SpringBoot实现跨域访问实现代码-创新互联

当前使用spring版本是4.3.9

import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Component
public class CorsFilter implements Filter {
  @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;
    response.setHeader("Access-Control-Allow-Origin", request.getHeader("origin"));
//    response.setHeader("Access-Control-Allow-Origin", "*");//允许跨域访问的域
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");//允许使用的请求方法，以逗号隔开
    response.setHeader("Access-Control-Max-Age", "3600");// 缓存此次请求的秒数
    //允许使用的请求方法，以逗号隔开
    response.setHeader("Access-Control-Allow-Headers", "x-requested-with,Cache-Control,Pragma,Content-Type,Token");
    response.setHeader("Access-Control-Allow-Credentials","true");//是否允许请求带有验证信息
    filterChain.doFilter(servletRequest, servletResponse);
  }
  @Override
  public void destroy() {
  }
}
