若依+lodop+jasperreports+ireport 设计打印票据格式
一、设计表格
官网下载ireport5.6，解压安装，jdk 1.7适配ireport5.6，jdk1.8不适配
安装好jdk1.7(不用配置path，安装好就行)，进入ireport5.6安装目录，找到配置文件，配置jdk1.7安装路径
打开软件 选择a4 模板
添加参数studentList ，也就是java 绑定表格数据
选择Table 拖到页面上、表格对应的子数据设置·字段，也就是对应Java 传入studentList对象的属性
注意：属性名和字段类型必须对应
表格绑定studentList,设置数据类型是集合类型
选择数据类型为：new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{studentList})
保存文件
二、若依VUE前端
封装lodop.js
js
import request from "@/utils/request";
var CreatedOKLodop7766 = null
export function needCLodop() {
try {
var ua = navigator.userAgent
if (ua.match(/Windows\sPhone/i) != null) return true
if (ua.match(/iPhone|iPod/i) != null) return true
if (ua.match(/Android/i) != null) return true
if (ua.match(/Edge\D?\d+/i) != null) return true
var verTrident = ua.match(/Trident\D?\d+/i)
var verIE = ua.match(/MSIE\D?\d+/i)
var verOPR = ua.match(/OPR\D?\d+/i)
var verFF = ua.match(/Firefox\D?\d+/i)
var x64 = ua.match(/x64/i)
if (verTrident == null && verIE == null && x64 !== null) return true
else if (verFF !== null) {
verFF = verFF[0].match(/\d+/)
if (verFF[0] >= 41 || x64 !== null) return true
} else if (verOPR !== null) {
verOPR = verOPR[0].match(/\d+/)
if (verOPR[0] >= 32) return true
} else if (verTrident == null && verIE == null) {
var verChrome = ua.match(/Chrome\D?\d+/i)
if (verChrome !== null) {
verChrome = verChrome[0].match(/\d+/)
if (verChrome[0] >= 41) return true
}
}
return false
} catch (err) {
return true
}
}

},三、若依VUE后端
resource创建文件夹，把刚刚设计好的文件，修改文件内容
xml
language="groovy" 替换为 language="java" 
修改文件名与前端url 参数pages对应的值一样
然后放入resource创建的文件夹

}四、安装打印预览软件
CLodop_Setup_for_Win32NT与Lodop6.226_Clodop6.572
五、前端点击打印按钮
前端调用打印方法、电脑弹出预览页面
输出pdf
