 public static final Map<Integer, List<CrmDetailViewEnum>> DEFAULT_VIEW = new HashMap<Integer, List<CrmDetailViewEnum>>() { private static final long serialVersiOnUID= -4318860703552426339L; { put(SHORTCUT_BAR_TYPE, Arrays.asList(CrmDetailViewEnum.CALL_PHONE,CrmDetailViewEnum.SEND_MSG, CrmDetailViewEnum.SEND_QQ, CrmDetailViewEnum.SEND_EMAIL)); put(INFO_BAR_TYPE, Arrays.asList(CrmDetailViewEnum.INFO, CrmDetailViewEnum.PHONE_NUM, CrmDetailViewEnum.WECHAT, CrmDetailViewEnum.QQ, CrmDetailViewEnum.EMAIL, CrmDetailViewEnum.CONTACT_BOOK, CrmDetailViewEnum.GUEST)); put(APPLICATION_BAR_TYPE, Arrays.asList(CrmDetailViewEnum.CONTACT,CrmDetailViewEnum.ORDER, CrmDetailViewEnum.TASK, CrmDetailViewEnum.FILE, CrmDetailViewEnum.EXTEND_APPLICATION)); } };

关于 list 里面的 values 全是 null ，我猜测是加载顺序的问题，但是我不知道解决办法；

目前我采用了两种

 //初始化类 private static CrmDetailViewEnum crmDetailViewEnum;

public static final Map<Integer, List<CrmDetailViewEnum>> DEFAULT_VIEW; static { DEFAULT_VIEW = new HashMap<Integer, List<CrmDetailViewEnum>>() { private static final long serialVersiOnUID= -4318860703552426339L; { put(SHORTCUT_BAR_TYPE, Arrays.asList(CrmDetailViewEnum.CALL_PHONE,CrmDetailViewEnum.SEND_MSG, CrmDetailViewEnum.SEND_QQ, CrmDetailViewEnum.SEND_EMAIL)); put(INFO_BAR_TYPE, Arrays.asList(CrmDetailViewEnum.INFO, CrmDetailViewEnum.PHONE_NUM, CrmDetailViewEnum.WECHAT, CrmDetailViewEnum.QQ, CrmDetailViewEnum.EMAIL, CrmDetailViewEnum.CONTACT_BOOK, CrmDetailViewEnum.GUEST)); put(APPLICATION_BAR_TYPE, Arrays.asList(CrmDetailViewEnum.CONTACT,CrmDetailViewEnum.ORDER, CrmDetailViewEnum.TASK, CrmDetailViewEnum.FILE, CrmDetailViewEnum.EXTEND_APPLICATION)); } }; }

这两种一起使用的，然后成功了，不为 null 了，但是不太懂原理，所以想请教一下各位大佬原因

本地是可以的，但是云环境可能是有路径问题解析类的时候顺序不一致为 null 。本地我自测是没问题的

```java
import com.alibaba.fastjson.JSON;

import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class For {
public static final Map<Integer, List<TempEnum2>> DEFAULT_VIEW = new HashMap<Integer, List<TempEnum2>>() {
private static final long serialVersiOnUID= -4318860703552426339L;
{
put(1, Collections.singletonList(TempEnum2.ADDRESS));
put(2, Collections.singletonList(TempEnum2.ADDRESS));
put(3, Collections.singletonList(TempEnum2.URL));
}
};
public static void main(String[] args) {
System.out.println(JSON.toJSONString(DEFAULT_VIEW));
}
}
enum TempEnum2 {
ADDRESS(""),
URL("");
private String pptFromDetail;
TempEnum2(String pptFromDetail) {
this.pptFromDetail = pptFromDetail;
}
}
```

第一种情况是没问题的，打印正常

{1:["ADDRESS"],2:["ADDRESS"],3:["URL"]}

@RedBeanIce 我本地试了确实正常，但是发到测试环境后的日志显示除了 key 是有数据的，枚举类全是 null
