java - Spring boot : java. lang.IllegalArgumentException:driverClassName 需要 jdbcUrl

标签 java database spring-boot jpa

在我的 Spring boot 项目中，我尝试使用 JPA 配置两个数据库(H2 和 Postgres)。 这是我的配置类:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "entityManagerFactory",
        basePackages = {"uz.tarv.ahmad.entities.h2"})
public class H2Config {
    @Autowired
    Environment env;

    @Primary
    @Bean(name = "dataSource")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource postgresDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Primary
    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("dataSource") DataSource dataSource
    ) {
        return builder
                .dataSource(dataSource)
                .packages("uz.tarv.ahmad.entities.h2")
                .persistenceUnit("default")
                .build();
    }

    @Primary
    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager(
            @Qualifier("entityManagerFactory")EntityManagerFactory entityManagerFactory){
        return new JpaTransactionManager(entityManagerFactory);
    }
}

和

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "pgEntityManagerFactory",
        transactionManagerRef = "pgTransactionManager",
        basePackages = {"uz.tarv.ahmad.entities.postgres"})
public class PostgresConfig {

    @Bean(name = "pgDataSource")
    @ConfigurationProperties(prefix = "postgres.datasource")
    public DataSource postgresDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean("pgEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean pgEntityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("pgDataSource") DataSource dataSource
    ) {
        return builder
                .dataSource(dataSource)
                .packages("uz.tarv.ahmad.entities.postgres")
                .persistenceUnit("pg")
                .build();
    }

    @Bean(name = "pgTransactionManager")
    public PlatformTransactionManager pgTransactionManager(
            @Qualifier("pgEntityManagerFactory")EntityManagerFactory entityManagerFactory
    ) {
        return new JpaTransactionManager(entityManagerFactory);
    }
}

application.properties 文件:

#Hibernate general settings
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

# 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
# H2
spring.h2.console.enabled=true
spring.h2.console.path=/h2  
# Datasource - h2
spring.datasource.url=jdbc:h2:mem:inmemdb
spring.datasource.username=user
spring.datasource.password=123456
spring.datasource.driver-class-name=org.h2.Driver

# PostgreSQL DB - "postgres"
postgres.datasource.url=jdbc:postgresql://localhost:5432/ahmad
postgres.datasource.username=postgres
postgres.datasource.password=postgres
postgres.datasource.driver-class-name=org.postgresql.Driver
postgres.datasource.initial-size=0
postgres.datasource.max-total=12
postgres.datasource.max-idle=12

当我尝试运行该程序时，它抛出以下异常:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'entityManagerFactory' defined in class path resource [uz/tarv/ahmad/dbConfig/H2Config.class]: Unsatisfied dependency expressed through method 'entityManagerFactory' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'entityManagerFactoryBuilder' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Unsatisfied dependency expressed through method 'entityManagerFactoryBuilder' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaVendorAdapter' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.JpaVendorAdapter]: Factory method 'jpaVendorAdapter' threw exception; nested exception is java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName.

如果您之前遇到过类似问题，请帮助我。 两天来，我阅读了所有相关问题和开源帖子，但无法弄清楚我错过了什么:(

最佳答案

如果您碰巧在类路径上有 Hikari，则此基本设置不起作用，因为 Hikari 没有 url 属性(但有 jdbcUrl 属性)。在这种情况下，您必须按如下方式重写配置:(从文档复制)

@Bean
    @Primary 
    @ConfigurationProperties("spring.datasource")
    public DataSourceProperties dataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @ConfigurationProperties("spring.datasource")
    public HikariDataSource dataSource(DataSourceProperties properties) {
        return properties.initializeDataSourceBuilder().type(HikariDataSource.class)
                .build();
    }
