More and more chinese families consider sending kids oversea for better educatio

According a post I just read from Internet, more and more Chinese family would consider sending their children oversea for better education.


As we all know, education in China faces a lot of problems, like funding shortages, brainwashing, dominating and constrained way of teaching, disparities between urban and rural regions, and the limitations for children of migrant laborers .


According to the investigation, four out of five of Chinese young billionaires would consider sending their children overseas for better education. The number of Chinese undergraduates in the US has climbed 50% to 40,000, more than four times of the 2005 number.


One reason for this kind of situation is that wealth is climbing up in China , making overseas education more attainable for more and more families.


Yet the money is not the only reason, many parents are worrying about the quality of Chinese education .  Education system in China terribly relies on rote memorization and rigid testing , therefore, the Chinese students are not trained with analytical and creative thinking .


Many companies complain about Chinese university graduates: They cannot work independently, lack of social skills to work with a team, and they are too arrogant to learn new skills.


The quality of Chinese education is not only a problem for the elites, but also for ordinary families. Many parents who live in the city are immigrants from their home town. Their kids cannot get educated in the school of the city if they don’t have the city’s residence permit(HUKOU). Even if their kids can, the kids have to get back to their parents’ home town to take the college entrance exam due to Chinese HUKOU policy .


Another consideration for the ordinary families who consider sending their kids overseas for better education is that after their kids are graduated, their kids would have a good chance to migrant to the country for better living environment, better freedom, democracy and human rights.

 

They don’t need to worry about the food quality, environment pollution and the corruption of dictatorial government.


Above all, the reasons for parents sending their kids overseas for better education are mainly because:
1. Chinese wealth grows.
2. For better quality of education.
3. The good chance to migrant


Now if you have the opportunity to send your kids overseas for their education, what will you do?

 

