我正为MessageBodyWriter撰写java.util.Properties。
@Override
public void writeTo(final Properties t, final Class<?> type,
final Type genericType, final Annotation[] annotations,
final MediaType mediaType,
final MultivaluedMap<String, Object> httpHeaders,
final OutputStream entityStream)
throws IOException, WebApplicationException {
LOGGER.log(Level.INFO, "writeTo({0}, {1}, {2}, {3}, {4}, {5}, {6})",
new Object[]{t, type, genericType, annotations, mediaType,
httpHeaders, entityStream});
if (MediaType.APPLICATION_XML_TYPE.isCompatible(mediaType)) {
t.storeToXML(entityStream, null);
return;
}
if (MediaType.APPLICATION_JSON_TYPE.isCompatible(mediaType)) {
final JsonGenerator generator =
JSON_FACTORY.createGenerator(entityStream);
generator.writeStartObject();
for (String stringPropertyName : t.stringPropertyNames()) {
generator.writeFieldName(stringPropertyName);
generator.writeString(t.getProperty(stringPropertyName));
//generator.writeStringField(stringPropertyName,
// t.getProperty(stringPropertyName));
}
generator.writeEndObject();
return;
}
throw new WebApplicationException(
Response.Status.UNSUPPORTED_MEDIA_TYPE);
}
当我使用application/xml请求时，它似乎工作正常。

但是当我尝试在application/json条目上java.library.path输出结果修剪时。

请参阅？在提供java.library.path的价值时停止。
我做错了吗？这是杰克逊的错吗？这是G / F的缓冲问题吗？
这是System.out为值打印的内容。
