Spring Boot2中Spring Security导致Eureka注册失败

将Spring Boot升级到2.0，Spring Cloud升级到Finchley.M8时，Eureka注册就报错了

Eureka Server配置：

server.port=9011
spring.application.name=eureka-server 

spring.security.user.name=username
spring.security.user.password=pass

eureka.instance.hostname=localhost 
eureka.client.register-with-eureka=false 
eureka.client.fetch-registry=false 
eureka.client.service-url.defaultZone=http://username:pass@localhost:9011/eureka/

Eureka Client配置：

server.port=8088
spring.application.name=eureka-client 

spring.security.basic.enabled=true 
spring.security.user.name=username
spring.security.user.password=pass

eureka.instance.hostname=localhost 
eureka.client.service-url.defaultZone=http://username:pass@localhost:9011/eureka/

错误信息如下：

去掉Spring Security后问题解决，可以知道问题是Spring Security引起的

CSRF保护默认是开启的，可以禁用掉即可

解决方案如下：

@EnableWebSecurity
static class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
    }
}
