Question

我不确定为什么Spring Boot无法识别我认为配置正确的第二个数据源。

我一直收到以下消息：...Error creating bean with name 'leadRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.ref.api.test.lead.model.LeadEntity

我为.packages("com.ref.api.test.lead.model")设置了正确的路径，但是由于某些原因，spring-boot不会在那里检查我的实体。

PrimaryDsConfig

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "entityManagerFactory",
        basePackages = { "com.ref.api.repository" }
)
public class PrimaryDsConfig {

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

    @Primary
    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean
    entityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("dataSource") DataSource dataSource
    ) {
        return builder
                .dataSource(dataSource)
                .packages("com.ref.api.model")
                .persistenceUnit("foo")
                .build();
    }

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

}

AdditionDsConfig

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "barEntityManagerFactory",
        transactionManagerRef = "barTransactionManager",
        basePackages = { "com.ref.api.test.lead.repository" }
)
public class AdditionDsConfig {

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

    @Bean(name = "barEntityManagerFactory")
    public LocalContainerEntityManagerFactoryBean
    barEntityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("barDataSource") DataSource dataSource
    ) {
        return
                builder
                        .dataSource(dataSource)
                        .packages("com.ref.api.test.lead.model")
                        .persistenceUnit("bar")
                        .build();
    }

    @Bean(name = "barTransactionManager")
    public PlatformTransactionManager barTransactionManager(
            @Qualifier("barEntityManagerFactory") EntityManagerFactory
                    barEntityManagerFactory
    ) {
        return new JpaTransactionManager(barEntityManagerFactory);
    }

LeadEntity

package com.ref.api.test.lead.model;

import lombok.AllArgsConstructor;
import lombok.Getter;

        allocationSize = 1)
public class LeadEntity implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "lead_id_seq")

LeadRepository

package com.ref.api.test.lead.repository;

import com.ref.api.test.lead.model.LeadEntity;
import org.springframework.data.jpa.repository.JpaRepository;


public interface LeadRepository extends JpaRepository<LeadEntity, Long> {
}

ApiApplication

@SpringBootApplication
@EnableJpaRepositories(repositoryFactoryBeanClass = EntityGraphJpaRepositoryFactoryBean.class)
@EnableCaching
public class ApiApplication {

Answer 1

我弄清楚了为什么spring-boot没有检测到我的第二个数据源。因为我的@EnableJpaRepositories上有public class ApiApplication，所以很困惑。当我将repositoryFactoryBeanClass = EntityGraphJpaRepositoryFactoryBean.class移到PrimaryDsConfig时，一切开始正常工作。因此，请注意您有多少@EnableJpaRepositories。

为什么Spring Boot无法识别我的第二个数据源配置？
