Ubuntu下Jfreechart输出图片中文乱码问题的解决方法

产生原因：

因为你引用了Ubuntu系统没有或者不支持的字体。

比如：

Font f = new Font("宋体",Font.PLAIN,12);

但是系统里面没有“宋体”支持。所以就产生了乱码。

解决方法

给系统添加字体支持，和安装相应字体。

如何查看系统支持的字体

可以用下面的Java程序，执行并查看

import java.awt.Font;

import java.awt.Graphics;

import java.awt.GraphicsEnvironment;

import java.awt.image.BufferedImage;

import java.io.File;

import javax.imageio.ImageIO;

import javax.imageio.stream.FileImageOutputStream;

public class FontTest {

public static void outFonts() {

GraphicsEnvironment ge = GraphicsEnvironment

.getLocalGraphicsEnvironment();

String[] b = ge.getAvailableFontFamilyNames();

System.out.println(b.length);

for(int i=0;i<b.length;i++){

System.out.println(b[i]);

}

Font[] fs = ge.getAllFonts();

for(int j=0;j<fs.length;j++){

System.out.println("font:"+fs[j]);

}

/**

* @param args

public static void main(String[] args) throws Exception {

// generate("/tmp/b.png");

outFonts();

System.out.println("output image successfully");

}

"FontTest.java" 42L, 818C 1,0-1 Top

通过上面的字体支持你可以发现，

“文鼎ＰＬ简报宋”字体是支持中文的。

所以如果你设置

Font f = new Font("文鼎ＰＬ简报宋",Font.PLAIN,12);

就不会出现乱码了。

字体的安装方法

请参阅 ubuntu系统下的字体安装

安装完成，执行上面的系统支持字体程序，可以看到如下结果：
