Failed to bind properties under 'spring.datasource' to javax.sql.DataSource

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: 5
minIdle: 5
maxActive: 20
maxWait: 60000
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 1 FROM DUAL
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
# 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
filters: stat,wall,log4j
maxPoolPreparedStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: 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")
@Bean
public DataSource druid() {
return new DruidDataSource();
}

// 配置Druid的監控
// 1、配置一個管理后台的Servlet
@Bean
public 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
@Bean
public 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:

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，於是猜想少了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！
