우리가 만들 것

이 예에서는 직원 목록을 만들고 보고서를 디자인한 다음 직원 목록을 보고서에 채웁니다. 마지막으로 PDF 보고서를 생성합니다.

따라야 할 단계

오류 없는 보고서를 생성하려면 다음 단계를 따라야 합니다.

1단계: 직원 목록을 만듭니다.

private List<Employee> empList = Arrays.asList(
		new Employee(1, "Sandeep", "Data Matrix", "Front-end Developer", 20000),
		new Employee(2, "Prince", "Genpact", "Consultant", 40000),
		new Employee(3, "Gaurav", "Silver Touch ", "Sr. Java Engineer", 47000),
		new Employee(4, "Abhinav", "Akal Info Sys", "CTO", 700000));

복사

2단계: Jaspersoft iReport Designer 도구 를 사용하여 디자인 한 보고서 .jrxml를 컴파일합니다 ..jasper

JasperReport jasperReport = JasperCompileManager.compileReport(reportPath + "\\employee-rpt.jrxml");

복사

3단계: 직원 목록을 에 전달 JRBeanCollectionDataSource합니다.

JRBeanCollectionDataSource jrBeanCollectionDataSource = new JRBeanCollectionDataSource(empList);

복사

4단계: 매개변수를 추가합니다( 선택사항 ).

Map<String, Object> parameters = new HashMap<>();
parameters.put("createdBy", "Websparrow.org");

복사

5단계: 를 호출하여 직원 및 매개변수 목록을 보고서에 입력합니다 JasperFillManager.fillReport().

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, jrBeanCollectionDataSource);

복사

6단계: 마지막으로 보고서를 PDF 파일로 내보냅니다.

JasperExportManager.exportReportToPdfFile(jasperPrint, reportPath + "\\Emp-Rpt.pdf");

복사

보고서 템플릿

보고서 디자인은 JRXML 파일에 정의됩니다.

직원-rpt.jrxml

모델 클래스

필드가 있는 간단한 Employee클래스를 만듭니다. 모든 필드 및 매개 변수가 있는 생성자의 Getters 및 Setters 메서드를 생성합니다.

Employee.java

package org.websparrow.report.dto;

public class Employee {

	// Generate Getters and Setters...
	private int id;
	private String name;
	private String oraganization;
	private String designation;
	private int salary;

	public Employee(int id, String name, String oraganization, String designation, int salary) {
		super();
		this.id = id;
		this.name = name;
		this.oraganization = oraganization;
		this.designation = designation;
		this.salary = salary;
	}
}

서비스 등급

서비스 클래스 내에서 위에서 언급한 모든 단계를 따릅니다. 서비스 클래스는 보고서를 제공할 책임이 있습니다.

EmployeeReportService.java

package org.websparrow.report.service;

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

			String reportPath = "F:\\Content\\Report";

			// Compile the Jasper report from .jrxml to .japser
			JasperReport jasperReport = JasperCompileManager.compileReport(reportPath + "\\employee-rpt.jrxml");

			// Get your data source
			JRBeanCollectionDataSource jrBeanCollectionDataSource = new JRBeanCollectionDataSource(empList);

			// Add parameters
			Map<String, Object> parameters = new HashMap<>();

			parameters.put("createdBy", "Websparrow.org");

			// Fill the report
			JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters,

그것을 실행

이 App클래스에는 기본 메서드가 포함되어 있으며 응용 프로그램을 시작합니다. 또한 EmployeeReportService서버 시작 시 클래스를 초기화하고 보고서를 생성합니다. 자세한 내용은 IDE의 콘솔 로그를 확인하세요.

앱.자바

package org.websparrow.report;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.websparrow.report.service.EmployeeReportService;

@SpringBootApplication
public class App {

	public static void main(String[] args) {
		SpringApplication.run(App.class, args);
	}

	@Bean
	public String generateReport(final EmployeeReportService employeeReportService) {

		String msg = employeeReportService.generateReport();

		System.out.println(msg);

		return msg;
	}
}

응용 프로그램이 웹 기반인 경우 컨트롤러 클래스를 통해서도 호출할 수 있습니다.

EmpReportController.java

package org.websparrow.report.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.websparrow.report.service.EmployeeReportService;

@RestController
@RequestMapping("/employee")
public class EmpReportController {

	@Autowired
	private EmployeeReportService employeeReportService;

	@GetMapping("/report")
	public String empReport() {

		return employeeReportService.generateReport();

직원 PDF 보고서 를 받으려면 웹 브라우저 에서 http :// localhost : 8080 / 직원 / 보고서 URL을 누르십시오. 마지막으로 지정된 위치에 대한 아래 보고서를 얻습니다.
