通过com.fastxml.jackson的ObjectMapper对象进行转换：

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.convertValue(Object fromValue, Class<T> toValueType);

例子：

Result result1 = eduClient.getCourseInfoOrder(courseId);
ObjectMapper mapper = new ObjectMapper();
CourseWebVoOrder course = mapper.convertValue(result1.getData().get("course"), CourseWebVoOrder.class);
