今天当我测试接口的时候发生了request对象的异常：
大概意思什么不能构建HttpServletRequest实例，缺少构造函数之类的
在这里插入图片描述
完整异常信息：

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `javax.servlet.http.HttpServletRequest` (no Creators, like default constructor, exist): 
	abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information
 at [Source: (org.springframework.util.StreamUtils$NonClosingInputStream); line: 1, column: 1]

后来发现是我在控制层的接口方法中的参数顺序写错了，

SO 个人理解：当接口既需要其他类型、引用类和HttpServeltRequest对象的时候，HttpServeltRequest不能作为第一个入参，不然就会报实例化异常

下面是错误代码：
在这里插入图片描述
把request放到后面就好了

具体为什么？我也不晓得,hh

在实体类user中只有userid，Uusername， Ppassword，role这四个属性都有get，set方法，但是其他方法有返回值，所以在序列化时，其他方法返回的值也会被序列化存在缓存中，此时不会出错，但是从缓存中反序列化时就因为有些值没有set方法，所以会出错。但有时会碰到必须要有有返回值的其他方法，例如在整合security时自定义登录认证和权限认证时需要继承UserDetail，就必须有其他方法，这时候可以RedisTemplate的设置里加。
