In standalone mode, the metadata is stored in the H2 memory by default, so we need to use the H2 driver to connect.
I think later versions will fix this.

> In the Java API scenario, `DriverManager` can scan the required drivers, but the Spring namespace needs to find the corresponding `Bean`, the search way is different.
```
Thank you !!!
shardingsphere5.2.1 spring-namespace error Has been solved. just only add <bean id="h2Driver" class="org.h2.Driver">
but
shardingSphere Upgrade the version to 5.3.1. use yaml+Driver instead of spring-namespace
The same code , I user yaml+Driver Encountered the same problem
I really want to cry because every example i write has error
```
## 1. dependency（5.3.1）

> In standalone mode, the metadata is stored in the H2 memory by default, so we need to use the H2 driver to connect. I think later versions will fix this.

H2 need driver but write code by JavaAPI why not need write h2 driver (example below)

In the Java API scenario, `DriverManager` can scan the required drivers, but the Spring namespace needs to find the corresponding `Bean`, the search way is different.
