      struts.convention.result.path="/WEB-INF/content/": 结果页面存放的根路径,必须以 "/" 开头。
      struts.convention.action.suffix="Action": action名字的获取 
      struts.convention.action.name.lowercase="true": 是否将Action类转换成小写
      struts.convention.action.name.separator="-": 
      struts.convention.action.disableScanning="false": 是否不扫描类。
      struts.convention.default.parent.package="convention-default":设置默认的父包。
      struts.convention.package.locators="action,actions,struts,struts2": 确定搜索包的路径。
      struts.convention.package.locators.disable="false": 
      struts.convention.package.locators.basePackage="": 

 

写道
包命名习惯来指定Action位置
命名习惯制定结果(支持JSP,FreeMarker等)路径
类名到URL的约定转换
包名到命名空间(namespace)的约定转换
遵循SEO规范的链接地址(即:使用my-action 来替代 MyAction)
基于注解的Action名
基于注解的拦截机(Interceptor)

基于注解的命名空间(Nameespace)
基于注解的XWork包
默认action以及默认的结果(比如:/products 将会尝试寻找com.example.actions.Products 或 com.example.actions.products.Index进行处理)

  struts2零配置详细可看这篇http://javeye.iteye.com/blog/358744

 

spring配置文件从外部加载properties文件

 

	<!-- 定义易受环境影响的变量 -->
	<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
		<property name="ignoreResourceNotFound" value="true" />
		<property name="locations">
			<list>
				<!-- 标准配置 -->
				<value>classpath*:/application.properties</value>
				<!-- 本地开发环境配置 -->
				<value>classpath*:/application.local.properties</value>
				<!-- 服务器生产环境配置 -->
				<value>file:/var/mini-service/application.server.properties</value>
			</list>
		</property>
	</bean>

 

 

基于cxf集成spring开发webservice客户端技术 很简单:

 

<?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:jaxws="http://cxf.apache.org/jaxws" xmlns:cxf="http://cxf.apache.org/core"
	xsi:schemaLocation="http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"
	default-lazy-init="true">

	<description>Apache CXF Web Service Client端配置</description>

	<import resource="classpath:META-INF/cxf/cxf.xml" />
	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
	<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />

	<jaxws:client id="userWebService" serviceClass="org.springside.examples.
miniservice.ws.UserWebService"
		address="http://localhost:8080/mini-service/ws/userservice" />
</beans> <!--这个是webservice客现类接口-->

 

   利用cxf本身API开发webservice 也很简单:

 

 

 

 

String address = BASE_URL + "/ws/userservice";

		JaxWsProxyFactoryBean proxyFactory = new JaxWsProxyFactoryBean();
		proxyFactory.setAddress(address);
		proxyFactory.setServiceClass(UserWebService.class);
            //UserWebService是一个接口
		UserWebService userWebServiceCreated = (UserWebService) proxyFactory.create();

		//(可选)重新设定endpoint address.
		((BindingProvider) userWebServiceCreated).getRequestContext()
		.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
				address);

 

 利用velocity解释动态sql。不再需要为拼sql头痛了。

 

/**
 * 使用Velocity生成内容的工具类.
 * 
 * @author calvin
 */
public class VelocityUtils {

	static {
		try {
			Velocity.init();
		} catch (Exception e) {
			throw new RuntimeException("Exception occurs while initialize the velociy.", e);
		}
	}

	/**
	 * 渲染内容.
	 * 
	 * @param template 模板内容.
	 * @param model 变量Map.
	 */
	public static String render(String template, Map<String, ?> model) {
		try {
			VelocityContext velocityContext = new VelocityContext(model);
			StringWriter result = new StringWriter();
			Velocity.evaluate(velocityContext, result, "", template);
			return result.toString();
		} catch (Exception e) {
			throw new RuntimeException("Parse template failed.", e);
		}
	}
}

   调用:

	/**
	 * 使用Velocity创建动态SQL.
	 */
	public List<User> searchUserByFreemarkerSqlTemplate(Map<String, ?> conditions) {
		String sql = VelocityUtils.render(searchUserSql, conditions);//searchUserSql由spring注入
		logger.info(sql);
		return jdbcTemplate.query(sql, userMapper, conditions);
	}

 

<bean id="userJdbcDao" class="org.springside.examples.showcase.common.dao.UserJdbcDao">
		<property name="searchUserSql">
			<value><![CDATA[
			SELECT id, name, login_name 
			FROM ss_user
			WHERE 1=1
			
			## Dynamic Content
			#if ($loginName)
			AND login_name=:loginName
			#end
			#if ($name)
			AND name=:name
			#end
			
			ORDER BY id
			]]></value>
		</property>
	</bean>

  jdbcTeamplate 使用Bean形式命名参数

 

 

 private static final String INSERT_USER = "insert into SS_USER(id, login_name, name) values(:id, :loginName, :name)";	

 

 

//使用BeanPropertySqlParameterSource将User的属性映射为命名参数.

	BeanPropertySqlParameterSource source = new BeanPropertySqlParameterSource(user);
		jdbcTemplate.update(INSERT_USER, source);

 

  webservice.利用mtom协义传传大文件

 

/**
 * 演示以MTOM附件协议传输Streaming DataHandler的二进制数据传输的方式. 
 * 
 * @author calvin
 */
@XmlType(name = "LargeImageResult", namespace = WsConstants.NS)
public class LargeImageResult extends WSResult {

	private static final long serialVersionUID = 8375875101365439245L;

	private DataHandler imageData;

	@XmlMimeType("application/octet-stream")
	public DataHandler getImageData() {
		return imageData;
	}

	public void setImageData(DataHandler imageData) {
		this.imageData = imageData;
	}
}

 

@WebService(serviceName = "LargeImageService", portName = "LargeImageServicePort", endpointInterface = "org.springside.examples.showcase.ws.server.LargeImageWebService", targetNamespace = WsConstants.NS)
public class LargeImageWebServiceImpl implements LargeImageWebService, ApplicationContextAware {

	private static Logger logger = LoggerFactory.getLogger(LargeImageWebServiceImpl.class);

	private ApplicationContext applicationContext;

	/**
	 * @see LargeImageWebService#getImage()
	 */
	public LargeImageResult getImage() {

		try {
			//采用applicationContext获取Web应用中的文件.
			File image = applicationContext.getResource("/img/logo.jpg").getFile();

			//采用activation的DataHandler实现Streaming传输.
			DataSource dataSource = new FileDataSource(image);
			DataHandler dataHandler = new DataHandler(dataSource);

			LargeImageResult result = new LargeImageResult();
			result.setImageData(dataHandler);
			return result;
		} catch (IOException e) {
			logger.error(e.getMessage(), e);
			return WSResult.buildResult(LargeImageResult.class, WSResult.IMAGE_ERROR, "Image reading error.");
		}

	}

	public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
		this.applicationContext = applicationContext;
	}
}

 

 

 springside很强大,这些主流的大派对,这是不就是我们平常所要找的答案吗?很多技术因为没用,快忘记了,暂时作一个小笔记先。未完待续。。
