MyBatis使用别名

• 配置application.yml

mybatis:
  mapper-locations: classpath:/mybatis/mapper/*.xml
  type-aliases-package: com.zhaofeng.deliverymanagement.pojo
  configuration:
    map-underscore-to-camel-case: true
           

• 实体类没有getter和setter方法，可能会出现以下错误

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class com.zhaofeng.deliverymanagement.pojo.UserPojo and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com.zhaofeng.deliverymanagement.common.JsonResult["data"]->java.util.ArrayList[0])
           

• 为需要使用别名的实体类加上注解,如：

• xml文件中可以直接使用类名

<!-- 用户详细信息 -->
<resultMap id="UserDetailMap" type="UserPojo">
