Jboss不支持struts spring注解问题

使用struts2注解（struts2-convention-plugin-2.1.8.1）无配置开发的web项目，在tomcat里面运行没有问题，移植到jboss后出现：no result defined for action异常，无法访问action，上google查询资料，找到相应解决方案。 Jboss使用了vfs,于是于是URL的protocol都变成了vfsfile, vfszip等等。 查看xword的源码，在类com.opensymphony.xwork2.util.finder.ClassFinder的 122行左右，里面是写死的，"jar".equals(location.getProtocol(), "file".equals(location.getProtocol()。 解决方法：由于不能影响到非jboss server，如tomcat，所以不好改写ClassFinder。采用改写struts2 convention插件的方案，替换org.apache.struts2.convention.ActionConfigBuilder 如下：

<bean type="org.apache.struts2.convention.ActionConfigBuilder" name="convention" class="com.sunyard.ices.web.actions.jxc.MyActionConfigBuilder"/>


MyActionConfigBuilder类的内容如下：

package com.sunyard.ices.web.actions.jxc;

	}

	@Inject(value = "struts.convention.action.packages", required = false)
	public void setActionPackages(String actionPackages) {
		super.setActionPackages(actionPackages);

		if (!"".equals(actionPackages.trim())) {

		}
	}

		this.packageLocators = packageLocators.split("\\s*[,]\\s*");
	}

	@Override
	@SuppressWarnings("unchecked")
	protected Set<Class> findActions() {

		Set<Class> classes = new HashSet<Class>();

		try {
			// ClassFinder finder = new ClassFinder(getClassLoaderForFinder(), buildUrls(), true);
			ClassFinder finder = new ClassFinder(getClassLoaderInterface(), buildUrls(), true);

			if (actionPackages != null) {

				for (String packageName : actionPackages) {
					Test<ClassFinder.ClassInfo> test = getPackageFinderTest(packageName);
					classes.addAll(finder.findClasses(test));
				}
			}

			// package locators
			if (packageLocators != null) {

					classes.addAll(finder.findClasses(test));
				}
			}

		} catch (Exception ex) {
			if (log.isErrorEnabled()) {
				log.error("Unable to scan named packages", ex);
			}
		}

		return classes;
	}

	private List<URL> buildUrls() throws MalformedURLException {

		List<URL> urls = new ArrayList<URL>();
		URL classesUrl = getClassLoader().getResource(BASE_FILE);

		if (classesUrl == null) {
			throw new IllegalStateException("File " + BASE_FILE
					+ " was not found. The folder WEB-INF/classes discovery base on file classes/" + BASE_FILE + ".");
		}

		String baseFilePath = classesUrl.getFile();
		URL url = new URL("file", "", baseFilePath.substring(0, baseFilePath.indexOf(BASE_FILE)));
		System.out.println(url);
		if (log.isInfoEnabled()) {
			classPath = url.getFile();
			log.info("Struts2 ActionConfigBuilder, classes directory: " + classPath);
		}
		System.out.println("classPath = " + classPath);
		System.out.println(url.toExternalForm());
		urls.add(url);

		return urls;

	}

	/*private ClassLoader getClassLoader() { 
	
	    return Thread.currentThread().getContextClassLoader(); 
	
	}*/

}

，

上述解决了struts2注解开发方式无法访问action的问题

 

但是jboss对spring的支持也有问题，解决方案

 

需引入jboss-spring-int-vfs.jar

在web.xml 加入配置：

<context-param>
        <param-name>contextClass</param-name>
        <param-value>
            org.jboss.spring.vfs.context.VFSXmlWebApplicationContext
        </param-value>
</context-param>

 

这样就不会有问题，如果要在tomcat运行需要去掉web的配置
