前言
主要使用了JEditorPane的setPage方法，本身支持的CSS样式有限，只适用于展示简单粗糙的html内容
正文
效果
java代码
package demo.html;
import javax.swing.*;
import java.awt.*;
import java.io.IOException;
import java.net.URL;
public class JEditorPaneLoadHtmlDemo {
public static void main(String[] args) throws IOException {
JFrame frame = new JFrame("一克金代码");
frame.setLocationRelativeTo(null);
frame.setSize(500,600);
JEditorPane editorPane = new JEditorPane();
editorPane.setLayout(new BorderLayout());
URL resource = JEditorPaneLoadHtmlDemo.class.getClass().getResource("/demo/html/test.html");
editorPane.setPage(resource);
frame.getContentPane().add(editorPane);
frame.setVisible(true);
}
}
html文件代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>Title</h1>
<ul>
<li>item1</li>
<li>item2</li>
<li>item1</li>
</ul>
</body>
</html>JEditorPane并不支持所有的css样式
根据javax.swing.text.html.CSS.java中的说明支持的CSS
* <ul><li>font-family
* <li>font-style
* <li>font-size (supports relative units)
* <li>font-weight
* <li>font
* <li>color
* <li>background-color (with the exception of transparent)
* <li>background-image
* <li>background-repeat
* <li>background-position
* <li>background
* <li>text-decoration (with the exception of blink and overline)
* <li>vertical-align (only sup and super)
* <li>text-align (justify is treated as center)
* <li>margin-top
* <li>margin-right
* <li>margin-bottom
* <li>margin-left
* <li>margin
* <li>padding-top
* <li>padding-right
* <li>padding-bottom
* <li>padding-left
* <li>padding
* <li>border-top-style
* <li>border-right-style
* <li>border-bottom-style
* <li>border-left-style
* <li>border-style (only supports inset, outset and none)
* <li>border-top-color
* <li>border-right-color
* <li>border-bottom-color
* <li>border-left-color
* <li>border-color
* <li>list-style-image
* <li>list-style-type
* <li>list-style-position
* </ul>列举但不支持的
列举了并不支持的
* <ul><li>font-variant
* <li>background-attachment (background always treated as scroll)
* <li>word-spacing
* <li>letter-spacing
* <li>text-indent
* <li>text-transform
* <li>line-height
* <li>border-top-width (this is used to indicate if a border should be used)
* <li>border-right-width
* <li>border-bottom-width
* <li>border-left-width
* <li>border-width
* <li>border-top
* <li>border-right
* <li>border-bottom
* <li>border-left
* <li>border
* <li>width
* <li>height
* <li>float
* <li>clear
* <li>display
* <li>white-space
* <li>list-style
* </ul>其他的CSS就更不支持了。
至此Swing使用JEditorPane加载显示本地的html文件以及支持的CSS样式内容完成。
