java - Gradle项目-无法配置DataSource'url'属性失败，并且无法配置任何嵌入式数据源

试图遵循https://spring.io/guides/gs/accessing-data-mysql/中的指南，但是当我启动Java应用程序时，它显示以下错误:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

这是我的application.property:

spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://localhost:3306/db_currency
spring.datasource.username=springuser
spring.datasource.password=ThePassword

数据库创建遵循以下指导:

mysql> create database db_example; -- Create the new database
mysql> create user 'springuser'@'localhost' identified by 'ThePassword';
mysql> grant all on db_example.* to 'springuser'@'localhost';

我的build.gradle是:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.0.5.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

bootJar {
    baseName = 'gs-accessing-data-mysql'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")

    // JPA Data (We are going to use Repositories, Entities, Hibernate, etc...)
    compile 'org.springframework.boot:spring-boot-starter-data-jpa'

    // Use MySQL Connector-J
    compile 'mysql:mysql-connector-java'

    testCompile('org.springframework.boot:spring-boot-starter-test')
}

最佳答案

通过研究，对于这个对其他人有用的问题，有多个答案，在我的情况下，将其添加到application.properties文件即可:

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQL94Dialect
