异常信息:
org.springframework.beans.FatalBeanException: Failed to obtain BeanInfo for class [xxxx(某一实体类)]; nested exception is java.beans.IntrospectionException: type mismatch between read and write methods
原因:实体类中的get方法返回值和改get方法对应的字段类型不一致导致的,
比如字段createTime类型是Timestamp,然后get的返回值是Date,这样子在jdk1.7中不会报错,但是在1.8就会报如上异常
