获取远程文件下载

1.下载aspose-words-15.8.0-jdk16.jar包链接：https://pan.baidu.com/s/1vJlZcIf_dzjFsyCVqGcw1Q提取码：iss02.代码package test;import java.awt.Color;import java.awt.Graphics2D;import java.awt.image.BufferedImage;import java.io.ByteArrayInputStream;impo..

public static <T> List<T> castList(Object obj, Class<T> clazz) { List<T> result = new ArrayList<T>(); if (obj instanceof List<?>) { for (Object o : (List<?>) obj) { r...

Class clazz = Class.forName("com.zhc.nly.service.merchants.MerchantsService");Object o = clazz.newInstance();Method method = clazz.getMethod("listShopProductBySel",String.class);Object object = method.invoke(o, shopWares.getWaresId());在Controller层通过.

最先出现这个问题我以为是我的jdk没有设置为1.8，但是在File >> Project Structure >> Project language level确实是8。依然是：Try-with-resources are not supported at language level '5’错误。后来更改pom.xml 中添加以下配置就好了：<build> <plugins> <plugin&g

pom.xml<dependency> <groupId>com.google.zxing</groupId> <artifactId>core</artifactId> <version>3.3.0</version></dependency><dependency> <groupId>com.google.zxing</groupId> <art

一、部分系统属性简介：前半部分是参数，后半部分是取出的值所代表的意义！这样说还是比较抽象，可以结合后面的实例以及输出结果来理解一下！java.version Java运行时环境版本java.vendorJava运行时环境供应商java.vendor.urlJava供应商的 URLjava.homeJava安装...

在web.xml 追加    disable_conf *.xml *.log *.dll
