com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: com.yu.app.web.form.ResultRentSearch[“data”]->com.yu.app.web.form.HouseAllInfoAndImage[“houseInfo”]->com.yu.app.entity.HouseInfo_$$_jvste6d_1[“handler”])

在hibernate查询数据,并将数据转化为json的时候报错,原因是hibernate在配置表A与表B之间的映射时，会在类A中引用类B，在类B中引用类A。当其中一个对象用jackson转成json时，会造成他们之间的无限引用，直到报错.
解决办法:

在引用类及被引用类上加上注解

@JsonIgnoreProperties(value = {"handler","hibernateLazyInitializer","fieldHandler"})

导包
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
这样正常不报错!
