【问题描述】:
尝试按照 https://spring.io/guides/gs/accessing-data-mysql/ 中的指南进行操作,但是当我启动我的 java 应用程序时,它显示错误:
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南:
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';
而我的 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')
}
【问题讨论】:
-
放置配置数据的文件应命名为 application.properties 而不是 applicaiton.property
-
它被命名为“application.properties”
-
其实我想知道这是否是 Intellij Idea 的错误。当我一次打开我的项目时发生了这个错误。然后我克隆我的代码并在另一个文件夹中构建我的项目,它似乎工作。我觉得 Intellij Idea 在 Mac 上的 gradle 效果不太好
