所需依赖：
<dependency> <groupId>com.atlassian.commonmark</groupId> <artifactId>commonmark</artifactId> <version>0.11.0</version> </dependency>
代码示例：
import org.commonmark.node.Image;
import org.commonmark.node.Link;
import org.commonmark.node.Node;
import org.commonmark.parser.Parser;
import org.commonmark.renderer.html.AttributeProvider;
import org.commonmark.renderer.html.AttributeProviderContext;
import org.commonmark.renderer.html.AttributeProviderFactory;
import org.commonmark.renderer.html.HtmlRenderer;
import java.util.Map;
public class Md2Html { public static void main(String[] args){ Parser parser = Parser.builder().build();
Node document = parser.parse("```java\n" +
" // 根据 id 获取课程 \n" +
" @Override\n" +
" @GetMapping(\"/coursebase/get/{courseId}\")\n" +
" public CourseBase getCourseBaseById(@PathVariable(\"courseId\") String courseId) throws RuntimeException {\n" +
" return courseService.getCourseBaseById(courseId);\n" +
" }\n" +
"```");
HtmlRenderer renderer = HtmlRenderer.builder().
attributeProviderFactory(new AttributeProviderFactory() {
@Override
public AttributeProvider create(AttributeProviderContext attributeProviderContext) { return new AttributeProvider() {
// 自定义标签属性 可用单独类继承 AttributeProvider 接口
@Override
public void setAttributes(Node node, String s, Map<String, String> map) { if (node instanceof Image) { map.put("style", "width:150px;height:200px;position:relative;left:50%;margin-left:-100px;");
}
if (node instanceof Link) { map.put("target", "_blank");
}
}
};
}
}).
build();
/* lamada 改写
* HtmlRenderer renderer = HtmlRenderer.builder().
attributeProviderFactory(attributeProviderContext -> (node, s, map) -> { if (node instanceof Image) { map.put("style", "width:150px;height:200px;position:relative;left:50%;margin-left:-100px;");
}
if (node instanceof Link) { map.put("target", "_blank");
}
}).
build();
* */
String mdHtml = renderer.render(document);
mdHtml=mdHtml.replace("<pre>", "<pre class=\"fy-prettyprint linenums\">");
System.out.println(mdHtml);
}
}效果：
<pre class="fy-prettyprint linenums"><code class="language-java"> // 根据 id 获取课程
@Override
@GetMapping("/coursebase/get/{courseId}")
public CourseBase getCourseBaseById(@PathVariable("courseId") String courseId) throws RuntimeException { return courseService.getCourseBaseById(courseId);
}
</code></pre>
