公共模块Common

1.公共mapper.xml

• 其他模块的配置

mybatis:
  mapper-locations:  classpath*:org/example/common/web/mappers/*.xml
  typeAliasesPackage: org.example.common.web.domain

# mybatis-plus相关配置
mybatis-plus:
  # xml扫描，多个目录用逗号或者分号分隔（告诉 Mapper 所对应的 XML 文件位置）
  mapper-locations: classpath:org/example/common/web/mappers/*.xml

• 启动类

@MapperScan("org.example.common.web.dao")

• pom.xml
  前面没有解决找不到xml可以尝试

<build>
    <!--        解决找不到mapper.xml的问题-->
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <filtering>false</filtering>
            <includes>
                <include>**/mappers/*.xml</include>
            </includes>
        </resource>
    </resources>
</build>

## 2.打包配置
```xml
  <build>
      <!--最终打包的名字-->
      <finalName>${project.artifactId}</finalName>

      <resources>
          <resource>
              <directory>src/main/java</directory>
              <includes>
                  <include>**/*.xml</include>
              </includes>
          </resource>
          <resource>
              <directory>src/main/resources</directory>
          </resource>
      </resources>
