the dependencies of some of the beans in the application context form a cycle
前些天在项目发布启动中遇到这个“the dependencies of some of the <em>beans</em> in the <em>application</em> <em>context</em> <em>form</em> a <em>cycle</em>”问题 由字面意思就知道是由于代码中存在着循环依赖导致的,于是我便在代码中查找到底哪些注入互相引用了,有时代码之间依赖太复杂,人工查找的话太耗费时力,使用idea的话就很容易能查找到,我简单说一下在idea中怎样...

Spring循环依赖
一、什么是循环依赖 循环依赖就是循环引用,即两个或者多个bean相互之前的持有对方,如下图: A引用B,B引用C,C又引用A,最终反应为一个环。 注意:此处不是循环调用,循环调用是方法之间的环调用,而且循环调用是无法<em>解决</em>的,除非有终结条件,否则就是死循环,最终导致内存溢出错误。 二、Spring<em>解决</em>循环依赖的方式 Spring容器循环依赖的场景: 构造器循环依赖 sette...

Spring中的循环依赖问题介绍及解决方法
Spring容器能顺利的实例化以构造函数注入方式配置的bean有一个前提:即bean构造函数入参引用的对象必须已经准备就绪。 那么如果两个bean都采用构造函数注入,并且都通过构造函数入参引用了对方。就会发生类似与线程死锁的循环依赖问题。 那么接下来我们看一个发生循环依赖问题的例子: public class Car{ private String brand; privat

Problem DescriptionnEry is interested in graph theory, today he ask BrotherK a problem about it: Given you a undirected graph with N vertexes and M edges, you can select a vertex as your starting point, then you need to walk in the graph along edges. However, you can't pass a edge more than once, even opposite direction is forbidden. At the end, you should come back to the starting point. Assume you has passed X edges, there are two questions:nnQuestion 1: Can X be a odd number ?nnQuestion 2: Can X be a even number ?nn(note: you must walk, so X can't be 0)n nnInputnThe first line contains a single integer T, indicating the number of test cases.nnEach test case begins with two integer N, M, indicating the number of vertexes and the number of edges. Following M lines, each line contains two integers Ui, Vi, indicating there are a edge between vertex Ui and vertex Vi.nnT is about 30nn1 ≤ N ≤ 100000nn0 ≤ M ≤ 300000nn1 ≤ Ui,Vi ≤ NnnUi will not equal to VinnThere is at most one edge between any pair of vertex.n nnOutputnFor each test, print two lines.nnThe first line contains "YES" or "NO" for question 1. nnThe second line contains "YES" or "NO" for question 2.n nnSample Inputn3n1 0n3 3n1 2n2 3n3 1n4 4n1 2n2 3n3 4n4 1n nnSample OutputnNOnNOnYESnNOnNOnYES

Beans
Problem Descriptionn Mr. Pote's shop sells <em>beans</em> now. He has N bags of <em>beans</em> in his warehouse, and he has numbered them with 1, 2, …, N according to their expired dates. The i-th bag contains Wi units of <em>beans</em>. For selling at retail makes only a little profit, Mr. Pote want to pack <em>beans</em> in small packets with certain size and sell them in packets. Here comes his packing way:n Suppose the size of the packet is P units. Firstly, Mr. Pote selects some bags (at least one) of <em>beans</em> with consecutive number in his warehouse. Then he takes out the <em>beans</em> from all selected bags, and puts them together on the desktop. To pack the <em>beans</em>, he take P units of <em>beans</em> from desktop and fill in a new packet each time, until the <em>beans</em> left are less than P units. Finally the <em>beans</em> left on the desktop are eaten by a lucky dog.n Mr. Pote doesn't want the dog eat too many <em>beans</em>, so he prefers to solutions that resulting no more than K units of <em>beans</em> eaten by the dog. Moreover, he also wants to pack as many packets as possible. Could you tell him how many packets he can pack at most without breaking his preference?n nnInputn On the first line of input, there is a single positive integer T < N, P < 1000001, 0 < P)n Next follow a line with N integers W1, W2, ..., WN. The i-th integers describes the amount of <em>beans</em> in the bags numbered i. (0 < 32768)n Numbers are separated by spaces.n nnOutputn For each test case you should output a single line containing "Case X: Y" (quotes for clarity) where X is the number of the test case (starting at 1) and Y is the maximum number of packets that Mr. Pote can pack following his way. n In case there's no solution avoiding the dog eats more than K units of <em>beans</em>, Y should be equal to -1.n nnSample Inputn3n10 20 10n0 3 1 8 19 39 2 9 1 8n3 100 10n32 34 23n1 5 3n1n nnSample OutputnCase 1: 4nCase 2: -1nCase 3: 0
