defaultZone: http://${spring.security.user.name}:${spring.security.user.password}@${eureka.instance.hostname}:${server.port}/eureka/注意入口类添加@EnableEurekaServer注解↓
package cn.beeson.eurekaserverdemo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerDemoApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerDemoApplication.class, args);
}
}在配置文件里关闭csrf，不然spring security会阻止其他服务向Eureka注册：
package cn.beeson.eurekaserverdemo.conf;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.web.SecurityFilterChain;
import static org.springframework.security.config.Customizer.withDefaults;
@EnableWebSecurity
@Configuration
public class WebSecurityConfig2 {
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
// 关闭csrf，确保其他服务可以注册
http.csrf().disable();
http.authorizeHttpRequests((authz) -> authz
.anyRequest().authenticated()
).httpBasic(withDefaults());
return http.build();
}
}配置完成，启动服务，并访问http://localhost:9000，出现如下页面即成功：
