基于全注解方式的SSH框架

来源:互联网 发布:js new date 少一天 编辑:程序博客网 时间:2024/05/18 13:25

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的可视化图形监控,很棒。

3.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。

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><!-- 使用 annotation --><context:annotation-config /><!-- 使用 annotation 自动注册bean,并检查@Controller, @Service, @Repository注解已被注入 --><context:component-scan base-package="org.chinasb.framework.modules" /><!-- hibernate属性配置 --><context:property-placeholder location="classpath:resources/hibernate/hibernate.properties"/><!-- Hibernate 配置管理 --><import resource="applicationContext-persistence.xml" /></beans>
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 cachehibernate.cache.provider_class=org.hibernate.cache.EhCacheProviderhibernate.cache.use_query_cache=falsehibernate.cache.use_second_level_cache=true## C3P0 configurationhibernate.connection.driver_class=com.mysql.jdbc.Driverhibernate.connection.url=jdbc:mysql://localhost:3306/chinasb??useUnicode=true&characterEncoding=utf-8hibernate.connection.username=roothibernate.connection.password=root
5.applicationContext-persistence.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。

<?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"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd"><!-- Proxool 数据源 --><!-- <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName"><value>org.logicalcobwebs.proxool.ProxoolDriver</value></property><property name="url"><value>proxool.default</value></property></bean> --><!-- C3P0 数据源 -->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <property name="driverClass" value="${hibernate.connection.driver_class}"/>        <property name="jdbcUrl" value="${hibernate.connection.url}"/>        <property name="properties">            <props>                <prop key="user">${hibernate.connection.username}</prop>                <prop key="password">${hibernate.connection.password}</prop>            </props>        </property>    </bean>    <!-- SessionFactory --><bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="packagesToScan" value="org.chinasb.framework.modules.*.model"/><property name="hibernateProperties"><props><prop key="hibernate.dialect">${hibernate.dialect}</prop><prop key="hibernate.show_sql">${hibernate.show_sql}</prop><prop key="hibernate.format_sql">${hibernate.format_sql}</prop><prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop><prop key="hibernate.cache.provider_class">${hibernate.cache.provider_class}</prop><prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop><prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop></props></property></bean><!-- 配置事务管理 --><bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean><!-- 配置注解实现管理事务(cglib:proxy-target-class="true") --><tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" /><!-- 指定使用cglib --><!-- <aop:aspectj-autoproxy proxy-target-class="true" />  --><!-- 配置事务的传播特性 --><!--<tx:advice id="txAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="add*" propagation="REQUIRED" /><tx:method name="edit*" propagation="REQUIRED" /><tx:method name="remove*" propagation="REQUIRED" /><tx:method name="save*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="delete*" propagation="REQUIRED" /><tx:method name="batchUpdate" propagation="REQUIRED" /><tx:method name="*" read-only="true" /></tx:attributes></tx:advice>--><!-- 配置事务的切入点 --><!--<aop:config><aop:pointcut id="targetMethod" expression="execution(* org.chinasb.framework.modules..service.*.*(..))" /><aop:advisor advice-ref="txAdvice" pointcut-ref="targetMethod" /></aop:config>--></beans>
6.struts.xml,你懂的。
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd"><struts>    <!-- 开启使用开发模式,详细错误提示 -->    <constant name="struts.devMode" value="false" />    <!-- 将对象交给spring管理 -->    <constant name="struts.objectFactory" value="spring" />    <!-- 指定资源编码类型 -->    <constant name="struts.i18n.encoding" value="UTF-8" /><!-- 指定每次请求到达,重新加载资源文件 -->    <constant name="struts.i18n.reload" value="false" />    <!-- 指定每次配置文件更改后,自动重新加载 -->    <constant name="struts.configuration.xml.reload" value="false" />    <!-- 国际化资源文件 -->    <constant name="struts.custom.i18n.resources" value="resources/content/Language" />    <!-- 默认后缀名 -->    <constant name="struts.action.extension" value="do,action,jhtml,," /><!-- Struts Annotation -->    <constant name="actionPackages" value="org.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;import org.hibernate.annotations.CacheConcurrencyStrategy;@Entity@Cache(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;    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) {this.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.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<Demo, Integer> {}
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;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<Demo, Integer> implements DemoDao {}
BaseDAO,主要是注入sessionFactory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<T, ID extends Serializable> extends GenericDAOImpl<T, ID> {    @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.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demo     *     * @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<Demo> findAll();    /**     * 根据主键查询demo     *     * @param id     * @return     */    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http://code.google.com/p/hibernate-generic-dao/ 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.framework.modules.demo.model.Demo;import org.chinasb.framework.modules.demo.service.DemoService;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;@Service@Transactional(readOnly = true, propagation = Propagation.SUPPORTS)public class DemoServiceImpl implements DemoService {    @Resource    private DemoDao demoDao;    @Override    @Transactional(readOnly = false, propagation = Propagation.REQUIRED)    public boolean save(Demo demo) {return demoDao.save(demo);    }    @Override    @Transactional(readOnly = false, propagation = Propagation.REQUIRED)    public boolean[] save(Demo[] demos) {return demoDao.save(demos);    }    @Override    @Transactional(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, propagation = Propagation.REQUIRED)    public boolean removeById(Integer id) {return demoDao.removeById(id);    }    @Override    @Transactional(readOnly = false, propagation = Propagation.REQUIRED)    public void removeByIds(Integer[] ids) {demoDao.removeByIds(ids);    }    @Override    public List<Demo> findAll() {return demoDao.findAll();    }    @Override    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.Date;import java.util.List;import javax.annotation.Resource;import org.apache.struts2.convention.annotation.Action;import org.apache.struts2.convention.annotation.Result;import org.chinasb.framework.core.base.action.BaseAction;import org.chinasb.framework.modules.demo.model.Demo;import org.chinasb.framework.modules.demo.service.DemoService;import org.springframework.stereotype.Controller;@Controllerpublic class DemoAction extends BaseAction {    private static final long serialVersionUID = 1L;    @Resource    private DemoService demoService;    @Action(value = "/demoAction", results = { @Result(name = SUCCESS, location = "/manager/modules/demo/index.jsp") })    @Override    public String execute() {List<Demo> demoList = demoService.findAll();httpServletRequest.setAttribute("DEMO_LIST", demoList);return SUCCESS;    }    @Action(value = "/demoAddAction", results = { @Result(name = SUCCESS, location = "/demoAction", type = "redirect") })    public String add() {Demo demo = new Demo();demo.setTitle(httpServletRequest.getParameter("title"));demo.setContent(httpServletRequest.getParameter("content"));demo.setPublishdate(new Date());demoService.save(demo);return SUCCESS;    }    @Action(value = "/demoDeleteAction", results = { @Result(name = SUCCESS, location = "/demoAction", type = "redirect") })    public String delete() {demoService.removeById(Integer.parseInt(httpServletRequest.getParameter("id")));return SUCCESS;    }}
 BaseAction,这里只封装了基本的request,reponse,context,session,大家按需要继续完善。
package org.chinasb.framework.core.base.action;import java.util.Map;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;import org.apache.struts2.interceptor.SessionAware;import org.apache.struts2.util.ServletContextAware;import com.opensymphony.xwork2.ActionSupport;public class BaseAction extends ActionSupport implements ServletContextAware,ServletResponseAware, ServletRequestAware, SessionAware {    private static final long serialVersionUID = 1L;    protected ServletContext servletContext;    protected HttpServletRequest httpServletRequest;    protected HttpServletResponse httpServletResponse;    protected HttpSession httpSession;    protected Map<String, Object> session;    @Override    public void setServletContext(ServletContext context) {this.servletContext = context;    }    @Override    public void setServletResponse(HttpServletResponse response) {this.httpServletResponse = response;    }    @Override    public void setServletRequest(HttpServletRequest request) {this.httpServletRequest = request;this.httpSession = request.getSession();    }    @Override    public void setSession(Map<String, Object> session) {this.session = session;    }}

