spring boot 请求中包含数组参数
一开始接口定义成这样

public ApiResult creMission(@RequestBody Mission mission,@RequestParam Integer[] copyIDs)

请求参数是这样

{
    "missionTitle": "新增任务测试",
    "missionContent": "任务内容",
    "missionType": "1",
    "etc": "2018-10-01 18:30:00",
    "missionScore": "5",
    "executerID": "3",
    "deptID": "2",
    "mangerID": "2",
    "remake": "",
    "explain": "分值是5分，抄送刘光宗、李四",
    "copyIDs": [
        1,
        11
    ]
}

结果就这样了……

Required Integer[] parameter 'copyIDs' is not present
15:31:05.374 [http-nio-8181-exec-4] WARN  org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver - Resolved exception caused by Handler execution: org.springframework.web.bind.MissingServletRequestParameterException: Required Integer[] parameter 'copyIDs' is not present

改进方法一：

请求报文不变，改接口，重新定义一个实体类，把数组参数作为它的一个属性

新定义一个​​MissionParam​​​类，包含​​Mission​​​的全部属性，外加​​copyIDs​​​属性

接口定义成这样

public ApiResult creMission(@RequestBody MissionParam missionParam)

改进方法二：

接口需要改，重新定义一个实体类​​​MissionParam​​​，里面只包含两个属性，​​Mission​​​和​​copyIDs​​​


接口定义成：

public ApiResult creMission(@RequestBody MissionParam missionParam)

请求参数格式改一下

{
    "mission": {
        "missionTitle": "新增任务测试",
        "missionContent": "任务内容",
        "missionType": "1",
        "etc": "2018-10-01 18:30:00",
        "missionScore": "5",
        "executerID": "3",
        "deptID": "2",
        "mangerID": "2",
        "remake": "",
        "explain": "分值是5分，抄送刘光宗、李四"
    },
    "copyIDs": [
        4,
        11
    ]
}

也可
