一、创建工程
二、配置工程
1.配置文件application.properties
#启动端口
server.port=8080
#应用名称
spring.application.name=form
###数据源配置
#mybatis配置
mybatis.mapper-locations=/mappers/*.xml
#数据源配置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/form?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=5209365
#日志配置，打开mybatis操作日志
logging.level.net.csdn.springboot.form.dao: debug
2.修改pom.xml文件，增加常用的依赖?
<?xml version="1.0" encoding="UTF-8"?>

四、重要知识
1.允许跨域
在前后端分离的项目中，由于前后端是分开的，ip和端口有可能不会一样，因此需要配置允许跨域，这样前端才能访问到后端的接口。
/**
* 跨域配置
*/
@Configuration
public class CorsConfig {
@Bean
public FilterRegistrationBean<CorsFilter> corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", buildConfig());
CorsFilter corsFilter = new CorsFilter(source);
FilterRegistrationBean<CorsFilter> filterRegistrationBean = new FilterRegistrationBean<>();
filterRegistrationBean.setFilter(corsFilter);
filterRegistrationBean.setOrder(0);
return filterRegistrationBean;
}
private CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
// 1允许任何域名使用
corsConfiguration.addAllowedOrigin("*");
// 2允许任何头
corsConfiguration.addAllowedHeader("*");
// 3允许任何方法（post、get等）
corsConfiguration.addAllowedMethod("*");
return corsConfiguration;
}
}2.swagger使用
