Description:

Parameter 0 of constructor in org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
    - Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType'
    - Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseType'


Action:

Consider revisiting the conditions above or defining a bean of type 'javax.sql.DataSource' in your configuration.

Mit MySQL verbunden und POM geändert

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

Dann ist das Folgende die Anwendung

spring.datasource.url = jdbc:mysql://localhost:1204/test
spring.datasource.username = root
spring.datasource.password = 1204
spring.datasource.driverClassName = com.mysql.jdbc.Driver
# Specify the DBMS
spring.jpa.database = MYSQL
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = update
# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# stripped before adding them to the entity manager)
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

Dieser Fehler wird beim Starten angezeigt. Bitte helfen Sie mir, ihn zu beheben

Bitte bitten Sie einen großen Chef, das Problem aus der Ferne zu lösen ... es hat einen halben Monat gedauert und ich habe die QAQ noch nicht abgeschlossen

Das ist nun die Frage: Muss ich Beans in der XML-Datei konfigurieren? Es scheint, dass es keine Tutorials auf dem Marktplatz gibt, aber es funktioniert nicht. Nachdem ich die Tutorials online gelesen habe, scheint es, dass niemand dieses Problem hat ... Bitte Remote-QAQ

Answer 1

你有在pom.xml依赖mysql的JDBC驱动嘛

Answer 2

还是外部包有问题，检查一下org.springframework.jdbc

Answer 3

没有看到你的具体配置，只好猜测了：
是不是没有进行自定义数据源实现反而把springboot默认的数据源排除掉了？
试试把@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})中的exclude = {DataSourceAutoConfiguration.class}去掉，或者使用druid或者dbcp之类的数据源替换。

Answer 4

是不是没加mysql依赖？

发个我自己最近在用的配置，供你参考：
就发个必要配置，其他的省略
1.pom.xml配置：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>

2.application.properties配置

spring.datasource.url=jdbc:mysql://localhost:3306/vgift
spring.datasource.username=voson
spring.datasource.password=123
spring.datasource.driverClassName=com.mysql.jdbc.Driver
# hibernate 配置
spring.jpa.database=MYSQL
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

Answer 5

重新下载jpa,换个源,我之前也碰到过这问题
