SpringBoot-Admin实现微服务监控+健康检查+钉钉告警

基于SpringCloud微服务平台，进行服务实例监控及健康检查，注册中心为eureka，SpringBoot提供了很好的组件SpringBoot Admin，2.X版本直接可以配置钉钉机器人告警。

效果：可以实现eureka注册的实例上线、下线触发钉钉告警。监控我们的服务实例健康检查。

	public static void main(String[] args) {
		SpringApplication.run(AdminServerApplication.class, args);
	}
}

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

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