}2.4 验证
2.4.1 调用登录接口 2.4.2 调用更新密码接口
二、SpringBoot项目部署 1、pom检查是否有打包插件 plugin groupIdorg.springframework.boot/groupId artifactIdspring-boot-maven-plugin/artifactId /plugin buildpluginsplugingroupIdorg.springframework.boot/groupIdartifactIdspring-boot-maven-plugin/artifactIdconfigurationimagebuilderpaketobuildpacks/builder-jammy-base:latest/builder/imageexcludesexcludegroupIdorg.projectlombok/groupIdartifactIdlombok/artifactId/exclude/excludes/configuration/plugin/plugins/build 2、打包 插曲 1、无效的标记: --release 这里要与你得jdk版本一致性 2、注意test当中的case 3、运行jar
java -jar SS.jar
4、测试 三、属性配置方式
1、命令参数方式 2、环境变量方式 3、外部配置文件方式 4、配置优先级 四、多环境开发-Profiles
1、多环境开发-介绍 2、 多环境开发-Profiles同一个yaml 3、多环境开发-Profiles(不同yml) 4、多环境开发-Profiles分组 分组实现
