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.

Disambungkan ke MySQL dan menukar pom

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

Kemudian berikut adalah aplikasinya

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

Ralat ini akan muncul semasa memulakan, tolong bantu saya menyelesaikannya

Sila minta bos besar untuk menyelesaikan masalah dari jauh...ia mengambil masa setengah bulan dan saya belum selesai QAQ

Sekarang itulah persoalannya, adakah saya perlu mengkonfigurasi kacang dalam fail xml? Nampaknya tidak ada tutorial Saya telah memuat turun jpa di pasaran tetapi ia tidak berfungsi Saya selalu mengalami masalah ini

Answer 1

Adakah anda mempunyai pemandu JDBC yang bergantung pada mysql dalam pom.xml?

Answer 2

Masih ada masalah dengan pakej luar, semak org.springframework.jdbc

Answer 3

Saya tidak melihat konfigurasi khusus anda, jadi saya hanya boleh meneka:
Adakah kerana anda tidak melaksanakan sumber data tersuai tetapi mengecualikan sumber data lalai springboot?
Cuba alih keluar exclude = {DataSourceAutoConfiguration.class} dalam @EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class}), atau gantikannya dengan sumber data seperti druid atau dbcp.

Answer 4

Adakah anda tidak menambah kebergantungan mysql?

Saya akan menghantar kepada anda konfigurasi yang saya gunakan baru-baru ini untuk rujukan anda:
Saya akan menghantar kepada anda konfigurasi yang diperlukan dan meninggalkan konfigurasi yang lain
1.pom.xml konfigurasi:

<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 konfigurasi

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

Muat turun semula jpa dan tukar sumber Saya pernah menghadapi masalah ini sebelum ini
