction

package com.lxy.book.web;import java.util.List;import com.lxy.base.web.BaseAction;
import com.lxy.book.biz.BookBiz;
import com.lxy.book.entity.Book;public class BookAction extends BaseAction {private Book book;public Book getBook() {return book;}public void setBook(Book book) {this.book = book;}private static final long serialVersionUID = 1L;private BookBiz bookBiz;public BookBiz getBookBiz() {return bookBiz;}public void setBookBiz(BookBiz bookBiz) {this.bookBiz = bookBiz;}public String add() {
//        http://localhost:8080/test_SSH/sy/bookAction_add.action?book.bid=131418&&book.bname=zs&&book.price=1this.bookBiz.add(book);return "success";}public String list() {
//        http://localhost:8080/test_SSH/sy/bookAction_list.actionList<Book> list = this.bookBiz.list();for (Book b : list) {System.out.println(b);}return "success";}}

6、Struts-sy.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN""http://struts.apache.org/dtds/struts-2.5.dtd">
