1.拷贝必须的JAR包到项目的lib下。
commons-beanutils-1.7.jar
commons-collections-2.1.jar
commons-digester-1.7.jar
commons-javaflow-20060411.jar
commons-logging-1.0.2.jar
iReport.jar
itext-1.3.1.jar
iTextAsian.jar
jasperreports-2.0.5.jar
jdt-compiler-3.1.1.jar
poi-3.0.1-FINAL-20070705.jar
commons-beanutils-1.7.jar
commons-collections-2.1.jar
commons-digester-1.7.jar
commons-javaflow-20060411.jar
commons-logging-1.0.2.jar
iReport.jar
itext-1.3.1.jar
iTextAsian.jar
jasperreports-2.0.5.jar
jdt-compiler-3.1.1.jar
poi-3.0.1-FINAL-20070705.jar
2.新建一个目录,用来存放设计文件,jrxml文件。
3.新建一个目录,用来存放编译后的文件。
4.编译报表。
/**
* 编译报表
*/
public static void compiler(String sourceFileName, String destFileName) {
try {
JasperCompileManager.compileReportToFile(sourceFileName, destFileName);
} catch (JRException e) {
e.printStackTrace();
}
}
5.填充报表
/**
* 填充报表
*/
public static void fill(String sourceFileName, String destFileName) {
try {
JasperFillManager.fillReportToFile(sourceFileName, destFileName, new HashMap(), DataBaseManager.getConnection());
} catch (JRException e) {
e.printStackTrace();
}
}
6.导出HTML格式报表。
/**
* 导出HTML格式报表
*/
public static void exportToHTML(String sourceFileName,String destFileName) {
try {
JasperPrint jp = (JasperPrint) JRLoader.loadObject(sourceFileName);
JRHtmlExporter export = new JRHtmlExporter();
export.setParameter(JRExporterParameter.JASPER_PRINT, jp);
export.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFileName);
export.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, Boolean.FALSE);
export.exportReport();
} catch (JRException e) {
e.printStackTrace();
}
}
7.导出PDF格式报表。
public static void exportToPdf(String sourceFileName,String destFileName) {
try {
JasperPrint jp = (JasperPrint) JRLoader.loadObject(sourceFileName);
JRPdfExporter export = new JRPdfExporter();
export.setParameter(JRExporterParameter.JASPER_PRINT, jp);
export.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFileName);
export.exportReport();
} catch (JRException e) {
e.printStackTrace();
}
}
