使用JTDS在Spring Boot中配置HikariCP

Question

我想將連接池添加到使用Spring Boot 1.5.1製作的現有Web應用程序中。

數據源配置在application.properties做出如下：

spring.datasource.url=jdbc:jtds:sqlserver://localhost:1433;databaseName=MyDatabase;instance=SQLServer2014; 
spring.datasource.username=myuser 
spring.datasource.password=passwd 
spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver 
spring.jpa.hibernate.ddl-auto=update 

我不需要做任何進一步的配置，這就夠了。

在官方docs中，雖然顯示了參數，但在Spring Boot docs中也不太清楚。

所以，我一直在尋找那裏的解決方案（this one,this one too ...）。

我做了幾個試驗，但每次運行應用程序時，都會拋出有關HikariCP的異常。

當添加spring.datasource.type=com.zaxxer.hikari.HikariDataSource，以下異常被拋出：

所以，這是添加hikaricp我application.properties最簡單的方法？

Answer 1

您正在收到以下錯誤。

Caused by: java.lang.AbstractMethodError: null at net.sourceforge.jtds.jdbc.JtdsConnection.isValid(JtdsConnection.java:2833)

問題是net.sourceforge.jtds.jdbc.JtdsConnection沒有實現isValid所以你需要指定一個連接測試查詢，以確保isValid方法不叫。嘗試在application.properties文件中添加以下屬性。

spring.datasource.hikari.connection-test-query=SELECT 1
