走注解式ioc吧

@IocBean
public class MyBeans {
 
    @IocBean(name="dataSource")
    public YamlShardingDataSource createDataSource(){
        return new YamlShardingDataSource(getClass().getResourceAsStream(.....));

    }
}

@wendal 

File file = new File("sharding-jdbc.yaml");
    	Files.write(file,getClass().getResourceAsStream("sharding-jdbc.yaml"));
    	return new YamlShardingDataSource(file);

请问大佬怎么转file对象

getClass.getClassLoader.getResourceStream

nu不要涉及到File类了

maven项目？是放在resources下面的吧？

@wendal 嗯嗯，maven项目 是在resources下面

那用getClass.getClassLoader.getResourceStream
就好了，好像能接受InputStream的吧，如果不能，Streams类有帮助方法变成字符串

@wendal 谢谢 解决了，能接受字节数组

   public YamlShardingDataSource createDataSource() throws IOException, SQLException{
    	return new YamlShardingDataSource("sharding-jdbc",Streams.readBytes(getClass().getClassLoader().getResourceAsStream("sharding-jdbc.yaml")));
    }

好的，报个issue吧
