人脸识别系统【从0到1完成一个小项目】【6】【springboot快速上手】

1.父类

在pom.xml里面添加如上代码，有些会自动生成，没有生成的添加一下

<parent>
        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>2.7.6</version>
</parent>

2.热部署
热部署完毕每次修改代码会自动加载生效，但是有时候并不一定生效，之前遇到过的，所以如果遇到修改代码后不生效，重启下项目
在pom.xml里面添加如下代码

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
</dependency>

在application.properties里面配置devtools

#热部署生效
spring.devtools.restart.enables = true
#设置重启目录
spring.devtools.restart.additional-paths=src/main/java
#设置classpath目录下的WEB-INF文件夹内容修改不重启
spring.devtools.restart.additional-exclude=static/**

IntelliJ IDEA需要修改下面的设置

按住ctrl+shift+alt+/,选择register,勾选自动编译

配置完后重启项目，使之生效
3.端口修改
在application.properties里面添加如下代码，并修改为想要的端口号

4.Swagger接口
相当于接口文档，动态生成，如果是多个人做项目，方便相互之间交流
在pom.xml里面添加如下依赖

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

在项目下新建config文件夹，里面创建SwaggerConfig，添加如下内容

public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com"))
                .paths(PathSelectors.any()).build();
    }
    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title("人脸识别项目api")
                .description("人脸识别")
                .build();
    }

配置成功在浏览器输入http://localhost:8080/swagger-ui.html就可以看到如下页面

5.完整的pom.xml
其实遇到挺多问题的，版本不匹配，头秃，，，，现在终于好了，啊啊啊啊啊啊
为了让大家少走弯路，节约时间，放一下完整的pom.xml
