我正在开发一个新的Spring Boot应用程序(我的第一个实际应用程序),并且使用IntelliJ 2018.1.1和Maven,我的Maven配置如下所示:
的pom.xml
4.0.0 com.mygroupid myartifactid 0.0.1-SNAPSHOT jar first-spring-boot-application Spring Boot org.springframework.boot spring-boot-starter-parent 2.0.1.RELEASE UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-data-jpa org.springframework.boot spring-boot-starter-thymeleaf org.springframework.boot spring-boot-starter-web org.postgresql postgresql org.projectlombok lombok true org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-maven-plugin
应用程序使用h2数据库很好,但我需要使用Postgres,所以我添加了它的依赖项,并开始配置它.
application.properties
############### # POSTGRES ############### spring.datasource.platform=postgres spring.datasource.name=mydatasource spring.datasource.driverClassName=org.postgresql.Driver spring.datasource.url=jdbc:postgresql://localhost:5432/mydatabase spring.datasource.username=justauser spring.datasource.password=justapassword ############### # H2 ############### # spring.h2.console.enabled=true # spring.datasource.name=sp2ndsem ############### # OUTPUT ############### spring.jpa.show-sql=true ############### # WEB ############### spring.resources.static-locatiOns=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
错误
现在,在启动应用程序时,我收到一个错误,这或多或少意味着没有安装Postgres驱动程序.
IntelliJ在application.properties中用红色标记驱动程序名称:
spring.datasource.driverClassName=org.postgresql.Driver
输出显示了一些我真的无法弄清楚原因:

引起:java.sql.SQLFeatureNotSupportedException:Die Methode org.postgresql.jdbc.PgConnection.createClob()ist noch nicht implementiert.在org.postgresql.Driver.notImplemented(Driver.java:669)〜[postgresql-42.1.4.jar:42.1.4] org.postgresql.jdbc.PgConnection.createClob(PgConnection.java:1246)〜[postgresql- 42.1.4.jar:42.1.4] ...省略了44个常用帧
英文:org.postgresql.jdbc.PgConnection.createClob()未实现
我究竟做错了什么?
添加这些行application.properties
,它应该工作.
# Disable feature detection by this undocumented parameter. Check the org.hibernate.engine.jdbc.internal.JdbcServiceImpl.configure method for more details. spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false # Because detection is disabled you have to set correct dialect by hand. spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect
