聚合项目打war包，部署tomcat问题

日前做一个人脸识别的项目，框架搭建采用maven，springboot搭建，数据库使用sqlite数据库，对于这个数据库也是第一次用到，还有待研究，，，这次就说一个问题，聚合项目打war包问题，对于这个也是有点懵了。

首先项目是多模块聚合项目，其次使用springboot框架，打war包一直报错，说是找不到类包之类的，，控制台报错如下：

最后根据报错信息判断是少包依赖，，之后就是在主项目pom文件中比对。。。最后还是通过查看人人框架架构得知，对于聚合项目，除了父项目外，还有一个主项目，和公共模块，人人安全框架架构也整理了下，如下图：

renren-security
├─renren-common     公共模块
│ 
├─renren-admin      管理后台
│    ├─db  数据库SQL脚本
│    │ 
│    ├─modules  模块
│    │    ├─job 定时任务
│    │    ├─oss 文件存储
│    │    └─sys 系统管理(核心)
│    │ 
│    └─resources 
│        ├─mapper   MyBatis文件
│        ├─statics  静态资源
│        ├─template 系统页面
│        │    ├─modules      模块页面
│        │    ├─index.html   AdminLTE主题风格（默认主题）
│        │    └─index1.html  Layui主题风格
│        └─application.yml   全局配置文件
│       
│ 
├─renren-api        API服务
│ 
├─renren-generator  代码生成器
│        └─resources 
│           ├─mapper   MyBatis文件
│           ├─template 代码生成器模板（可增加或修改相应模板）
│           ├─application.yml    全局配置文件
│           └─generator.properties   代码生成器，配置文件
│

由此可以看出上面报的错就是缺少公共模块导致的，，之后就是查看如何引入已有项目jar包，，查了半天，刚开始以为是将common项目打包后放到主项目里就可以了，最后发现这样是没有用的。首先我在resources下新建lib文件夹，将common打jar包放到lib下，pom中添加如下依赖，然后开始maven clean ,maven install主项目，，发现又报错了，报错是引入那个依赖问题，

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>easyexcel</artifactId>
            <version>1.0.1</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/lib/face-common.jar</systemPath>

</dependency>

控制台报错信息如下：

这个问题纠结了老半天，，感觉搞不定了，，

最后同事通过看人人代码pom配置发现引入依赖写法错误，，于是我更改之前引入的代码，删除之前创建的lib文件夹以及jar文件，，，直接在主项目pom中添加common依赖，如下：

<dependency>
            <groupId>io.renren</groupId>
            <artifactId>face-common</artifactId>
            <version>3.2.0</version>
</dependency>

进行再次测试，终于ok了，就这一个打war包，搞了这么久，感觉头大，，

war包打好后就是放到tomcat下去部署，，部署之后发现，又出问题了，tomcat启动正常，项目启动正常，网页访问项目也正常，就是登陆时候一直显示“未知异常请联系管理员”，无法登录进去，，通过查看报错信息得知是无法访问到我的数据库，，这才考虑到是数据库访问路径出现bug了，尴尬！！！

报错信息如下：

通过以上报错信息，判断是不能访问到我的数据库，最后查看配置的数据库路径，，对于配置sqlite路径试了几种方法，如下图配置信息：

第一种和第三种都是无法访问的，最后在网上搜到sqlite数据库相对路径的配置，才得出第二种方法，，然后重新打war包进行部署测试，终于ok了，登进去了，到这里，这个打war包部署tomcat上就算结束了，有几个问题：

1.聚合项目如何体现这个聚合呢，仅仅只是添加模块的依赖吗？？

2.sqlite数据库与咱们一般使用的mysql数据库有什么差别呢，这个后期得了解下sqlite数据库了。

以上就是这次的问题，在此记录下，以免忘记。。。。。。

文中若有什么不妥之处请大家指正，大家一起学习成长。
