大家好，我在本地运行heroku服务器时遇到了问题，我相信不止一个错误，但我不知道主要问题是什么。我已经添加了procfile和数据库配置，如代码中所提供的。

这是我的档案

等级：

plugins {
   id 'org.springframework.boot' version '2.6.1'
   id 'io.spring.dependency-management' version '1.0.11.RELEASE'
   id 'java'
}

group = 'com.discount'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
   mavenCentral()
}

dependencies {
   implementation 'org.springframework.boot:spring-boot-starter-web'
   testImplementation 'org.springframework.boot:spring-boot-starter-test'
   implementation group: 'javax.persistence', name: 'javax.persistence-api', version: '2.2'
   implementation group: 'org.springframework.boot', name: 'spring-boot-starter-jdbc', version: '2.6.0'
   implementation group: 'org.postgresql', name: 'postgresql', version: '42.3.1'

}

test {
   useJUnitPlatform()
}

数据库配置类：

@Value("${spring.datasource.url}")
    private String dbUrl;

    @Bean
    public DataSource dataSource() {
        HikariConfig config = new HikariConfig();
        config.setJdbcUrl(dbUrl);
        return new HikariDataSource(config);
    }
}

例外情况是通知您无法创建bean，因为您尚未定义属性spring.datasource.url。
如果你使用的是yml配置，（例如在src/main/resources中你有application.yml文件），打开它并在“spring”下添加datasource属性：

spring:
  datasource:
    url: # db connection url here

如果使用的是属性文件，则格式更改为

spring.datasource.url= # db connection url here

我遇到了同样的问题。尽管我的配置是正确的：

spring.datasource.url=jdbc:postgresql://localhost:5432/<your_data_base_name>

我错过了maven依赖：

<dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <scope>runtime</scope>
        </dependency>
