二、JSR303数据校验及多环境切换

  1. 配置文件加载位置

三、SpringBoot Web开发

自动装配：

SpringBoot到底帮我们配置了什么？我们能不能进行修改？能修改哪些东西？能不能扩展？

  • xxxAutoConfiguration…向容器中自动配置组件
  • xxxProperties：自动配置类，装配配置文件中自定义的一些内容

要解决的问题：

  • 导入静态资源…

  • 首页

  • jsp, 模板引擎Thymeleaf

    thymeleaf依赖

  • 装配扩展SpringMVC

  • 增删改查

  • 拦截器

  • 国际化

四、员工管理系统

  1. 首页配置
    1. 注意点，所有页面的静态资源都需要使用thymeleaf接管；（导入thymeleaf依赖）
    2. url: @{}
  2. 页面国际化
    1. 我们需要配置i18n文件
    2. 我们如果需要在项目中进行按钮自动切换，我们需要自定义一个组件LocaleResolver
    3. 记得将自己写的组件配置到spring容器@Bean
    4. #{}

五、整合MyBatis

整合包

mybatis-spring-boot-starter

  1. 导入包

    <span style="color:#000000"><code class="language-xml"><span style="color:#5c6370"><!--引入mybatis,这是Mybatis官方提供的适配SpringBoot的，而不是SpringBoot自己的--></span>

</code></span>

  2. 配置yml文件

    application.yml

    <span style="color:#000000"><code class="language-yml"><span style="color:#5c6370"># 配置spring自带的数据源</span>

</code></span>

  3. mybatis配置

    • User

      <span style="color:#000000"><code class="language-java"><span style="color:#999999">@Data</span>
<span style="color:#999999">@AllArgsConstructor</span>
<span style="color:#999999">@NoArgsConstructor</span>

</code></span>

  4. 编写sql

  5. service层调用dao层

    • UserService 接口

      <span style="color:#000000"><code class="language-java"><span style="color:#c678dd">public</span> <span style="color:#c678dd">interface</span> UserService <span style="color:#999999">{</span>
    <span style="color:#c678dd">public</span> User <span style="color:#61aeee">queryUserByName</span><span style="color:#999999">(</span>String name<span style="color:#999999">)</span><span style="color:#999999">;</span>
<span style="color:#999999">}</span>
</code></span>

    • UserServiceImpl实现类

      <span style="color:#000000"><code class="language-java"><span style="color:#999999">@Service</span>
<span style="color:#c678dd">public</span> <span style="color:#c678dd">class</span> UserServiceImpl <span style="color:#c678dd">implements</span> UserService<span style="color:#999999">{</span>

</code></span>

六、SpringSecurity

  1. 引入 Spring Security 模块

  2. 编写 Spring Security 配置类

    参考官网：https://spring.io/projects/spring-security

  3. 编写基础配置类

    • 定制请求的授权规则
    • 定义认证规则

八、Swagger

学习目标：

  • 了解Swagger的作用和概念
  • 了解前后端分离
  • 在SpringBoot中集成Swagger

一、 Swagger简介

前后端分离时代：

  • 后端：后端控制层，服务层，数据访问层
  • 前端：前端控制层，视图层

Swagger :

  • 号称世界上最流行的API框架；
  • RestFul Api文档在线自动生成工具 => Api文档与Api定义同步更新
  • 直接运行，可以在线测试API接口
  • 支持多种语言：（Java , Php…）

在项目中使用Swagger需要Springbox

  • swagger2
  • ui

二、SpringBoot集成Swagger

  1. 新建一个SpringBoot - web 工程

  2. 导入相关依赖

五、 接口注释

狂神说java --springboot笔记
总结：

  1. 我们可以通过Swagger给一些比较难理解的属性或者接口，增加注释信息；
  2. 接口文档实时更新
  3. 可以在线测试

Swagger是一个优秀的工具，几乎所有的大公司都有使用它

【注意点】在正式发布的时候，关闭Swagger！！出于安全考虑，而且节省运行的内存。

九、任务

一、异步任务

  1. 给要实现异步任务加上注解 @Async

三、定时任务

  1. TaskScheduler 任务调度者
  2. TaskExecutor 任务执行者
  3. @EnableScheduling 开启定时功能的注解
  4. @Scheduled 什么时候执行
  5. Cron表达式

  1. 编写定时服务

    <span style="color:#000000"><code class="language-java"><span style="color:#999999">@Service</span>
<span style="color:#c678dd">public</span> <span style="color:#c678dd">class</span> ScheduledService <span style="color:#999999">{</span>

