��Z��maven的多框架和多视图融合技�?Struts1、Struts2、Spring、SpringMVC、Hibernate、Ibatis、MyBatis、Spring Data JPA、DWR)

雪山飞鹄 — Tue, 25 Sep 2012 03:40:00 GMT

该项目基于maven3.0构徏的，��目中融合了Struts1、Struts2、Spring、SpringMVC、Hibernate、Ibatis、MyBatis、Spring Data JPA、Spring JDBC、Spring DWR。页面展现这里��用Struts1、Struts2、SpringMVC�Q�jsp视图、velocity视图、freemarker视图、pdf视图、excel视图、xml视图、json视图�{�）。是一个综合性行的项目。该��目后期会陆�l�集成Spring的一些好的框架进来比如说Spring Web Flow、Spring Security 、Jbpm、WebService、Compass、Solr、nutch�{�。��M��是一个综合性的��目。该��目不处理业务，主要是把目前自己工作中用到过的各�U�框架糅合到一个项目中。纯�_Ҏ(gu��)��一个jee框架的糅合，主要是介�l�各�U�技术�?/p>

介绍下目前��用的各个框架的版本信�?/p>

Struts1 1.3.10

Struts2 2.3.8

Spring 3.2.0.RELEASE

Hibernate 4.2.0.Final

Ibatis 2.3.4.726

MyBatis 3.1.1

Spring Data JPA 1.3.0.RELEASE

DWR 3.0.M1

��目中的持久化框架sql语句的跟�t�采用了log4jdbc4�l�合log4j�Q�在控制台可以看到完整的sql语句�?/p>

该项目中使用到的技术均与Spring已集成。除了DWR与Spring集成使用xml文�g中配�|�bean�?其他的bean均��用注解完善。每一个与数据库有关的都有事务处理�?/p>

velocity模板加蝲

雪山飞鹄 — Thu, 11 Nov 2010 05:29:00 GMT

velocity使用基本来说比较��单，但在加蝲模板时老出问题�Q�很多初学者经�怼�遇到找不到模板这�U�异常。本文就针对目前常用的三�U�模板加载方式做以说明�?br /> velocity官方帮助文档
其工�E�目录结构大致�ؓ
�Ҏ(gu��)��下蝲�C�Z��代码

一、velocity默认的加载方�?文�g加蝲方式)

package com.velocity.test;

import java.io.StringWriter;
import java.util.Properties;

import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;

/**
* 从文件中加蝲模板文�g,即velocity默认的模板文件加载方�?br /> * @author welcome
*
*/
public class LoaderFromFile {

    public static void main(String[] args) throws Exception{
        //初始化参�?/span>
        Properties properties=new Properties();
        //讄��velocity资源加蝲方式为file
        properties.setProperty("resource.loader", "file");
        //讄��velocity资源加蝲方式为file时的处理�c?/span>
        properties.setProperty("file.resource.loader.class", "org.apache.velocity.runtime.resource.loader.FileResourceLoader");
        //实例化一个VelocityEngine对象
        VelocityEngine velocityEngine=new VelocityEngine(properties);

        //实例化一个VelocityContext
        VelocityContext context=new VelocityContext();
        //向VelocityContext中放入键�?/span>
        context.put("username", "张三");
        context.put("password", "123456789");
        context.put("age", "20");
        context.put("address", "陕西西安");
        context.put("blog", "http://blogjava.net/sxyx2008");
        //实例化一个StringWriter
        StringWriter writer=new StringWriter();
        //从vm目录下加载hello.vm模板,在eclipse工程中该vm目录与src目录�q��
        velocityEngine.mergeTemplate("vm/hello.vm", "gbk", context, writer);
        System.out.println(writer.toString());

    }
}

二、从�c��\径加载模板文�?br />

package com.velocity.test;

import java.io.StringWriter;
import java.util.Properties;

import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;

/**
* 从class(�c��\�?中加载模板文�?br /> * @author welcome
*
*/
public class LoaderFromClass {

    public static void main(String[] args) throws Exception{
        //初始化参�?/span>
        Properties properties=new Properties();
        //讄��velocity资源加蝲方式为class
        properties.setProperty("resource.loader", "class");
        //讄��velocity资源加蝲方式为file时的处理�c?/span>
        properties.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
        //实例化一个VelocityEngine对象
        VelocityEngine velocityEngine=new VelocityEngine(properties);

        //实例化一个VelocityContext
        VelocityContext context=new VelocityContext();
        //向VelocityContext中放入键�?/span>
        context.put("username", "张三");
        context.put("password", "123456789");
        context.put("age", "20");
        context.put("address", "陕西西安");
        context.put("blog", "http://blogjava.net/sxyx2008");
        //实例化一个StringWriter
        StringWriter writer=new StringWriter();

        //从src目录下加载hello.vm模板
        //假若在com.velocity.test包下有一个hello.vm文�g,那么加蝲路径为com/velocity/test/hello.vm
        velocityEngine.mergeTemplate("com/velocity/test/hello.vm", "gbk", context, writer);

        //velocityEngine.mergeTemplate("hello.vm", "gbk", context, writer);
        System.out.println(writer.toString());
    }
}

三、从jar文�g中加载模板文�?br />

package com.velocity.test;

import java.io.StringWriter;
import java.util.Properties;

import org.apache.velocity.VelocityContext;
import org.apache.velocity.app.VelocityEngine;

/**
* 从jar文�g中加载模板文�?br /> * @author welcome
*
*/
public class LoaderFromJar {

    public static void main(String[] args) throws Exception{
        //初始化参�?/span>
        Properties properties=new Properties();
        //讄��velocity资源加蝲方式为jar
        properties.setProperty("resource.loader", "jar");
        //讄��velocity资源加蝲方式为file时的处理�c?/span>
        properties.setProperty("jar.resource.loader.class", "org.apache.velocity.runtime.resource.loader.JarResourceLoader");
        //讄��jar包所在的位置
        properties.setProperty("jar.resource.loader.path", "jar:file:WebRoot/WEB-INF/lib/vm.jar");
        //实例化一个VelocityEngine对象
        VelocityEngine velocityEngine=new VelocityEngine(properties);

        //实例化一个VelocityContext
        VelocityContext context=new VelocityContext();
        //向VelocityContext中放入键�?/span>
        context.put("username", "张三");
        context.put("password", "123456789");
        context.put("age", "20");
        context.put("address", "陕西西安");
        context.put("blog", "http://blogjava.net/sxyx2008");
        //实例化一个StringWriter
        StringWriter writer=new StringWriter();
        //�?WebRoot/WEB-INF/lib/vm.jar中加载hello.vm模板  vm.jar的目录结构�ؓvm/hello.vm
        velocityEngine.mergeTemplate("vm/hello.vm", "gbk", context, writer);
        System.out.println(writer.toString());
    }
}

误��者朋友自行运行程序�?br /> �Ҏ(gu��)��下蝲�C�Z��代码
