这个错误卡了俩天没有解决掉，网上看了看各种各样的方法，有的说的权限问题，需要修改权限，有的说是版本问题，但是后面看了各种各样的玩意还是没解决掉

这是我的配置文件 

代码语言：javascript复制
spring:
  datasource:
    username: root
    data-password: 123456
    url: jdbc:mysql://192.168.231.144:3306/gulimall_pms?useSSL=true&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
mybatis-plus:
  mapper-locations: classpath:/mapper/**/*.xml
  global-config:
    db-config:
      id-type: auto

最后突发奇，直接粘贴下人人网的快速的配置文件进行修改，以为我人人网的能跑。 

代码语言：javascript复制
spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      driver-class-name: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://192.168.231.144:3306/gulimall_pms-?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai

      password: 123456

      max-pool-prepared-statement-per-connection-size: 20

发现可以跑了。 

什么！！！！！！你问我为什么能跑了？还没心情搞。能跑就完了，可以进行下一步了 

data-password: 123456 呃找到了，写成了这玩意

今日分享 通过标签<dependencyManagement>: 如： <dependencyManagement>         <dependencies>            <dependency>               <groupId>org.springframework.boot</groupId>               <artifactId>spring-boot-dependencies</artifactId>               <version>1.4.1.RELEASE</version>               <type>pom</type>               <scope>import</scope>            </dependency>         </dependencies>     </dependencyManagement> 注意：上述的type=pom意味着我们可以将所有的jar包打包成一个pom，然后我们依赖了pom，即可以下载下来所有依赖的jar包;scope=import代表从其它的pom中导入dependency的配置；

maven 编程算法 jar spring
