今天在写maven+ssm框架时报如图所示错误点开target一看，我的xxxmapper.xml文件根本就没有被打包（所以报错信息写了找不到我在xxxmapper.xml写的方法）上网去查了查，找到如下解答构建Maven项目的时候，如果没有进行特殊的配置，Maven会按照标准的目录结构查找和处理各种类型文件。 Maven打包时，默认java目录下只将.java编译并将编译后的class文件打包，而mapper接口与mapper映射文件放在同一目录下时，mapper映射文件未被打包。解决方案如下在pom.xml文件的build节点下添加 resources节点 <resources> <resource> <directory>${basedir}/src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> 问题得到解决来源： CSDN 作者： zjs_scallop 链接： https://blog.csdn.net/zjs_scallop/article/details/104119291

《MapReduce:Simplified Data Processing on Large Cluster》阅读笔记

阅读更多关于《MapReduce:Simplified Data Processing on Large Cluster》阅读笔记

介绍 MapReduce是一种编程模式，以及与之相关的用于处理和生成大数据集的实现。其运作方式可以简单概括为以下步骤：一个大的输入被分成很多个小的输入块，同时，一个分布式系统中存在的多个计算机，组成一个大的计算机集群，这些分出来的小的输入块将会被集群中的计算机来执行，由一个 master 机器来分发人物。这些用于计算的机器成为 worker。master 将这个小的输入块分配给 worker，接下来就由worker来进行计算。我们称这个计算的过程为 Map，Map 会处理输入数据并生成一组结果。整个 Map 过程会产生很多个计算结果，我们称这些计算结果为中间值 (imtermediate value)。接下来，这些中间值就会被分配到 worker 中来执行 Reduce 任务，这个过程同样也是用 master 来分配的。关于 Reduce 任务，其主要目标即是合并具有相关联的中间值（key/value对）key值的中间值对，计算出结果。上述过程即是一个 MapReduce 任务的基本步骤。当然，过程的Map函数和Reduce函数是可由用户指定的。在 MapReduce 架构下设计的程序代码将会自动的并行运行并运行在一个分布式集群里。我们接下来要关心的则是：输入数据的划分，程序运行中机器的调度，机器计算等处理过程出错，以及管理机器之间的数据交流。在本篇笔记中

Metaballs in Processing as vector

问题 i am trying to create a kind of metaball, nice curves between two circles. Something like the image, the lines are drawn straight but can also be more curved. I need them as a vector in Processing. Does anyone can help me? thanks in advance! Example in paperjs: http://paperjs.org/examples/meta-balls/ image: http://www.smeulders.biz/tmp/metaballs.png void setup() { size(500,500); ellipse(100, 250, 100, 100); ellipse(350, 250, 200, 200); } void draw() {} 回答1: With a bit of math (to workout

Choose direction to start flood fill algorithm for loop detection

阅读更多关于 Choose direction to start flood fill algorithm for loop detection

问题 I've implemented a flood fill algorithm for matrices in my program, and I'd like to choose in which direction it starts. I want to detect loops created by elements on the grid: When there is an element at a given place on the grid, a 1 is displayed in the matrix. When there isn't anything, it's a 0. And when it is elements that won't be moved, it's a 2. The flood fill algorithm starts on a 1 and turns every 1 it encounters into a 2. example: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Processing P3D Animation leaving artifacts behind

阅读更多关于 Processing P3D Animation leaving artifacts behind

问题 I am trying to make a spinning cube in Processing's P3D with this code: int sizes = 500; int rotation = 0; void setup() { size(500, 500, P3D); } void draw() { lights(); translate(sizes/2, sizes/2, 0); rotateY(rotation * (PI/180)); rotateX(rotation * (PI/180)); background(0); box(sizes/2); rotation = (rotation + 1); } When I run it the cube does spin as I wanted, but there are strange 'artifacts' (for lack of a better name) left behind its edges. What causes this issue, and can it be solved?

问题 This code works fine in processing 2 but using variables in processing 3 in the size() function does not work, how would i go about implementing displaywdith-100 in processing 3 int val, screen_increment, old_x=0, old_y=0; String inString; int lf = 10; void setup() { size(displayWidth-100, 600);// The screen height is set to be 600, which matches the scaled data, String portName = Serial.list()[0]; println(Serial.list()); myPort = new Serial(this, portName, 115200); myPort.bufferUntil(lf);
