SSH项目在Maven下整合

 

  引用
 
 

  

一：Maven的安装：
POM.xml
P：project
O：Object
M：Model
在pom.xml文件中有modelVersion，maven2和maven3一定是4.0.0版本
groupId,artifactId和version是必须写的
maven约定的源文件的目录为：src/main/java/com.sym.HelloWord.java
            资源文件目录为：src/main/resources/spring.xml
            测试源文件目录为：src/test/java/com.sym.Test.java
            测试资源文件目录为：src/test/resources/spring.xml
maven的配置和JDK是完全一样的，也需要配置环境变量
在命令行中输入：mvn -version可以测试maven是否测试成功
在项目的开发的过程中预先设置：
1.对项目右击属性，可以选择为UTF-8
2.右击选择buildpath对JDK进行编辑，选择第三项默认的工作区间JDK版本
3.安装log打印的插件log4e-1.3.3和SVN版本的控制插件site-1.8.7：复制到myeclipse的安装目录下的dropins下，然后重启Myeclipse，右击能够出现share project等选项，表明SVN安装成功。右击出现log4e表明log打印插件安装成功，选择Decare log，引入log4j.properties
log4j.rootLogger=INFO,A1,R

log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.Target=System.out
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=[%c]%m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender 
log4j.appender.R.File=sshe.log
log4j.appender.R.MaxFileSize=10MB
log4j.appender.R.Threshold=ALL
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n
然后在pom.xml加入：
<!-- log4j -->
		<dependency>
			<groupId>log4j</groupId>
			<artifactId>log4j</artifactId>
			<version>1.2.17</version>
二.Spring3的配置：
1.引入spring的jar包，通过在pom.xml文件中依赖。另外查找相关的jar包可以在www.search.maven.org仓库里面查找
<!-- spring3 -->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-core</artifactId>
			<version>3.1.2.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
			<version>3.1.2.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jdbc</artifactId>
			<version>3.1.2.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-beans</artifactId>
			<version>3.1.2.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-web</artifactId>
			<version>3.1.2.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-expression</artifactId>
			<version>3.1.2.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-orm</artifactId>
			<version>3.1.2.RELEASE</version>
		</dependency>
2.在src/main/resources里面加入spring.xml，因为采用的是annotation的方式，示例：
<?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/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-3.0.xsd
">

	<!-- 引入属性文件 -->
	<context:property-placeholder location="classpath:config.properties" />

	<!-- 自动扫描dao和service包(自动注入) -->
	<context:component-scan base-package="sym.dao,sym.service" />

</beans>
serviceImpl中的文件为
@Service("userService")
public class UserServiceImpl implements UserServiceI {

public void test(){
System.out.println("测试成功");
}
}
3,采用Junit测试
需要再pom.xml里面加入junit的jar包
<!-- junit -->
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.11-beta-1</version>
			<scope>test</scope>
		</dependency>
测试代码：
public class TestSpring {

	@Test
	public void test() {
		ApplicationContext ac = new ClassPathXmlApplicationContext(new String[] { "classpath:spring.xml" });
		UserServiceI userService = (UserServiceI) ac.getBean("userService");
		userService.test();
	}

}

三.Struts2和Spring3的整合：
1.在pom.xml中加入struts2的依赖包：
<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-core</artifactId>
			<version>2.3.4.1</version>
//若与hibernate结合需要排除，不结合不需要排除
			<exclusions>
				<exclusion>
					<groupId>javassist</groupId>
					<artifactId>javassist</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
<!--通过spring来控制struts2-->
		<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-spring-plugin</artifactId>
			<version>2.3.4.1</version>
		</dependency>
<!--使用annotation-->
		<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-convention-plugin</artifactId>
			<version>2.3.4.1</version>
		</dependency>
2.在resources中加入struts.xml,内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>

