xwork-conversion.properties 属性文件

com.jamesby.xwork.helloworld.TestType=com.jamesby.xwork.helloworld.TestConvert

Action 文件和测试Chain的Action 文件

public class TestAction implements Action, ModelDriven {
	TestModel book = new TestModel();
	int id;
	public String execute() throws Exception {

		System.out.println("\nAction is invoked............");
		System.out.println("Action:Received Id is " + id);
		System.out.println("Action:Receive Book Title is " + book.getTitle());

		// book = bookDAO.findById(id, Book.class);
		book.setTitle("Action Title");
		if (id < 1000)
			return "failed";
		return "success";
	}
	public TestModel getModel() {
		return book;
	}
	public void setId(int id) {
		this.id = id;
	}
}

public class TestChainAction implements Action, ModelDriven {
	TestModel book = new TestModel();
	int id;
	public String execute() throws Exception {

		System.out.println("\nChain Action is invoked............");
		System.out.println("Chain Action:Received Id is " + id);
		System.out.println("Chain Action:Receive Book Title is " + book.getTitle());

		// book = bookDAO.findById(id, Book.class);
		book.setTitle("Chain Action Title");
		if (id < 2000)
			return "success";
		return "failed";
	}
	public TestModel getModel() {
		return book;
	}
	public void setId(int id) {
		this.id = id;
	}
}

ModelDriven 的模型代码

public class TestModel {
	String id;
	String title;
	public void setId(String id) {
		this.id = id;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public String getId() {
		return this.id;
	}
	public String getTitle() {
		return this.title;
	}
}

Result代码

public class SuccessResult implements Result {
		private TestType param;
		public void setParam(TestType param) {
			this.param = param;
		}
		public void execute(ActionInvocation invocation) {
			System.out.println("\nSuccessResult is invoked..............");
			System.out.println("param is "+param.getValue());
			
			System.out.println("SuccessResult:Received Title is "
					+ invocation.getStack().findValue("title"));
		}
}


public class FailedResult implements Result {
	public void execute(ActionInvocation invocation) {
		System.out.println("\nFailedResult is invoked..............");
		System.out.println("FailedResult:Received Title is "
				+ invocation.getStack().findValue("title"));

	}
}

TypeConvert 文件代码

import java.lang.reflect.Member;
import java.util.Map;

import ognl.DefaultTypeConverter;

public class TestConvert extends DefaultTypeConverter {
	public Object convertValue(Map context, Object target, Member member,
			String propertyName, Object value, Class toType) {
		return new TestType("" + value);
	}
}


public class TestType {
	private String value;
	public String getValue() {
		return value;
	}
	public void setValue(String value) {
		this.value = value;
	}
	public TestType(String value) {
		this.value = value;
	}
}

自定义Interceptor 和 PreResultListener

public class TestInterceptor extends AbstractInterceptor {
	public String intercept(ActionInvocation invocation) throws Exception {
		invocation.addPreResultListener(new PreResultListener() {
			public void beforeResult(ActionInvocation invocation,
					String resultCode) {
				System.out.println("\nPre Result Listerer is invoked........");
				
			}
		});
		return invocation.invoke();
	}
}

Main应用程序代码

public class HelloWorldMain {

	public static void main(String[] args) throws Exception {
		Map paramMap = new HashMap();
		/**
		 * 1000 以下 testAction Failed Result
		 * 1000-2000 testAction testChainAction SuccessResult
		 * 2000 以上 testAction testChainAction Failed Result
		 */
		paramMap.put("id", "500");
		paramMap.put("title", "param title");

		Map context = new HashMap();
		context.put(ActionContext.PARAMETERS, paramMap);

		ConfigurationManager cm = new ConfigurationManager();
		Configuration conf = cm.getConfiguration();
		Container containter = conf.getContainer();
		DefaultActionProxyFactory actionProxyFactory = new DefaultActionProxyFactory();
		actionProxyFactory.setContainer(containter);
		ActionProxy proxy = actionProxyFactory.createActionProxy("/test",
				"testAction", context);
		String result = proxy.execute();
		if ("success".equals(result)) {
			TestAction action = (TestAction) proxy.getAction();
			System.out.println("\nReturn Success.................");
			System.out.println("Return:Return Title is "+action.getModel().getTitle());
		}
		if ("failed".equals(result))
		{
			TestAction action = (TestAction) proxy.getAction();
			System.out.println("\nReturn Failed.................");
			System.out.println("Return:Return Title is "+action.getModel().getTitle());			
		}
	}
}

刚刚学习Xwork2,本来想学struts2 发现需要xwork基础，个人认为学习xwork一是理解它的拦截器机制，二是理解它的ValueStack机制，准备写个xwork2学习小结，希望大家多指点。
