我之前一般都是把自己寫的本地包放到classmap里的；
前兩天看了一個(gè)視頻，比較標(biāo)準(zhǔn)的寫法是，放到psr-4里；

寫到這個(gè)里面之后，找不到類；

"autoload": {
        "classmap": [
            "database/seeds",
            "database/factories",
            "vendor/jormin/laravel-ddoc",
            "vendor/jormin/laravel-kdniao",
            "vendor/xdstack/ip2location",
            "vendor/overtrue/weather"
        ],
        "psr-4": {
            "App\\": "app/",
            "Jeffcott\\express\\": "packages/jeffcott/express/src",
            "Jeffcott\\clear\\": "packages/jeffcott/clear/src/",
            "Jeffcott\\Weather\\": "packages/jeffcott/weather/src",
            "Jeffcott\\chinese-calendar\\": "packages/jeffcott/chinese-calendar/src"
        }
    },

另外一個(gè)包：
