User+String name+int age+getName() : String+getAge() : intSerializeExample+main(String[] args)+serialize(User user) : void+deserialize(byte[] userBytes) : User 结尾 通过上述步骤,我们成功将 Java 对象的字节码反序列化为JSONObject。这一过程涉及到序列化、反序列化以及 JSON 的转换,每一环节都...

_deserializeFromString(p, ctxt); } } } Map<Object, Object> result 这样的返回类型更是表明了在回传过程中其实根本没有确定类型 实际上,最底层new Map的实例时,是没有使用泛型信息的,而在json逐字段解析值的时候,用上了JavaType带来的泛型信息。 在这个过程中,contex里头会定义一个ConcurrentHashMap,里面...
