Druid是阿里巴巴開發的一個連接池,他提供了一個高效、功能強大、可擴展性好的數據庫連接池,區別于hikari。如果選擇高性能可以選hikari,如果要功能多就選,druid。
首先pom引入依賴

然后在項目config下配置參數

import java.util.HashMap; @Configuration public class DruidConfig implements WebMvcConfigurer { @Bean @ConfigurationProperties (prefix = "spring.datasource" ) public DataSource druidDataSource(){ return new DruidDataSource(); } //后臺監控 @Bean public ServletRegistrationBean statViewServlet(){ ServletRegistrationBean<StatViewServlet> statViewServlet = new ServletRegistrationBean<>( new StatViewServlet(), "/druid/*" ); //配置后臺登錄用戶名密碼 HashMap<String, String> objectObjectHashMap = new HashMap<>(); //用戶名參數密碼不能改變,系統配置 objectObjectHashMap.put( "loginUsername" , "admin" ); objectObjectHashMap.put( "loginPassword" , "admin" ); //允許誰可以訪問 為空時所有人可以訪問 例如:objectObjectHashMap.put("allow","localhost"); 代表只能自己訪問 objectObjectHashMap.put( "allow" , "" ); //禁止誰訪問 objectObjectHashMap.put("name","192.168.0.1"); statViewServlet.setInitParameters(objectObjectHashMap); return statViewServlet; } } |
然后就可以在后臺輸入 項目地址/druid進行登錄訪問
