Spring Cloud Config configuration center server configuration

Server configuration

Git the URI placeholder

In the previous example, we configured the configuration address spring.cloud.config.name configuration center server configuration through spring.cloud.config.uri the name of the profile, spring.cloud.config.profile configured with an address corresponding environment

server:
  port: 8102
spring:
  application:
    name: config-client-1
  cloud:
    config:
      label: master
      uri: http://localhost:8101
      # 此处配置了配置文件的名称
      name: client-config
      profile: dev
复制代码

Pattern matching and a plurality of repositories

On the application name and the profile, Spring Cloud Server also supports more complex configuration mode, you can use wildcards {application} / {profile} rule matching names, separated by commas.

example:

spring:
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/chendom/SpringCloudConfig.git
          username: xx
          password: xx
          #配置搜索路径
          search-paths: config
          repos:
              simple: https://gitee.com/chendom/simple
              special:
                pattern: special*/dev*,*special*/dev*
                uri: https://gitee.com/chendom/SpringCloudConfig-special
               local:
                pattern: local*
                uri: /Users/chendom/test/SpringCloudConfig
复制代码

Search Path

Search path placeholder

spring:
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/chendom/SpringCloudConfig.git
          username: xx
          password: xx
          #配置搜索路径
          search-paths: config,config*
复制代码

search-paths: config, config * refers to the config path is the path prefix search all configuration files are config or

spring:
  cloud:
    config:
      server:
        git:
          uri: https://gitee.com/chendom/SpringCloudConfig.git
          username: xx
          password: xx
          #配置搜索路径
          search-paths: *{application}*
           #表示合法的将远程仓库拷贝到本地
          clone-on-start: true
复制代码

clone-on-start: true indicates legal copy of the repository is remote to the local cache, to match the different items, search-path needs to be configured to * {application} *, ** must, or use '{application}'

            <artifactId>spring-cloud-config-server</artifactId>

Profiles

 server:
  port: 8103

spring:
  cloud:
    config:
      server:
        jdbc:
          sql: SELECT `KEY`, `VALUE` FROM PROPERTIES WHERE application =? AND profile =? AND lable =?
      label: master
    refresh:
      extra-refreshable: none
  profiles:
    #这里需要配置成是jdbc
    active: jdbc
  application:
    name: config-server-db
  ## 数据配置
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/config_db?useUnicode=true&characterEncoding=UTF-8
    username: root
    password: root@123
    driver-class-name: com.mysql.jdbc.Driver
复制代码

And the client is still the same as the previous example

server:
  port: 8104
spring:
  application:
    name: config-client-db
  cloud:
    config:
      label: master
      uri: http://localhost:8103
      # 此处配置了配置文件的名称
      name: client-config
      profile: test

# 设置打印的日志级别
logging:
  level:
    root: debug
复制代码

---

 @RestController
public class ConfigClientController {

@Value("${springcloud.configserver}")
public String value;
@RequestMapping("/getValue")
public String getValue(){
    return value;
}
}
复制代码

Results 8104 / getValue obtained as shown below: Request localhost:

Spring Cloud Config related to the use of skills

spring:
    cloud:
      config:
        allowOverride:true
        overrideNone: true
        overrideSystemProperties: false
复制代码

• allowOverride: identification overrideSystemProperties property is enabled. The default is true, is set to false

• overrideNone: When allowOverride is true, overrideNone set to true, the external configuration of a lower priority, and the properties of the source can not override any existing default is false

• overrideSystemProperties: Identifies the old configuration is to cover the washing property, the default is true.
