    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!
