JsonString to JavaObject at runtime

Question

我正在尝试在运行时将JSON String转换为Java对象。可能吗？

String className = errorInfo.getClassName();
		String methodName = errorInfo.getMethodName();
		String requestMessage = errorInfo.getMessage();
		String reference3 = errorInfo.getReference3();
		try {
			Class claz = Class.forName(className);
			Object obj = claz.newInstance();
			Class[] parameterTypes = new Class[1];
			parameterTypes[0] = Class.forName(reference3).getClass();
			Method method = claz.getMethod(methodName, parameterTypes);
			method.invoke(obj, new      
ObjectMapper().readValue(requestMessage,<I have to pass here .class reference>>));
}
catch(Exception ex)
{
}

我犯了基本错误。以下代码对我有用：

String className = errorInfo.getClassName();
String methodName = errorInfo.getMethodName();
String requestMessage = errorInfo.getMessage();
String reference3 = errorInfo.getReference3();
try {
Class<?> claz = Class.forName(className);
Object obj = claz.newInstance();
Class[] parameterTypes = new Class[1];
Class<?> parameter = Class.forName(reference3);
parameterTypes[0] = parameter;
Method method = claz.getMethod(methodName, parameterTypes);
method.invoke(obj, new 
ObjectMapper().readValue(requestMessage,parameter));
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
