Spring boot2.x 集成 druid-spring-boot-starter 报错

编程知识更新时间:2023-04-05 03:37:07

错误如下：

java.lang.IllegalStateException: Error processing condition on org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration$PooledDataSourceConfiguration
....
Caused by: java.lang.IllegalStateException: Failed to introspect Class [com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure] from ClassLoader [sun.misc.Launcher$AppClassLoader@58644d46]
....
Caused by: java.lang.NoClassDefFoundError: org/springframework/boot/autoconfigure/jdbc/metadata/DataSourcePoolMetadataProvider
....
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.autoconfigure.jdbc.metadata.DataSourcePoolMetadataProvider

问题所在：
你的durid-spring-boot-starter中自动配置类
com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure依赖的DataSourcePoolMetadataProvider 以及在spring-boot-autoconfigure项目2.0以后删除掉了！

解决：
druid当然也升级了自己的 starter 了啊！你只需要升级到 1.1.10 即可！

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10 </version>
        </dependency>
