ClassNotFound Maven War

Question

我正在構建一個多模塊Maven web應用程序項目，但我在Tomcat服務器上部署WAR時遇到問題。

我的項目結構是

• MyApp的
  • MyAppSchemas
  • MyAppUtils
  • MyAppWs

這裏的問題。當我嘗試部署我的本地Tomcat服務器上生成我的戰爭，我得到以下錯誤：

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模塊中產生的一類。我已經包括了MyAppSchemas罐子作爲MyAppWs POM的依賴關係：

      </plugin> 
     </plugins> 
    </build> 
    <dependencies> 
     <dependency> 
      <groupId>io.swagger</groupId> 
      <artifactId>MyAppSchemas</artifactId> 
      <version>1.0</version> 
     </dependency> 
     <dependency> 
      <groupId>io.swagger</groupId> 
      <artifactId>MyAppUtils</artifactId> 
      <version>1.0</version> 
     </dependency> 
    </dependencies> 
</project> 

底線：我怎麼有我的戰爭運行時類路徑等子模塊？

Answer 1

這可以通過將您的類添加到外部jar並將其標記爲依賴來實現。

通過系統範圍添加的依賴

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

使用插件如下

<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>
