Question

我将我的项目从 sts 迁移到 intellij，但是 intllij 没有使用 application.properties -> spring.datasource.url 更新连接数据库，不起作用

但在我的代码中是这样的:

spring.datasource.url=jdbc:postgresql://localhost:5432/newdb
spring.datasource.username=username
spring.datasource.password=pass
spring.datasource.tomcat.max-active=40
spring.datasource.tomcat.max-idle=40
spring.datasource.tomcat.min-idle=40
jpa.dialect=org.hibernate.dialect.PostgreSQLDialect
spring.datasource.driver-class-name=org.postgresql.Driver
org.springframework.boot = spring-boot-starter-jersey

# Hikari will use the above plus the following to setup connection pooling
spring.datasource.hikari.minimumIdle=5
spring.datasource.hikari.maximumPoolSize=20
spring.datasource.hikari.idleTimeout=30000
spring.datasource.hikari.poolName=MatdmJPAHikariCP
spring.datasource.hikari.maxLifetime=2000000
spring.datasource.hikari.connectionTimeout=30000

我清理了 Intellij 的缓存，但它不起作用。

Answer 1

对于 Hikari 连接池，url 属性是 jdbc-url，而不是 url。所以改变一下

spring.datasource.url=jdbc:postgresql://localhost:5432/newdb至

spring.datasource.jdbc-url=jdbc:postgresql://localhost:5432/newdb
