2.4,Junit
IDE自带jar包三、建立配置文件
3.1,关于Struts2
3.1.1,添加Struts2的配置文件(src):struts.xml
<span style="font-family:KaiTi_GB2312;font-size:18px;"> <?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> <!-- 配置开发环境,当struts.xml配置文件发生修改,会立刻加载,在生产环境下最好不要配置 --> <constant name="struts.configuration.xml.reload" value="true"/> <!-- 会提供更加友好的提示信息 --> <constant name="struts.devModel" value="true"/> <!-- 可使用多个include标签 <include file="struts_user.xml"/>--> <!-- 需要继承struts-default包,这样就拥有的最基本的功能 --> <package name="struts2" extends="struts-default"> </package> </struts> </span>
3.1.2,在web.xml里面配置Struts2的通用拦截器(web-inf)
<span style="font-family:KaiTi_GB2312;font-size:18px;"><filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping></span>
3.2,关于hibernate
<span style="font-family:KaiTi_GB2312;font-size:18px;"><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="foo"> <!-- 数据库连接信息 --> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/angeloa</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">Angel0626</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <!-- 其他配置 --> <property name="hibernate.show_sql">true</property> <!-- 导入映射文件 --> </session-factory> </hibernate-configuration></span>
3.3,关于Spring
首先,建立一个文件:applicationContext-common.xml,配置数据库事务等方面的东西
<span style="font-family:KaiTi_GB2312;font-size:18px;"><?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <!-- 配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> </bean> <!-- 配置事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory"> <ref bean="sessionFactory" /> </property> </bean> <!-- 配置事务的传播特性(配置Advice) --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" rollback-for="java.lang.Exception" /> <tx:method name="del*" propagation="REQUIRED" rollback-for="java.lang.Exception" /> <tx:method name="update*" propagation="REQUIRED" rollback-for="java.lang.Exception" /> <tx:method name="*" propagation="REQUIRED" read-only="true" /> </tx:attributes> </tx:advice> <!-- 那些类那些方法使用事务 --> <aop:config> <aop:pointcut id="allManagerMethod" expression="execution(* cn.Angel.ssh.service.*.*(..))" /> <aop:advisor pointcut-ref="allManagerMethod" advice-ref="txAdvice" /> </aop:config> </beans></span>
然后,建立一个主文件,配置spring:applicationContext.xml
<span style="font-family:KaiTi_GB2312;font-size:18px;"><?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <!-- 启用AspectJ对Annotation的支持 --> <aop:aspectj-autoproxy /> <!-- 强制使用CGLIB代理 --> <!-- <aop:aspectj-autoproxy proxy-target-class="true" /> --> <!--配置事务 --> <import resource="applicationContext-common.xml" /> </beans></span>
最后,在web.xml文件中配置spring监听:
<span style="font-family:KaiTi_GB2312;font-size:18px;"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param></span>
3.4,关于日志
引入log4j.properties
<span style="font-family:KaiTi_GB2312;font-size:18px;">log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.rootLogger=<span style="color:#ff0000;">warn</span>, stdout log4j.logger.org.hibernate=info log4j.logger.org.hibernate.type=info log4j.logger.org.hibernate.tool.hbm2ddl=debug </span>
注意红色标记的部分:配置合适的日志提醒等级,当前配置的为warn,也就是会打印出warn,以及warn以上的错误信息。
四、完成框架的剩余部分
4.1,实体
4.1.1,编写实体类User.java
<span style="font-family:KaiTi_GB2312;font-size:18px;">package cn.Angel.ssh.domain; public class User { private String id; private String userName; private String password; private String userCode; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getUserCode() { return userCode; } public void setUserCode(String userCode) { this.userCode = userCode; } } </span>
4.1.2,编写实体的映射文件user.hbm.xml
<span style="font-family:KaiTi_GB2312;font-size:18px;"><?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="cn.Angel.ssh.domain.User" table="t_user"> <id name="id" length="50"> <generator class="uuid" /> </id> <property name="userCode" length="18" /> <property name="userName" length="10" /> <property name="password" length="16" /> </class> </hibernate-mapping></span>
4.1.3,在Hibernate配置文件中,添加实体映射文件的引入
<span style="font-family:KaiTi_GB2312;font-size:18px;"><!-- 导入映射文件 --> <mapping resource="cn/Angel/ssh/domain/User.hbm.xml" /></span>
4.1.4,编写ExportDB类
