400错误 The server cannot or will not process the request due to something that is perceived to be a c

The server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).

由于被认为是客户端错误(例如,格式错误的请求语法、无效的请求消息帧或欺骗性的请求路由),服务器无法或将不会处理该请求。

注意:

如果你只写了有参构造方法(初始化成员变量),没有写无参构造,这是系统不会自动添加无参构造的,此时程序会报错。

无参构造一般是用来初始化:如为变量赋值处理,初始化对象等。
