### Reference Documentation

For further reference, please consider the following sections:

* [Official Apache Maven documentation](https://maven.apache.org/guides/index.html)
* [Spring Boot Maven Plugin Reference Guide](https://docs.spring.io/spring-boot/docs/2.5.0/maven-plugin/reference/html/)
* [Create an OCI image](https://docs.spring.io/spring-boot/docs/2.5.0/maven-plugin/reference/html/#build-image)

##依赖热更新

1.File->settings->Build,Execution,Deployment->Compiler->Build project Automatically
2.Ctrl+shift+alt+/  激活面板 Registry ->compiler.automake.allow.when.app.running

##注解：
@ConfigurationProperties   批量注入Bean
@Value                     单属性注入，需要spEL表达式

##多环境打包：
java -jar 路径 --spring.profiles.active=dev/prod/test

##配置文件生成随机数
${random.value}
${random.int}
${random.long}
${random.uuid}
${random.int(10)}
${random.int[1024,4096]}

##mysql配置
进入https://dev.mysql.com/downloads/mysql/下载，然后配置环境变量，设置密码为123456

##开启mybatis驼峰命名
mybatis:
configuration:
map-underscore-to-camel-case: true

##文件下载
1.ResponseEntity
2.commons.io包下的FileUtil
3.文件名需要中文时，使用URLEncoder.encode("","UTF-8");这个思路去处理

##打包方式
1.打包形式切换 -> pom.xml -> 输入packaging标签以切换打包方式
2.打包war包时
<!--   -->
    <dependency>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-tomcat</artifactId>
     </dependency>
3.application主类配置
<!--   -->
    @ServletComponentScan
    @SpringBootApplication
    public class SpringJavaMavenApplication2 extends SpringBootServletInitializer {
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            return builder.sources(SpringJavaMavenApplication2.class);
        }

        public static void main(String[] args) {
            SpringApplication.run(SpringJavaMavenApplication2.class, args);
            System.out.println("hello");
        }
    }
4.maven -> package  得到war包
5.下载apache-tomcat -> https://blog.csdn.net/weixin_43873620/article/details/89930803
6.apache-tomcat 8.5.32下webapps下    war包粘贴到这个目录中
7.回到webapps的上一级目录打开bin找到startup.bat双击启动tomcat，如果没有报错，回到webapps的文件下会发现war包被解压生成了一个新的文件
8.去访问 http://localhost:8080/war包生成文件夹的名字/注解上的路径  查看结果


##redis安装步骤
1.打开 https://github.com/microsoftarchive/redis/releases
找到3.2.100版本号下Redis-x64-3.2.100.zip下载解压到自定义目录，不需要额外配置
