Question

我正在构建一个多模块Maven Web应用程序项目，但是我在Tomcat服务器上部署WAR时遇到了问题。

我的项目结构是

MyApp的
- MyAppSchemas
- MyAppUtils
- MyAppWs

这就是问题所在。当我尝试在我的本地Tomcat服务器上部署生成的war时，出现以下错误：

Apr 19, 2017 1:42:43 PM org.apache.catalina.core.StandardContext filterStart
SEVERE: Exception starting filter ApiOriginFilter
java.lang.ClassNotFoundException: io.swagger.api.ApiOriginFilter

APIOriginFilter是MyAppSchemas模块中生成的类。我已将MyAppSchemas jar包含在MyAppWs pom中作为依赖项：

结论：我如何在war运行时类路径中包含其他子模块？

Answer 1

这可以通过将您的类添加到外部jar并将其标记为依赖项来实现。

通过系统范围添加依赖关系

<dependency>
   ..
   <scope>system<scope>
   <systemPath>your jar path</systemPath>
</dependency>

然后使用下面的插件定义

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <includes>
                        <include>directory path/*.jar</include>
                    </includes>
                </configuration>
            </plugin>
        </plugins>
    </build>
