OrientDB在使用Unicode，土耳其语和枚举时遇到麻烦 [英] OrientDB having trouble with Unicode, Turkish, and enums
问题描述
我正在使用具有枚举类型且具有此类const的lib;
Type.SHORT
Type.LONG
Type.FLOAT
Type.STRING
当我在Eclipse中调试时，出现错误:
No enum const class Type.STRİNG
当我使用土耳其语系统时，在使用i>İ时会出现问题，但是由于这是一个枚举常量，即使我将每个属性都设置为UTF-8，也无法得到 STRING 是Eclipse应该寻找的东西.但是它仍在寻找STRİNG，但找不到，我无法使用它.我该怎么办?
项目>属性>资源>文本文件编码现在为UTF-8.问题一直存在.
编辑:更多信息可能会提供一些我无法获得的线索； 我正在研究OrientDB.这是我的第一次尝试，因此我不知道问题是否可能出在OrientDB软件包上.但是我正在使用许多其他库，但从未见过这样的问题.该程序包中有一个OType枚举，我只是尝试连接到数据库.
String url = "local:database";
ODatabaseObjectTx db = new ODatabaseObjectTx(url).
Person person = new Person("John");
db.save(person);
db.close();
我没有更多的代码了.创建数据库，但随后出现java.lang.IllegalArgumentException:

这是OType类:解决方案
我正确地假设您正在使用土耳其语区域设置运行该程序吗?然后，该错误似乎在OCommandExecutorSQLCreateProperty的第118行中:
linkedType = OType.valueOf(linked.toUpperCase());
您必须指定应使用其大写字母规则的语言环境，可能将Locale.ENGLISH用作toUpperCase的参数.
I am using a lib which has an enum type with consts like these;
Type.SHORT
Type.LONG
Type.FLOAT
Type.STRING
While I am debugging in Eclipse, I got an error:
No enum const class Type.STRİNG
As I am using a Turkish system, there is a problem on working i>İ but as this is an enum const, even though I put every attributes as UTF-8, nothing could get that STRING is what Eclipse should look for. But it still looks for STRİNG and it can't find and I can't use that. What must I do for that?
Project > Properties > Resouce > Text file encoding is UTF-8 now. Problem keeps.
EDIT: More information may give some clues which I can't get; I am working on OrientDB. This is my first attempt, so I don't know if the problem could be on OrientDB packages. But I am using many other libs, I have never seen such a problem. There is a OType enum in this package, and I am only trying to connect to the database.
String url = "local:database";
ODatabaseObjectTx db = new ODatabaseObjectTx(url).
Person person = new Person("John");
db.save(person);
db.close();
There is no more code I use yet. Database created but then I get the java.lang.IllegalArgumentException:

Here is OType class: http://code.google.com/p/orient/source/browse/trunk/core/src/main/java/com/orientechnologies/orient/core/metadata/schema/OType.java
And other class; OCommandExecutorSQLCreateProperty: http://code.google.com/p/orient/source/browse/trunk/core/src/main/java/com/orientechnologies/orient/core/sql/OCommandExecutorSQLCreateProperty.java
Line 81 says: type = OType.valueOf(word.toString());
Am I correct to assume you are running this program using a turkish locale? Then it seems the bug is in line 118 of OCommandExecutorSQLCreateProperty:
linkedType = OType.valueOf(linked.toUpperCase());
You would have to specify the Locale whose upper casing rules should be used, probably Locale.ENGLISH as the parameter to toUpperCase.
