Map 类型的表达式需要未经检查的转换

Question

我的代码中有这个：

ObjectMapper oMapper = new ObjectMapper();
Map<String, Object> objectMap = oMapper.convertValue(test, Map.class);

我收到以下警告：

Type safety: The expression of type Map needs unchecked conversion to conform to Map<String,Object>

我该如何解决这个问题？

解决方案：

import com.fasterxml.jackson.core.type.TypeReference;

ObjectMapper oMapper = new ObjectMapper();
Map<String, Object> objectMap = oMapper.convertValue(prueba, new TypeReference<Map<String, Object>>(){});
