objectMapper.canSerialize SpringMVC实体转JSON字符串





this.objectMapper.canSerialize(clazz, causeRef)




     * Method that can be called to check whether mapper thinks
     * it could serialize an instance of given Class.
     * Check is done
     * by checking whether a serializer can be found for the type.
     * NOTE: since this method does NOT throw exceptions, but internal
     * processing may, caller usually has little information as to why
     * serialization would fail. If you want access to internal {@link Exception},
     * call {@link #canSerialize(Class, AtomicReference)} instead.
     * @return True if mapper can find a serializer for instances of
     *  given class (potentially serializable), false otherwise (not
     *  serializable)
    public boolean canSerialize(Class<?> type) {
        return _serializerProvider(getSerializationConfig()).hasSerializerFor(type, null);

     * Method similar to {@link #canSerialize(Class)} but that can return
     * actual {@link Throwable} that was thrown when trying to construct
     * serializer: this may be useful in figuring out what the actual problem is.
     * @since 2.3
    public boolean canSerialize(Class<?> type, AtomicReference<Throwable> cause) {
        return _serializerProvider(getSerializationConfig()).hasSerializerFor(type, cause);
