Java Spring启动-多个配置类-导入不工作

（首次在此论坛上发布问题，请忽略任何愚蠢的东西） 正在处理面向fresh Spring引导的项目，该项目具有多个配置类（安全、DataSourceConfig、DataConfig）。问题是DataConfig正在使用DataSourceConfig中定义的某个bean，但是由于DataConfig是先加载的，所以它没有获得该依赖关系

@Configuration
public class DataSourceConfig {

    @Bean(name="abcDataSource")
    public DataSource abcDataSource() {
        final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
        dsLookup.setResourceRef(true);
        DataSource dataSource = dsLookup.getDataSource("java:comp/env/jdbc/ABC");
        return dataSource;
    }

    @Bean(name="xyzDataSource")
    @Lazy
    public DataSource xyzDataSource() {
        final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
        dsLookup.setResourceRef(true);
        DataSource dataSource = dsLookup.getDataSource("java:comp/env/jdbc/XYZ");
        return dataSource;
    }
}

@Import({DataSourceConfig.class})
@Configuration
public class DataConfig {

    @Autowired 
    DataSource xyzDataSource;

    @Bean
    public PropertyPlaceholderConfigurer propertyPlaceholderConfigurer() throws Exception {
        PropertyPlaceholderConfigurer p = new PropertyPlaceholderConfigurer();
        p.setProperties(commonsConfigurationFactoryBean());
        return p;
    }

    @Bean
    public Properties commonsConfigurationFactoryBean() {
        return ConfigurationConverter.getProperties(databaseConfiguration());
    }

    @Bean
    @Autowired
    public DatabaseConfiguration databaseConfiguration() {
        return new DatabaseConfiguration(xyzDataSource, "Table_Name", "Key_Column", "Value_Column");

    }
}

因此，当我在调试模式下启动TOMCAT服务器（不是嵌入式服务器）时，在DataConfig.databaseConfiguration（）和DataSourceConfig.xyzDataSource（）上有断点，它总是转到前一个服务器，而不是后一个服务器，这会导致问题，并给出“NullPointerException”来表示无法获取数据源

我不知道为什么“@Import”不适用于此。任何帮助都是非常感激的。请让我知道，如果你需要任何其他信息从我的结束

异常跟踪：