最后就是测试用例了,这里使用了经典的junit4.4版本,依然是注解方式。

BaseTestTemplate,大家都不想每个用例都去写一次读取applicationContext吧,把一些公用的东西封装起来吧。

package org.chinasb.framework.core.base.test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.context.transaction.TransactionConfiguration;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = { "classpath:resources/spring/applicationContext.xml" })@TransactionConfiguration(defaultRollback = false)@Transactional(readOnly = true, propagation = Propagation.SUPPORTS)public class BaseTestTemplate {}
DemoActionTest,简单的测试用例,这里只是为了说明如何在这个框架里进行单元测试。所以我的目的达到了,简单吧。
package org.chinasb.framework.modules.demo.action;import java.util.Date;import javax.annotation.Resource;import org.chinasb.framework.core.base.test.BaseTestTemplate;import org.chinasb.framework.modules.demo.model.Demo;import org.chinasb.framework.modules.demo.service.DemoService;import org.junit.After;import org.junit.Before;import org.junit.Test;import org.springframework.test.context.transaction.AfterTransaction;import org.springframework.test.context.transaction.BeforeTransaction;public class DemoActionTest extends BaseTestTemplate {    @Resource    private DemoService demoService;    @Before    public void setUp() throws Exception {System.out.println("测试开始");    }    @After    public void tearDown() throws Exception {System.out.println("测试结束");    }    @BeforeTransaction    public void beforeTransaction() {System.out.println("事务开始");    }    @AfterTransaction    public void afterTransaction() {System.out.println("事务结束");    }    @Test    public void testInsert() {Demo demo = new Demo();demo.setTitle("junit-test");demo.setContent("junit-content");demo.setPublishdate(new Date());demoService.save(demo);    }    @Test    public void testInsertMore() {Demo[] demos = new Demo[10];for (int i = 0; i < 10; i++) {    Demo demo = new Demo();    demo.setTitle("junit-test" + i);    demo.setContent("junit-content" + i);    demo.setPublishdate(new Date());    demos[i] = demo;}demoService.save(demos);    }}

众望所归,出图:

 

 

终于写完了,好累啊。下一步跟汪兄商量如何完美整合他那个强大的数据级权限中间件(ralasafe),这样在未来一投入使用即附带有权限控制,多爽。好了,大家看得也累,喜欢的,不喜欢的都出来拍拍砖吧。不对的地方,请各位N人多多指正。
