SpringCloud ConfigServer如何读取本地文件 ，以及如何在ConfigClient中使用

1.首先要创建springcloud_config工程。pom文件如下：

 

<?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>

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

<scope>test</scope>

</dependency>

 

<dependency>

<build>

<plugins>

<plugin>

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

</plugin>

</plugins>

</build></project>

 

2.在入口类注册@EnableConfigServer @EnableEurekaClient

(1)并创建application.yml 把这个工程暴露到eruka中

端口号必须默认为8888 ，原因正在查找中

eureka:

client:

serviceUrl:

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

server:

port: 8888

spring:

application:

name: service-config

(2)并且配置application.properties文件

#设置配置文件在本地

spring.profiles.active=native

#设置配置文件的目录

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

 

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

内容：

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中增加

<dependency>

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

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

</dependency>

2.在application.yml设置

 

spring:

application:

name: service-producer-08

#这两个文件读取顺序是application.yml>application.properties，故application.properties文件会#覆盖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中设置config服务

(需要注意的是，spring.application.name为文件service-producer-08-dev.properties -dev前的所有字段否则会报错 ，config服务设置必须在application.properties文件中，否则会报错)

spring.application.name=service-producer-08

spring.cloud.config.profile=dev

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

这样的话就会成功读取到本地配置文件

发散：在configserver工程对应的本地文件夹中设置多个 xxxx-dev.properties文件,供多个工程使用

或者设置（xxxx-###.properties

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

）

一个工程对应多个配置文件