<span style="font-family:KaiTi_GB2312;font-size:18px;">package cn.Angel.ssh.domain; import org.hibernate.cfg.Configuration; import org.hibernate.tool.hbm2ddl.SchemaExport; public class ExportDb { public static void main(String[] args) { // 默认读取hibernate.cfg.xml文件 Configuration cfg = new Configuration().configure(); SchemaExport export = new SchemaExport(cfg); export.create(true, true); } }</span>
执行方法,根据实体生成表
4.2,建立Dao层
4.2.1,建立IUser接口
<span style="font-family:KaiTi_GB2312;font-size:18px;">package cn.Angel.ssh.dao; import cn.Angel.ssh.domain.User; public interface IUser { boolean login(User user); } </span>
4.2.2,建立UserImpl类,实现接口IUser
<span style="font-family:KaiTi_GB2312;font-size:18px;">package cn.Angel.ssh.dao; import java.util.List; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; import cn.Angel.ssh.domain.User; public class UserImpl extends HibernateDaoSupport implements IUser { @SuppressWarnings("unchecked") public boolean login(User user) { List<User> list = (List<User>) getHibernateTemplate().find( " from User where userCode='" + user.getUserCode() + "' and password='" + user.getPassword() + "' "); if (list.size() > 0) { return true; } else { return false; } } }</span>
4.2.3,在applicationContext.xml中配置Dao层的注入
注:可以仿照applicationContext-common文件一样为dao层建立一个xml文件,然后用import引入
<span style="font-family:KaiTi_GB2312;font-size:18px;"> <!-- 注入Dao层 --> <bean id="userDao" class="cn.Angel.ssh.dao.UserImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean></span>
4.3,建立Service层
4.3.1,建立UserService接口
<span style="font-family:KaiTi_GB2312;font-size:18px;">package cn.Angel.ssh.service; import cn.Angel.ssh.domain.User; public interface UserService { boolean login(User user); }</span>
4.3.2,建立UserServiceImpl类,实现UserService接口
<span style="font-family:KaiTi_GB2312;font-size:18px;">package cn.Angel.ssh.service; import cn.Angel.ssh.dao.UserImpl; import cn.Angel.ssh.domain.User; public class UserServiceImpl implements UserService{ //注入dao层 private UserImpl userDao; public UserImpl getUserDao() { return userDao; } public void setUserDao(UserImpl userDao) { this.userDao = userDao; } public boolean login(User user) { return userDao.login(user); } }</span>
4.3.3,在applicationContext.xml文件中配置service层注入
<span style="font-family:KaiTi_GB2312;font-size:18px;"><!-- 注入Service层 --> <bean id="userService" class="cn.Angel.ssh.service.UserServiceImpl"> <property name="userDao" ref="userDao" /> </bean></span>
4.4,建立web层
4.4.1,建立UserAction.java类,控制页面的访问
<span style="font-family:KaiTi_GB2312;font-size:18px;">package cn.Angel.ssh.web; import cn.Angel.ssh.domain.User; import cn.Angel.ssh.service.UserService; import com.opensymphony.xwork2.ActionSupport; import com.opensymphony.xwork2.ModelDriven; @SuppressWarnings("serial") public class UserAction extends ActionSupport implements ModelDriven<User> { private User user = new User(); public User getModel() { return user; } private UserService userService; public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } public String login() { boolean flag = userService.login(user); if (flag == true) { return "loginSuccess"; } else { return "loginFail"; } } }</span>
4.4.2,在applicationContext.xml文件中配置action注入
<span style="font-family:KaiTi_GB2312;font-size:18px;"><!-- 用户模块的Action --> <bean id="userAction" class="cn.Angel.ssh.web.UserAction" scope="prototype" > <property name="userService" ref="userService" /> </bean></span>
4.4.3,在Struts.xml文件中,配置userAction的跳转页面
<span style="font-family:KaiTi_GB2312;font-size:18px;"><!-- 需要继承struts-default包,这样就拥有的最基本的功能 --> <package name="struts2" extends="struts-default"> <action name="user_*" class="userAction" method="{1}"> <!-- <result>标签的那么属性,如果不配置,那么缺省值为success --> <result name="loginSuccess">/login_success.jsp</result> <result name="loginFail">/login_error.jsp</result> </action> </package></span>
4.5,建立页面
4.5.1,login.jsp
<span style="font-family:KaiTi_GB2312;font-size:18px;"><body> <form action="user_login.action"> 用户代码:<input type="text" name="userCode"> 用户密码:<input type="password" name="password"> <input type="submit" value="登录"> </form> </body></span>
4.5.2,login_success.jsp、login_error.jsp
<span style="font-family:KaiTi_GB2312;font-size:18px;"><body> 登录成功!<br> </body></span>
附:程序结构图
4.6,将程序添加至tomcat或者其他服务器,启动
访问:localhost:8080/AngelSSH/login.jsp
五、总结
按照以上的步骤来,最终一定能实现SSH的简单搭建。本篇博客介绍的是注入的方法,还可以使用注解。引入了各种jar包,也可以通过maven仓库来解决。接下来会继续总结SSH框架搭建过程中的一些问题。呼呼,这是我第十一遍搭,在第9次之后,终于能搭一遍成一遍了,做个总结,供自己参考!
