详解springboot设置cors跨域请求的两种方式

1、第一种：

public class corsfilter extends onceperrequestfilter {

  static final string origin = "origin";

  protected void dofilterinternal(
    httpservletrequest request, 
    httpservletresponse response, 
    filterchain filterchain) throws servletexception, ioexception {
  
    string origin = request.getheader(origin);
  
    response.setheader("access-control-allow-origin", "*");//* or origin as u prefer
    response.setheader("access-control-allow-credentials", "true");
    response.setheader("access-control-allow-methods", "put, post, get, options, delete");
    response.setheader("access-control-max-age", "3600");
    response.setheader("access-control-allow-headers", "content-type, authorization");
  
    if (request.getmethod().equals("options"))
      response.setstatus(httpservletresponse.sc_ok);
    else 
      filterchain.dofilter(request, response);
  
  }
}
@bean
public corsfilter corsfilter() throws exception {
  return new corsfilter();
}

http
  .addfilterbefore(corsfilter(), usernamepasswordauthenticationfilter.class)
  .addfilterbefore(authenticationtokenfilterbean(), usernamepasswordauthenticationfilter.class)
  .headers()
  .cachecontrol();

2、第二种：

@configuration
public class corsconfig {
  @bean
  public filterregistrationbean corsfilter() {
    urlbasedcorsconfigurationsource source = new urlbasedcorsconfigurationsource();
    corsconfiguration config = new corsconfiguration();
    config.setallowcredentials(true);
    // 设置你要允许的网站域名，如果全允许则设为 *
    config.addallowedorigin("http://localhost:4200");
    // 如果要限制 header 或 method 请自行更改
    config.addallowedheader("*");
    config.addallowedmethod("*");
    source.registercorsconfiguration("/**", config);
    filterregistrationbean bean = new filterregistrationbean(new corsfilter(source));
    // 这个顺序很重要哦，为避免麻烦请设置在最前
    bean.setorder(0);
    return bean;
  }
}
