bootstrap.yml 未在 Spring Boot 2 中加载

Question

I'm experiencing a problem when starting a spring boot client application that needs to connect to the configuration server. The bootstrap.yml file is being ignored

Configuration Server - This works!

server:
  port: 8888  
spring:
  application:
    name: configserver
  cloud:
    config:
      server:
        git:
          uri:https://xxxxx@bitbucket.org/eco/properties.git

bootstrap.yml - Config Client - Not working!

spring:
  application:
    name: api
  cloud:
    config:
      uri: http://localhost:8888

The file bootstrap.yml is being ignored when starting the application .

    }
}

Why is the bootstrap.yml being ignored?

Answer 1

您需要为 spring cloud starter 添加依赖项。

Answer 2

Add this dependency in spring boot config client:

<dependency>
 <groupId>org.springframework.cloud</groupId>
 <artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

Answer 3

this is the dependency you must add

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server</artifactId>
    </dependency>

Answer 4

You need to specify a config name and it must match the config file name on the configuration service.

spring:
    cloud:
       config:
          name: myService    # myService.yml or myService-[profile].yml( if you have a profile activated).
           uri: http://localhost:8888

Answer 5

If you defined a spring.config.location it will override all paths to the configurations files including the path to bootstrap.yml so you have to change spring.config.location to spring.config.additional-location .

So when you launch your app you'll have to add -Dspring.config.additional-location=/path/to/application.yml .

Answer 6

Application will use bootstrap.yml in case when it uses some spring-cloud dependencies. That can be cloud discovery client

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>

or cloud config client

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-client</artifactId>
    </dependency>

Answer 7

I had the same problem. The pom.xml i used specified the files it includes from src/main/resources. So i also had to add the bootstrap.properties here:

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>application.properties</include>
                    <include>bootstrap.properties</include>
                </includes>
            </resource>
        </resources>
...</build>

Answer 8

In my case I using STS4 and the produced POM file by default doesn't work and I hade the same problem like you, but after I changed a little bit in my POM file, everything is working and finally I found something like "Fetching config from server at" in my console. The changes in my POM were as follows:

1. Change the spring boot version to 2.2.6.RELEASE.
2. Change the spring cloud version to Hoxton.SR6 Or Hoxton.SR4 (and I believe any Hoxton version will work).

After I applied the previous changes, My POM file looks like:

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <!-- <version>2.4.0</version> -->
        <version>2.2.6.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>
    <groupId>net.kha.microservices</groupId>
    <artifactId>limits-service</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>limits-service</name>
    <description>Demo project for Spring Boot - Cloud</description>

    <properties>
        <java.version>1.8</java.version>
        
        <!-- <spring-cloud.version>2020.0.0-SNAPSHOT</spring-cloud.version> -->
        <!-- <spring-cloud.version>2020.0.0-M4</spring-cloud.version> -->
        
        <!--  Both are working with spring boot version 2.2.6.RELEASE 
              you should find something like "Fetching config from server at" in your console 
              each time you run the client project as spring boot app 
        -->
        <spring-cloud.version>Hoxton.SR6</spring-cloud.version>
        <!-- <spring-cloud.version>Hoxton.SR4</spring-cloud.version> -->    
    </properties>
