druid和druid-spring-boot-starter 的区别与报错Cannot resolve configuration property ‘spring.datasource.xxx解决

druid官方文档:https://github.com/alibaba/druidhttps://github.com/alibaba/druid/wikidruidmaven仓库https://mvnrepository.com/artifact/com.alibaba/druid一、druid和druid-spring-boot-starter区别分析参考文章:https://www.cnblogs.com/dxiaodang/p/14571590.html主要原因还是要不要手动写配置类,springboot的使用auto帮我们封装好了属性值描述如下:作用是一样的,都是连接池提供连接,里

Android在构建提示“Could not resolve all files for configuration ‘:app:debugRuntimeClasspath‘.”

今天在添加MQTT依赖库的时候,在构建时提示一下错误:Causedby:org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException:Couldnotresolveallfilesforconfiguration':app:debugRuntimeClasspath'.后面根据错误的提示发现可能和工程中build.gradle(:app)里面添加的这一句有关系:implementation'com.android.support:support-v4:4.4.1

import org.apache.hadoop.conf.Configuration无法import;The import org.apache cannot be resolved

查找网上许多方法都没用,最后自己从包处解决importorg.apache.hadoop.conf.Configuration;importorg.apache.hadoop.fs.FileSystem;importorg.apache.hadoop.fs.Path;importorg.apache.hadoop.io.IOUtils;出现上述都无法import的情况报错显示:Theimportorg.apachecannotberesolved分析得出无法找到对应的包,而看报错先看第一个报错org.apache.hadoop.conf.Configuration这个的包是hadoop-com
