SpringCloud用Zookeeper搭建配置中心的方法

<!-- 提供zookeeper整合的包 --><dependency>  <groupId>org.springframework.cloud</groupId>  <artifactId>spring-cloud-starter-zookeeper-config</artifactId></dependency><!-- springboot 提供监听的 --><dependency>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-starter-actuator</artifactId></dependency>

#指定zookeeper的地址,多个用逗号拼接spring.cloud.zookeeper.connect-string=192.168.100.0:2181#指定springcloud 读取zookeeper路径的开始位置spring.cloud.zookeeper.config.root=springcloud#开始zk的配置spring.cloud.zookeeper.config.enabled=true#zk会在你指定的根目录下寻找以这个项目名命名的目录下的配置spring.application.name=service_config

//不能动态更新值,需要重启项目@Value("${com.xxx.username}") public String username ;

//可以动态修改值,不需要重启@ConfigurationProperties(prefix = "com.xxx")public class UserInfo {  public String username ;  public String getUsername() {    return username;  }  public void setUsername(String username) {    this.username = username;  }}

@SpringBootApplication//支持多个配置类@EnableConfigurationProperties({xxx.class,abc.class})public class ServiceConfigApplication {  public static void main(String[] args) {    SpringApplication.run(ServiceConfigApplication.class, args);  }}

spring.cloud.zookeeper.config.root=xxxx ;spring.application.name=abc

@value(${com.gabo.username})
