Learn Spring BOOT, Spring cloud Eureka and security

Interesting, tomorrow to the YANGPU register a spring cloud salon,

Take a closer look at hahaha today.

Eureka Service side:

Eurekaapplication.java

 PackageCom.packtpub.Eureka;Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.SpringBootApplication;ImportOrg.springframework.boot.builder.SpringApplicationBuilder;Importorg.springframework.cloud.netflix.eureka.server.enableeurekaserver;@ Enableeurekaserver@springbootapplication Public classeurekaapplication { Public Static voidMain (string[] args) {//Springapplication.run (Eurekaapplication.class, args);        NewSpringapplicationbuilder (eurekaapplication.class). Web (true). Run (args); }}

Application.properties

server.port=1111eureka.client.register-with-eureka=falseEureka.client.fetch- registry=falseeureka.client.serviceUrl.defaultZone=http://localhost:${ server.port}/eureka/

Eureka Client:

 Packagecom.packtpub.EurekaClient;Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.SpringBootApplication;ImportOrg.springframework.boot.builder.SpringApplicationBuilder;Importorg.springframework.cloud.client.discovery.enablediscoveryclient;@ Enablediscoveryclient@springbootapplication Public classeurekaclientapplication { Public Static voidMain (string[] args) {//Springapplication.run (Eurekaclientapplication.class, args);        NewSpringapplicationbuilder (eurekaclientapplication.class). Web (true). Run (args); }}

Computercontroller.java

 Packagecom.packtpub.EurekaClient;ImportOrg.apache.log4j.Logger;Importorg.springframework.beans.factory.annotation.Autowired;Importorg.springframework.cloud.client.ServiceInstance;Importorg.springframework.cloud.client.discovery.DiscoveryClient;Importorg.springframework.web.bind.annotation.RequestMapping;ImportOrg.springframework.web.bind.annotation.RequestMethod;ImportOrg.springframework.web.bind.annotation.RequestParam;ImportOrg.springframework.web.bind.annotation.RestController; @RestController Public classComputercontroller {Private FinalLogger Logger =Logger.getlogger (GetClass ()); @AutowiredPrivatediscoveryclient Client; @RequestMapping (Value= "/add", method=requestmethod.get) Publicinteger Add (@RequestParam integer A, @RequestParam integer b) {serviceinstance instance=client.getlocalserviceinstance (); Integer R= A +b; Logger.info ("/add, Host:" + instance.gethost () + ", service_id:" + instance.getserviceid () + ", Result:" +R); returnR; }}

Websecurityconfig.java

 Packagecom.packtpub.EurekaClient;Importorg.springframework.beans.factory.annotation.Autowired;Importorg.springframework.context.annotation.Configuration;ImportOrg.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;Importorg.springframework.security.config.annotation.web.builders.HttpSecurity;Importorg.springframework.security.config.annotation.web.configuration.EnableWebSecurity;Importorg.springframework.security.config.annotation.web.configuration.websecurityconfigureradapter;@ Configuration@enablewebsecurity Public classWebsecurityconfigextendsWebsecurityconfigureradapter {@Overrideprotected voidConfigure (Httpsecurity http)throwsException {http. authorizerequests ().

Permitall (); } @Autowired Public voidConfigureglobal (Authenticationmanagerbuilder auth)throwsException {auth. inmemoryauthentication (). Withuser ("User"). Password ("password"). Roles ("User").); }}

Hellocontroller.java

 Packagecom.packtpub.EurekaClient;ImportOrg.springframework.stereotype.Controller;Importorg.springframework.web.bind.annotation.RequestMapping; @Controller Public classHellocontroller {@RequestMapping ("/")     PublicString Index () {return"Index"; } @RequestMapping ("/hello")     PublicString Hello () {return"Hello"; } @RequestMapping ("/login")     PublicString Login () {return"Login"; }}

Application.properties

spring.application.name=compute-serviceserver.port=2222eureka.client.serviceUrl.defaultZone= http://localhost:1111/eureka/
