对于小型项目没有必要左前后端分离，但又不想暴露前端代码，则需把vue打包后的代码整合到springboot

环境：

• JDK1.8
• springboot 2.3.4.RELEASE
• vue 2.6.11、vue-router 3.2.0、vue-cli 4.2.2

properties

server.port=8088

spring.resources.static-locations=classpath:public/,classpath:static/,file:public/,file:static/

vue.config.js

//注意要用绝对路径
publicPath: process.env.NODE_ENV === "production" ? "/" : "/",
    
outputDir: 'dist',
    
assetsDir: '',

前端编译打包之后直接将dist包下的的文件复制到springboot resources/static目录下

创建过滤器

@Order(1)
@WebFilter(urlPatterns = {"/*"}, filterName = "routerFilter")
public class RouterFilter implements Filter {

    @Override
    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) req;
        String servletPath = request.getServletPath();
        String context = request.getContextPath();
        //静态资源和接口一律放行
        if (servletPath.matches("^.*(.js|.css|.font|.svg|.woff|.ttf|.ico)$") || servletPath.startsWith("/v1")) {
            chain.doFilter(req, resp);
        } else {//路由地址一律转发到index.html页面
            req.getRequestDispatcher(context + "/index.html").forward(req, resp);
        }
    }

}

如果vue配置了基础路由

export default new VueRouter({
    mode: 'history',
    base: '/ui',
    routes
})

那么过滤器的判断可以简写成：

//路由地址一律转发到index.html页面
if (servletPath.startsWith("/ui")) {
    req.getRequestDispatcher(context + "/index.html").forward(req, resp);
} else {
    chain.doFilter(req, resp);
}

另外需要在启动类加@ServletComponentScan注解扫描到@WebFliter标记的过滤器

最后列几个打包编译、并复制编译后的文件到java项目中的插件，不做详细介绍
