Mysql外链约束规则
java的mvc三层架构分别是: View(界面层),Service(业务逻辑层),DAO(数据访问层) V:View 网页视图,为用户提供能够看到并且使用的界面,与用户直接进行交互。 M:Model,业务模型,处理业务 C:Controller,控制器,处理请求,调用模型和视图 dao层负责对数据进行直接操控,最底层 service层负责对传递过来的参数验证,以及其他逻辑验证操作。验证完毕访问dao层进行数据操控 servlet层负责接收参数,然后调用service层进行处理 三个层分工合作,有利于后期的功能维护,那层出了问题就去处理哪层

讲解if语句之前先讲一下相关的运算符号 编程语言基本运算符号有: "<" ">" "==" "<=" ">=" "!=" 等 我挨个讲解他们的运算逻辑是怎么个实现的 首先是 ">" 运算符他的作用和数学上的 大于 相同,也是作为两个数的大小进行比较,如3>2,3肯定是大于2的,那么将会返回一个真条件,那如果是2>3,那么将会返回一个假条件,在c语言中,1代表真,0代表假,那么就是3>2返回1,2>3返回0 ">" 运算符和小于是相反的,和数学上面的比较方式类似 "==" 运算符在c语言中代表的是 "=" 打个比方就是1==1,将会返回一个真条件,就是1。如果是1==2那么将会返回0 另外的"<="以及">="同等与数学的 大于等于 和 小于等于。 "!=" 运算符表达的是不等于,也就是1!=1返回0,1!=2将会返回1。 上面是运算符------下面是if语句 if语句代表的就是c语言中的条件语句,写法: if(条件) { //条件为真后执行的代码区 } if语句中的条件值得就是上方的运算结果,打个比方: if(10>=9) { //条件为真后执行的代码区 printf("10>=9为真"); } 10>=9因为是正确的,最后会返回1,也就是真条件 接下来就是if中的else语句,写法: if(10>=9) { //条件为真后执行的代码区 printf("10>=9为真"); }else{ //条件为假后执行的代码区 printf("10>=9为假"); } else{}花括号中的代码在假条件时会被执行,但是10>=9是真条件,所以else花括号中的代码永远不会被执行 那么改成这样: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else{ //条件为假后执行的代码区 printf("10<=9为假"); } 因为10并不会小于等于9,所以条件为假,最后会执行的是else花括号中的代码,也就是printf("10<=9为假"); 最后就是else if()语句,这个语句代表的是:如果第一个if()中的条件未满足,那么将继续往下判断else if()中的条件是否为真: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else if(10>=9){ //条件为假后执行的代码区 printf("10>=9为真"); } 那么就是先判断10<=9是否未真,如果为真将会直接执行if(){}中的代码,如果为假,就会继续向下面的else if()中的条件进行判断是否为真,如果为真就执行else if()中的内容,如果为假则不执行。 当然if,else if以及else都是可以同时使用的: if(10<=9) { //条件为真后执行的代码区 printf("10<=9为真"); }else if(10>=9){ //条件为假后执行的代码区 printf("10>=9为真"); }else{ //上面条件全部为假 printf("上面条件全部为假"); } 这样写法就是当上面的if()以及else if()中的条件全部判断为假后将会执行else{}区块内的代码! ---最后是一点扩展内容--- c语言中的条件语句最后的结果都是0或者1,1==1最后会返回1,1==2最后会返回0,然而if()中写的条件最后也会变成0或者1。 if(1) { printf("条件为真"); } 那么这样写是不是也能执行呢?答案是可以的 我们可以写上两行代码来观测1==1最后返回的结果: int a = (1==1); printf("%d",a); 我这边调试最后打印的结果是1,也就是真条件。所以if()进行逻辑的判断

基本的逻辑比较运算符在前面笔记说过了 链接:http://notei.cn/note_see/64 这里主要是讲 与运算 或运算 非运算 学过一点电子逻辑门都应该有点概念的 与运算在C语言中用的符号是 "&&" 实际用法就是: if(10>=5 && 6<=5),顾名思义与逻辑就是要让两个逻辑同时为真最后才能返回真条件,反之就是假条件。 最后会返回的结果为0,为什么10>=5明明是真条件为什么会等于0呢?是因为6<=5是假条件导致整个运算结果也为假条件。 也可以多个条件一起进行运算if(1==1&&2==2&&3==3)多个条件一起运算也是可以的,如果三个条件都为真,那么最后会返回一个真条件,反之假条件。 或逻辑运算方式为只要有一个条件为真,那么最后就会返回真条件。反之全部为假条件,最后也只能返回假条件。符号为 "||" 用法为:if(1==1||2==3)。 非逻辑就是在条件的前面加一个 "!" 也就是小写的感叹号,让最后的逻辑取反。如果逻辑为真后加一个"!"条件将会变成假条件,反之为真。

Mysql外链约束规则
如果我们想通过一个成绩来得到等级: <span>{{ author.chengji >= 85 ? '优' : '良' }}</span> 可以在标签内渲染一个计算结果达到目的,不过这样会导致运算代码和其他标签内容混淆看起来很臃肿,我们可以通过Vue的计算属性computed来达到分开计算的方法: computed: { chengji:function() { return this.chengji >= 85 ? '优' : '良'; } } ><span>{{ chengji }}</span> 计算属性值会基于其响应式依赖被缓存,如果计算的参数没有发生改变,那么就会直接调用缓存中的结果,而不用再次调用函数获取结果 如果使用methods方法来计算的话,每当数据改变时页面会重新渲染,全部函数将全被执行

Java方法定义格式为: public static void 方法名称(参数){...} 例如: public static void test_fun(){ System.out.println("我的第一个方法"); } 调用方法就是直接 test_fun(); 使用void创建方法是不能使用return来返回结果的 想要返回结果需要使用其他类型例如: public static int 方法名称(参数){... return int} 这样的写法就可以返回一个int参数,其他类型也是一样的例子 -------下面讲讲其他语言的方法定义方式------- 首先就说说PHP的方法定义: function 方法名(参数){...} PHP定义方法时不需要定义方法的数据类型,可直接使用return返回各个类型的数据 另外就是C语言,定义方式: void 方法名(参数){...} C语言也是和Java类似,也是需要再定义时决定数据类型才可以进行返回相应的数据类型,例如int 方法名(参数){...}这样就可以返回一个int类型的
<?php /** * 功能:Curl外部资源请求函数封装 */ function postUrl($url,$data=[]){ /* $url - 指向URL连接 $data - 提交POST数据 */ $ch=curl_init(); curl_setopt($ch,CURLOPT_POST, true); curl_setopt($ch,CURLOPT_RETURNTRANSFER, true); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_POST,count($data)); curl_setopt($ch,CURLOPT_POSTFIELDS,$data); $response=curl_exec($ch); curl_close($ch); $result = json_decode($response,true); return $result; } #发送POST请求
Java数组创建方式 完整格式:数据类型[] 数组名 = new 数据类型[] {数组内容} 比如:int[] arr1 = new int[] {12,34,532}; 这样就定义了一个完整的数组格式 另外也可以用简写:int[] arr1 = {12,34,532}; 另外还有动态初始化的方式创建数组 完整格式:数据类型[] 数组名 = new 数据类型[数组类型] 比如:int[] arr1 = new int[3]; arr1[0] = 13; arr1[1] = 14; arr1[2] = 15; 先将数组动态创建完成,后期再进行输入录入 详细点的讲解可以看:http://notei.cn/user/note_see/60
