schema.sql: 创建数据库表的SQL语句
DROP TABLE IF EXISTS licenses; CREATE TABLE licenses ( license_id VARCHAR(100) PRIMARY KEY NOT NULL, organization_id TEXT NOT NULL, license_type TEXT NOT NULL, product_name TEXT NOT NULL, license_max INT NOT NULL, license_allocated INT, comment VARCHAR(100)); INSERT INTO licenses (license_id, organization_id, license_type, product_name, license_max, license_allocated) VALUES ('f3831f8c-c338-4ebe-a82a-e2fc1d1ff78a', 'e254f8c-c442-4ebe-a82a-e2fc1d1ff78a', 'user','customer-crm-co', 100,5); INSERT INTO licenses (license_id, organization_id, license_type, product_name, license_max, license_allocated) VALUES ('t9876f8c-c338-4abc-zf6a-ttt1', 'e254f8c-c442-4ebe-a82a-e2fc1d1ff78a', 'user','suitability-plus', 200,189); INSERT INTO licenses (license_id, organization_id, license_type, product_name, license_max, license_allocated) VALUES ('38777179-7094-4200-9d61-edb101c6ea84', '442adb6e-fa58-47f3-9ca2-ed1fecdfe86c', 'user','HR-PowerSuite', 100,4); INSERT INTO licenses (license_id, organization_id, license_type, product_name, license_max, license_allocated) VALUES ('08dbe05-606e-4dad-9d33-90ef10e334f9', '442adb6e-fa58-47f3-9ca2-ed1fecdfe86c', 'core-prod','WildCat Application Gateway', 16,16);
访问本地的configuration server暴露的8888端口,调用default环境的配置文件
在Git repos上的配置文件的命名规则是要跟bootstrap.yml中的配置匹配:
${spring.application.name}-${spring.profiles.active}.yml
创建controller
package com.cloudlearning.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.cloudlearning.config.ServiceConfig; import org.springframework.web.bind.annotation.GetMapping; @RestController public class LicenseServiceController { @Autowired private ServiceConfig serviceConfig; @GetMapping(value="/licensingservice") public String getExampleProperty() { return serviceConfig.getExampleProperty(); } }
创建service
package com.cloudlearning.config; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; @Component public class ServiceConfig{ @Value("${example.property}") private String exampleProperty; public String getExampleProperty(){ return exampleProperty; } }
浏览器访问controller中定义的URI:/licensingservice,将返回在Git上default环境springcloud-03-licensingservice.yml中的example.property的值"I AM IN THE DEFAULT"
测试:
1. 启动configuration server:springcloud-02-confsrv
从log文件中可以看到对应调用的springcloud-03-licensingservice.yml
2018-04-18 11:48:50.639 INFO 4608 --- [nio-8888-exec-3] o.s.c.c.s.e.NativeEnvironmentRepository : Adding property source: file:/C:/Users/Administrator/AppData/Local/Temp/config-repo-8073690710026718888/licensingservice/springcloud-03-licensingservice.yml
2. 启动licensingservice: springcloud-03-licensingservice