	<!-- 指定由spring负责action对象的创建 -->
	<constant name="struts.objectFactory" value="spring" />
	<!-- 所有匹配*.action的请求都由struts2处理 -->
	<constant name="struts.action.extension" value="action" />
	<!-- 是否启用开发模式 -->
	<constant name="struts.devMode" value="true" />
	<!-- struts配置文件改动后，是否重新加载 -->
	<constant name="struts.configuration.xml.reload" value="true" />
	<!-- 设置浏览器是否缓存静态内容 -->
	<constant name="struts.serve.static.browserCache" value="false" />
	<!-- 请求参数的编码方式 -->
	<constant name="struts.i18n.encoding" value="utf-8" />
	<!-- 每次HTTP请求系统都重新加载资源文件，有助于开发 -->
	<constant name="struts.i18n.reload" value="true" />
	<!-- 文件上传最大值 -->
	<constant name="struts.multipart.maxSize" value="104857600" />
	<!-- 让struts2支持动态方法调用 -->
	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<!-- Action名称中是否还是用斜线 -->
	<constant name="struts.enable.SlashesInActionNames" value="false" />
	<!-- 允许标签中使用表达式语法 -->
	<constant name="struts.tag.altSyntax" value="true" />
	<!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->
	<constant name="struts.dispatcher.parametersWorkaround" value="false" />
<!-- 只有此行是必须 -->
	<package name="basePackage" extends="struts-default">
	</package>
</struts>
3.在web.xml中加入过滤器：
<!-- Struts2配置 -->
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>openSessionInViewFilter</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>

4.代码
@parentPackage（"basePackage"）
//此时访问为XXXproject/userAction!reg.action,若@Namespace("/demo")，则为XXXproject/demo/userAction!reg.action
@Namespace("/")
@Action(value = "userAction")
public class UserAction extends BaseAction implements ModelDriven<User> {
	private User user = new User();

	@Override
	public User getModel() {
		return user;
	}

	private static final Logger logger = Logger.getLogger(UserAction.class);

	private UserServiceI userService;

	public UserServiceI getUserService() {
		return userService;
	}
 //把service注入到action
	@Autowired
	public void setUserService(UserServiceI userService) {
		this.userService = userService;
	}

	public void reg() {
		Json j = new Json();
		try {
			userService.save(user);
			j.setSuccess(true);
			j.setMsg("注册成功！");
		} catch (Exception e) {
			j.setMsg(e.getMessage());
		}

		super.writeJson(j);

	}
}
四.Hibernate的整合
1.在pom.xml中导入jar包
<!-- hibernate4 -->
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-core</artifactId>
			<version>4.1.7.Final</version>
		</dependency>

 
2.在resource中加入文件：spring-hibernate.xml
<?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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.springframework.org/schema/tx 
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/aop

3,写入代码
@Repository("baseDao")
public class BaseDaoImpl<T> implements BaseDaoI<T> {

	private SessionFactory sessionFactory;

	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}

	@Autowired
	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}

	private Session getCurrentSession() {
		return this.sessionFactory.getCurrentSession();
	}

	@Override
	public Serializable save(T o) {
		return this.getCurrentSession().save(o);
	}
}
Action中的代码：

@Service("userService")
public class UserServiceImpl implements UserServiceI {

	private static final Logger logger = Logger.getLogger(UserServiceImpl.class);

	private BaseDaoI<Tuser> userDao;

	public BaseDaoI<Tuser> getUserDao() {
		return userDao;
	}

	@Autowired
	public void setUserDao(BaseDaoI<Tuser> userDao) {
		this.userDao = userDao;
	}

	@Override
	public User save(User user) {
		Tuser t = new Tuser();
		BeanUtils.copyProperties(user, t, new String[] { "pwd" });
		t.setId(UUID.randomUUID().toString());
		t.setCreatedatetime(new Date());
		t.setPwd(Encrypt.e(user.getPwd()));
		userDao.save(t);
		BeanUtils.copyProperties(t, user);
		return user;
	}
4.在web.xml中的配置：
<!-- spring配置文件位置 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
	</context-param>
	<!-- openSessionInView配置 -->

		</init-param>
	</filter>
<!-- spring监听器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 修复数据库监听器 -->
	<listener>
		<listener-class>sy.listener.RepairListener</listener-class>
	</listener>
