1.服务端的配置信息
application.yml
server:
port: 8888
spring:
application:
name: config-server
cloud:
config:
server:
git:
uri: https://github.com/gholly/configProperties
searchPaths: configPath
username: xxx
password: xxx
label: master
profile: master
stream:
kafka:
binder:
zk-nodes: localhost:2181
brokers: localhost:9092
bus:
enabled: true
由于2.0的改动较大，/bus/refresh全部整合到actuador里面了，所以之前1.x的management.security.enabled全部失效，不适用于2.0，
适用于2.0的配置是这样的：
management.endpoints.web.exposure.include=*
接下来2.0的坑还有一个就是management.endpoints.web.exposure.include=*不支持yml格式，会报错，
所以有了bootstrap.properties文件：
management.endpoints.web.exposure.include=*
或者：
management:
endpoints:
web:
exposure:
include: bus-refresh
gradle依赖如下：
buildscript {
ext {
springBootVersion = '2.0.0.RELEASE'
}
repositories {
mavenCentral()
maven { url "https://repo.spring.io/milestone" }
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
group = 'com.gholly.config.client'
version = '1.0-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
maven { url "https://repo.spring.io/milestone" }
}
ext {
springCloudVersion = 'Finchley.M7'
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.boot:spring-boot-starter-actuator')
compile('org.springframework.cloud:spring-cloud-starter-config')
compile('org.springframework.cloud:spring-cloud-starter-bus-kafka')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
java文件：
@EnableConfigServer
@SpringBootApplication
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class,args);
}
}运行成功后，会出现一些端点，此是与1.x不一样的地方：
2.接下来是客户端：
配置文件：
server:
port: 8008
spring:
cloud:
config:
uri: http://localhost:8888/
profile: dev
label: master
stream:
kafka:
binder:
zk-nodes: localhost:2181
brokers: localhost:9092
bus:
enabled: true
application:
name: config
bootstrap.properties文件：
management.endpoints.web.exposure.include=*
依赖：
buildscript {
ext {
springBootVersion = '2.0.0.RELEASE'
}
repositories {
mavenCentral()
maven { url "https://repo.spring.io/milestone" }
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
group = 'com.cmbchina.csc.config.client'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
mavenCentral()
maven { url "https://repo.spring.io/milestone" }
}
ext {
springCloudVersion = 'Finchley.M7'
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-web')
compile('org.springframework.cloud:spring-cloud-starter-config')
compile('org.springframework.cloud:spring-cloud-starter-bus-kafka')
testCompile('org.springframework.boot:spring-boot-starter-test')
}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
java文件：
@RestController
@RefreshScope
@SpringBootApplication
public class ClientApplication {
public static void main(String[] args) {
SpringApplication.run(ClientApplication.class,args);
}
@Value("${test}")
public String hh;
@RequestMapping("/hh")
public String test(){
return hh;
}
}3.测试阶段：
当两者运行成功之后，访问接口http://localhost:8008/hh
然后更改git上的配置文件，更改后，发现接口内容不变，然后以post方式调取localhost:8008/actuator/bus-refresh实现配置的动态刷新，虽然返回结果为空，但确实是动态刷新了
刷新后的接口：
