我回去编程我的旧程序
https://github.com/JonkiPro/REST-Web-Services.我已经将Spring Boot从版本15.6更新到版本2.0.0.我在编译时遇到了很多问题,但我无法处理.好吧,在编译期间,他把我扔进了控制台

我从未犯过这样的错误.我完全不知道这意味着什么.我的基地属性看起来像这样
spring:
datasource:
driver-class-name: org.postgresql.Driver
url: jdbc:postgresql:database
username: root
password: root
schema: classpath:/db/init/schema.sql
我不知道如何处理这个错误.我已经编程了很长时间,但我第一次遇到了hikari的概念.我正在使用Tomcat(在Spring Boot中)服务器和Postgresql数据库.
解决方法
我在另一个背景下遇到了同样的问题.
从 79. Data Access – Configure a Custom DataSource
从 79. Data Access – Configure a Custom DataSource
if you happen to have Hikari on the classpath,this basic setup does not work,because Hikari has no url property (but does have a jdbcUrl property)
Hikari是spring boot 2中的默认池.
所以你可以替换配置
url：jdbc：postgresql：database – > jdbc-url：jdbc：postgresql：database
或者您可以保留配置但是您需要定义另一个Bean来处理映射(别名)
@Bean
@Primary
@ConfigurationProperties("app.datasource")
public DataSourceProperties dataSourceProperties() {
return new DataSourceProperties();
}
@Bean
@ConfigurationProperties("app.datasource")
public DataSource dataSource(DataSourceProperties properties) {
return properties.initializeDataSourceBuilder().
.build();
}
