控制台出现Failed to bind properties under ‘spring.datasource‘ to javax.sql.DataSource

网上查了下，没有找打相关的报错解决办法，所以在解决问题后，整理到网上，帮助有需要的朋友。

springboot整合druid时，引入了druid的数据源，在配置文件application.yml中配置了相关配置

    initialSize: 5minIdle: 5maxActive: 20maxWait: 60000timeBetweenEvictionRunsMillis: 60000minEvictableIdleTimeMillis: 300000validationQuery: SELECT 1 FROM DUALtestWhileIdle: truetestOnBorrow: falsetestOnReturn: falsepoolPreparedStatements: true
#   配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙filters: stat,wall,log4jmaxPoolPreparedStatementPerConnectionSize: 20useGlobalDataSourceStat: trueconnectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

也作了相关配置 DruidConfig.class

@Configuration
public class DruidConfig {@ConfigurationProperties(prefix = "spring.datasource")@Beanpublic DataSource druid() {return new DruidDataSource();}// 配置Druid的监控// 1、配置一个管理后台的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", "");// 默认就是允许所有访问initParams.put("deny", "10.18.172.124");bean.setInitParameters(initParams);return bean;}// 2、配置一个web监控的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;}
}

但是在启动时报错：

APPLICATION FAILED TO START

Description:

控制台出现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

根据报错提示在配置文件的24行，查看配置文件，该行代码是 filters: stat,wall,log4j

看报错原因Reason: org.apache.log4j.Logger，于是猜想少了log4j的相关依赖，在pom中引入相关依赖

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