Reason
JDK needs to read the font list from the font configuration file, and the default font list does not have a Chinese font.
2. Solution
Add Chinese fonts for JDK font profiles
3. Procedure
3.1. Copy the font file to the font directory of JDK
CD / USR / local / java / jre / lib / fontscp /usr/share/fonts/en_cn/TrueType/gbsn00l.ttf.
3.2. Generate a font list file
TTMKFDIR -O FONTS.DIR
3.3. View the newly generated fonts.dir file to view the part about GBSN00L.TTF
VI FONTS.DIR
3.4. Should be on the last line of the file
-ARPHIC TECHNOLOGY CO.-AR PL SUNGTIL GB-Medium-R-NORMAL - 0-0-0-0-P-0-ASCII-0
3. Return to the previous point of directory, join GBSN00LP.TTF to Font.properties
Cd ..vi font.properties
3.6. Add method:
3.6.1 First copy the line of text seen in 3.4, will
0-0-0-0-P-0 change to * -% D - * - * - P- *
The purpose is to make the font to scale, now it is:
-ARPHIC TECHNOLOGY Co.-AR PL SUNGTIL GB-Medium-R-NORMAL - * -% D - * - * - P - * - ASCII-0
3.6.2 Font.Properties files have been included in 0 and 1 font, such as the first line is Serif.0, the second line is SeriF.1, then you need to add
Serif.2 = -ARPHIC TECHNOLOGY Co. - AR PL SUNGTIL GB-Medium-R-NORMAL - * -% D - * - * - P - * - ASCII-0
3.6.3 Pushing in this class, adding XXXX.2 below each XXXX.2 until the # missing glyph character before the file.
3.6.4 Add completion, save the disk exits.
3.7. Add environment variable Java_FONTS
Vi / etc / profilejava_fonts = $ java_home / jre / lib / fonts
3.8. Replace to make environment variables
