java - 如何在对 Spring Boot Controller 的 GET 请求中接受 LocalDateTime 参数？

Question

这个问题与this SO problem非常相似适用于较早的 Date API。

我想用 Java 8 LocalDateTime API 实现同样的效果。当我这样做时，

@RequestMapping("/locationSnapshot/{userId}/{pointInTime}")
public MyResponse getLocationInTime(
        @PathParam(value="userId") Long userId,
        @PathParam(value="pointInTime")
        @DateTimeFormat(pattern="yyyy-MM-dd'T'HH:mm:ss") LocalDateTime pointInTime) {

    MyResponse response = new MyResponse();
    return response;
}

我明白了，

Failed to instantiate [java.time.LocalDateTime]: No default constructor
found; nested exception is java.lang.NoSuchMethodException: 
java.time.LocalDateTime.<init>()

Answer 1

使用@PathVariable 代替@PathParam

@RequestMapping("/locationSnapshot/{userId}/{pointInTime}")
public MyResponse getLocationInTime(
        @PathVariable(value="userId") Long userId,
        @PathVariable(value="pointInTime")
        @DateTimeFormat(pattern="yyyy-MM-dd'T'HH:mm:ss") LocalDateTime pointInTime) {

    MyResponse response = new MyResponse();
    return response;
}
