struts + jasperreporters

1.jasperreporters+ireport,版本要对应,先用ireport制作相应模版,生成相应.jasper文件。

实例如下：

2.jar包：

3.实体类

package com.pxj.report.pojo;

public class Address {
    private String city;
    private String zipcode;
    public String getCity() {
        return city;
    }
    public void setCity(String city) {
        this.city = city;
    }
    public String getZipcode() {
        return zipcode;
    }
    public void setZipcode(String zipcode) {
        this.zipcode = zipcode;
    }

}

package com.pxj.report.pojo;

import java.util.HashSet;
import java.util.Set;

public class Company implements Comparable<Company>{

    private String name;
    private Address address;
    private Set<Staff> staffs = new HashSet<Staff>();

    public String getName() {
        return name;
    }

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

    public Address getAddress() {
        return address;
    }

    public void setAddress(Address address) {
        this.address = address;
    }

    public Set<Staff> getStaffs() {
        return staffs;
    }

    public void setStaffs(Set<Staff> staffs) {
        this.staffs = staffs;
    }

    public int compareTo(Company o) {
        return o.getName().compareTo(this.getName());
    }

}

package com.pxj.report.pojo;

public class Staff {
    private String name;
    private Company company;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Company getCompany() {
        return company;
    }
    public void setCompany(Company company) {
        this.company = company;
    }

}

4.Action

package com.pxj.report.action;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import com.opensymphony.xwork2.ActionSupport;
import com.pxj.report.pojo.Address;
import com.pxj.report.pojo.Company;
import com.pxj.report.pojo.Staff;

public class DemoAction extends ActionSupport{
    private static final long serialVersionUID = 1446363L;

    private List<Staff> list;
    Map<String,Object> map;

    public List<Staff> getList() {
        return list;
    }

    public void setList(List<Staff> list) {
        this.list = list;
    }

    public Map<String, Object> getMap() {
        return map;
    }

    public void setMap(Map<String, Object> map) {
        this.map = map;
    }

    @Override
    public String execute() throws Exception {
        list = getData();
        map = getParameter();
        return super.execute();
    }

    private Map<String, Object> getParameter() {
        Map<String,Object> map = new HashMap<String,Object>();
        map.put("date", "2014-08-04");
        return map;
    }

    private List<Staff> getData() {
        Address addr = new Address();
        addr.setCity("重庆");
        addr.setZipcode("20140804");

        Company company1 = new Company();
        company1.setName("天友");
        company1.setAddress(addr);
        Company company2 = new Company();
        company2.setName("谷歌");
        company2.setAddress(addr);

        Staff staff1 = new Staff();
        staff1.setName("张三");
        staff1.setCompany(company1);
        Staff staff2 = new Staff();
        staff2.setName("李四");
        staff2.setCompany(company2);
        Staff staff3 = new Staff();
        staff3.setName("王五");
        staff3.setCompany(company1);

        List<Staff> list = new ArrayList<Staff>();
        list.add(staff1);
        list.add(staff2);
        list.add(staff3);
        return list;
    }
}
