本文介绍了Java用飞碟生成PDF的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用的罐子来自Maven 回购

The jar i am using is from the maven repo

我正在测试的代码来自以前的堆栈解决方案

The code i am testing is from a previous stack solution

我担心它可能会过时，因为库已过时.在测试以下代码时:

I fear it might be outdated because the libraries are depreciated. When testing the following code:

import java.io.ByteArrayInputStream;
import java.io.FileOutputStream;

import org.w3c.dom.Document;
import org.xhtmlrenderer.pdf.ITextRenderer;

public class test
{

    public static void main(String[] args)
    {
        ITextRenderer renderer = new ITextRenderer();

        // if you have html source in hand, use it to generate document object
        renderer.setDocumentFromString( "C:/Users/Goran/Documents/Documents/Development/workspace/FlyingSaucer/data/input/report.xhtml" );
        renderer.layout();

        String fileNameWithPath = "C:/Users/Goran/Documents/Documents/Development/workspace/FlyingSaucer/data/output/" + "PDF-FromHtmlString.pdf";
        FileOutputStream fos = new FileOutputStream( fileNameWithPath );
        renderer.createPDF( fos );
        fos.close();

        System.out.println( "File 2: '" + fileNameWithPath + "' created." );
    }

}

此行出现以下错误:renderer.createPDF( fos );

The type com.lowagie.text.DocumentException cannot be resolved. It is indirectly referenced from required .class files

任何人都可以对此有所了解，或提出用Java创建pdf文档的最佳方法吗?我同时有XML和XHTML文档.

Anyone able to shed some light on this, or suggest the best way to create a pdf document in java? I have both XML and XHTML documents available.

编辑当我从回购

Exception in thread "main" java.lang.NoClassDefFoundError: org/xhtmlrenderer/extend/UserAgentCallback
    at test.main(test.java:16)
Caused by: java.lang.ClassNotFoundException: org.xhtmlrenderer.extend.UserAgentCallback
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

我甚至还在使用正确的库/最新的库吗?

Am i even using the right libraries / the most up to date ones?

拥有最新资料库或知道其存储库的人可以链接它们吗?

Can someone who has the most recent libraries or know a repo where they are stored link them?

编辑2 放弃了使用飞碟并按建议使用ApacheFop的想法.当前错误是:

EDIT 2 Abandoned idea of using flying saucer and using ApacheFop as suggested. Current error is:

Mar 10, 2016 9:58:23 PM org.apache.fop.events.LoggingEventListener processEvent
WARNING: Font "Symbol,normal,700" not found. Substituting with "Symbol,normal,400".

推荐答案

我创建了一个具有以下依赖关系的简单Maven项目:

I created a simple Maven project with the following depencency:

    <dependency>
        <groupId>org.xhtmlrenderer</groupId>
        <artifactId>core-renderer</artifactId>
        <version>R8</version>
    </dependency>

我完全用您上面发布的代码创建了一个测试类，并且能够毫无问题地对其进行编译. Eclipse将其显示为Maven依赖项:

I created a test class with excatly the code that you posted above and was able to compile it without issue. This is what Eclipse shows as the Maven dependencies:

请注意，我必须更改此行才能使代码起作用:

Note that I had to change this line for the code to work:

renderer.setDocumentFromString("<html><body><strong>Hello</strong> <em>world</em>!</body></html>");

...，因为字符串本身应该是HTML内容，而不是文件的路径.

... since the string should be the HTML content itself any not the path to the file.

PDF看起来像这样:
