Spring boot (21)多数据源引起的循环引用和AutoConfigureAfter失效的问题

1.问题起因

目前写SPringBoot引入多数据源路由
遇到了需要控制加载顺序的问题

@Configuration
@MapperScan(basePackages = "com.gaotianyue.dao")
public class DataSourceConfig {
   
     第一步
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource1() {
        return DataSourceBuilder.create().build();
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource2() {
        return = DataSourceBuilder.create().build();
    }
}

@Configuration
public class RoutingDataSourceConfig {
   
     第二步
    @Bean(name="rwDataSource")
    public ReadWriteRoutingDataSource rwDataSource(@Qualifier("dataSource1") DataSource dataSource1, @Qualifier("dataSource2") DataSource dataSource2) {
        ReadWriteRoutingDataSource ds = new ReadWriteRoutingDataSource();
        Map<Object, Object> targetDataSources = new HashMap<>();
        targetDataSources.put(Master.class, dataSource1);
        targetDataSources.put(Slave.class, dataSource2);
        ds.setTargetDataSources(targetDataSources);
        ds.setDefaultTargetDataSource(dataSource1);//默认数据源
        return ds;
    }
    第三部报错
    @Bean
    public SqlSessionFactory ds1SqlSessionFactory(@Qualifier("rwDataSource") ReadWriteRoutingDataSource dataSource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dataSource);
        bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mappers/*.xml"));
        return bean.getObject();
    }
}

两段程序本来在一个类中
引用情况如下：

            |----<>SqlSessionFactoryBean 
                      |
                      |<>-- -- DataSource
                      |           /|\
                      |            |
                      |<>-- -- RWRoutingDataSoure
                                      |
                                      |<>---DataSource

启动后发现出现循环引用错误
单独保留DataSource RWRoutingDataSour
