+## SpringBoot
+注:下面的版本号1.0,2.0等等仅代表发展历程演变,不代表该技术真实发布版本号
+### web开发初级阶段:
+servlet+jsp web开发的初级阶段。mvc三层架构 m:model v:view c:controller
+### web开发推进发展1.0
+之后同一时期出现三种:
+SSH
+struct 1.0 起初解决mvc 扩展名为.do的网站
+spring 1.0 起初专注于创建对象。单例对象。
+hibernate 1.0 :orm关系映射。将数据库中的结果集转换为Java对象,无需自己写sql。
+### web开发推进发展2.0
+之后发展:
+SSH2
+struct 2.0 .action扩展名
+spring 2.0 加入aop功能,面向切面功能
+mybaits:orm 轻量级,需要程序员自己写sql
+hibernate 2.0+
+### web开发推进发展3.0
+SSM
+需要使用xml进行配置
+springMVC:解决MVC,替代struct2.0
+Spring 3.0+ 增加更多功能,模块化
+mybaits 3.0+ 替代hibernate
+
+微服务:把一个大项目拆分成小的项目,然后根据需要进行整合。(例如:微信上面的小程序)规模小
+SpringBoot 不是一个框架。一个快速开发脚手架。快速开发,在一定程度上限制了自由性,有固定的目录结构,有约定俗成的配置。
+
+> 约定大于配置
+
+SpringBoot != SSM
+SpringBoot整合SSM
+
+
+### idea配置一个springboot项目:
+
+
+
+
+根包:com.ysy
+主启动类
+
+以spring- boot-start开头的依赖是启动器,自动配置
+
+### Spring框架的两项核心功能
+#### 一. 控制反转
+ Spring:将创建对象的权限交给spring框架,称之为控制反转 Inverse Of Control 简称ioc
+
+> IOC概念理解如下图,借鉴自:https://blog.csdn.net/bestone0213/article/details/47424255?fromshare=blogdetail&sharetype=blogdetail&sharerId=47424255&sharerefer=PC&sharesource=ysy1648067239&sharefrom=from_link
+> 
+
+#### 二. 依赖注入
+Spring框架自动将容器中的实例,自动赋值给需要的类,DI
+Autowired: 依赖注入注解
+##### 2.1依赖注入的三种方式:
+###### 2.1.1字段注入
+```java
+ @Autowired
+ private StudentService studentService ;
+```
+###### 2.1.2setter注入
+```java
+ @Autowired
+ public void setStudentService(StudentService studentService) {
+ this.studentService = studentService;
+ }
+```
+###### 2.1.3 构造器注入
+构造器注入可以省略Autowired注解
+```java
+ @Autowired //构造器注入可以省略此行注解
+ public StudentController(StudentService studentService){
+ this.studentService= studentService;
+ }
+
+```
+#### 2.2 依赖注入相关注解解释:
+##### 2.2.1 @Autowired
+1.默认按类型匹配 使用频率比较高
+
+```
+@Autowired
+ private StudentService studentService;
+```
+就会去容器里去找StudentService类型的实例去匹配,此时不加其他注解的前提下,容器里只能有一个该类型的实例,否则注解就不知道该去找哪个实例。
+
+**当有多个匹配时**
+1.可以使用@Primary注解表示优先
+
+> 比如StudentServiceImpl和MyStudentServiceImpl两个类均实现StudentService接口进行实例化,那么,@Primary加在哪个类上,哪个类优先级就高,@Autowired就会优先去找这个类
+
+2.按名称匹配
+
+> 首先,@Component变成@Component("i1"),也就是括号里加上名字,(@Component注解不加括号写名字时,默认的名字是@Component下类名的首字母小写)
+> 然后,cotroller层需要搭配 @Qualifier()注解,加上 @Qualifier(“i1”)。此时,
+> @Autowired注解就会找 @Qualifier(“i1”)指定的@Component("i1")所在的类实例化
+
+##### 2.2.2@Resource注解:
+功能类似于 Spring 的 @Autowired 注解,也是用于依赖注入,默认是按名称进行装配(byName),如果找不到匹配的名称,则按类型装配(byType)
+1.默认按名称匹配注入 按name值
+```
+ @Resource(name = "i1")
+```
+2.按类型匹配注入:通过type属性
+
+```
+ @Resource(type = StudentService.class)
+```
+3.上面两个结合使用:
+```
