方法1:采用过滤器
然后在web.xml中设置
方法2:采用springmvc 的跨域设置
package cn.mwee.wpos.report.filter; import java.io.IOException; 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; /** * 跨域请求处理 */ public class CrossOriginFilter implements Filter{ private boolean isCross = false; @Override public void destroy() { isCross = false; } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { if(isCross){ HttpServletRequest httpServletRequest = (HttpServletRequest)request; HttpServletResponse httpServletResponse = (HttpServletResponse)response; System.out.println("拦截请求: "+httpServletRequest.getServletPath()); httpServletResponse.setHeader("Access-Control-Allow-Origin", "*"); httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE"); httpServletResponse.setHeader("Access-Control-Max-Age", "0"); httpServletResponse.setHeader("Access-Control-Allow-Headers", "Origin, No-Cache, X-Requested-With, If-Modified-Since, Pragma, Last-Modified, Cache-Control, Expires, Content-Type, X-E4M-With,userId,token"); httpServletResponse.setHeader("Access-Control-Allow-Credentials", "true"); httpServletResponse.setHeader("XDomainRequestAllowed","1"); } chain.doFilter(request, response); } @Override public void init(FilterConfig filterConfig) throws ServletException { String isCrossStr = filterConfig.getInitParameter("IsCross"); isCross = isCrossStr.equals("true")?true:false; System.out.println(isCrossStr); } }
然后在web.xml中设置
<!--跨域请求设置--> <filter> <filter-name>CrossOriginFilter</filter-name> <filter-class>cn.mwee.wpos.report.filter.CrossOriginFilter/filter-class> <init-param> <param-name>IsCross</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CrossOriginFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
方法2:采用springmvc 的跨域设置
<!-- API 接口跨域配置 --> <mvc:cors> <mvc:mapping path="/**" allowed-origins="*" allowed-methods="POST, GET, OPTIONS, DELETE, PUT" allowed-headers="Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With" allow-credentials="true" /> </mvc:cors>
