Java生成表格图片的实例代码

Java生成表格图片的实例代码

主要代码：

/**

* 生成图片

* @param cellsValue 以二维数组形式存放 表格里面的值

* @param path 文件保存路径

*/

public void myGraphicsGeneration(String cellsValue[][], String path) {

// 字体大小

int fontTitileSize = 15;

// 横线的行数

int totalrow = cellsValue.length+1;

// 竖线的行数

int totalcol = 0;

if (cellsValue[0] != null) {

totalcol = cellsValue[0].length;

}

// 图片宽度

int imageWidth = 1024;

// 行高

int rowheight = 40;

// 图片高度

int imageHeight = totalrow*rowheight+50;

// 起始高度

int startHeight = 10;

// 起始宽度

int startWidth = 10;

// 单元格宽度

int colwidth = (int)((imageWidth-20)/totalcol);

BufferedImage 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

graphics.setColor(Color.black);

graphics.drawLine(startWidth, startHeight+(j+1)*rowheight, startWidth+colwidth*totalcol, startHeight+(j+1)*rowheight);

}

//画竖线

for(int k=0;k

graphics.setColor(Color.black);

graphics.drawLine(startWidth+k*colwidth, startHeight+rowheight, startWidth+k*colwidth, startHeight+rowheight*totalrow);

}

//设置字体

Font font = new Font("微软雅黑",Font.BOLD,fontTitileSize);

graphics.setFont(font);

//写标题

String title = "【指标完成进度】";

graphics.drawString(title, startWidth, startHeight+rowheight-10);

//写入内容

for(int n=0;n

for(int l=0;l

if (n == 0) {

font = nhttp://ew Font("微软雅黑",Font.BOLD,fontTitileSize);

graphics.setFont(font);

}else if (n > 0 && l >0) {

graphics.setFont(font);

graphics.setColor(Color.RED);

} else {

graphics.setFont(font);

}

graphics.drawString(cellsValue[n][l].toString(), startWidth+colwidth*l+5, startHeight+rowheight*(n+2)-10);

}

}

// 保存图片

createImage(image, path);

}

/**

* 将图片保存到指定位置

* @param image 缓冲文件类

* @param fileLocation 文件位置

*/

public void createImage(BufferedImage image, 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();

}

}

测试代码：

public static void main(String[] args) {

DrawTableImg cg = new DrawTableImg();

try {

String tableData1[][] = {{"8月31日","累计用户数","目标值","完成进度","时间进度", "进度差异"}, {"掌厅客户端（户）","469281","1500000","31.2%","33.6%", "-2.4%"}};

String[][] tableData2 = {{"8月31日（户）","新增用户数","日访问量","累计用户数","环比上月"},

{"合肥和巢湖","46928UBecEGC1","1500000","31.2%","33.6%"},

{"芜湖","469281","1500000","31.2%","33.6%"},

{"蚌埠","469281","1500000","31.2%","33.6%"},
