TypeCodec.accepts介绍

[英]Return true if this codec is capable of serializing the given javaType.

The implementation is invariant with respect to the passed argument (through the usage of TypeToken#equals(Object)and it's strongly recommended not to modify this behavior. This means that a codec will only ever return true for the exact Java type that it has been created for.

If the argument represents a Java primitive type, its wrapper type is considered instead.
[中]如果此编解码器能够序列化给定的javaType，则返回true。
对于传递的参数，实现是不变的（通过使用TypeToken#equals（Object））并且强烈建议不要修改此行为。这意味着编解码器只会为其创建的exactJava类型返回true。
如果参数表示Java基元类型，则考虑其包装器类型。
