網上查了下，沒有找打相關的報錯解決辦法，所以在解決問題后，整理到網上，幫助有需要的朋友。

springboot整合druid時，引入了druid的數據源，在配置文件application.yml中配置了相關配置

initialSize: 5minIdle: 5maxActive: 20maxWait: 60000timeBetweenEvictionRunsMillis: 60000minEvictableIdleTimeMillis: 300000validationQuery: SELECT 1 FROM DUALtestWhileIdle: truetestOnBorrow: falsetestOnReturn: falsepoolPreparedStatements: true # 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用于防火墻filters: stat,wall,log4jmaxPoolPreparedStatementPerConnectionSize: 20useGlobalDataSourceStat: trueconnectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

也作了相關配置 DruidConfig.class

@Configuration public class DruidConfig {@ConfigurationProperties(prefix = "spring.datasource")@Beanpublic DataSource druid() {return new DruidDataSource();}// 配置Druid的監控// 1、配置一個管理后臺的Servlet@Beanpublic ServletRegistrationBean statViewServlet() {ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet(), "/druid/*");Map<String, String> initParams = new HashMap<>();initParams.put("loginUsername", "admin");initParams.put("loginPassword", "123456");initParams.put("allow", "");// 默認就是允許所有訪問initParams.put("deny", "10.18.172.124");bean.setInitParameters(initParams);return bean;}// 2、配置一個web監控的filter@Beanpublic FilterRegistrationBean webStatFilter() {FilterRegistrationBean bean = new FilterRegistrationBean();bean.setFilter(new WebStatFilter());Map<String, String> initParams = new HashMap<>();initParams.put("exclusions", "*.js,*.css,/druid/*");bean.setInitParameters(initParams);bean.setUrlPatterns(Arrays.asList("/*"));return bean;} }

但是在啟動時報錯：

---

APPLICATION FAILED TO START

---

Description:

控制臺出現Failed to bind properties under ‘spring.datasource’ to javax.sql.DataSource:

Property: spring.datasource.filters Value: stat,wall,log4j Origin: class path resource [application.yml]:24:14 Reason: org.apache.log4j.Logger

Action:

Update your application’s configuration

根據報錯提示在配置文件的24行，查看配置文件，該行代碼是 filters: stat,wall,log4j

看報錯原因Reason: org.apache.log4j.Logger，于是猜想少了log4j的相關依賴，在pom中引入相關依賴

<!-- https://mvnrepository.com/artifact/log4j/log4j --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency>

再次啟動，成功！
