1：前提准备
-
准备开发工具：idea
-
java环境：jdk1.8
-
安装插件lombook
2：创建springboot项目流程
-
依次选择：File–>New–>Project…
-
选择Spring Initializr,依次填写和修改响应信息。
-
由于官网地址可能因为网络等原因，会有问题，可以修改下镜像
https://start.aliyun.com
-
填写好之后，点击：next
-
选择版本和对应的依赖，确认无误点击：finish
-
创建完成的目录结构
-
修改application.priperties文件的后缀改成yml
-
添加基础的三层架构包，删除demos
控制层：controller
业务逻辑层：service、impl
数据访问层/持久层：mapper
实体：entity
- application.yml 文件添加内容
spring:application:# 服务名称name: fallrain-bootprofiles:# 选择环境，我这里创建了两个环境文件，dev：开发环境，prod: 正式发布环境# 正常有这么几个环境# 1：dev--本地开发环境；# 2：sit--测试环境；# 3：uat--准生产环境；# 4：prod--生产环境；active: devmvc:pathmatch:matching-strategy: ant_path_matcher
mybatis:# 配置mapper.xml位置mapper-locations: classpath:mapper/**.xml
- application-dev.yml 文件添加内容
server:# 服务启动端口，可根据情况自定义port: 8989
spring:# 数据库连接datasource:type: com.alibaba.druid.pool.DruidDataSourcedriver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://127.0.0.1:3306/fallrain_boot?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&autoReconnect=true&allowMultiQueries=trueusername: rootpassword: admin@123
swagger:# 是否开启swaggerenable: true-

启动项目
3：集成阿里连接池步骤
- 添加依赖
<!-- 阿里云连接池 --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>${druid.version}</version></dependency>
<druid.version>1.2.16</druid.version>
4：集成swagger方便测试
- 引入依赖,放在阿里连接池下面就行
<!-- Swagger API文档 --><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.9.2</version><exclusions><exclusion><groupId>io.swagger</groupId><artifactId>swagger-annotations</artifactId></exclusion><exclusion><groupId>io.swagger</groupId><artifactId>swagger-models</artifactId></exclusion></exclusions></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.9.2</version></dependency><dependency><groupId>com.github.xiaoymin</groupId><artifactId>swagger-bootstrap-ui</artifactId><version>1.9.6</version></dependency><!-- # 增加两个配置解决 NumberFormatException --><dependency><groupId>io.swagger</groupId><artifactId>swagger-annotations</artifactId><version>1.5.22</version></dependency><dependency><groupId>io.swagger</groupId><artifactId>swagger-models</artifactId><version>1.5.22</version></dependency><!-- Swagger API文档 -->
- 创建配置类：Swagger2Config
package com.fallrain.fallrainspringboot.swagger;import com.github.xiaoymin.swaggerbootstrapui.annotations.EnableSwaggerBootstrapUI;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;/*** @Decription SWAGGER*/
@Slf4j
@Configuration
@EnableSwagger2
@EnableSwaggerBootstrapUI
@ConditionalOnProperty(name = "swagger.enable", havingValue = "true")
public class Swagger2Config implements WebMvcConfigurer {/**** 显示swagger-ui.html文档展示页，还必须注入swagger资源：** @param registry*/@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");registry.addResourceHandler("doc.html").addResourceLocations("classpath:/META-INF/resources/");registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");}/*** swagger2的配置文件，这里可以配置swagger2的一些基本的内容，比如扫描的包等等** @return Docket*/@Beanpublic Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select()//此包路径下的类，才生成接口文档.apis(RequestHandlerSelectors.basePackage("com.fallrain.fallrainspringboot"))//加了ApiOperation注解的类，才生成接口文档.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).paths(PathSelectors.any()).build();
// .securitySchemes(Collections.singletonList(securityScheme()));//.globalOperationParameters(setHeaderToken());}/*** api文档的详细信息函数,注意这里的注解引用的是哪个** @return*/private ApiInfo apiInfo() {return new ApiInfoBuilder()// //大标题.title("XX项目-XX管理-API接口文档")// 版本号.version("1.0")
// .termsOfServiceUrl("NO terms of service")// 描述.description("后台API接口")// 作者.contact("XXX团队").license("The Apache License, Version 2.0").licenseUrl("http://www.apache.org/licenses/LICENSE-2.0.html").build();}}- 注意事项：包路径记得修改
.apis(RequestHandlerSelectors.basePackage(“com.fallrain.fallrainspringboot”))
- yml文件配置是否开启swagger
swagger:# 是否开启swaggerenable: true
5：书写增删改查进行测试
- 引入lombok依赖
<dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.16</version></dependency>
- 书写增删改查
- 测试：http://localhost:8989/doc.html
6：项目gitee地址
