spring mvc完美支持restful的put提交方式

spring mvc resuful中，put方法好像支持的不太好，不管用註解仍是request.getParameter等方法都獲取不到，我在網上找了一段代碼，修改了下，能夠完美得到參數.

方式1：

方式2：

PageData是用request封裝的，有興趣的能夠問我要代碼。

 

下面看對put的封裝：

import java.util.Collections;
import java.util.Enumeration;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;

public class PutRequestWrapper extends HttpServletRequestWrapper {

	// 自定義解析完成後的參數，放入request中的key

	public final static String CUSTOMER_ATTR_KEY = "customer.attribute.parameter";

	private Map<String, String[]> reqParams;

	public PutRequestWrapper(HttpServletRequest request) {
		super(request);
		reqParams = (Map<String, String[]>) request.getAttribute(CUSTOMER_ATTR_KEY);
	}

	public Map getParameterMap() {
		return reqParams;
	}

	public Enumeration getParameterNames() {
		return Collections.enumeration(reqParams.keySet());
	}

	public String[] getParameterValues(String name) {
		return reqParams.get(name);
	}
}

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URLDecoder;
import java.util.HashMap;
import java.util.Map;

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

public class PutMethodFilter implements javax.servlet.Filter {

	/**
	 * 
	 * Default constructor.
	 * 
	 */
	public PutMethodFilter() {

	}

	/**
	 * 
	 * @seeFilter#destroy()
	 * 
	 */
	public void destroy() {

	}

	/**
	 * 
	 * @seeFilter#doFilter(ServletRequest,ServletResponse, FilterChain)
	 * 
	 */

	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException {
		HttpServletRequest req = (HttpServletRequest) request;
		// PUT請求不能通過request.getparameter()獲得參數
		if ("PUT".equalsIgnoreCase(req.getMethod())) {
			// InputStreamReader
			BufferedReader in = new BufferedReader(new InputStreamReader(request.getInputStream()));
			String org_req_content;
			StringBuilder content = new StringBuilder();
			while ((org_req_content = in.readLine()) != null) {
				content.append(URLDecoder.decode(org_req_content, "UTF-8"));
				Map<String, String[]> map = parseRequestParameter(content.toString());
				request.setAttribute(PutRequestWrapper.CUSTOMER_ATTR_KEY, map);
				// 包裝成自定義的請求
				request = new PutRequestWrapper(req);
				chain.doFilter(request, response);
			}
		}else {
			chain.doFilter(request, response);
		}
	}

	public Map<String, String[]> parseRequestParameter(String content) {
		Map<String, String[]> params = new HashMap<String, String[]>();
		if (content == null || "".equals(content.trim())) {
			return params;
