在linux下中文显示乱码，按网上说的是在linux下找不到对应的字库，如“宋体”等，所以出现乱码。
虽然下面这个方法可以解决乱码的问题，但是要修改linux字库有些麻烦，希望有其它方法的ggmm把它贴出来：）
解决办法是往linux中添加支持中文的字库，如simsun
1. 把window下：c:/windows/fonts下的字库simsun.ttc 拷贝到/usr/share/fonts/zh_CN/TrueType 下 （如果没有这个目录就新一个）
2. 在jdk目录下的/jre/lib下
新建一个名为“font.properties.zh.Redhat1.0”的文件，内容如下：
# @(#)font.properties.ja.linux 1.7 02/03/07
#
# Copyright 2002 Sun Microsystems, Inc. All rights reserved.

# Component Font Mappings For RedhatLinux 8.0/zh_CN
