java的Object转实体类对象

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

上面的方式是可行的。

在这之前我尝试了

Zjzfxmsp zfsp = (Zjzfxmsp) object;

这种方式强转，虽然IDEA没有报编译错误

但是运行起来就报错了

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)
