<h3 dir="auto">Which version of ShardingSphere did you use?</h3>
<p dir="auto">使用 sharding-jdbc-spring-boot-starter v4.1.1</p>
<h3 dir="auto">Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?</h3>
<p dir="auto">使用 ShardingSphere-JDBC</p>
<h3 dir="auto">Expected behavior</h3>
<h3 dir="auto">Actual behavior</h3>
<h3 dir="auto">Reason analyze (If you can)</h3>
<p dir="auto">原因是表的字段名为 key<br>
如果将字段名改为 test_key 将正常运行</p>
