　　当时,我就吓坏了.尼玛,这不是内存溢出了吗?吓得我赶紧去检查了每一个有遍历语句的代码,结果没有发现一个死循环,折腾了两个多小时,最后终于发现了问题,简直让人抓狂,原因竟然是我在实体类,order(订单),orderItem(订单项)中都重写了ToString()方法.请看:
OrderItem.java:
package com.wang.shop.order.
import com.wang.shop.goods.entity.G
public class OrderItem {
private Integer itemId;//订单项Id
private I//商品数量
private double//商品总价格
//订单项中的商品
//订单项所属的订单
//get/set方法省略
public String toString() {
return "OrderItem [itemId=" + itemId + ", count=" + count + ", total="
+ total + ", goods=" + goods + ", order=" + order + "]";
Order.java:
package com.wang.shop.order.
import java.util.D
import java.util.HashS
import java.util.S
import com.wang.shop.user.entity.U
* 订单实体
* @author Administrator
public class Order {
private Integer orderId;//订单Id
private S//收货人姓名
private S//收货地址
private S//收货人电话
private String postN//邮编
private double allT
private Date orderD//订单创建日期
//订单所属的用户
U//所有用户
//订单里面的多个订单项
private Set&OrderItem& orderItems=new HashSet&OrderItem&();
//get/set方法省略
public String toString() {
return "Order [orderId=" + orderId + ", name=" + name + ", address="
+ address + ", tel=" + tel + ", postNum=" + postNum
+ ", allTotal=" + allTotal + ", orderDate=" + orderDate
+ ", user=" + user + ", orderItems=" + orderItems + "]";
请注意!请注意!请注意! 在order类中我有一个set集合的属性,value正好是orderItem,而我又重写了OrderItem的ToString方法,于是乎,当代码执行:
　　System.out.println("order:"+order);或者System.out.println("orderItem:"+orderItem);
　　的时候,程序打印Order时,会打印OrderItem,打印OrderItem时,会打印Order,如果反复,无限循环~~~~~最后,啪叽,内存溢出.这个错误有点让人哭笑不得,第一次遇到,真是然我手足无措,立碑如此,切勿再犯.

请各位大侠帮菜小弟看看吧，实在是不知道错在哪里呀，正儿八经的急得很哦，在这先谢谢啦！同祝圣诞快乐哦各位亲~
把EsbCapabilityServiceImpl代码贴出来,你是不是方法自己调自己了,导致栈溢出
Property 'esbcapabilityService' nested exception is java.lang.StackOverflowError
看看是不是esbcapabilityService这个bean有问题
建议先clear下重新编译运行试试
Error creating bean with name '/esbmonitor' defined in ServletContext resource [/WEB-INF/spring/esbcapabilityContext.xml]
