SpringBoot集成LayUI前端组件库（layui springboot）

boyanx8个月前 (04-28)技术教程35

现在大多数的WEB应用都是前后端分离，前端采用VUE,React等.但是今天我们介绍一个不用前后端分离的集成方案LayUI前端组件，作为纯后端开发我觉着上手还是挺简单的。

LayUI是一套开源的Web UI解决方案，采用自身经典的模块化规范，并遵循原生HTML/CSS/JS的开发方式，极易上手，拿来即用。LayUI提供了丰富的组件和样式，可以帮助开发者快速构建美观且响应式的Web界面。

LayUI官方文档：https://layui.dev/ 直接下载代码目录如下

将layui目录下的 css font layui.js 拷贝到应用中resources/static目录下

写个Controller

跳转到userForm.html

@RequestMapping("/userForm")
public ModelAndView userForm(Long userId) {
    logger.info("userForm controller");
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.addObject("userEntity", helloBiz.getUser(userId));
    modelAndView.setViewName("userForm");
    return modelAndView;
}

写个userForm.html

位置在
resources/templates/userForm.html

注意layui.css 和 layui.js 的引入路径；

变量的使用“用户标识”和“用户名称”，因为用了Thymeleaf模板。
