tapestry4+spring2+xfire+hibernate3+proxool 开发过程问题一

tapestry 和 spring 的合并，修改hivemodule.xml如下：

xml 代码

<!---->
    <contribution configuration-id="tapestry.url.ServiceEncoders">
        <direct-service-encoder id="direct" stateless-extension="direct" stateful-extension="sdirect"/>
        <page-service-encoder id="page" extension="html" service="page"/>
        <page-service-encoder id="external" extension="external" service="external"/>
        <asset-encoder id="asset" path="/assets"/>
        <extension-encoder id="ext" extension="svc" after="*"/>

        visibility="private">
        <invoke-factory>
            <construct class="com.javaforge.tapestry.spring.SpringApplicationInitializer">
                <set-object property="beanFactoryHolder"
                    value="service:hivemind.lib.DefaultSpringBeanFactoryHolder" />
            <!---->construct>

    <!---->
    <contribution configuration-id="tapestry.init.ApplicationInitializers">
        <command id="spring-context" object="service:SpringApplicationInitializer" />
    <!---->contribution>

即可通过下面方式进行调用。

java 代码

@InjectObject("spring:pointsDao")
public abstract IPointsDao getPointsDao();

还有一种方法：

java 代码

import javax.servlet.ServletContext;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

public class ServiceLocator {
       private Log logger = LogFactory.getLog(this.getClass());
       private ServletContext context = null;
       private ApplicationContext appContext;
       private static ServiceLocator instance = null;

       public ServiceLocator(ServletContext servletContext) {
              context = servletContext;
              appContext = WebApplicationContextUtils.getRequiredWebApplicationContext(getContext());
              logger.info("Spring Service locator bean initialize ...");
       }

       public Object lookupService(String serviceBeanName) {
              return appContext.getBean(serviceBeanName);
       }

       public static synchronized ServiceLocator getInstance(ServletContext servletContext) {
              if (instance == null)
                  instance = new ServiceLocator(servletContext);
              return instance;
       }

       public static synchronized ServiceLocator getInstance() {
              return instance;
       }

       public ServletContext getContext() {
              return context;
       }
}

java 代码

import javax.servlet.ServletException;
import org.springframework.web.context.ContextLoaderServlet;

public class ContextLoaderServletImpl extends ContextLoaderServlet {

    private static final long serialVersionUID = 1L;

    public void init() throws ServletException {
        super.init();
        ServiceLocator.getInstance(getServletContext());
    }
}

在web.xml中添加如下代码

xml 代码

<!-- Spring Config -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext-*.xml</param-value>
</context-param>
<servlet>
    <servlet-name>SpringContextServlet</servlet-name>
    <servlet-class>cn.com.polchina.auction.tapestry.ContextLoaderServletImpl</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>

如下调用即可：

java 代码

ITest it = (ITest) ServiceLocator.getInstance().lookupService("testBean");
