1.在js文件中写入处理函数  

export default {
    methods: {
        /**
         * 面包屑处理函数
         * @param breadcrumbs 面包屑
         * @param component 需要加入进来的面包屑
         * @returns {Array}
         */
        dealCrumbs(breadcrumbs,component) {
            console.log("自定义函数");
            let newBreadcrumbs = [];
            if(breadcrumbs!=null && breadcrumbs.length>0){
                newBreadcrumbs =  _.filters(breadcrumbs,function (v) {
                    return v.component!==component.component;
                })
                newBreadcrumbs.push(component);
            }
            return newBreadcrumbs
        },
    }
}

2.在对应的vue文件中引用
