Java Maven构建成功，但仍然未找到404错误

因此，我正在尝试执行该指南，并通过在目标选项中使用clean install执行“runas”“maven build”来安装maven项目。我想不出是什么问题。我还使用m2e插件来运行maven构建，因为我搜索了其他人的答案，人们说使用EclipseMaven命令行很糟糕

但我在broswer中发现了这个错误

HTTP状态404–未找到 类型状态报告

除了maven build之外，运行启动应用程序的spring boot应用程序类。在项目级别的命令下运行

mvn spring-boot:run

如果您使用任何IDE，右键单击SpringBoot应用程序类并调用“运行应用程序”

这回答了你的问题吗？
