Java 即使在使用限定符之后，也无法自动连接相同类型但名称不同的2个bean

我正在开发一个spring启动应用程序，我有一个配置类，在这个类中我定义了两个类型相同但名称不同的bean，我使用这个bean作为另一个bean的参数，我使用限定符来定义不同的名称，但我仍然无法自动连接这个bean

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"));
    }
}

我得到了下面的错误

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]

use@primary annotation，它主要用于您的项目中您使用的是哪个版本的Spring？这看起来是正确的。还请注意，您可以在同一配置类上的

@Bean

方法中使用方法调用

sourceDataSource（）

，这对于您的情况可能已经足够了。@AmbujJauhari您还可以包括导入语句吗？我能想到的唯一一种情况是，您正在使用其他库（如javax.inject.Qualifier）中的限定符注释。@KalaiselvanA是一种将数据从1数据库复制到另一数据库的工具，在大多数情况下，我们都有源和目标数据源。@yaswanth添加了导入语句，我使用的是“org.springframework.beans.factory.annotation.Qualifier”注释
