HTTP Status 500 - Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Error instantiating class com.airtechs.entity.order with invalid types (String,String,String,String,String,String,String,String,String,String,String,String,String,int,int) or values (ATS-1603010,辽宁海润环保,695000,徐建平,阿斯达,1111,222,333,444,555,666,777,null,null,null). Cause: java.lang.IllegalArgumentException
Error instantiating class com.airtechs.entity.order with invalid types (String,String,String,String,String,String,String,String,String,String,String,String,String,int,int) or values (ATS-1603010,辽宁海润环保,695000,徐建平,阿斯达,1111,222,333,444,555,666,777,null,null,null)
这段异常描述说明是实例化order类错误，报无效类型。你的类型是 (String,String,String,String,String,String,String,String,String,String,String,String,String,int,int)接收，但是你传的值是(ATS-1603010,辽宁海润环保,695000,徐建平,阿斯达,1111,222,333,444,555,666,777,null,null,null)，你自己看看这类型是不是不匹配。int类型怎么能接收到null，明显有问题了。
反射实体类异常，类型错误，最后两个参数int 尝试换成 Integer，int非对象类型！
