我的spring boot + mybatis项目在idea里面执行正常，但发布测试环境打成可执行jar包后就启动失败，提示错误如下：
[ ERROR] [2018-08-30 17:23:48] org.springframework.boot.SpringApplication [845] - Application run failed org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bookingController': Unsatisfied dependency expressed through field 'service'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bookingService': Unsatisfied dependency expressed through field 'mapper'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'citiesMapper' defined in URL [jar:file:/D:/Code/YSL_TravelSupport_CodeSource

[com/ysl/ts/core/service/hotel/config/HotelMybatisPlusConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'class path resource [mapper/ts_hotel_order/HotelRefundMoneyTaskMapper.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML. The XML location is 'class path resource [mapper/ts_hotel_order/HotelRefundMoneyTaskMapper.xml]'.
Cause: org.apache.ibatis.builder.BuilderException: Error resolving class. Cause: org.apache.ibatis.type.TypeException: Could not resolve type alias 'HotelOrdersModel'.
Cause: java.lang.ClassNotFoundException: Cannot find class: HotelOrdersModel
最后有一句写着：Cannot find class: HotelOrdersModel 找不到HotelOrdersModel类，打开这个mapper xml看到这里类在一个sql的resultType属性中使用
<select id="find" resultType="HotelOrdersModel">
这里不应该只写类名，而应该写全完整类名，就是包含包名的类名
<select id="find" resultType="com.ysl.ts.core.model.hotel.ts_hotel_order.HotelOrdersModel">
这样修改完成后再打包发布执行就解决了。
