出错原因:把ASRConversionResponse内部类提出来,单独新建一个类ASRConversionResponse.java
3 我们看一下源代码，点击idea中异常信息：at org.apache.ibatis.executor.resultset.DefaultResultSetHandler.createByConstructorSignature(DefaultResultSetHandler.java:650)DefaultResultSetHandler的链接，跳到对应的源代码处。如下图 4 通过debug，确认Constructor[] arr$只有一个构造方法，就是我声明的。然后我们看...

The no-argument constructor, which is also a JavaBean convention, is a requirement for all persistent classes. Hibernate needs to create objects for you, using Java Reflection. 所有持久化类必须要求有不带参的构造方法(也是JavaBean的规范)。Hibernate需要使用Java反射为你创建对象。
例如Employee类中存在构造器Employee(String name, double salary, int y, int m, int d),那么e = new Employee()会报错。 Please keep in mind that you get a free no-argument constructoronlywhen your class has no other constructors. If you write your class with even a single constructor of you...
