自定義過慮器ExtendStruts2Filter，爲解決Struts把Webservice請求當普通Action被處理掉的問題。

package com.ccland.filter;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

// 自定義擴展Struts2過濾器，用於解決struts會攔截cxf webservice請求的問題
public class ExtendStruts2Filter extends StrutsPrepareAndExecuteFilter {

	private static Logger log = LoggerFactory
			.getLogger(ExtendStruts2Filter.class);

	@Override
	public void doFilter(ServletRequest req, ServletResponse res,
			FilterChain chain) throws IOException, ServletException {

		try {
			HttpServletRequest request = (HttpServletRequest) req;
			// 判斷是否是向WebService發出的請求
			if (request.getRequestURI().contains("/CXFService")) {
				// 如果是來自向CXFService發出的請求
				chain.doFilter(req, res);
			} else {
				// 默認action請求
				super.doFilter(req, res, chain);
			}
		} catch (Exception e) {
			log.error(e.getMessage());
			e.printStackTrace();
		}
	}

爲支持傳遞複合類型對象

package com.ccland.model;

import java.util.HashMap;
import java.util.List;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "FileStorages")
public class FileStorages {

	private FileStorage fileStorage;
	private List<FileStorage> list;
	private FileStorage[] fileArr;
	private HashMap<String, FileStorage> maps;

	public FileStorage getFileStorage() {
		return fileStorage;
	}

	public void setFileStorage(FileStorage fileStorage) {
		this.fileStorage = fileStorage;
	}

	public List<FileStorage> getList() {
		return list;
	}

	public void setList(List<FileStorage> list) {
		this.list = list;
	}

	public HashMap<String, FileStorage> getMaps() {
		return maps;
	}

	public void setMaps(HashMap<String, FileStorage> maps) {
		this.maps = maps;
	}

	public FileStorage[] getFileArr() {
		return fileArr;
	}

	public void setFileArr(FileStorage[] fileArr) {
		this.fileArr = fileArr;
	}

}

package com.ccland.model;

import java.util.Map;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class MapBean {
	private Map<String, FileStorage> map;

	public Map<String, FileStorage> getMap() {
		return map;
	}

	public void setMap(Map<String, FileStorage> map) {
		this.map = map;
	}
}

打開瀏覽器進行測試：

http://localhost:8080/WebServiceDemo/CXFService/storager/listAll/

運行結果正確：

JS調用測試：

function listAll() {
		$.ajax({
			type : 'get',
			url : '<%=basePath%>CXFService/storager/listAll',
			dataType : 'json',
			data : {},
			success : function(res, status, xhr) {
				alert(res.FileStorages.list[0].fileName);			
			}
		});
	}

返回Json對象：
