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!
