1.4 然后请关注一个知识 泛型,TypeToken(Guava)其中的$Gson$Types.canonicalize(parameterized.getActualTypeArguments()[0]),这个就是获取,就是泛型类型转换Type的关键点。这里用的是Gson进行转换。 这样得到的Type将可以作为Gson数据转换使用。解决了我们只能靠判断写死的情况: 实际上大概是这样: Student student = ...
在获取泛型类型时，通常需要使用ParameterizedType。通过getGenericSuperclass获取的类型就是ParameterizedType，接着通过getActualTypeArguments方法获取对应的泛型类型，即数组的第0个值。为了解决转换问题，可以使用Gson进行转换，关键在于TypeToken（Guava）中的Gson$Types.canonicalize(parameterized.getActualTypeArgumen...

>ParameterizedType represents a parameterized type such as Collection<String>.A parameterized type is created the first time it is needed by a reflective method, as specified in this package. When a parameterized type p is created, the generic type declaration that p instantiates is resolved, and ...
非泛型类型不是Raw Type 示例: class Ra <T>{ public void fun(T t){} } //只是个泛型类型声明 class Rb { public void fun( ){} } //只是个类声明 public class RawTypes { @Test public void testRawType(){ Ra<Integer> rai = new Ra<>(); //Ra<Integer> is parameterized type Ra ra ...
Type superclass = callback.getClass().getGenericSuperclass(); // 如果实现类没有范型信息,直接返回 if (!(superclass instanceof ParameterizedTypeImpl)) { return; } try { // 找到声明的具体类型 ParameterizedType parameterized = (ParameterizedType) superclass; ...
