即使使用限定符，也无法自动装配2个相同类型但名称不同的bean

Question

我正在开发一个spring-boot应用程序，我有一个配置类，我在其中定义了2个相同类型但具有不同名称的bean，我使用该bean作为不同bean的参数，我使用限定符来有不同的名称，但我仍然无法自动装配豆

import com.typesafe.config.Config;
import com.typesafe.config.ConfigFactory;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;

import javax.sql.DataSource;
import java.io.File;

/**

@Configuration
public class DbConfig {

    @Bean(name = "sourceJdbcTemplate")
    public JdbcTemplate sourceJdbcTemple(@Qualifier("srcDataSource") DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }


    @Bean(name = "srcDataSource")
    public DataSource sourceDataSource(Config config) {
        String driverClassName = config.getString("dbPullConfig.Database.Source.driver");
        String url = config.getString("dbPullConfig.Database.Source.url");
        String userName = config.getString("dbPullConfig.Database.Source.username");
        String password = config.getString("dbPullConfig.Database.Source.password");

        DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
        driverManagerDataSource.setDriverClassName(driverClassName);
        driverManagerDataSource.setUrl(url);
        driverManagerDataSource.setUsername(userName);
        driverManagerDataSource.setPassword(password);

        return driverManagerDataSource;
    }

    @Bean(name = "destDataSource")
    public DataSource destinationDataSource(Config config) {
        String driverClassName = config.getString("dbPullConfig.Database.Destination.driver");
        String url = config.getString("dbPullConfig.Database.Destination.url");
        String userName = config.getString("dbPullConfig.Database.Destination.username");
        String password = config.getString("dbPullConfig.Database.Destination.password");

        DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
        driverManagerDataSource.setDriverClassName(driverClassName);
        driverManagerDataSource.setUrl(url);
        driverManagerDataSource.setUsername(userName);
        driverManagerDataSource.setPassword(password);

        return driverManagerDataSource;
    }

    @Bean(name = "config")
    public Config config() {
        return ConfigFactory.parseFile(new File("DbPullConfig.conf"));
    }
}

我收到以下错误

parameter 0 of method sourceJdbcTemple in com.ambuj.risk.DbConfig required a single bean, but 2 were found:
    - srcDataSource: defined by method 'sourceDataSource' in class path resource [com/ambuj/risk/DbConfig.class]
    - destDataSource: defined by method 'destinationDataSource' in class path resource [com/ambuj/risk/DbConfig.class]
