Mybatis plus報錯：Error creating bean with name 'sqlSessionFactory'

簡介
導致"sqlSessionFactory"建立失敗的情況有很多種，我遇到的應該是比較少見的一種吧
在Springboot 整合加入 mybatis-plus,啟動報錯資訊如下：

排查問題
注意到 com/baomidou/mybatisplus/autoconfigure/MybatisPlusAutoConfiguration.class， 於是找到這個類斷點除錯，發現數據源不是mysql，而是hive:
因為之間接入過Hive,所以曾經注入過hive的資料來源:
而此時我的mysql資料來源配置檔案如下：
#mapper plus 設定 mybatis-plus.mapper-locations=classpath*:mapper/*.xml #實體掃描，多個package用逗號或者分號分隔 mybatis-plus.typeAliasesPackage=com.liwei.demo.** #spring自動配置資料來源 spring.datasource.driverClassName=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test?serverTimezone=Asia/Shanghai&characterEncoding=utf8&useUnicode=true&useSSL=false&zeroDateTimeBehavior=convertToNull spring.datasource.username=root spring.datasource.password=123456
解決方式
知道了原因，問題有了方向解決，我們採用手動建立，自己構建SqlSessionFactory：
修改配置
#自定義資料來源配置: spring.datasource.db1.driverClassName=com.mysql.jdbc.Driver spring.datasource.db1.url=jdbc:mysql://127.0.0.1:3306/test?serverTimezone=Asia/Shanghai&characterEncoding=utf8&useUnicode=true&useSSL=false&zeroDateTimeBehavior=convertToNull spring.datasource.db1.username=root spring.datasource.db1.password=123456
DBconfig 配置類配置
@Configuration
public class DBConfig {
//使用自定義的資料來源配置
@Bean(name = "dataSource")
@ConfigurationProperties(prefix = "spring.datasource.db1")
public DataSource dataSource() {
return DruidDataSourceBuilder.create().build();
}
//註冊資料來源事務處理器
@Bean
public DataSourceTransactionManager transactionManager(@Qualifier("dataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource());
}
//注入SqlSessionFactory
@Bean
public SqlSessionFactory sqlSessionFactory(@Qualifier("dataSource") DataSource dataSource) throws Exception {
final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
sessionFactory.setDataSource(dataSource);
return sessionFactory.getObject();
}
}
啟動成功。
