WebWork2.2�l�合spring的Action��试

Tue, 28 Feb 2012 14:53:00 GMT

在WebWork2.2中和Spring的结合变得简单了�Q�WebWork的Action的也可以由Spring来管理。但是如何进行测试了�Q�在google上搜了一下，其代码都是如下�Ş式：

1        Map params = new HashMap();
2        params.put("a", "test");
3               Map paramCtx = new HashMap();
4        paramCtx.put(ActionContext.PARAMETERS, params);
5                ActionProxy proxy = ActionProxyFactory.getFactory().createActionProxy("/organiz", "new_depart", paramCtx, false, false);
6        proxy.setExecuteResult(false);
7        assertEquals(proxy.execute(), "success");
8
9        MyTestAction action = (MyTestAction) proxy.getAction();
10        assertEquals(action.getA(), "test");

该代码执行时会报错误�Q�查看了一下源代码应该加入

1paramCtx.put(ActionContext.DEV_MODE, Boolean.FALSE);

其次需要加载spring的applicationContext�Q�代码如下：

1SpringObjectFactory objectFactory = new SpringObjectFactory();
2        ApplicationContext appContext = new ClassPathXmlApplicationContext("applicationContext.xml");
3        objectFactory.setApplicationContext(appContext);
4        ObjectFactory.setObjectFactory(objectFactory);

webwork的IOC�Q�基�?.1.X版本�Q?br/>webwork的ioc其实在webwork中��用�v来挺方便的，虽然其功能不��强大，但是已经能很好的满��我们一般的需要了�Q�就��我们��用spring 的ioc�Q�如果不使用特别的功能，其一般我们也是基于接口，然后有个set�Ҏ��Q�通过set来注入，没有太多的区别，不同的是webwork的ioc需要依赖xwork�Q�而spring却是依赖spring�q�个容器�?br/>webwork的ioc是怎么�q�行注入的了�Q�我们从代码中进行分析：
首先看看拦截器的代码�Q?br/>
public class ComponentInterceptor extends AroundInterceptor {
//~ Static fields/initializers /////////////////////////////////////////////

public static final String COMPONENT_MANAGER = "com.opensymphony.xwork.interceptor.component.ComponentManager";

//~ Methods ////////////////////////////////////////////////////////////////

protected void after(ActionInvocation dispatcher, String result) throws Exception {
}

protected void before(ActionInvocation dispatcher) throws Exception {
ComponentManager container = (ComponentManager) ActionContext.getContext().get(COMPONENT_MANAGER);

if (container != null) {
container.initializeObject(dispatcher.getAction());
}
}
}

主要的代码用黑体标注出来了，container实际��是�l��g��理器，�q�里是一个ComponentManager接口的实�?DefaultComponentManager�Q�然后调用了该类的方法initializeObject(dispatcher.getAction ());而dispatcher.getAction()实际��是所调用的action对象�Q�我们再来看�?DefaultComponentManager做了什么�?br/>
public void initializeObject(Object obj) {
loadResource(obj, obj.getClass(), this);
}

private Class loadResource(Object resource, Class clazz, DefaultComponentManager dcm) {
// ~由此来判断是否要�q�行依赖注入
boolean resourceNotLoaded = !dcm.loadOrder.contains(resource);

if (resourceNotLoaded) {
Map resources = getResourceDependencies(clazz);

for (Iterator iterator = resources.entrySet().iterator();
iterator.hasNext();) {
Map.Entry mapEntry = (Map.Entry) iterator.next();
Class depResource = (Class) mapEntry.getKey();
DefaultComponentManager newDcm = (DefaultComponentManager) mapEntry.getValue();

try {
ResourceEnablerPair pair = setupAndOptionallyCreateResource(newDcm, depResource);
setupResource(resource, pair.enabler, pair.resource);
} catch (Exception e) {
e.printStackTrace();

if (log.isDebugEnabled()) {
log.debug("Error loading or setting up resource: " + resources.getClass().getName(), e);
}
}
}

dcm.alreadyLoaded.add(clazz);

if (resource instanceof Initializable) {
Initializable initializable = (Initializable) resource;
initializable.init();
}

dcm.resourceInstances.put(clazz, resource);
dcm.loadOrder.add(resource);
}

// now return this class's enabler
Class enabler = (Class) dcm.enablers2.get(clazz);

return enabler;
}

private Map getResourceDependencies(Class resourceClass) {
List interfaces = new ArrayList();
//~ ��所有的interface攑օ�interfaces链表�?br/>addAllInterfaces(resourceClass, interfaces);

Map dependencies = new HashMap();

for (Iterator iterator = interfaces.iterator(); iterator.hasNext();) {
Class anInterface = (Class) iterator.next();

DefaultComponentManager dcm = this;

while (dcm != null) {
Class possibleResource = (Class) dcm.enablers.get(anInterface);

if (possibleResource != null) {
dependencies.put(possibleResource, dcm);

break;
}
dcm = dcm.fallback;
}
}
return dependencies;
}

private void addAllInterfaces(Class clazz, List allInterfaces) {
if (clazz == null) {
return;
}

