Spring Boot多个数据源

Question

我有一个使用1.5.1版本spring boot的应用程序的问题。

@Configuration
public class OracleDBConfig {

    @Bean(name = "oracleDb")
    @ConfigurationProperties(prefix = "spring.ds_oracle") 
    public DataSource oracleDataSource() {
        return  DataSourceBuilder.create().build();
    }

    @Bean(name = "oracleJdbcTemplate")
    public JdbcTemplate oracleJdbcTemplate(@Qualifier("oracleDb") DataSource dsOracle) {
        return new JdbcTemplate(dsOracle);
    }
}

    @Bean(name = "mysqlDb")
    @ConfigurationProperties(prefix = "spring.ds_mysql")
    public DataSource mysqlDataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "mysqlJdbcTemplate")
    public JdbcTemplate mySQLjdbcTemplate(@Qualifier("mysqlDb")DataSource dsMySQL) {
        return new JdbcTemplate(dsMySQL);
    }
}

启动程序时出现以下错误：

Parameter 0 of method oracleJdbcTemplate in com.bv.aircraft.config.OracleDBConfig required a single bean, but 2 were found:
    - mysqlDb: defined by method 'mysqlDataSource' in class path resource [com/bv/aircraft/config/MySQLDBConfig.class]
    - oracleDb: defined by method 'oracleDataSource' in class path resource [com/bv/aircraft/config/OracleDBConfig.class]

我尝试使用@primary，但当我需要使用其他数据源时，它不起作用。

谢谢你

在Spring Boot配置类中添加以下内容

@EnableAutoConfiguration(exclude = {DataSourceTransactionManagerAutoConfiguration.class, DataSourceAutoConfiguration.class})

示例用法：

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceTransactionManagerAutoConfiguration.class, DataSourceAutoConfiguration.class})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
