自己的一个demo源码

eureka整合账号密码的功能

添加配置而且defaultZone的配置不同

server.port=8761
spring.profiles.active=master
spring.application.name=spring-cloud-eureka
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

security.basic.enabled=true
security.user.name=yinjihuan
security.user.password=123456
eureka.client.serviceUrl.defaultZone=http://yinjihuan:123456@localhost:8761/eureka/

添加jar包依赖

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>

2.x 版本权限配置

application配置不同，需要添加前缀spring
eureka的server端需要关闭CSRD保护

2.0 版配置 server端

spring.security.basic.enabled=true
spring.security.user.name=huangzs
spring.security.user.password=123456

eureka.client.serviceUrl.defaultZone=http://huangzs:123456@localhost:8762/eureka/

2.X CSRF保护默认是开启的，可以禁用掉即可

通过配置server端的代码

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