依照docusaurus官网的文档，在`docusaurus.config.js`修改`additionalLanguages`就能为代码高亮增加更多语言支持,
PrimJs也确实支持Java，但是不知什么原因导致一些语言在docusaurus仍然无法支持，推测是这个版本导入依赖时有问题，有些语言的格式化代码没有引入，但是更新docusaurus不太现实。文档中给出了一种手动增加受支持语言的办法，可以通过`npm
run swizzle @docusaurus/theme-classic
prism-include-languages`将导入其他语言的功能模块文件手动导出再进行修改。这个文件本身是根据`additionalLanguages`设置再导入其他语言的格式，内容如下
```js
import siteConfig from '@generated/docusaurus.config';
export default function prismIncludeLanguages(PrismObject) {
const {
themeConfig: {prism},
} = siteConfig;
const {additionalLanguages} = prism;
// Prism components work on the Prism instance on the window, while prism-
// react-renderer uses its own Prism instance. We temporarily mount the
// instance onto window, import components to enhance it, then remove it to
// avoid polluting global namespace.
// You can mutate PrismObject: registering plugins, deleting languages...
As
// long as you don't re-assign it
globalThis.Prism = PrismObject;
additionalLanguages.forEach((lang) => {
// eslint-disable-next-line global-require, import/no-dynamic-require
require(`prismjs/components/prism-${lang}`);
});
delete globalThis.Prism;
}
```
但是手动导出的文件需要手动引入prismjs模块依赖，为了简洁改为直接将`prism-java.js`添加再导入，方法略微有些dirty但是至少可用。
