mybatis-plus:
  mapper-locations: classpath*:org/jeecg/modules/**/xml/*Mapper.xml,classpath*:org/jeecg/modules/**/mapping/*Mapper.xml,classpath:/META-INF/modeler-mybatis-mappings/*.xml
  configuration-properties:
    prefix:
    blobType: BLOB
    boolValue: TRUE

需配置路径classpath:/META-INF/modeler-mybatis-mappings/*.xml，否则会扫描不到
还需配置configuration-properties中的属性，要不然就报错“Error parsing Mapper XML。。。。”