+ @Resource(type = StudentService.class,name = "i1")
+```
+##### 2.2.3 @Component注解的变种
+首先回顾@Component注解的作用:
+> 当一个类被标记为 @Component 时,Spring 容器会在启动时自动扫描并实例化这个类,并将其注册到 Spring 上下文中
+> @Component 注解可以用于任何类,包括控制器、服务、DAO 等。当一个类被标记为 @Component 时,它就成为了 Spring 上下文中的一个 bean,可以被其他 bean 通过依赖注入的方式使用。
+
+该注解的“变种”:
+> spring官方认为@Component注解过于中性,不易理解,所以引入了以下几种进行区分
+
+@Service 用于标注业务层组件
+@Repository (仓储)用于标注数据访问组件,即DAO组件
+@Controller 用于标注控制层组件
+ @RestController 本质上是 @Controller + @ResponseBody,因此无需每个方法都添加 @ResponseBody,简化了开发。除了具有@controller的功能之外,还会实现@ResponseBody ,也就是声明返回值
+
+
+> @Component 和@Service,@Repository (仓储),@Controller
+> ,@RestController一样,自动创建唯一实例 ,在目前的 Spring 版本中,这 3 个注释和 @Component 是等效的,但是从注释类的命名上,很容易看出这 3 个注释分别和持久层、业务层和控制层(Web 层)相对应。
+> 虽然目前这3 个注释和 @Component 相比没有什么新意,但 Spring 可能将在以后的版本中为它们添加特殊的功能。
+##### @Component与@Bean的区别和联系
+@Component 作用于类,@Bean作用于方法。
+@Bean 需要在配置类中使用,即类上需要加上@Configuration注解
+
+
+相同点:两者的目的是一样的,都是注册bean到Spring容器中。
+两者都可以通过@Autowired装配
+##### 有@Component为何还需要@Bean呢?
+如果你想要将第三方库中的组件装配到你的应用中,在这种情况下,是没有办法在它的类上添加@Component注解的,因此就不能使用自动化装配的方案了,但是我们可以使用@Bean,就像上图那种方法。
+
+#### 各种@xxxMapping注解
+
+在Controller中,一个方法只有指定@XXXMapping才能接收并处理请求
+
+1.@GetMapping:接收get类型的请求
+```java
+@GetMapping(value = "/student/list",produces =
+"application/json;charset=utf-8")
+//produces是指定数据类型
+```
+2.@PostMapping接收post类型的请求
+3.@PutMapping接收put类型的请求
+4.@PatchMapping接收patch类型的请求
+5.@DeleteMapping接收delete类型的请求
+
+6.@RequestMapping 是一个通用的注解,接收任意类型的请求,但可以指定类型,produces属性指定响应类型,这是最早的注解,后来为了方便使用,根据HTTP方法细分出了上述的专用注解。
+
+```java
+ @RequestMapping(value = "/student/list",method ={
+ RequestMethod.GET,RequestMethod.POST})
+
+```
+> 这些@xxxMapping也可以添加到类上。表示所有方法以类上定义的路径作为公共的前缀。全局统一定义
+>
+
+### SpringMvc 方法的参数类型
+
+> 这里说的SpringMvc 方法一般就是指在controller层里,被各种@xxxMapping注解修饰的方法,比如查询所有学生方法,删除学生信息方法
+
+1.可以是HttpServletRequest,HttpServletResponse,HttpSession
+
+```java
+ public String list(Map map,
+ HttpServletRequest request) {
+
+```
+2.可以是基本数据类型,以及包装类,BigDecimal,BigInteger,String,用于接收请求中的参数
+
+```java
+ public String list(Map map,int pages,int limit ,String order) {
+```
+
+如果前端url里写的sort=id,但后端就是想用order接收,那么
+搭配@RequestParam ,@PathVariable注解
+
+```java
+ public String list(Map map,
+ int pages,int limit ,
+ @RequestParam("sort") String order) {
+```
+
+> @RequestParam("sort")还可以加默认值,也就是@RequestParam("sort",defaultValue ="name")
+
+```java
+ @GetMapping(value = "/list/{limit}",produces = MediaType.TEXT_HTML_VALUE)
+ public String list(Map map,
