java在图片上写入文字-IDNo身份证生成方法

1、IDCardGenerate.java(接口)--//接口的定义,接口里只包含常量和抽象方法.

public interface IDCardGenerate {
//public static final String outPath = "D:/gen/idcard.png";
//public static final String outDir = "D:/gen/";
public static final String outPath = ".\\idcard.png";//这个是临时文件名
public static final String outDir = ".\\";
public static final String outSuf = ".jpg";
public static final int canvasWidth = 480;
public static final int canvasHeight = 320;
public static final int imgWidth = 270;
public static final int imgHeigth = 428;
public static final int xStart = 60;
public static final int yStart = 85;
public static final int yStep = 32;
public static final int xStep = 90;
public static final int charSpace = 10;
public static final int paramXStart = 110;
public static final int nationSpace = 140;
public static final int monthSpace = 120;
public static final int daySpace = 60;
public static final int idNoSpace = 80;
public static final int charLineSpace = 25;

public void paint();
}

2、IDCardInfo.java

public class IDCardInfo {
private String name = "";
private String sex = "";
private String nation = "";
private String bornYear = "";
private String bornMonth = "";
private String bornDay = "";
private String addr = "";
private String idNo = "";
private String expDate = "";
private String issuingAuthority = "";
private String addr1 = "";
private String addr2 = "";

public String getAddr1() {
addr1 = addr.length() > 11 ?
addr.substring(0,11) : "";
return addr1;
}

public String getAddr2() {
addr2 = addr.length() > 11 ?
addr.substring(11) : "";
return addr2;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getNation() {
return nation;
}
public void setNation(String nation) {
this.nation = nation;
}
public String getBornYear() {
return bornYear;
}
public void setBornYear(String bornYear) {
this.bornYear = bornYear;
}
public String getBornMonth() {
return bornMonth;
}
public void setBornMonth(String bornMonth) {
this.bornMonth = bornMonth;
}
public String getBornDay() {
return bornDay;
}
public void setBornDay(String bornDay) {
this.bornDay = bornDay;
}
public String getAddr() {
return addr;
}
public void setAddr(String addr) {
this.addr = addr;
}
public String getIdNo() {
return idNo;
}
public void setIdNo(String idNo) {
this.idNo = idNo;
}
public String getExpDate() {
return expDate;
}
public void setExpDate(String expDate) {
this.expDate = expDate;
}
public String getIssuingAuthority() {
return issuingAuthority;
}
public void setIssuingAuthority(String issuingAuthority) {
this.issuingAuthority = issuingAuthority;
}
}

4、TestGenCard.java(程序入口)

public class TestGenCard {
public static void main(String[] args) {
IDCardInfo idCard = new IDCardInfo();
idCard.setName("赵一鹏");
idCard.setSex("男");
idCard.setNation("汉");
idCard.setBornYear("1999");
idCard.setBornMonth("8");
idCard.setBornDay("8");
idCard.setAddr("陕西省渭南市大荔县黄河镇黄家沟二组");
idCard.setIdNo("622426199908080018");
try {
IDCardGeneratorFront idCardFront = new IDCardGeneratorFront(idCard);
idCardFront.paint();
System.out.println("complete!!!");
} catch (Exception e) {
e.printStackTrace();
}
}
}

执行方法：进入当前java文件目录，打开命令窗口，1、执行javac TestGenCard.java进行编译（若出现乱码，则执行javac -encoding utf-8 TestGenCard.java），2、java TestGenCard执行java文件运行成功
