SpringCloud ConfigServer如何讀取本地文件 ，以及如何在ConfigClient中使用

1.首先要建立springcloud_config工程。pom文件以下：

 

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

 

<groupId>com.example.config</groupId>

<artifactId>springcloud_config</artifactId>

<version>0.0.1-SNAPSHOT</version>

<packaging>jar</packaging>

 

<name>springcloud_config</name>

<description>Demo project for Spring Boot</description>

 

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>1.5.8.RELEASE</version>

<relativePath/> <!-- lookup parent from repository -->

</parent>

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

<java.version>1.8</java.version>

</properties>

<dependencies>

</dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-test</artifactId>

<scope>test</scope>

</dependency>

 

<dependency>

<build>

<plugins>

<plugin>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

</plugins>

</build></project>

 

2.在入口類註冊@EnableConfigServer @EnableEurekaClient

(1)並建立application.yml 把這個工程暴露到eruka中

端口號必須默認爲8888 ，緣由正在查找中

eureka:

client:

serviceUrl:

defaultZone: http://admin:password123@127.0.0.1:8760/eureka/

server:

port: 8888

spring:

application:

name: service-config

(2)而且配置application.properties文件

#設置配置文件在本地

spring.profiles.active=native

#設置配置文件的目錄

spring.cloud.config.server.native.search-locations=E:/SpringCloudWorkSpace/localServiceProperties

 

(3)本地配置文件名稱爲 service-producer-08-dev.properties

內容：

test.type=test

test.url=jdbc:oracle:thin:@xxxxxxxxx:ORCL

test.class=oracle.jdbc.OracleDriver

test.user=xxxxxx

test.password=xxxx

 

 

以上，配置config service完成

 

配置config client：

1.在pom.xml中增長

<dependency>

<groupId>org.springframework.cloud</groupId>

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

</dependency>

2.在application.yml設置

 

spring:

application:

name: service-producer-08

#這兩個文件讀取順序是application.yml>application.properties，故application.properties文件會#覆蓋application.yml文件的相同配置

jpa:

generate-ddl: false

show-sql: true

hibernate:

ddl-auto: none

datasource:

driver-class-name: ${test.class}

url: ${test.url}

username: ${test.user}

password: ${test.password}

 

2.1在application.properties中設置config服務

(須要注意的是，spring.application.name爲文件service-producer-08-dev.properties -dev前的全部字段不然會報錯 ，config服務設置必須在application.properties文件中，不然會報錯)

spring.application.name=service-producer-08

spring.cloud.config.profile=dev

spring.cloud.config.uri= http://localhost:8888/

這樣的話就會成功讀取到本地配置文件

發散：在configserver工程對應的本地文件夾中設置多個 xxxx-dev.properties文件,供多個工程使用

或者設置（xxxx-###.properties

spring.cloud.config.profile=dev 修改成 spring.cloud.config.profile=###

）

一個工程對應多個配置文件