+ int pages,
+ @PathVariable Integer limit ,
+ @RequestParam("sort") String order) {
+```
+
+
+
+> url里list/后写15,此时的15会直接赋给带有 @PathVariable注解且名字为limit的变量
+
+```java
+@GetMapping(value = "/list/{a1}",produces = MediaType.TEXT_HTML_VALUE)
+ public String list(Map map,
+ int pages,
+ @PathVariable("a1") Integer limit ,
+ @RequestParam("sort") String order) {
+```
+
+> @PathVariable也可以指定名字,如 @PathVariable("a1")
+```java
+@GetMapping(value ={"/list/{a1}","/list"},produces = MediaType.TEXT_HTML_VALUE)
+ public String list(Map map,
+ int pages,
+ @PathVariable("a1") Integer limit ,
+ @RequestParam("sort") String order) {
+```
+> 如果加上required = false,也就是 @PathVariable("a1",required =
+> false)代表url里list/后可以不写{a1}
+
+3.JavaBean 普通类将请求参数通过反射,设置到javabean实例中
+
+```java
+ public String list(Map map,
+ Student student) {
+```
+
+
+
+
+4.Map,Model,ModelMap:充当请求域,map最常用
+
+```java
+ public String list(Map map,
+ Model model,ModelMap modelMap ) {
+ List students = studentService.findAll();
+ map.put("students", students);
+ model.addAttribute("students",students);
+
+ modelMap.addAttribute("modelMap",students);
+ modelMap.put("students",students);
+
+
+```
+
+5.加了@RequestParam的map不再作为请求域而是用于存储请求参数
+
+```java
+ public String list(Map map,
+ @RequestParam Map map1 ) {
+ System.out.println(map1);
+```
+
+
+
+以上五种参数任意组合
+
+### SpringMvc 方法的返回值
+1.字符串且响应内容类型为text/html,返回值即模板文件名
+比如:
+```java
+ //请求转发
+ return "/student/list";
+```
+
+2.在满足1的基础上,返回"forword:/xxx"表示请求转发
+
+```java
+ return "forward:/student/list";
+```
+
+3.在满足1的基础上,返回“redirect:/xxx”表示重定向
+
+```java
+ return "redirect:/student/list";
+```
+
+4.ModelAndView:既可以指定视图名称,同时可以当请求域使用,前三种本质上也会被包装成ModelAndView
+
+```java
+ @GetMapping("/to_list")
+ public ModelAndView toList(){
+
+ ModelAndView mav = new ModelAndView("student/list");//做视图
+ mav.addObject("students",studentService.findAll());//做模型
+ return mav;
+
+ }
+```
+
+5.如果指定了响应内容类型为json,并且添加了@ResponseBody注解,无论返回值什么类型,都会序列化成json字符串
+
+```java
+//响应json内容
+ @GetMapping(value = "/student/list_json",produces = MediaType.APPLICATION_JSON_VALUE)
+ @ResponseBody
+ public ResponseEntity> list(){
+ return "student/list"
+ }
+```
+
+6.返回ResponseEntity类型。仅限于响应json格式,同时封装了业务数据以及状态码
+
+```java
+ //响应json内容
+ @GetMapping(value = "/student/list_json",produces = MediaType.APPLICATION_JSON_VALUE)
+ @ResponseBody
+ public ResponseEntity> list(){
+ List students = studentService.findAll();
+ return ResponseEntity.status(200).body(students);
+ }
+```
