1.懒加载第一种情况

• 有时候需要使用多个子组件的时候我们就可以使用子组件懒加载
• 定义好所需要的子组件，在components中实现按需加载，也就是懒加载

const coms = {
		compSteps: resolve => {
			require(['@/pages/components/xxxx.vue'], resolve)
		},
		pInfo: resolve => {
			require(['@/pages/components/xxxx.vue'], resolve)
		},
		pForm: resolve => {
			require(['@/pages/components/xxx.vue'], resolve)
		},
		bisDialog: resolve => {
			require(['@/pages/components/xxx.vue'], resolve)
		},
	}
export default {
        components:coms
    }

2.懒加载第二种情况

• 也可以直接在conponents里面直接实现懒加载

expore default {
        components:{
   childrenComp:require(['@/pages/components/xxxx.vue'], resolve)
        }
    }
