testwhileIdle is true validationQuery not set

这是一个关于连接池的错误信息。它表明在连接池中,testWhileIdle 属性被设置为 true,该属性表示当连接空闲时是否需要测试连接的可用性。另外,它还提示你没有设置 validationQuery 属性,该属性指定了用于测试连接可用性的 SQL 查询语句。
为了解决这个错误,你需要设置 validationQuery 属性。你可以将其设置为一个简单的 SQL 查询语句,比如 "SELECT 1"。具体的操作取决于你使用的连接池库和其对应的配置方式。

testWhileIdle is true, validationQuery not set
testWhileIdle is true, validationQuery not set 是一个错误消息,表示在配置连接池时没有设置validationQuery检测语句。为了解决这个问题,你需要将testWhileIdle设置为false,并设置一个非空的validationQuery。此外,你还可以通过设置testOnBorrow和testOnReturn为false来提高性能,但这样可能会降低连接的有效性检测。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

testWhileidle is true,validationQuery not set
As an AI language model, I can interpret that you may be referring to a configuration setting in a database connection pool.
In this case, `testWhileIdle` is a property that specifies whether a connection should be tested for validity when it is idle in the pool. The value `true` indicates that the connection should be tested.
On the other hand, `validationQuery` is a property that specifies the SQL query to be executed to test the validity of a connection. If this property is not set, the pool may use a default validation query, which may not be suitable for your database.
Therefore, it is recommended to set a valid `validationQuery` property in your database connection pool configuration to ensure that idle connections are properly tested for validity.
