List<User> approverList = JsonUtils.jsonToList(taskApplyInfo.getApprover(),User.class); List<User> approverTwo = JsonUtils.jsonToList(taskApplyInfo.getApproveTwo(),User.class); List<User> approverThree = JsonUtils.jsonToList(taskApplyInfo.getApproveThree(),User.class); List<User> collaboratorTwo = JsonUtils.jsonToList(taskApplyInfo.getCollaboratorTwo(),User.class); List<User> collaboratorList = JsonUtils.jsonToList(taskApplyInfo.getCollaborator(),User.class); if ((null == approverList || approverList.size() == 0) && (null == collaboratorList || collaboratorList.size() == 0) && (null == approverTwo || approverTwo.size() == 0) && (null == collaboratorTwo || collaboratorTwo.size() == 0) && (null == approverThree || approverThree.size() == 0)) { return false; } return true;优化代码

这段代码中，使用了JsonUtils.jsonToList()方法将taskApplyInfo对象中的五个字段转换为List<User>类型，分别是approver、approveTwo、approveThree、collaboratorTwo、collaborator，然后判断approverList是否为空或长度为0。

相关问题

优化下列代码List<User> approverList = JsonUtils.jsonToList(taskApplyInfo.getApprover(),User.class); List<User> approverTwo = JsonUtils.jsonToList(taskApplyInfo.getApproveTwo(),User.class); List<User> approverThree = JsonUtils.jsonToList(taskApplyInfo.getApproveThree(),User.class); List<User> collaboratorTwo = JsonUtils.jsonToList(taskApplyInfo.getCollaboratorTwo(),User.class); List<User> collaboratorList = JsonUtils.jsonToList(taskApplyInfo.getCollaborator(),User.class); if ((null == approverList || approverList.size() == 0) && (null == collaboratorList || collaboratorList.size() == 0) && (null == approverTwo || approverTwo.size() == 0) && (null == collaboratorTwo || collaboratorTwo.size() == 0) && (null == approverThree || approverThree.size() == 0)) { return false; } return true;

这段代码将通过使用 JsonUtils 类的 jsonToList 方法将多个字符串转换为 User 类型的 List。然后，它检查 approverList 是否为空或大小为 0。如果是这样，它将执行某些操作。

Map<String, Object> stringObjectMap = JSONUtils.jsonStrToMap(params); 怎么转成<String.String>

要将Map<String, Object>转换为Map<String, String>，你可以遍历原始的Map，然后将每个键值对中的值转换为String类型，并将其放入新的Map中。以下是示例代码：

Map<String, Object> stringObjectMap = JSONUtils.jsonStrToMap(params);
Map<String, String> stringStringMap = new HashMap<>();

for (Map.Entry<String, Object> entry : stringObjectMap.entrySet()) {
    String key = entry.getKey();
    Object value = entry.getValue();
    String stringValue = String.valueOf(value);
    stringStringMap.put(key, stringValue);
}

这样，你就可以将Map<String, Object>转换为Map<String, String>了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
