使用 Spring Boot Admin 管理 Spring Boot 应用

client 使用了主机名注册

client actuator使用了hostname进行注册时无法绑定到Spring Boot Admin，可设置prefer-ip属性为true即可解决。

spring:
  boot:
    admin:
      client:
        url: http://localhost:12345
        instance:
          prefer-ip: true

设置邮件提醒

Spring Boot Admin Server中设置client下线通知

• 添加spring-boot-starter-mail依赖

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

• 设置admin发/收件人

spring:
  boot:
    admin:
      notify:
        mail:
          from: ${spring.mail.username}
          to: receiver@163.com
  mail:
    host: smtp.163.com
    username: username@163.com
    password: # your own password

535 Error: authentication failed

• 网易邮箱有没有开启授权码，若开启则password为授权码
• username需是完整的登录名，如：15317832520@163.com

553 Mail from must equal authorized user

必须设置spring.boot.admin.notify.mail.from属性，默认是Spring Boot Admin <noreply@localhost>。

spring:
  boot:
    admin:
      notify:
        mail:
          from: ${spring.mail.username}
  mail:
    username: 15317832520@163.com

Spring Boot Admin添加登录页面

• 添加spring-boot-starter-security依赖

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

• 设置用户名密码

spring:
  security:
    user:
      name: admin
      password: admin123

• 配置Spring Boot Admin登录页面

@Configuration
public class SecuritySecureConfig extends WebSecurityConfigurerAdapter {

    private final String adminContextPath;

    public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
        this.adminContextPath = adminServerProperties.getContextPath();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // @formatter:off
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter( "redirectTo" );

        http.authorizeRequests()
                .antMatchers( adminContextPath + "/assets/**" ).permitAll()
                .antMatchers( adminContextPath + "/login" ).permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage( adminContextPath + "/login" ).successHandler( successHandler ).and()
                .logout().logoutUrl( adminContextPath + "/logout" ).and()
                .httpBasic().and()
                .csrf().disable();
        // @formatter:on
    }
}
