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.

连了一下MySQL，改了pom

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

然后下面是application的

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

启动的时候就会出现这个错误，求各位大佬解决一下

求个大佬远程解决一下...弄了半个月没弄好QAQ

现在就是这个问题了，xml文件里要配置bean吗？我看教程好像都是没有的，下过marketplace里的jpa没用，一直是这个问题，看了网上的教程好像大家都没有这个问题...求远程QAQ

Answer 1

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 2

你有在pom.xml依赖mysql的JDBC驱动嘛

Answer 3

还是外部包有问题，检查一下org.springframework.jdbc

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

Answer 6

120%是你这个包orgspringframeworkspring-jdbc下的对应版本下载的不对，删了重新下载

Answer 7

我也遇到了类似的问题，后来尝试在我的自定义XXRepository接口上面加上了@Repository注解，就可以了

Answer 8

同问题，把pom.xml的删除，把之前能运行的项目的pom.xml的配置copy过来之后，再添加所需的配置，亲测有效

Answer 9

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