类 CharsetMapping

  • 直接已知子类:
    NativeCharsetSettings
    public class CharsetMapping
extends Object
    Mapping between MySQL charset names and Java charset names. I've investigated placing these in a .properties file, but unfortunately under most appservers this complicates configuration because the security policy needs to be changed by the user to allow the driver to read them :(

        MySQL charset could map to several Java encodings. So here we choose the one according to next rules:
        • if there is no static mapping for this charset then return javaEncoding value as is because this could be a custom charset for example
        • if static mapping exists and javaEncoding equals to one of Java encoding canonical names or aliases available for this mapping then javaEncoding value as is; this is required when result should match to connection encoding, for example if connection encoding is Cp943 we must avoid getting SHIFT_JIS for sjis mysql charset
        • if static mapping exists and javaEncoding doesn't match any Java encoding canonical names or aliases available for this mapping then return default Java encoding (the first in mapping list)
        参数:
        mysqlCharsetName - MySQL charset name
        fallbackJavaEncoding - fall-back java encoding name
        返回:
        java encoding name
