spring cloud版本升级记录(1)注册中心升级到Hoxton.SR12

     2018年开始做spring cloud微服务，选定版本是Finchley.RC2，时至今日，spring cloud版本从Finchley经历了GreenWich、Hoxton、2020.0.x、2021.0.x的变化，每一个版本的变化，使用的组件都有大的改变。Spring Cloud netflix中的zuul， ribbon， hystrix都基本上算是废了。

     zuul改用spring cloud gateway， Hystrix 直接改用Spring Cloud Circuit Breaker + Resilience4J，Ribbon改用 Spring Cloud Load Balancer.

     本次升级到spring cloud Hoxton.SR12，spring boot版本升级到2.3.12.RELEASE，仍然使用eureka server，服务发现服务的升级很简单，只需要更改spring cloud和spring boot的版本号即可。

   这里我弃用tomcat，改用undertow

 

 

   增加spring security：

 

 

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@EnableWebSecurity
public class WebSecurityConfigurer extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.formLogin().defaultSuccessUrl("/")
            .and().httpBasic()
            .and()
            .authorizeRequests()
            .antMatchers("/login").permitAll()
            .anyRequest()
            .authenticated()
            .and().headers().frameOptions().disable()
            .and().csrf().disable();
    }
}

   .httpBasic()不能少，不然访问不了注册中心，服务无法注册。

 

 application.yml配置文件增加spring security的用户名密码：

    

server:
  port: 8761
spring:
  application:
    name: service-discovery-server
  security:
    basic:
      enabled: true
    user:
      name: admin
      password: 123456

   eureka-server配置：

   

eureka:
  server:
    enable-self-preservation: false
    eviction-interval-timer-in-ms: 4000
  instance:
    prefer-ip-address: true
    hostname: 127.0.0.1
  client:
    # 如果是集群，下面两个改为true
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@127.0.0.1:${server.port}/eureka/
