场景描述

SpringBoot项目配置多个数据源，启动无异常，插入数据报错。

---

异常原因

SpringBoot中的application配置数据源名称变更。导致找不到数据源的url

---

解决方案

1.??版本的spring.datasource.url 和spring.datasource.driverClassName。
更改为
2.??版本的
spring.datasource.jdbc-url和spring.datasource.driver-class-name

最终有效配置

#配置jsp
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
#数据源1
spring.datasource.test1.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.test1.jdbc-url = jdbc:mysql://localhost:3306/test01?useUnicode=true&characterEncoding=utf-8
spring.datasource.test1.username = root
spring.datasource.test1.password = root
#数据源2
spring.datasource.test2.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.test2.jdbc-url = jdbc:mysql://localhost:3306/test02?useUnicode=true&characterEncoding=utf-8
spring.datasource.test2.username = root
spring.datasource.test2.password = root
