-【优秀文档】ssh的一点想法

1、是我为新项li专门搭建的基于全注解方式的ssh基础框架，虽然是老掉牙的的东西, 自我感觉很良好，好东西不敢独享，晒晒等拍砖。概述：基于 struts2.23 + spring2.5.6 + hibernate3.6.4 + hibernate-generic-dao1.0 （除t spring,我整合的都是最新的ga包,hibernate-generic-dao是google项目 库屮一个开源的basedao,我灰常喜欢，因为我找不到更好更适合我的） 项目代码是基于eclipse3.6创建的，很简单，大家直接导入则可运行。1 包结构，源码，测试用例，配置文件一 h 了然。每个功能模块都在mod

2、ules包下 做开发，配置文件统一在resource管理（基实也没多少配置文件，都用注解嘛）。針 org厶 chinasb卩 framework ® core厶铮base> 凸 action> 鋅 dao> 务 search0 & db厶凸 modules厶 0 demo> 凸 action> 凸 dao> 凸 model> 凸 service0 凸 util& resources> 凸 content> 凸 hibernatet> & iog4j> & spring> 凸 str

3、uts凸 test厶 d org厶凸 chinasb 0 framework> 凸 core> 凸 modules2无论阅读哪个web项冃代码，我都是先从web.xml开始，项冃有什么东西一淸二 楚。我这里将iog4j监听放在第一，我想他应该能够从系统启动开启就能记录我的所有日 志（求认证）。第二个监听是proxool数据库连接池，听说很高效，所以果断引入（引入步骤搞得复杂吧，我还重写了监听。一切为了稳定，也好扩展我某ii喜欢加 入动态切换数据源做准备。呵呵）。opensessionlnview,我想如果你不喜欢可以 摘掉，反正我很喜欢。struts2指定了自定义的struts.x

4、ml文件位置，指定扫描注解 的action路径。最后是proxool的叮视化图形监控，很棒。<?xml version二"1. 0 encoding二utf-8"?><webapp xmlns:xsi二http:/www. w3. org/2001/xmlschema-instance，z xmlns=/zhttp: /java. sun. com/xml/ns/javaee，zxml ns: web=/zht tp: / java. sun. com/xml/ns/ javaee/web-app_2_5. xsdxsi: schemcilocation二

41、rg. chinasb. framework, modules"/</struts>好了，下面我简单讲一下开发流程。在modules下建立模块,和相应的包(action,dao,model,service,util),比如我上面包 结构的demo模块。demo.java, model类，映射数据库屮的表，每个model 张表，为了适应basedao, 每个model还对应每个dao (不要觉得这是麻烦的)。jpa的注解，你们懂的，不 解释。package org. chinasb. framework, modules, demo, model;import java.

42、io. serializable;import java. util. datc;import javax.persistence. entity;import javax. persistence. generatedvalue; import javax. persistenee. generationtype;import javax. persistence. id;import org.hibernate, annotations. cache;import org. hibernate, armotations. cacheconcurrencystrategy;entity飢ac

43、he(usage = cacheconcurrencystrategy. nonstr1ct read write) public class demo implements serializable private static final long serialversionutd = il;id©generatedvalue (strategy = generationtype. auto) private int id;private string title;private string content;privatc date publishdate;public int

44、 getld() return id;public void setld(int id) this, id 二 id;public string gettitle()return title;public void settitle(string title) this.title 二 title;public string getcontent() :retufn content;public void setcontent (string content) this, content = content;public date gctpublishdatco return publishd

45、ate;public void setpublishdate(date publishdate) this.publishdatc 二 publishdatc;demodao,接口类。我想在多数程序员的项h里做的绝大多数事情都是相关数据库 的curd操作，所以基础框架里整合一个强大的basedao是必须的，而我选择了 开源的genericdao (觉得不适合你的可以替掉)。直接继承genericdao接口，指 定操作的model, -4主键的类型。package org. chinasb. framework, modules. demo, dao;import org. chinasb. f

46、ramework, core. base. dao. hibernate. genericdao; import org. chinasb. framework, modules, demo, model. demo;public interface demodao extends genericdao<demo, tnteger> demodaoimpi,呵，这样写我觉得不麻烦，不多说。repository注解交给spring 管理。package org. chinasb. framework, modules, demo. dao. impl;import org. chin

47、asb. framework, core. base. dao. basedao; import org.chinasb. framework, modules, demo. dao. demodao;import org. chinasb. framework, modules, demo, model. demo; import org. springframework. stereotype. repository;rcpositorypublic class demodaolmpl extends basedao<demo, lnteger> implements demo

48、dao basedao,主要是注入 sessionfactory 给 hibernate-genericdao。 package org.chinasb. framework, core. base, dao;import java. io.serializable;import org. chinasb. framework, core. base. dao. hibernate. genericdaotmpl; import org.hibernate. scssionfactory;import org. springframework. beans, factory, annotati

49、on. autowired;public class basedacxt, id extends serializable> extends genericdaotmpl<t, td> autowired©overridepublic void setsessionfactory(sessionfactory sessionfactory) super, setsessionfactory(sessionfactory);ijdemoservice,接下来就要定义一些相关数据库操作的业务接口给上层使用了，这 里主要列出了 baseda。能操作的部分，像分页，字段过滤

50、查询方面的没冇列出。 package org. chinasb. framework, modules. demo, service;import java.util. list;import org. chinasb. framework, modules, demo, model. demo;public interface demoservice /*增加或更新demo* ©param demo* return*/public boolean save (demo demo);/*批量增加或更新demo* ©param demo* return*/public boo

51、lean save(demo demos);/*删除demo* ©param demo* ©return*/public boolean remove (demo demo);/*批量删除demo* param demos*/public void remove(demo demos);/*根据主键删除demo* ©param id* ©return*/public boolean removebytd(tnteger id);/*批量根据主键删除demo* ©param ids*/public void rcmovcbylds(intcgcr

52、 ids);/*查询demo数据记录集* rcturn*/public list<demo> findall();/*根据主键查询demo* param id* rcturn*/public demo findbyld(integer id);/*批量根据主键杳询demo记录集* ©param ids* ©return*/public dcmo findbylds(integer ids);/*持久化session数据到数据库*/public void flush();demoservicelmpi,接口实现。这里全用注解控制了事务，及演示如何使用basedao

53、 当然强人的basedao并不仅仅这些方法，还有分页等强大的杳询数据功能。人家可 以在 http:/code.qooqle.eom/p/hibernateqenericdao/进行查看。package org. chinasb. framework, modules. demo, service, impl;import java.util. list;import javax. annotation. resource;import org. chinasb. framework, modules, demo. dao. demodao;import org. chinasb. framew

59、69;overridepublic demo findbytds(tnteger ids) return demodao- find (ids);©overridepub11c void flush() demodao. flush ();demoaction,这里演示了查看，增，删功能。也是基于注解的方式，继承了 baseaction。 package org. chinasb. framework, modules, demo, action;import java. util. date;import java.util. list;import javax. annotati
