ruoyi vue 前後端分離版本 打包分離jar包至lib

HiEagle發表於2023-11-28
Vue後端JAR


環境：若依前後端分離版本，原打包時將所有的依賴jar包放至ruoyi-admin.jar 包中，該包130MB，過大。

需求：為了減少打包更新上傳的時間，減少至1.1mb

1、將不常更新的模組jar包分離至lib資料夾

2、將常更新的模組如common、system等打包至jar包中。

在ruoyi-admin的pom檔案中新增如下：

 

            <!--先去除所有的jar包-->
            <plugin>
                <groupId>org.springframework.boot</groupId>

                            <artifactId>nothing</artifactId>
                        </include>
 
                        <!--將需要的JAR包保留，如：專案中的 common、framework、system 等更新頻繁的模組-->
                        <include>

執行時會遇到一個問題：驗證碼無法顯示

Caused by: java.lang.ClassNotFoundException: com.ruoyi.common.config.kaptcha.KaptchaTextCreator

at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:581)

at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)

解決方案是重新編譯原google 的kaptcha原始碼，改動一下紅框標示之處

 

 

便於我使用,我直接將這個類 KaptchaTextCreator 放在了 common中,所以

// properties.setProperty(KAPTCHA_TEXTPRODUCER_IMPL, "com.google.code.kaptcha.text.impl.KaptchaTextCreator");
properties.setProperty(KAPTCHA_TEXTPRODUCER_IMPL, "com.ruoyi.common.config.kaptcha.KaptchaTextCreator");
