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: 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,log4j
    
        maxPoolPreparedStatementPerConnectionSize: 20
    
        useGlobalDataSourceStat: true
    
        connectionProperties: 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")
    
    	@Bean
    
    	public DataSource druid() {
    
    		return new DruidDataSource();
    
    	}
    
     
    
    	// 配置Druid的监控
    
    	// 1、配置一个管理后台的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
    
    	@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;
    
    	}
    
    }

但是在启动时报错：

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
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

<dependency>
    
    		    <groupId>log4j</groupId>
    
    		    <artifactId>log4j</artifactId>
    
    		    <version>1.2.17</version>
    
    		</dependency>

再次启动，成功！
