Question

我将项目从sts迁移到intellij，但是intllij无法使用application.properties-> spring.datasource.url更新连接数据库，

控制台日志：

2019-06-28 15:52:27.997  INFO 78161 --- [ost-startStop-1] j.LocalContainerEntityManagerFactoryBean : Building JPA container EntityManagerFactory for persistence unit 'default'

但是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

我清除了Intellij的缓存，但无法正常工作。

Answer 1

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

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

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

有关更多信息和其他可能的解决方案，请参见：After Spring Boot 2.0 migration: jdbcUrl is required with driverClassName

Intellij不更新spring.datasource.url