Class[] interfaces = clazz.getInterfaces();
allInterfaces.addAll(Arrays.asList(interfaces));
addAllInterfaces(clazz.getSuperclass(), allInterfaces);
}

重要的代码都用黑体进行了标注�Q�方法initializeObject中所调用�?span style="FONT-WEIGHT: bold">loadResource(obj, obj.getClass(), this);��执行了查找接口�Q��ƈ注入接口实现�c�L��个过�E��?br/>loadResource首先调用�?span style="FONT-WEIGHT: bold">getResourceDependencies(clazz);�?span style="FONT-WEIGHT: bold">getResourceDependencies又调用了addAllInterfaces(resourceClass, interfaces);addAllInterfaces作用��是取得�q�个�c�d��括这个类的父�cȝ��所有实现的接口�Q��?span style="FONT-WEIGHT: bold">getResourceDependencies�Ҏ��是对这个接口进行过滤，�q�回只是在配�|�中有的接口�?span style="FONT-WEIGHT: bold">setupAndOptionallyCreateResource(newDcm, depResource);�q�行的就是创��些接口的实现�cȝ��对象�Q�这个代码的内容如下�Q?br/>
private ResourceEnablerPair setupAndOptionallyCreateResource(DefaultComponentManager newDcm, Class depResource) throws Exception {
ResourceEnablerPair pair = new ResourceEnablerPair();
Object newResource = newDcm.resourceInstances.get(depResource);

if (newResource == null) {
newResource = ObjectFactory.getObjectFactory().buildBean(depResource);
}

pair.resource = newResource;

Class enabler = loadResource(newResource, depResource, newDcm);
pair.enabler = enabler;

return pair;
}

因�ؓ准备创徏出来的接口实现类对象的接口可能又实现了其他的接口�Q�因此再调用�?span style="FONT-WEIGHT: bold">loadResource(newResource, depResource, newDcm)�?/span>对象创徏了，然后��是注入�q�个对象�Q?span style="FONT-WEIGHT: bold">setupResource(resource, pair.enabler, pair.resource)��是赯��个作用的。代码如下：

private void setupResource(Object resource, Class enabler, Object newResource) {
if (enabler == null) {
return;
}

try {
enabler.getMethods()[0].invoke(resource, new Object[] {newResource});
} catch (Exception e) {
e.printStackTrace();

if (log.isDebugEnabled()) {
log.debug("Error invoking method for resource: " + resource.getClass().getName(), e);
}
}
}

每个接口只有一个set�Ҏ��Q�通过反射机制调用�q�个�Ҏ��创建出来的接口实现对象注入�q�去。整个IOC��完成了�?/p>

在WebWork中进行数据验证其实有好几�U�方式，在此我将他一一列�D出来

一、直接在execute()�Ҏ��中进行验�?/p>

public String execute() {
boolean validationPassed = true;
if (StringUtils.isBlank(user.getName())) {
addActionError(getText("user.name.empty"));
validationPassed = false;
}

if (StringUtils.isBlank(user.getAddress())) {
addActionError(getText("user.address.empty"));
validationPassed = false;
}

return (validationPassed ? SUCCESS : INPUT);
}

因�ؓ整个action是放入OgnlValueStack中的�Q�页面就可以取出�q�些Error�Q�然后显�C�出�?在Input对应的页面加入如下代码：

Errors:

二、是用Validateable接口提供的validate()�Ҏ��q�行验证

ActionSupport���q��承了�q�个接口
public void validate() {
if (StringUtils.isBlank(user.getName())) {
addActionError(getText("user.name.empty"));
}
if (StringUtils.isBlank(user.getAddress())) {
addActionError(getText("user.address.empty"));
}
}

然后在对的action的xwork.xml配置中，使用validationWorkflowStack拦截器，�q�确保有input result�?br/>那么一旦验证出错将会返回input��面�Q�但此时�q�无错误信息提示。将�W�一�U�方式显�C�错误信息代码加入到input ��面�Q�那么错误信息也��显�C�出来�?br/>

三、��用WebWork�?标准形式)的验�?br/>具体的步骤：

1.建立validators.xml文�g�Q�如果没有自己定义的校验器则可以不用建立�?br/>2.建立对应action的检验文件�?br/>���验文件名有两�U�方�?br/>�Q?�Q�Action�c�d��-validation.xml
�Q?�Q�Action�c�d��-Action别名-validation.xml
其中Action别名���是xwork.xml配置中action的name
3.��面使用tag
��面的form和域都���?lt;ww/>tag方式
4.拦截器��用validationWorkflowStack

四、WebWork的客��L��验证
在��用第三种方式时候，通过�?lt;ww:form>里面增加validate="true"卛_��实现客户端验证（�?lt;head>之间增加一�?lt;ww:head/>tag效果更好�Q�里面包括了css的定义）

五、DWR验证
