快速搭建ssh项目环境的具体步骤

2014-06-26 14:25 489 查看

1.1. 项目环境搭建

1.1.1. 框架在项目中功能分配

MyEclipse中添加ssh2 capabilities以及导MyEclipse自带包的操作步骤参考：http://www.doc88.com/p-631428603878.html

1.1.2. 测试Spring

配置Bean

获取Spring配置文件

@Test
public
void testSpring(){
ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
Date date=(Date) context.getBean("date");
System.out.println(date);
}

显示结果：

1.1.3. 测试Hibernate

<hibernate-configuration>
<session-factory>
<propertyname="dialect">org.hibernate.dialect.MrySQLDialect</property>
<propertyname="connection.url">jdbc:mysql://localhost:3306/shop</property>
<propertyname="connection.username">root</property>
<propertyname="connection.password">root</property>
<propertyname="connection.driver_class">com.mysql.jdbc.Driver</property>
<propertyname="myeclipse.connection.profile">mysql5</property>
<property name="javax.persistence.validation.mode">none</property>
</session-factory>
</hibernate-configuration>

l 生成了POJO类如下：

public
class Category implements java.io.Serializable {
private Integerid;
private Stringtype;
private Boolean
hot;

// 省略get set方法

}

l 生成orm映射文件如下：

<hibernate-mapping>
<classname="cn.it.shop.pojo.Category"table="category"catalog="shop">
<idname="id"type="java.lang.Integer">
<columnname="id"/>
<generatorclass="native"/>
</id>
<propertyname="type"type="java.lang.String">
<columnname="type"length="20"/>
</property>
<propertyname="hot"type="java.lang.Boolean">
<columnname="hot"/>
</property>
</class>
</hibernate-mapping>

l 测试Hibernate通过编程式事务来完成事务的管理, 能插入成功则说明环境OK

Session session = HibernateSessionFactory.getSession();
Category category = new Category();
category.setType("A类别");
try {
session.getTransaction().begin();
session.save(category);
session.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
session.getTransaction().rollback();
}finally{
session.close();
}

1.1.4. Spring与Hibernate整合

l 配置数据源

<!—配置成后,可以删除hibernate数据库的连接信息—>
<beanid="dataSource"class="com.mchange.v2.c3p0.ComboPooledDataSource">
<propertyname="jdbcUrl"value="jdbc:mysql://localhost:3306/shop"/>
<propertyname="password"value="root"/>
<propertyname="user"value="root"/>
<propertyname="driverClass"value="com.mysql.jdbc.Driver"/>
</bean>

l LocalSessionFactoryBean

<beanid="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<propertyname="configLocation"value="classpath:hibernate.cfg.xml"/>
<propertyname="dataSource"ref="dataSource"/>
</bean>

l 配置事务管理器transactionManager

<beanid="transactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<propertyname="sessionFactory"ref="sessionFactory"/>
</bean>

l 加入AOP标签

l 配置通知：

<tx:adviceid="advice"transaction-manager="transactionManager">
<tx:attributes>
<tx:methodname="save*"propagation="REQUIRED"rollback-for="Throwable"/>
<tx:methodname="delete*"propagation="REQUIRED"/>
<tx:methodname="update*"propagation="REQUIRED"/>
<tx:methodname="*"read-only="true"/>
</tx:attributes>
</tx:advice>

l 配置AOP切面表达式

<aop:config>
<aop:advisoradvice-ref="advice"pointcut="execution(*
cn.it.shop.service.impl.*.*(..))"/>
</aop:config>

l 测试Spring与Hibernate集成

public
class CategoryServiceImpl implements CategoryService{
private SessionFactorysessionFactory;
public
void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public
void save(Category category){
Session session=sessionFactory.getCurrentSession();
session.save(category);
}
}

l 测试代码如下：

@Test
public
void testHibernate_Spring(){
ApplicationContext context = new ClassPathXmlApplicationContext(
"applicationContext.xml");
CategoryService categoryImpl=(CategoryService)context.getBean("categoryServiceImpl");
Category category = new Category();
category.setCtype("动物33");
categoryImpl.save(category);
}

1.1.5. 测试Struts框架

注意：如果Struts没有与Spring整合则不要添加struts2-spring-plugin添加后,反而创建Action的时候会报错.

l 添加Struts.xml配置文件, 设置基本的参数, 和Struts常量

l 配置Struts过滤器

<filter>
<filter-name>struts</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>

l 创建Action测试

public String login(){
System.out.println("---进入到了Action---");
returnSUCCESS;
}

<packagename="shop"extends="struts-default">

<actionname="users"class="cn.it.shop.action.UsersAction"method="login">
<resultname="success">/success.jsp</result>
</action>
</package>

1.1.6. Spring与Struts整合

把Action 纳入到Spring的容器中.让Spring来创建,这样Action所依赖的业务逻辑类也会注入进来,
struts2-spring-plugin插件中修改了创建Acttion的Bean,改成了StrutsSpring

我们会发现struts2-spring-plugin只有一个类和一个struts-plugin.xml配置文件, 我们打开struts-plugin配置文件源码如下：struts-plugin.xml此配置文件在项目启动的时候会被加载

default.properties：的缺省值设置

### if specified, the default object factory can be overridden here
### Note: short-hand notation is supported in some cases, such as "spring"
### Alternatively, you can provide a com.opensymphony.xwork2.ObjectFactory subclass name here
# struts.objectFactory = spring

### specifies the autoWiring logic when using the SpringObjectFactory.
### valid values are: name, type, auto, and constructor (name is the default)
struts.objectFactory.spring.autoWire = name

l 配置监听器

<context-param>

<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

l 测试Spring与Struts集成

public String login(){
// 如果能注入,则说明完成了Action与业务逻辑类的解耦,整合成功!
System.out.println(usersServiceImpl);
return
SUCCESS;
}
