Jasperreport之与Springboot整合

环境：

jdk1.8

Jaspersoft Studio 6.5.0

Jasperreport 6.5.0

Springboot 1.5.x

 

一  用Jaspersoft Studio报表设计器设计一个报表test.jrxml

此处省略

 

二 整合springboot实现pdf预览报表数据 采用javabean数据方式

 

pom.xml增加

在src/main/resources下增加jasperreport文件夹 并将test.jrxml文件放入此处

 

控制器部分代码

访问可以看到实现了pdf预览，但是中文没有显示

 

可以在报表设计器设置对应字段元素属性

pdfFontName设置成"STSong-Light" 

pdfEncoding设置成"UniGB-UCS2-H" 

isPdfEmbedded设置成"true"

 

字段元素太多一个个设置 太麻烦 可以在test.jrxml文件统一设置默认属性

在property节点后面增加一行自定义样式

<style name="myStyle" isDefault="true" pdfFontName="STSong-Light" pdfEncoding="UniGB-UCS2-H" isPdfEmbedded="true"/>

 

 

再次拷贝该jrxml文件到项目中，重启应用再访问 可以看到显示了中文

 

附上test.jrxml内容

xml version="1.0" encoding="UTF-8"?>
