1.创建crossFilter类
package com.cbsinfo.core.controller; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.PrintWriter; import java.util.HashMap; import java.util.Map; import javax.servlet.Filter; 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; import javax.servlet.http.HttpServletResponse; import org.springframework.stereotype.Component; import com.cbsinfo.core.utils.soap.soapentity.SoapError; import com.cbsinfo.core.utils.soap.soapentity.SoapRequest; import net.sf.json.JSONObject; @Component public class CrossFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void destroy() { } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { System.out.println("跨域请求开始"); SoapRequest sReq=new SoapRequest(); HttpServletRequest httpServletRequest = (HttpServletRequest) request; httpServletRequest.getSession(); HttpServletResponse httpResponse = (HttpServletResponse) response; httpResponse.setHeader("Access-Control-Allow-Origin", "*"); httpResponse.setHeader("Access-Control-Allow-Methods", "*"); httpResponse.setHeader("Access-Control-Max-Age", "3600"); httpResponse.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Connection, User-Agent, Cookie"); httpResponse.setHeader("Access-Control-Allow-Credentials", "true"); httpResponse.setHeader("Content-type", "application/json"); httpResponse.setHeader("Cache-Control", "no-cache, must-revalidate"); String responseSoap=""; StringBuilder reqSoapXml = new StringBuilder(); try { InputStream in = request.getInputStream(); InputStreamReader inReader = new InputStreamReader(in, "utf-8"); BufferedReader bufReader; String line = ( bufReader = new BufferedReader(inReader)) .readLine(); while (line != null) { reqSoapXml.append(line); line = bufReader.readLine(); } System.out.println("reqSoapXml.toString()="+reqSoapXml.toString()); JSONObject soapHead1 =JSONObject.fromObject(reqSoapXml.toString()); Map<String, String> a=new HashMap<String, String>(); JSONObject bodyjs =JSONObject.fromObject(soapHead1.get("body")); System.out.println("js=="+bodyjs); a= bodyjs; sReq.setBody(a); System.out.println("sReq="+sReq.toString()); System.out.println("请求参数="+soapHead1.toString()); request.setAttribute("sReq", sReq); request.setAttribute("reqJson", reqSoapXml.toString()); chain.doFilter(request, httpResponse); }catch (Exception e) { SoapError soapError = new SoapError(); soapError.setErrorCode("300"); soapError.setErrorMsg("解析报文头异常：" + e.getMessage()); response.setCharacterEncoding("UTF-8"); response.setContentType("application/soap+xml;charset=UTF-8"); PrintWriter writer; ( writer = response.getWriter()) .write(responseSoap); writer.flush(); } } }2.web.xml中加载crossFilter
<filter> <filter-name>cors</filter-name> <filter-class>com.cbsinfo.core.controller.CrossFilter</filter-class> </filter> <filter-mapping> <filter-name>cors</filter-name> <url-pattern>/cbs/*</url-pattern> <!--设置哪些接口需要做跨域处理--> </filter-mapping>