    <span style="color:#5c6370">//在一个特定的时间执行这个方法</span>

    <span style="color:#5c6370">//cron 表达式</span>
    <span style="color:#5c6370">//秒 分 时 日 月 周几</span>

    <span style="color:#5c6370">/*
        30 17 17 * * ?  每天10点15分30 执行一次
        30 0/5 10,18 * * ?  每天10点和18点，每隔五分钟执行一次
    */</span>

    <span style="color:#999999">@Scheduled</span><span style="color:#999999">(</span>cron <span style="color:#669900">=</span> <span style="color:#669900">"30 17 17 * * ?"</span><span style="color:#999999">)</span>
    <span style="color:#c678dd">public</span> <span style="color:#c678dd">void</span> <span style="color:#61aeee">Hello</span><span style="color:#999999">(</span><span style="color:#999999">)</span><span style="color:#999999">{</span>
        System<span style="color:#999999">.</span>out<span style="color:#999999">.</span><span style="color:#61aeee">println</span><span style="color:#999999">(</span><span style="color:#669900">"hello,被执行了!"</span><span style="color:#999999">)</span><span style="color:#999999">;</span>
    <span style="color:#999999">}</span>

<span style="color:#999999">}</span>
</code></span>

  2. 在启动类开启定时功能

    <span style="color:#000000"><code class="language-java"><span style="color:#999999">@EnableAsync</span> <span style="color:#5c6370">// 开启异步注解功能</span>
<span style="color:#999999">@EnableScheduling</span> <span style="color:#5c6370">//开启定时功能的注解</span>
<span style="color:#999999">@SpringBootApplication</span>

    <span style="color:#999999">}</span>
<span style="color:#999999">}</span>
</code></span>

十、整合Redis

单独整理

十一、分布式Dubbo + Zookeeper

zookeeper ：注册中心

dubbo-admin : 监控管理后台，查我们注册了哪些服务，哪些服务被消费了

Dubbo：jar包

步骤：

前提：zookeeper服务已启动

  1. 提供者提供服务

    • 导入依赖

    • 配置注册中心的地址，以及服务发现名，和要扫描的包

      狂神说java --springboot笔记

    • 在想要被注册的服务上面，再增加一个注解**@Service**（dubbo包下的）

  2. 消费者如何消费

    • 导入依赖

    • 配置注册中心的地址，配置自己的服务名
      狂神说java --springboot笔记

    • 从远程注入服务 @Reference

回顾总结：三层架构   + MVC

  架构 -->  解耦

    开发框架：

                   Spring：

                        Ioc（控制反转）  + Aop（面向切面编程）[本质：动态代理]

               Ioc（控制反转）

                     以前自己是new 对象，现在交给spring ioc容器统一管理，我们需要什么直接去拿  ioc容器就像是一个对象工厂，把对象交给工厂，工程管理对象的创建以及依赖关系，我们需要的时候直接去工厂中获取   

                    [控制反转，依赖注入]   控制反转：是一种思想，原本自己控制的事情，交给ico控制  ，依赖注入是控制反转的实现方式【对象】无需自行创建或者管理依赖关系，依赖关系将被自动注入到需要他们的对象当中

                    ：将对象统一管理  ：降低耦合

            Aop（面向切面编程）[本质：动态代理]

                  解决非业务代码抽取的问题，底层是动态代理，在spring内实现依赖是BeanPostProcessor ，在方法前后增加非业务代码

      spring是轻量型的java的开源框架，容器

负载均衡

微服务架构存在的问题:

  • 分布式架构会遇到的四个核心问题
  • 这么多服务，客户端该如何去访问
  • 这么多服务，服务之间如何进行通信
  • 这么多服务，如何管理
  • 服务挂了，该怎么办

==》 解决方案：

​ SpringCloud，是一套生态，就是用来解决以上分布式架构的4个问题。

​ 想使用SpringCloud，必须掌握SpringBoot，因为SpringCloud是基于SpringBoot的

1. API网关，服务路由
2. HTTP，RPC框架，异步调用
3. 服务注册与发现，高可用
4. 熔断机制，服务降级</code></span>
