spring-boot 整合druid 启动报错 Failed to bind properties under spring.datasource to javax.sql.DataSource

spring-boot 整合druid 启动报错：

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

 

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。

 

mybatis.type-aliases-package=com.neo.model

spring.datasource.url=jdbc:mysql://localhost:3306/springboot?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver


# JPA 配置
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

# mybatis 配置
mybatis.config-location=classpath:mybatis/mybatis-config.xml
mybatis.mapper-locations=classpath:mybatis/mapper/*.xml


# 修改数据源
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.druid.initial-size=5  
spring.datasource.druid.min-idle=5  
spring.datasource.druid.max-active=20  
spring.datasource.druid.max-wait=60000  
spring.datasource.druid.time-between-eviction-runs-millis=60000  
spring.datasource.druid.min-evictable-idle-time-millis=300000  
spring.datasource.druid.validation-query=SELECT 1 FROM DUAL  
spring.datasource.druid.test-while-idle=true  
spring.datasource.druid.test-on-borrow=false  
spring.datasource.druid.test-on-return=false  
spring.datasource.druid.pool-prepared-statements=true  
spring.datasource.druid.max-pool-prepared-statement-per-connection-size=20  
spring.datasource.druid.filters=stat,wall,log4j  



## druid 监控
spring.datasource.druid.web-stat-filter.enabled=true
spring.datasource.druid.web-stat-filter.url-pattern=/*
spring.datasource.druid.web-stat-filter.exclusions=*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*

## druid 监控页面
spring.datasource.druid.stat-view-servlet.enabled=true
spring.datasource.druid.stat-view-servlet.url-pattern=/druid/*
spring.datasource.druid.stat-view-servlet.login-username=druid
spring.datasource.druid.stat-view-servlet.login-password=druid123

这里配置了：spring.datasource.druid.filters=stat,wall,log4j 

log4j 没有导入依赖导致报错。

解决：引入依赖

		
		    log4j
		    log4j
		    1.2.17
		

 

每天努力一点，每天都在进步。
