List<Map<String, Object>> maps

List<Map<String, Object>> maps是一个List集合,其中的元素是Map对象。这个Map对象的键是String类型,值是Object类型。这种数据结构通常用于存储多个键值对,每个键值对都可以用一个Map对象来表示。在Java中,可以使用for循环或者迭代器来遍历List集合中的Map对象,然后使用get方法获取Map对象中的键值对。如果需要对Map对象中的键值对进行修改,可以使用put方法。如果需要删除Map对象中的某个键值对,可以使用remove方法。

List<Map<String, Object>> maps = new ArrayList<>();
This code declares an empty ArrayList of maps. Each map in the list will have keys that are strings and values that are objects. The type of objects that can be stored in the map is not specified here. The list can be used to store a collection of maps, each representing a set of key-value pairs.
public ResultPend screen(List<Map<String, Object>> pending){ Map<String,Object> maps = new HashMap<>(); for (Map<String, Object> map : pending) { //获取到pending里面的data Object datas = map.get("data"); List<Map<String,Object>> list = (List<Map<String, Object>>) datas; for (Map<String, Object> objectMap : list) { Object processInstName = objectMap.get("processInstName"); maps.put("processInstName",processInstName); Object metadataName = objectMap.get("metadataName"); maps.put("metadataName", metadataName); Object originBusinessName = objectMap.get("originBusinessName"); maps.put("originBusinessName",originBusinessName); Object originatorName = objectMap.get("originatorName"); maps.put("originatorName", originatorName); Object originTime = objectMap.get("originTime"); maps.put("originTime", originTime); Object processDefineName = objectMap.get("processDefineName"); maps.put("processDefineName", processDefineName); Object processNodeInstName = objectMap.get("processNodeInstName"); maps.put("processNodeInstName", processNodeInstName); Object tenantName = objectMap.get("tenantName"); maps.put("tenantName", tenantName); Object enterpriseName = objectMap.get("enterpriseName"); maps.put("enterpriseName", enterpriseName); Object createUserId = objectMap.get("createUserId"); maps.put("createUserId", createUserId); Object createdTime = objectMap.get("createdTime"); maps.put("createdTime",createdTime); } } }怎么把上述代码中的maps集合转成ResultPend对象并返回
要将maps集合转换为ResultPend对象并返回,你需要创建一个ResultPend对象,并将maps中的数据设置到相应的属性中。可以按照以下步骤进行操作:
1. 创建ResultPend对象:
```java
ResultPend resultPend = new ResultPend();
```
2. 从maps中取出数据,并设置到ResultPend对象的属性中:
```java
resultPend.setProcessInstName((String) maps.get("processInstName"));
resultPend.setMetadataName((String) maps.get("metadataName"));
resultPend.setOriginBusinessName((String) maps.get("originBusinessName"));
resultPend.setOriginatorName((String) maps.get("originatorName"));
resultPend.setOriginTime((String) maps.get("originTime"));
resultPend.setProcessDefineName((String) maps.get("processDefineName"));
resultPend.setProcessNodeInstName((String) maps.get("processNodeInstName"));
resultPend.setTenantName((String) maps.get("tenantName"));
resultPend.setEnterpriseName((String) maps.get("enterpriseName"));
resultPend.setCreateUserId((String) maps.get("createUserId"));
resultPend.setCreatedTime((String) maps.get("createdTime"));
```
3. 返回ResultPend对象:
```java
return resultPend;
```
请注意,这里假设ResultPend类已经定义并具有相应的属性和setter方法来设置数据。
