我正在尝试将 spring-boot 连接到我的 postgresql 数据库。Spring 正在尝试连接 mysql。在我的 pom 或 application.properties 中没有任何关于 mysql 的内容！我尝试了 Eclipse 和 inteliji 都给出了相同的错误。
这是我的 application.properties
spring.datasource.url=jdbc:postgresql:://localhost:5432/stat
spring.datasource.username=${SPRING_DATASOURCE_USERNAME}
spring.datasource.password=${SPRING_DATASOURCE_PASSWORD}
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.database-platform=org.postgresql.Driver
#spring.jpa.hibernate.ddl-auto=${SPRING_JPA_HIBERNATE_DDL-AUTO}
spring.jpa.hibernate.ddl-auto=create
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
spring.jpa.hibernate.s=true
spring.jpa.show-sql=true
spring.jackson.serialization.fail-on-empty-beans=false
spring.datasource.hikari.connectionTimeout=20000
这是我的 pom.xml
