SpringBoot：运行多模块项目

韩明德
2023-03-14

我有一个基本的SpringBoot应用程序。使用Spring初始值设定项、嵌入式Tomcat、Thymeleaf模板引擎，并将包作为可执行的JAR文件。是一个带有Spring Boot的多模块项目，该项目将有3个模块。这里是父模块pom。xml

从父根目录，我使用以下方法生成所有模块：

mvn clean package

但问题是tdk-web-0.0.2-SNAPSHOT。jar不包含tdk-core-0.0.2-SNAPSHOT。jar，然后在启动时失败

下面是maven的结果：

我解压缩了jar，没有核心模块的类

我有下一个错误：错误解析模板/tdk/login/login”，模板可能不存在，或者任何配置的模板资源都无法访问模板

我认为您的@ComponentScan注释丢失了，或者可能是错误的。（例如：@ComponentScan（{“com.tdkcloud.web”}）在com中找不到服务。TDK云。后端软件包）。或者，您的EmailService中可能缺少@Service annotation。

所以要解决这个问题，您的代码需要如下所示：

应用程序。java（或Webconfig.java）

@Configuration
@EnableWebMvc
@ComponentScan({"com.tdkcloud"})
@SpringBootApplication
public class App {
   ...
}

电子邮件服务。Java语言

public interface EmailService {
   ...
}

EmailServiceImpl。Java语言

@Service
public class EmailServiceImpl {
   ...
}

最近，我尝试将我的项目结构/布局之一实现为maven多模块项目。

我遵循了下面的spring指南链接，希望这将帮助您和其他官方spring多模块项目链接

  • 运行多模块Maven项目

    问题内容： 这是一个基本问题，我只是不太熟悉Maven多模块结构。说，我有一个Web应用程序。我想将一些模块连接到它（某些服务）。我是否需要仅将其中一个模块（依赖于其他模块）制作为一个Web应用程序，然后运行它？一开始我以为我可以运行整个项目，但是这个选项在我的IDE中是无效的（我现在正在使用NetBeans），这使我认为我应该运行一个类似于主模块的东西（在这种情况下为Web应用程序） ）。是这样
