spring-cloud-zuul-Gateway Configuration

spring-cloud-zuul-Interface Gateway
1. How to use
1. Add @enablezuulporxy to the startup class
@EnableZuulProxy
@SpringBootApplication
public class Zuulapp {
public static void Main (string[] args) {
New Springapplicationbuilder (Zuulapp.class). Web (True). Run (args);
}
When creating a Zuul filter, you need to create the following:
@Bean
Public Loginfilter Newloginfilter () {
return new Loginfilter ();
}
}
2.application.properties
# routes to ServiceId here the side is bound by the ServiceId address, when the path after adding/api-a/is to access service-a corresponding services.
zuul.routes.api-a.path=/api-zuul/**
Zuul.routes.api-a.serviceid=server-ribbonservice
zuul.routes.api-b.path=/api-zuul1/**
Zuul.routes.api-b.serviceid=server-ribbonservice1

4.Zuul Filter
1. Filter must inherit Zuulfilter base class
Package com.cn.filter;
Import Javax.servlet.http.Cookie;
Import Javax.servlet.http.HttpServletRequest;

Import Com.netflix.zuul.ZuulFilter;
Import Com.netflix.zuul.context.RequestContext;

public class Loginfilter extends zuulfilter{

Public Object Run () {
SYSTEM.OUT.PRINTLN ("Enter Gateway filter ======");
RequestContext RequestContext = Requestcontext.getcurrentcontext ();
HttpServletRequest httpservletrequest = Requestcontext.getrequest ();
TODO auto-generated Method Stub
cookie[] cookie = httpservletrequest.getcookies ();
for (Cookie Cookie2:cookie) {
System.out.println ("Key" + cookie2.getname () + "Value" + cookie2.getvalue ());
if ("token". Equals (Cookie2.getname ())) {
Requestcontext.setsendzuulresponse (TRUE);
Requestcontext.setresponsestatuscode (200);
Requestcontext.setresponsebody ("Current user logon allow operation");
System.out.println ("Get value from cookie" Normal request!! Value "+ cookie2.getvalue ());
return null;
}
}
SYSTEM.OUT.PRINTLN ("Background information------->");
Requestcontext.setsendzuulresponse (FALSE);
Requestcontext.setresponsestatuscode (401);
Requestcontext.setresponsebody ("The current user is not logged in does not allow other actions");
return null;
}
;//Whether the filter is executed, true here, indicating the need to filter
public Boolean shouldfilter () {
TODO auto-generated Method Stub
return true;
}
Priority is 0, the higher the number, the lower the priority level
@Override
public int Filterorder () {
TODO auto-generated Method Stub
return 0;
}

@Override
Public String FilterType () {
TODO auto-generated Method Stub
return "pre";//Front Filter
}

}
