通过chrome中的POSTMAN rest客户端获取Json数据

Question

我试图通过postman rest客户端，使用json数据和POST方法测试后端服务。

前2个参数是数组列表，其余都是字符串或整数我传递的数据如下：

{
 "watchUsers":["user1"],
 "msgUsers":["user2"],
 "status":1,
 "sendTime":319876,
 "compId":"turbo",
 "workId":"ts",
 "startId":"engine",
 "endId":"restore",
 "msg":"Completed Successfully"
}

我的控制器接受以下内容：

public WatchDTO add(@RequestBody ArrayList<String> watchUsers,@RequestBody ArrayList<String> msgUsers, Integer status, Integer sendTime, String compId, String workId, String startId, String endId, String msg){
.....
}

提交后，我得到以下错误：组织。springframework。http。转换器。HttpMessageNoteableException：无法读取JSON：无法反序列化java实例。util。ArrayList out of START_OBJECT token位于[源：org.apache.catalina.connector]。CoyoteInputStream@4c352e08; 行：1，列：1]；嵌套异常为org。科德豪斯。杰克逊。地图JsonMappingException：无法反序列化java实例。util。ArrayList out of START_OBJECT token位于[源：org.apache.catalina.connector]。CoyoteInputStream@4c352e08; 行：1，列：1]

知道如何传递数组吗

定义java bean如下-

<代码>

import java.util.ArrayList;

public class UserStat {
    ArrayList<String> watchUsers;
    ArrayList<String> msgUsers;
    int status;
    int sendTime;
    String compId;
    String workId;
    String startId;
    String endId;
    String msg;

    public ArrayList<String> getWatchUsers() {
        return watchUsers;
    }

    public void setWatchUsers(ArrayList<String> watchUsers) {
        this.watchUsers = watchUsers;
    }

    public ArrayList<String> getMsgUsers() {
        return msgUsers;
    }

    public void setMsgUsers(ArrayList<String> msgUsers) {
        this.msgUsers = msgUsers;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }

    public int getSendTime() {
        return sendTime;
    }

    public void setSendTime(int sendTime) {
        this.sendTime = sendTime;
    }

    public String getCompId() {
        return compId;
    }

    public void setCompId(String compId) {
        this.compId = compId;
    }

    public String getWorkId() {
        return workId;
    }

    public void setWorkId(String workId) {
        this.workId = workId;
    }

    public String getStartId() {
        return startId;
    }

    public void setStartId(String startId) {
        this.startId = startId;
    }

    public String getEndId() {
        return endId;
    }

    public void setEndId(String endId) {
        this.endId = endId;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

}

修改控制器内的方法如下-

公共WatchDTO添加（@Request estBody UserStat userStat）{

}

这应该可以
