将Map转换为Java，某些属性无法正确设置

Question

//我使用这个简单的程序:公共静态对象convertToBean(类类型，映射){ BeanInfo beanInfo；对象obj =空；尝试{ beanInfo = Introspector.getBeanInfo( type )；obj = type.newInstance()；

            // When I debugging to here, I found that some properties is different from the variable the Object own. PropertyDescriptor changes charactor case when the variable is not in "String" type.
            PropertyDescriptor[] propertyDescriptors = beanInfo.getPropertyDescriptors();
            for (PropertyDescriptor descriptor : propertyDescriptors) {
                String propertyName = descriptor.getName();

                if (map.containsKey(propertyName)) {
                    Object value = map.get(propertyName);
                    Object[] args = new Object[1];
                    args[0] = value;
                    descriptor.getWriteMethod().invoke(obj, args);
                }
            }
        } catch (Exception ignored) {
        }
        return obj;
    }

//Using BeanMap is the same question.

最后我找到了根本原因。问题通过将"a01“改为”a01“来解决。变量名必须是严格的骆驼规则。第一个字符必须是小写，除了前两个字符都是大写字母，比如"AD“。因为setter和getter方法将以相同的模式生成。所以很难识别出一个变量的真名。
