Cannot deserialize instance of `java.lang.String` out of START_ARRAY token

记一次参数解析错误的解决.具体错误信息如下:

Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of `java.lang.String` out of START_ARRAY token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.lang.String` out of START_ARRAY token
 at [Source: (PushbackInputStream); line: 2, column: 7] (through reference chain: java.util.LinkedHashMap["id"])]

模拟案发现场如下:

于是乎,或者修改前台参数类型或者后台接收参数的类型,改正后示例如下:
