这个错误信息显示了一个类型转换异常(ClassCastException)。错误提示信息中指出,java.util.LinkedHashMap 不能被转换为 com.sitech.prom.channelsettle.rehearsal.busi.compute.vo.DatasyncJobIdDatasyncStatusVo 类型。根据错误信息,错误发生在 TimeScanRemoteScheduler.java 文件的第149行,你可以检查一下这个代码位置,看看是否有类型转换的问题。

java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.vo.EquipmentDeviceStatus
根据提供的引用内容,出现`java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.vo.EquipmentDeviceStatus`的错误是因为将`java.util.LinkedHashMap`类型的对象强制转换为`com.vo.EquipmentDeviceStatus`类型时发生了类型转换异常。
解决这个问题的一种方法是使用`ObjectMapper`类的`convertValue`方法将`LinkedHashMap`对象转换为`EquipmentDeviceStatus`对象。以下是一个示例代码:
```java
ObjectMapper mapper = new ObjectMapper();
LinkedHashMap<String, Object> linkedHashMap = (LinkedHashMap<String, Object>) confirmParms.get("devices");
EquipmentDeviceStatus equipmentDeviceStatus = mapper.convertValue(linkedHashMap, EquipmentDeviceStatus.class);
```
在这个示例中,我们首先使用`ObjectMapper`类创建一个对象`mapper`。然后,我们从`confirmParms`中获取到`devices`对象,并将其强制转换为`LinkedHashMap`类型。最后,我们使用`mapper.convertValue`方法将`LinkedHashMap`对象转换为`EquipmentDeviceStatus`对象。
请注意,为了使上述代码正常工作,确保`com.vo.EquipmentDeviceStatus`类正确定义,并且`confirmParms`中的`devices`对象是一个`LinkedHashMap`类型的对象。
java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to java.util.List
java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to java.util.List是一个类型转换错误。它表示试图将一个LinkedHashMap对象强制转换为List对象,但是类型不兼容,因此导致了ClassCastException异常。
解决这个问题的方法是使用ObjectMapper类将LinkedHashMap对象转换为List对象。下面是一个示例代码:
```java
// 获取table,转成list集合
ObjectMapper mapper = new ObjectMapper();
List<OrderMatchingProcess> list = mapper.convertValue(message.getFormData().get("table"), new TypeReference<List<OrderMatchingProcess>>() {});
```
这段代码使用了ObjectMapper的convertValue方法,将LinkedHashMap对象转换为List<OrderMatchingProcess>对象。通过指定TypeReference<List<OrderMatchingProcess>>来确保转换的准确性。
请注意,你需要根据实际情况修改代码中的类型和变量名。
