简单的配置和使用。

/*
*该类一定是要public的,不要使用内部类
*/
public class Employee {
    private String name;
    private Date birthDate =new Date();
    private BigDecimal payment = new BigDecimal(23);
    private BigDecimal bonus =new BigDecimal(24);

    public Employee(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Date getBirthDate() {
        return birthDate;
    }

    public void setBirthDate(Date birthDate) {
        this.birthDate = birthDate;
    }

    public BigDecimal getPayment() {
        return payment;
    }

    public void setPayment(BigDecimal payment) {
        this.payment = payment;
    }

    public BigDecimal getBonus() {
        return bonus;
    }

    public void setBonus(BigDecimal bonus) {
        this.bonus = bonus;
    }
}


public static void main(String[] args) throws ParseException, IOException {

        InputStream is = new ExportManager().getTemplates("object_collection_template");
        List<Employee> employees = generateSampleEmployeeData();
        OutputStream os = new FileOutputStream("formulas_output.xlsx");
        Context context = new Context();
        context.putVar("employees", employees);
        JxlsHelper.getInstance().processTemplate(is, os, context);
    }

    public static List<Employee> generateSampleEmployeeData() throws ParseException {
        List<Employee> employees = new ArrayList<Employee>();
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MMM-dd", Locale.US);
        employees.add(new Employee("Elsa"));
        employees.add(new Employee("Oleg"));
        return employees;
    }


导出时候配置的模板如下,具体看自己的项目配置。


新手容易出现的问题:
1.导出路径找不到。自己找原因
2.导出时候只导出了模板,没有导出对应的数据【检查是否设置了area区域】
3.导出时候批注已经没有了,导出数据为空。【检查导出的对象是否是内部类】
4.导出时候excel说是格式不对,不能打开,【检查excel模板是否有多余的字符,不行就重新做一个模板】
