iReport工具的使用（二）

用JavaBean作为数据源开发报表

1、 创建DataBean，报表数据的每一个字段将对应该DataDean对象的一个属性

package direction.shoufei.report.groupyearfee.data;

public class CenterYearFee {
    private String centerId;
    private String centerName;
    private String queryYear;
    private double summary;
    private double preYearsummary;
    private double preYearRate;
    private double month1Fee;
    private double month2Fee;
    private double month3Fee;
    ...
    
    public String getCenterId() {
        return centerId;
    }
    public void setCenterId(String centerId) {
        this.centerId = centerId;
    }
    public String getCenterName() {
        return centerName;
    }
    public void setCenterName(String centerName) {
        this.centerName = centerName;
    }
    public String getQueryYear() {
        return queryYear;
    }
    public void setQueryYear(String queryYear) {
        this.queryYear = queryYear;
    }
    public double getSummary() {
        return summary;
    }
    public void setSummary(double summary) {
        this.summary = month1Fee + month2Fee + month3Fee + month4Fee
                + month5Fee + month6Fee + month7Fee + month8Fee + month9Fee
                + month10Fee + month11Fee + month12Fee;
    }  
    public double getPreYearsummary() {
        return preYearsummary;
    }
    public void setPreYearsummary(double preYearsummary) {
        this.preYearsummary = preYearsummary;
    }
    public double getPreYearRate() {
        return preYearRate;
    }
    public void setPreYearRate(double preYearRate) {
        this.preYearRate = preYearRate;
    }
    public double getMonth1Fee() {
        return month1Fee;
    }
    public void setMonth1Fee(double month1Fee) {
        this.month1Fee = month1Fee;
    }
    public double getMonth2Fee() {
        return month2Fee;
    }
    public void setMonth2Fee(double month2Fee) {
        this.month2Fee = month2Fee;
    }
    public double getMonth3Fee() {
        return month3Fee;
    }
    public void setMonth3Fee(double month3Fee) {
        this.month3Fee = month3Fee;
    }
    ...
} 

 

2、 设置类路径

3、 在iReport报表设计界面添加DataBean源字段

 

3、 用拖拽的方式将字段添加到Band（即Detail，columnHeader，columnFooter……），并且格式化报表

 

截止这里，报表的设计已完成。

下一步需要将报表展现的数据封装成一个List<DataBean>的对象。
