1 pom.xml
<?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</groupId> <artifactId>Spring-Cloud-Config-Client</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>Spring-Cloud-Config-Client</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.5.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> <spring-cloud.version>Finchley.SR1</spring-cloud.version> </properties> <dependencies> <!-- <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> --> <dependency> 用这个包 不要用上面的否则启动报错 <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2 启动类
@SpringBootApplication @EnableDiscoveryClient public class SpringCloudConfigClientApplication { public static void main(String[] args) { SpringApplication.run(SpringCloudConfigClientApplication.class, args); } }
3 配置文件、
application.properties
server.port=7023 spring.application.name=test eureka.client.service-url.defaultZone=http://localhost:8080/eureka/
在resources文件夹下新建bootstrap.properties文件
spring.cloud.config.uri=http://localhost:7066
spring.cloud.config.name=test
spring.cloud.config.profile=dev
#spring.cloud.config.discovery.enabled=true //这个暂时没调试通,先通过uri的方式吧 #spring.cloud.config.discovery.service-id=CONFIG-SERVER #spring.cloud.config.label=master
配置仓库中的application.properties为所有服务的公共配置,
config lient 首先会查找application下的配置然后在找项目下的配置,如果application和项目下都有相同的配置,则项目配置会覆盖application下的配置
4 编写测试类
@RestController public class TestController { @Value("${version}") private String version; @Value("${all.data.url}") private String dataUrl; @GetMapping("/") public String getMessage() { return version+dataUrl; } }
5 启动项目访问
test-dev 和 application-dev
成功!
