Question

我的API应用程序不允许使用此日期时间格式，后跟+0000

我试图通过代码对其进行格式化

import java.text.SimpleDateFormat

def pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
def input = "2019-02-28T02:54:32.123Z"
def date = new SimpleDateFormat(pattern).parse(input)

created(date)

但仍能得到结果

...
    "created": "2019-02-28T09:54:32+0000",
...

我如何以这种格式输出

...
    "created": "2019-02-28T09:54:32.123Z",
...

更新后的注释说明您正在生成JSON，我建议这可能是Why does Date serialize for a JSON key differently than it does for a JSON value?的副本

基本上，您正在尝试自定义日期的输出格式。如果要这样做，可以：

import java.util.Date
import java.text.SimpleDateFormat 
import groovy.json.JsonBuilder

def pattern = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" 
def input = "2019-02-28T02:54:32.123Z"   
def date = new SimpleDateFormat(pattern).parse(input)

// everything above here is from your original question

def pattern2 = "yyyy-MM-dd'T'HH:mm:ss'Z'" 
def sdf = new SimpleDateFormat(pattern2) 
sdf.setTimeZone(TimeZone.getTimeZone("GMT"))
def builder = new JsonBuilder()

builder {
  "created"(sdf.format(date))
}

终于解决了

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'")
String date = sdf.format(new Date())
