java写表格生成图片源代码

最近写彩信接口,需要根据配置信息自动生成图片,jfreechar可以搞定柱图,线图,饼图,柱线合图,堆栈图等等所有的,维度表格无法实现。曾经常识通过html2image实现,但是样式无法接受,没办法只能自己写,java代码。源代码如下,仅供参考

 

package table;

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.BufferedOutputStream;
import java.io.FileOutputStream;
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;

public class TestTable {
	BufferedImage image;
	void createImage(String fileLocation) {
		try {
			FileOutputStream fos = new FileOutputStream(fileLocation);
			BufferedOutputStream bos = new BufferedOutputStream(fos);
			JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(bos);
			encoder.encode(image);
			bos.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public void graphicsGeneration() {
		//实际数据行数+标题+备注
		int totalrow = 6;
		int totalcol = 5;
		int imageWidth = 1024;
		int imageHeight = totalrow*40+20;
		int rowheight = 40;
		int startHeight = 10;
		int startWidth = 10;
		int colwidth = (int)((imageWidth-20)/totalcol);
		
		image = new BufferedImage(imageWidth, imageHeight,BufferedImage.TYPE_INT_RGB);
		Graphics graphics = image.getGraphics();
		
		graphics.setColor(Color.WHITE);
		graphics.fillRect(0,0, imageWidth, imageHeight);
		graphics.setColor(new Color(220,240,240));

		//画横线
		for(int j=0;j<totalrow-1;j++){
			graphics.setColor(Color.black);
			graphics.drawLine(startWidth, startHeight+(j+1)*rowheight, imageWidth-5, startHeight+(j+1)*rowheight);
		}
		//末行
		graphics.setColor(Color.black);
		graphics.drawLine(startWidth, imageHeight-90, imageWidth-5, imageHeight-90);
		
	
		//画竖线
		for(int k=0;k<totalcol;k++){
			graphics.setColor(Color.black);
			graphics.drawLine(startWidth+k*colwidth, startHeight+rowheight, startWidth+k*colwidth, imageHeight-50);
		}
		//末列
		graphics.setColor(Color.black);
		graphics.drawLine(imageWidth-5, startHeight+rowheight,imageWidth-5, imageHeight-50);
		
		//设置字体
		Font font = new Font("华文楷体",Font.BOLD,20);
		graphics.setFont(font);
		
		//写标题
		String title = "标题写在这里";
		graphics.drawString(title, imageWidth/3+startWidth, startHeight+rowheight-10);
		
		font = new Font("华文楷体",Font.BOLD,18);
		graphics.setFont(font);
		
		//写入表头
		String[] headCells = {"编号","名称","年龄","性别","体重"};
		for(int m=0;m<headCells.length;m++){
			graphics.drawString(headCells[m].toString(), startWidth+colwidth*m+5, startHeight+rowheight*2-10);
		}
	
		//设置字体
		font = new Font("华文楷体",Font.PLAIN,16);
		graphics.setFont(font);
		String[][] cellsValue = {{"101","xiaozhang","13","M","55"},
								 {"102","xiaowang","14","F","53"},
								 {"103","xiaoli","15","M","58"}};
		//写入内容
		for(int n=0;n<cellsValue.length;n++){
			String[] arr = cellsValue[n];
			for(int l=0;l<arr.length;l++){
				graphics.drawString(cellsValue[n][l].toString(), startWidth+colwidth*l+5, startHeight+rowheight*(n+3)-10);
			}
		}
		
		font = new Font("华文楷体",Font.BOLD,18);
		graphics.setFont(font);
		graphics.setColor(Color.RED);
		
		//写备注
		String remark = "备注:备注写在这里。";
		graphics.drawString(remark, startWidth, imageHeight-30);
	
		createImage("c:\\1.jpg");
	}

	public static void main(String[] args) {
		TestTable cg = new TestTable();
		try {
			cg.graphicsGeneration();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}