内容概要:本文档是一份关于交换路由配置的学习笔记,系统地介绍了网络设备的远程管理、交换机与路由器的核心配置技术。内容涵盖Telnet、SSH、Console三种远程控制方式的配置方法;详细讲解了VLAN划分原理及Access、Trunk、Hybrid端口的工作机制,以及端口镜像、端口汇聚、端口隔离等交换技术;深入解析了STP、MSTP、RSTP生成树协议的作用与配置步骤;在路由部分,涵盖了IP地址配置、DHCP服务部署(接口池与全局池)、NAT转换(静态与动态)、静态路由、RIP与OSPF动态路由协议的配置,并介绍了策略路由和ACL访问控制列表的应用;最后简要说明了华为防火墙的安全区域划分与基本安全策略配置。; 适合人群:具备一定网络基础知识,从事网络工程、运维或相关技术岗位1-3年的技术人员,以及准备参加HCIA/CCNA等认证考试的学习者。; 使用场景及目标:①掌握企业网络中常见的交换与路由配置技能,提升实际操作能力;②理解VLAN、STP、OSPF、NAT、ACL等核心技术原理并能独立完成中小型网络搭建与调试;③通过命令示例熟悉华为设备CLI配置逻辑,为项目实施和故障排查提供参考。; 阅读建议:此笔记以实用配置为主,建议结合模拟器(如eNSP或Packet Tracer)动手实践每一条命令,对照拓扑理解数据流向,重点关注VLAN间通信、路由选择机制、安全策略控制等关键环节,并注意不同设备型号间的命令差异。
<think>我们正在解决JasperReports中出现的字体不可用问题,具体错误是:`net.sf.jasperreports.engine.util.JRFontNotFoundException:Font‘宋体’isnotavailabletotheJVM`。根据引用[1][2][3]可知,这是因为JVM没有找到指定的字体(如宋体、楷体)。下面提供几种解决方案:###解决方案概览1.**确保字体已安装到操作系统**(基础步骤)2.**在JasperReports中注册字体**(代码级解决)3.**使用字体扩展(JAR)**(推荐方式)4.**配置JVM字体路径**(系统级解决)###详细步骤####方法1:确保操作系统已安装字体(Windows示例)1.将字体文件(如`simsun.ttf`)复制到`C:\Windows\Fonts`2.重启应用服务器(确保JVM重新加载字体)>注意:如果使用Docker容器,需要将字体挂载到容器内并安装。####方法2:代码中动态注册字体(推荐灵活方案)```javaimportjava.awt.Font;importnet.sf.jasperreports.engine.util.JRFontNotFoundException;publicclassFontRegister{publicstaticvoidregisterFont(StringfontPath){try{//加载字体文件Fontfont=Font.createFont(Font.TRUETYPE_FONT,newFile(fontPath));//注册到GraphicsEnvironmentGraphicsEnvironmentge=GraphicsEnvironment.getLocalGraphicsEnvironment();ge.registerFont(font);System.out.println("字体注册成功:"+font.getName());}catch(Exceptione){thrownewJRFontNotFoundException("字体注册失败:"+fontPath,e);}}}//在生成PDF前调用FontRegister.registerFont("C:/fonts/simsun.ttf");//绝对路径```####方法3:创建JasperReports字体扩展包(企业级方案)1.准备字体文件(如`simsun.ttf`)2.创建`fontsfamily.xml`:```xml<fontFamilies><fontFamilyname="SongTi"><normal>fonts/simsun.ttf</normal><bold>fonts/simsunbd.ttf</bold><italic>fonts/simsuni.ttf</italic><boldItalic>fonts/simsunbi.ttf</boldItalic></fontFamily></fontFamilies>```3.打包为JAR:```fonts.jar├──META-INF│└──fontsfamily.xml└──fonts├──simsun.ttf├──simsunbd.ttf└──...```4.将JAR放入项目类路径####方法4:配置JVM字体路径(适合服务器环境)在启动脚本中添加字体路径:```bashjava-Djava.awt.headless=true-Djava.awt.fonts=/path/to/fonts/-jaryour_app.jar```###验证字体是否可用```javaimportjava.awt.GraphicsEnvironment;publicclassCheckFonts{publicstaticvoidmain(String[]args){String[]fonts=GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();for(Stringfont:fonts){System.out.println(font);}}}```运行后检查输出中是否包含所需字体(如“宋体”)。###在JasperReports模板中使用字体`.jrxml`文件中指定:```xml<textField><textElement><fontfontName="SongTi"pdfFontName="fonts/simsun.ttf"pdfEncoding="Identity-H"isPdfEmbedded="true"/></textElement></textField>```###常见问题排查表|问题现象|解决方案||--------------------------|------------------------------||开发环境正常,生产环境报错|确保生产服务器安装了相同字体||字体注册后仍报错|检查字体路径权限是否正确||中文部分显示乱码|确认PDF配置了`Identity-H`编码|>技术原理:JasperReports生成PDF时依赖`itext`库渲染文本,而`itext`需要明确字体文件位置[^3]。###相关问题1.如何在Docker容器中为Java应用安装字体?2.JasperReports导出Excel时字体失效怎么办?3.如何为JasperReports报表动态切换中英文字体?</think>### 解决 Java JasperReports 中字体不可用的问题 当出现 `Font 'xx字体' is not available to the JVM` 错误时,说明 JVM 无法访问所需字体。以下是 **5 种解决方案**,按推荐顺序排列: --- ### ✅ 方案 1:代码中动态注册字体(最灵活可靠) ```java import java.awt.Font; import java.awt.GraphicsEnvironment; import java.io.File; public class FontLoader { public static void registerFont(String fontPath) { try { // 加载字体文件 Font font = Font.createFont(Font.TRUETYPE_FONT, new File(fontPath)); // 注册到 JVM GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); ge.registerFont(font); System.out.println("✅ 字体注册成功: " + font.getFontName()); } catch (Exception e) { throw new RuntimeException("❌ 字体注册失败: " + fontPath, e); } } } // 在生成 PDF 前调用(只需执行一次) FontLoader.registerFont("C:/fonts/simsun.ttf"); // 替换为实际字体路径 ``` --- ### ✅ 方案 2:配置 JasperReports 字体扩展(推荐生产环境) 1. **创建字体包**: ``` myfonts.jar ├── META-INF │ └── fonts.xml └── fonts ├── simsun.ttf # 宋体常规 ├── simsunbd.ttf # 宋体加粗 └── simsunbi.ttf # 宋体斜体 ``` 2. `fonts.xml` 配置: ```xml <fontFamilies> <fontFamily name="宋体"> <normal>fonts/simsun.ttf</normal> <bold>fonts/simsunbd.ttf</bold> <italic>fonts/simsuni.ttf</italic> <boldItalic>fonts/simsunbi.ttf</boldItalic> </fontFamily> </fontFamilies> ``` 3. 将 JAR 放入项目类路径 --- ### ✅ 方案 3:系统级字体安装(适合本地开发) 1. **Windows 安装字体**: - 复制 `.ttf` 文件到 `C:\Windows\Fonts` - 重启应用服务器 2. **Linux 安装字体**: ```bash mkdir /usr/share/fonts/custom cp *.ttf /usr/share/fonts/custom/ fc-cache -fv ``` --- ### ✅ 方案 4:JVM 启动参数指定字体路径 ```bash java -Djava.awt.headless=true \ -Djava.awt.fonts=/path/to/fonts/ \ -jar your_app.jar ``` --- ### ✅ 方案 5:强制指定 PDF 字体(临时方案) ```java // 在导出 PDF 前设置 System.setProperty("net.sf.jasperreports.default.font.name", "宋体"); System.setProperty("net.sf.jasperreports.default.pdf.font.name", "STSong-Light"); System.setProperty("net.sf.jasperreports.default.pdf.encoding", "UniGB-UCS2-H"); ``` --- ### 📝 验证字体是否生效 ```java // 检查已注册字体 String[] fonts = GraphicsEnvironment.getLocalGraphicsEnvironment() .getAvailableFontFamilyNames(); Arrays.stream(fonts).forEach(System.out::println); ``` --- ### 常见问题解决表 | 问题现象 | 解决方案 | |---------------------------|-----------------------------------| | 开发环境正常,生产环境报错 | 方案 2(字体扩展包) | | Docker 容器中报错 | 方案 1 + 镜像中安装字体 | | 部分中文显示方块 | 检查是否缺少粗体/斜体变体文件[^3] | | Linux 系统无中文字体 | 安装 `wqy-zenhei` 等字体包 | > **技术原理**:JasperReports 通过 `itext` 渲染 PDF 时,需要精确的字体文件路径和编码配置。动态注册确保字体被加载到 JVM 字体上下文中[^3]。 --- ### 📚 相关问题 1. 如何在 Docker 镜像中为 Java 应用安装中文字体? 2.
