for (String constructDepartmentId : constructDepartmentIds) {报错foreach not applicable to type 'java.lang.Object'怎么改

这个错误通常是因为 `constructDepartmentIds` 的类型未指定导致的。你可以尝试显式地指定 `constructDepartmentIds` 的类型，例如：

for (String constructDepartmentId : (List<String>) constructDepartmentIds) {
    // 循环体
}

或者在定义 `constructDepartmentIds` 变量时指定其类型，例如：

List<String> constructDepartmentIds = new ArrayList<>();
// 添加元素
for (String constructDepartmentId : constructDepartmentIds) {
    // 循环体
}

这样就可以避免 `foreach not applicable to type 'java.lang.Object'` 的错误。

foreach not applicable to type 'java.util.Map<java.lang.String,java.lang.Object>'

`foreach` is not applicable to `Map` in Java. You can use `Map.entrySet()` to iterate through the key-value pairs of a map. Here’s an example:

Map<String, Object> map = new HashMap<>();
map.put("key1", "value1");
map.put("key2", "value2");

for(Map.Entry<String, Object> entry : map.entrySet()) {
    String key = entry.getKey();
    Object value = entry.getValue();
    System.out.println(key + " : " + value);
}

This will output:

key1 : value1
key2 : value2

You can replace the `System.out.println()` statement with your own logic to process each key-value pair.
