@dangyuluo 采集卡输出的话玩喷喷有点不太跟手，休闲游戏延迟我觉得可以接受，接 hdmi 倒是没什么延迟

刚买了个海备思的采集卡+底座的转接，typec 供电诱骗出 tv 模式，可当采集卡也可以 hdmi 环出

试试 Spring 的这个类，https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/ResolvableType.html
```java
private HashMap<Integer, List<String>> myMap;
public void example() {
ResolvableType t = ResolvableType.forField(getClass().getDeclaredField("myMap"));
t.getSuperType(); // AbstractMap<Integer, List<String>>
t.asMap(); // Map<Integer, List<String>>
t.getGeneric(0).resolve(); // Integer
t.getGeneric(1).resolve(); // List
t.getGeneric(1); // List<String>
t.resolveGeneric(1, 0); // String
}
```
```java
private HashMap<Integer, List<String>> myMap;
public void example() {
ResolvableType t = ResolvableType.forField(getClass().getDeclaredField("myMap"));
t.getSuperType(); // AbstractMap<Integer, List<String>>
t.asMap(); // Map<Integer, List<String>>
t.getGeneric(0).resolve(); // Integer
t.getGeneric(1).resolve(); // List
t.getGeneric(1); // List<String>
t.resolveGeneric(1, 0); // String
}
```
已支持，加油！
