我试图设置一个带有两个数据源的spring boot项目。
一个用于装载，一个用于存储。
申请道具
# Primary DataSource
datasource.primary.url=url
datasource.primary.username=root
datasource.primary.password=password
datasource.primary.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
# Secondary DataSource
datasource.secondary.url=url
datasource.secondary.username=root
datasource.secondary.password=password
datasource.secondary.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
主数据库的配置类
package com.anders.cphbusiness.db;
import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.persistence.PersistenceContext;
import javax.sql.DataSource;
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.anders.cphbusiness.entitiesModel", entityManagerFactoryRef = "entityManager")
public class LoadDataSourceConfig {
@Bean(name = "dataSource")
@Primary
@ConfigurationProperties(prefix = "datasource.primary")
public DataSource loadingDataSource() {
return DataSourceBuilder.create().build();
}
@PersistenceContext(unitName = "primary")
@Primary
@Bean(name = "entityManager")
public LocalContainerEntityManagerFactoryBean loadingEntityManagerFactory(EntityManagerFactoryBuilder builder) {
return builder.dataSource(loadingDataSource()).persistenceUnit("primary").packages("com.anders.cphbusiness.entitiesModel").build();
}
}
辅助数据库的配置类
package com.anders.cphbusiness.db;
import org.springframework.boot.autoconfigure.jdbc.DataSourceBuilder;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import javax.persistence.PersistenceContext;
import javax.sql.DataSource;
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "com.anders.cphbusiness.storingModel", entityManagerFactoryRef = "secondaryEntityManager", transactionManagerRef = "secondaryTransactionManager")
public class StoreDataSourceConfig {
@Bean
@ConfigurationProperties(prefix = "datasource.secondary")
public DataSource storingDataSource() {
return DataSourceBuilder.create().build();
}
@PersistenceContext(unitName = "secondary")
@Bean(name = "secondaryEntityManager")
public LocalContainerEntityManagerFactoryBean storingEntityManagerFactory(
EntityManagerFactoryBuilder builder) {
return builder
.dataSource(storingDataSource())
.packages("com.anders.cphbusiness.storingModel")
.persistenceUnit("secondary")
.build();
}
@Bean(name = "secondaryTransactionManager")
public PlatformTransactionManager transactionManager(EntityManagerFactoryBuilder builder) {
JpaTransactionManager tm = new JpaTransactionManager();
tm.setEntityManagerFactory(storingEntityManagerFactory(builder).getObject());
tm.setDataSource(storingDataSource());
return tm;
}
}
我在控制器中的回购抱怨它。
@Autowired
private wagerBoardMarksRepo repo;
实际回购
package com.anders.cphbusiness.repositories;
import com.anders.cphbusiness.entitiesModel.WagerBoard;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface WagerBoardRepo extends JpaRepository<WagerBoard, String> {
}

Description:
Field repo in com.anders.cphbusiness.controller.restController required a bean of type 'com.anders.cphbusiness.repositories.wagerBoardMarksRepo' that could not be found.
Action:
Consider defining a bean of type 'com.anders.cphbusiness.repositories.wagerBoardMarksRepo' in your configuration.
任何建议 - 提示 - 使用多个数据源设置弹簧引导的指南（最好使用带有两个数据源的项目的工作git）
