springboot maven多模块打包报dao模块mybatis mapper文件找不到，如何解决？

Question

现在项目有三个模块：dao(mybatis)模块、service模块和web模块，我在project 的pom.xml文件是这样打包设置的：

 <build>
        <finalName>good-learning-success</finalName>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <excludes>
                    <exclude>**/*.java</exclude>
                </excludes>
                <filtering>false</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
                <filtering>false</filtering>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <!-- 指定该Main Class为全局的唯一入口 -->
                    <mainClass>com.qtay.gls.Application</mainClass>
                    <layout>ZIP</layout>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal><!--可以把依赖的包都打包到生成的Jar包中-->
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

打包也成功了，本地运行更没问题，但是我上传到服务器运行的时候：java -jar xxx就报：

2017-12-09 11:49:42.196 INFO  [background-preinit] o.h.validator.internal.util.Version - HV000001: Hibernate Validator 5.3.5.Final

Answer 1

问题解决了：
解决方法是这样的，我把build相关配置从project 的pom.xml移到web module的pom.xml上面 再执行打包就ok了！

关键是project pom.xml和module pom.xml有什么区别吗，有人知道可以在下面回答探讨下

Answer 2

通过你给出的日志，我只能看出springboot启动时扫描不到dao层接口
我建议你在启动类里面加上mapper扫描注解，如@MapperScan("com.qtay.gls.dao")
