java的Object轉實體類對象

ObjectMapper objectMapper = new ObjectMapper();
Zjzfxmsp zfsp = objectMapper.convertValue(object, Zjzfxmsp.class);

上面的方式是可行的。

在這之前我嘗試了

Zjzfxmsp zfsp = (Zjzfxmsp) object;

這種方式強轉，雖然IDEA沒有報編譯錯誤

但是運行起來就報錯了

java.lang.ClassCastException: class java.util.LinkedHashMap cannot be cast to class cn.xxxxx.xxxxx.xxxx.models.Zjzfxmsp (java.util.LinkedHashMap is in module java.base of loader 'bootstrap'; cn.xxxxx.xxxxx.xxxx.models.Zjzfxmsp is in unnamed module of loader org.springframework.boot.loader.LaunchedURLClassLoader @728938a9)
