spring boot 连接SQL SERVER 部署k8s docker环境后报错：Failed to configure a DataSource: ‘url‘ attribute is not

本机调试OK，但是部署DOCKER之后报错：

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured. 

 

一直以为是数据驱动JAR问题，后来验证了两点：

 

1：spring boot 2.0之后，数据库连接SQL server用：

        
            com.microsoft.sqlserver
            sqljdbc4
            4.0
        

2：如果有外部JAR打包需要配置：

2.1：拷贝JAR到src-resources-lib文件夹下

2.2：补充POM.XML下配置

        
            com
            xcwebapi
            1.1
            system
            ${project.basedir}/src/main/resources/lib/JDK_1.8_corp.openapicalls.lib.webapi.jar
        

2.3：补充加载所有JAR

        ${project.artifactId}-${project.version}
        
        
            
                org.apache.maven.plugins
                maven-war-plugin
                
                    
                        
                            src/main/resources/lib/
                            WEB-INF/lib/
                            
                                **/*.jar
                            
                        
                    
                
            

这两点验证没问题之后，部署K8 DOCKER还是报错。

最后，最后经过调试和灵感才发现。原来DOCKER环境里认的是：application.properties

而认不到：application-prd2.yml

 

重新部署后，运行正常。
