公司项目中要实现跨域，以下是我的代码实现
package com.lgw.mavenparent.config;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class CorsFilter implements Filter {
private final Log log = LogFactory.getLog(CorsFilter.class);
public CorsFilter(){
log.info("SimpleCORSFilter init");
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse) servletResponse;
String clientOrigin = request.getHeader("origin");
response.addHeader("Access-Control-Allow-Origin", clientOrigin);
if(request.getRequestURI().contains("/findMarGrpPage")
||request.getRequestURI().contains("/itemquery/list")
||request.getRequestURI().contains("/getPersonalizedSetting")
||request.getRequestURI().contains("/manage/single")
||request.getRequestURI().contains("findAllExpInfo")){
}else {
response.setHeader("Access-Control-Allow-Methods", "POST, GET, DELETE, PUT");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "Accept, Content-Type, Origin, Authorization, X-Auth-Tkoen");
response.setHeader("Access-Control-Expose-Headers", "X-Auth-Token");
}
if(request.getMethod().equals("OPTIONS")){
response.setStatus(HttpServletResponse.SC_OK);
}else{
filterChain.doFilter(request, response);
}
}
@Override
public void destroy() {
}
}
