Tapestry+spring+hibernate基本架构

  

Tapestry+spring+hibernate

 

1.     配置tapestry

1)Web.xml中配置tapestry’s servlet

 

<servlet>

    <servlet-name>app</servlet-name>

    <servlet-class>org.apache.tapestry.ApplicationServlet</servlet-class>

</servlet>

 

<servlet-mapping>

    <servlet-name>app</servlet-name>

    <url-pattern>/</url-pattern>

</servlet-mapping>

 

Servlet mapping is associate with the file of hivemodule.xml

 

Note:first u couldn’t add the tapestry-spring.jar

 

2)config application file

 

<application>

       <metakey="org.apache.tapestry.messages-encoding"value="UTF-8"/>

//encoding for tapestry

        <metakey="org.apache.tapestry.page-class-packages"value="tapestry"/>

//html file is associate with java file in the “tapestry” package

</application>

 

And the application file name must be defined the same as the servlet-class name.if u dun do that,u must declare in the application file like this “<application name=’project name’>”

 

3)write your html file and java file

 

Home.html:

<input jwcid=”@insert” value=”ongl:name”>

Home.java:(must extends BasePage)

        Public absact String getName();

        Public abstact void setName(String name);

Note:absact is better for the project.

 

Now u can run and see!

2.    hibernate+spring configuration

1)write a orm file---User.hbm.xml whatever u like(include a PK and name/pwd property).and also do a javabean for it.named User.java in domain package.

 

2)First add tapestry-spring.jar,and add under context into web.xml:

 

<listener>

       <listener-class>

           org.springframework.web.context.ContextLoaderListener

       </listener-class>

    </listener>

    <context-param>

       <param-name>contextConfigLocation</param-name>

       <param-value>/WEB-INF/application.xml</param-value>

</context-param>

 

3)Then create application.xml file:

 

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

           <property name="mappingResources">

              <list>

                  <value>hibernate/User.hbm.xml</value>

              </list>

           </property>

           <property name="hibernateProperties">

              <props>

                  <prop key="hibernate.connection.driver_class">

                     oracle.jdbc.driver.OracleDriver

                  </prop>

//for oracle driver

                  <prop key="hibernate.connection.url">

                     jdbc:oracle:thin:@localhost:1521:jseps

                  </prop>

                  <prop key="hibernate.connection.username">web</prop>

                  <prop key="hibernate.connection.password">web</prop>

                  <prop key="hibernate.dialect">

                     org.hibernate.dialect.Oracle9Dialect

                  </prop>

                  <prop key="hibernate.show_sql">true</prop>

                  <prop key="hibernate.hbm2ddl.auto">update</prop>

//is the key word for auto create table in database by itself.

              </props>

           </property>

    </bean>

 

4)and u can create a service interface and impl class files,one is in service.interface package and another in service.impl package.

 

publicinterface UserService {

    void create(User user);

 

    void update(User user);

 

    void delete(User user);

 

    Collection query();

 

    User load(Long id);

}

 

And UserServiceImpl.java must inject sessionFactory

 

publicclass UserServiceImpl implements UserService {

   

        private SessionFactory sessionFactory;

   

        publicvoid setSessionFactory(SessionFactory sessionFactory) {

           this.sessionFactory = sessionFactory;

        }

 

        publicvoid create(User user) {

HibernateTemplate ht = new HibernateTemplate(this.sessionFactory);

           ht.save(user);

    }

……………………………………………………….

}

 

Now u must add these into application.xml

 

<bean id="userService" class="service.impl.UserServiceImpl">

    <property name="sessionFactory ref="sessionFactory">

</property>

</bean>

 

5) add a table on html

<table cellpadding="0" cellspacing="0" class="grid" width="100%"

    jwcid="tableUser">

        <tr jwcid="@contrib:TableRows">

           <td jwcid="@contrib:TableValues" />

        </tr>

</table>

 

Then Home.java will change:

 

@InjectObject("spring:userService")

    publicabstract UserManager getUserManager();

//inject userService

 

@Component(id = "tableUser", type = "contrib:Table", bindings = {"columns=literal:!name,!pwd","row=currUser", "source=userList"})

    publicabstract IComponent getTableUser();

//for the tableUser component,see more on “http://tapestry.apache.org/tapestry4”

 

    public Collection getUserList(){

       returnthis.getUserManager().query();

    }

    //for source

 

    publicabstract User getCurrUser();

publicabstractvoid setCurrUser(User user);

. . . . . . . . . . . . .

 

To make use of this library, you must include its JAR on the classpath (typically, by copying it into WEB-INF/lib), and extend your application specification, and add a <library> element :

<library id="contrib" specification-path="classpath:/org/apache/tapestry/contrib/

Contrib.library"/>

 

    Now u can add some data in database,and run . . .see the list loaded from database!

3.    spring事务

define a form in new page---create.html

 

<form jwcid="@Form">

        NAME:<input jwcid="@TextField" value="ognl:user.name"/>

    PWD:<input jwcid="@TextField" value="ognl:user.pwd" hidden="true"/>

        <input jwcid="save" value="save"/>

</form>

 

Add a method in create.java

 

public String save(){

       getUserManager().create(getUser());

       return"Home";

}

//can return a string type

 

And add these in application.xml:

 

<bean id="txMgr" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

        <property name="sessionFactory">

            <ref bean="sessionFactory"/>

        </property>

    </bean>

   

    <!-- the txInterceptor bean will get auto-wrapped around all beans matched with the combination of "txAdvisor"+"txAutoProxyCreator" -->

    <bean id="txInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">

        <property name="transactionManager">

            <ref bean="txMgr"/>

        </property>

        <property name="transactionAttributes">

            <props>

                <prop key="*">PROPAGATION_REQUIRED</prop>

            </props>

        </property>

    </bean>

 

    <!-- the txAdvisor advises all matched methods in a given bean against its patterns with its interceptor -->

    <bean id="txAdvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">

        <property name="advice">

            <ref bean="txInterceptor"/>

        </property>

        <property name="patterns">

            <!-- the patterns must match *fully qualified* method names, hence the .* -->

            <list>

                <value>.*</value>

<!—- 将.*的方法包括在TRANSACTION中 -->

            </list>

        </property>

    </bean>

 

    <!-- the txProxyAutoCreator automagically proxies all matched beans with its interceptors if they match any pointcuts -->

    <bean id="txProxyAutoCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">

        <property name="beanNames">

            <list>

                <!-- managers -->

                <value>*Manager</value>

                <value>*Service</value>

<!—- 与以上命名的类文件匹配 -->

            </list>

        </property>

        <property name="interceptorNames">

            <list>

                <value>txAdvisor</value>

            </list>

        </property>

    </bean>
