異常信息:
org.springframework.beans.FatalBeanException: Failed to obtain BeanInfo for class [xxxx(某一實體類)]; nested exception is java.beans.IntrospectionException: type mismatch between read and write methods
原因:實體類中的get方法返回值和改get方法對應的字段類型不一致導致的,
比如字段createTime類型是Timestamp,然後get的返回值是Date,這樣子在jdk1.7中不會報錯,但是在1.8就會報如上異常
