基于全注解方式的SSH基础框架

1、这是我为新项目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，晒晒概述：基于struts2.23 + spring2.5.6 + hibernate3.6.4 +hibernate-generic-dao1.0（除了spring，我整合的都是最新的GA包，hibernate-generic-dao是google项目库中一个开源的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，配置文件一目了然。每个功能模块都在modules包下做开发，配置文

2、件统一在resource管理（基实也没多少配置文件，都用注解嘛）。2.无论阅读哪个web项目代码，我都是先从web.xml开始，项目有什么东西一清二楚。我这里将log4j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，也好扩展我某日喜欢加入动态切换数据源做准备。呵呵）。OpenSessionInView，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.xml文件位置，指定扫描注解的action路径。最后是proxool的

3、可视化图形监控，很棒。frameworklog4jConfigLocation/WEB-INF/classes/resources/log4j/pertiespropertyFile/WEB-INF/classes/resources/hibernate/pertiescontextConfigLocationclasspath:resources/spring/applicationContext.xmlorg.springframework.web.util.Log4jConfigListenerorg.chinasb.framework.core.

6、work.modules struts2/*Axool.admin.servlet.AdminServletAdmin/admin.htmlindex.htmlindex.htmindex.jsp3.applicationContext.xml，我想下面注释得也比较清楚了，如果我写错了或理解错了希望指正。4.hiberante配置所需的一些属性，指定方言，开始hibernate缓存等，后面还有一个c3p0的数据连接池属性。你们下载的代码里面，数据源方面我换成了c3p0，因为proxool我配置的是随web启动的，而我又不想改成随spring加

7、载启动。所以我开发中注释掉proxool，以后上线再打开。# hibernatehibernate.dialect=org.hibernate.dialect.MySQLDialecthibernate.show_sql=truehibernate.format_sql=falsehibernate.hbm2ddl.auto=update# hibernate vider_class=org.hibernate.cache.EhCacheProviderhibernate.cache.use_query_cache=falsehibernate.

9、istence.xml，这里就是数据源及事务的一些配置了。事务我使用了cglib类级别的代理注解配置方式，如果你喜欢用jdk接口方式动态的代理，可以去掉 proxy-target-class=true。顺便也保留了声名式事务。 !- xool.ProxoolDriverproxool.default - $hibernate.connection.username $hibernate.connection.password $hibernate.dialect$hibernate.show_sql$hibernate.format_sql$hibe

10、rnate.hbm2ddl.auto$vider_class$hibernate.cache.use_query_cache$hibernate.cache.use_second_level_cache!- -!-!-6.struts.xml,你懂的。 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，映射数据库中的表，每个model一张表，为了适应basedao，每个model还对应每个dao（不要觉得这是

11、麻烦的）。jpa的注解，你们懂的，不解释。package org.chinasb.framework.modules.demo.model;import java.io.Serializable;import java.util.Date;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import org.hibernate.annotations.Cache;i

12、mport org.hibernate.annotations.CacheConcurrencyStrategy;EntityCache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)public class Demo implements Serializable private static final long serialVersionUID = 1L; Id GeneratedValue(strategy = GenerationType.AUTO) private int id; private String title

13、; private String content; private Date publishdate; public int getId() return id; public void setId(int id) this.id = id; public String getTitle() return title; public void setTitle(String title) this.title = title; public String getContent() return content; public void setContent(String content) th

14、is.content = content; public Date getPublishdate() return publishdate; public void setPublishdate(Date publishdate) this.publishdate = publishdate; DemoDao，接口类。我想在多数程序员的项目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，与主键的类型。package org.

15、chinasb.framework.modules.demo.dao;import org.chinasb.framework.core.base.dao.hibernate.GenericDAO;import org.chinasb.framework.modules.demo.model.Demo;public interface DemoDao extends GenericDAO DemoDaoImpl，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;

16、import org.chinasb.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;Repositorypublic class DemoDaoImpl extends BaseDAO implements DemoDao BaseDAO，主要是注入sessionFac

17、tory给hibernate-generic-dao。package org.chinasb.framework.core.base.dao;import java.io.Serializable;import org.chinasb.framework.core.base.dao.hibernate.GenericDAOImpl;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;public class BaseDAO extends Generi

18、cDAOImpl Autowired Override public void setSessionFactory(SessionFactory sessionFactory) super.setSessionFactory(sessionFactory); DemoService，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baseDao能操作的部分，像分页，字段过滤查询方面的没有列出。package org.chinasb.framework.modules.demo.service;import java.util.List;import org.chinasb

19、.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 boolean save(Demo demos); /* * 删除demo * * param demo * return */ public boolean remove(Demo demo); /* * 批量删除dem

20、o * * param demos */ public void remove(Demo demos); /* * 根据主键删除demo * * param id * return */ public boolean removeById(Integer id); /* * 批量根据主键删除demo * * param ids */ public void removeByIds(Integer ids); /* * 查询demo数据记录集 * * return */ public List findAll(); /* * 根据主键查询demo * * param id * return */

21、 public Demo findById(Integer id); /* * 批量根据主键查询demo记录集 * * param ids * return */ public Demo findByIds(Integer ids); /* * 持久化session数据到数据库 */ public void flush();DemoServiceImpl，接口实现。这里全用注解控制了事务，及演示如何使用baseDao。当然强大的baseDao并不仅仅这些方法，还有分页等强大的查询数据功能。大家可以在/p/hibernate-generic-dao/进行

22、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.framework.modules.demo.model.Demo;import org.chinasb.framework.modules.demo.service.DemoService;import org.spring

25、actional(readOnly = false, propagation = Propagation.REQUIRED) public boolean remove(Demo demo) return demoDao.remove(demo); Override Transactional(readOnly = false, propagation = Propagation.REQUIRED) public void remove(Demo demos) demoDao.remove(demos); Override Transactional(readOnly = false, pro

27、verride public Demo findById(Integer id) return demoDao.find(id); Override public Demo findByIds(Integer ids) return demoDao.find(ids); Override public 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.Da
