Spring Boot 应用程序 - Tomcat 部署答案

【问题描述】：

我在将 Spring Boot 应用程序部署到 tomcat 时遇到问题，尽管在我的 IDE 中运行良好。我按照https://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html的指示进行操作

但结果我得到了一个仅包含框架库和 Web 类的 war 包，我的核心模块中没有任何内容。

我不确定我的 pom 文件是否正确。

我的项目结构如下：

portal  
   -web 
     -src
     pom1.xml
   -core  
     -src  
     pom2.xml  
pom0.xml

项目 pom (pom0.xml):

<modules>
    <module>core</module>  
    <module>web</module>
    <module>tests</module>
</modules>
<packaging>pom</packaging>

    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

</properties>

<build>

            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

web 模块 pom (pom1.xml):

 <parent>

        <artifactId>spring-boot-starter-tomcat</artifactId>

    </dependency>
</dependencies>

核心模块 pom (pom2.xml)

    <artifactId>portal</artifactId>

更新1

更详细的结构：

-web  
  -com.portal.web 
   -controller  
    IncidentController  
    ComputerController
    ...  
-core  
 -com.portal.core  
   -domain  
    Incident  
    Computer  
    ...

mvn clear package 给出了这个错误：

[INFO] portal ............................................. SUCCESS [  0.700 s]  
[INFO] core ............................................... SUCCESS [  2.478 s]  
[INFO] web ................................................ FAILURE [  0.458 s]  
[INFO] tests .............................................. SKIPPED  
...

【问题讨论】：

标签： maven tomcat spring-boot web-deployment

【解决方案1】：

将“web 模块”添加到父“门户模块”的模块部分：

<modules>
  <module>core</module>
  <module>api</module>
  <module>tests</module>
  <module>web</module>
</modules>

在父“门户模块”的文件夹中运行mvn clean package。

【讨论】：

感谢您的回答。那是一个错字，模块 web 存在于父文件夹的模块中。我更新了执行 mvn clean package 后出现的错误问题。

【解决方案2】：

多模块项目的解决方案是配置Boot的repackaging为jar应用分类器：

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <classifier>exec</classifier>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
