SpringBoot知识02

1、快速生成mapper和service（简单的单表）

2、springboot配置swagger（路径不用加/api）

（1）主pom导包（子pom要引用，可选依赖）

<!--            swagger3用-->
            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-boot-starter</artifactId>
                <version>3.0.0</version>
            </dependency>
            <dependency>
                <groupId>com.github.xiaoymin</groupId>
                <artifactId>knife4j-spring-boot-starter</artifactId>
                <version>3.0.3</version>
            </dependency>

（2）配置swagger和mvc

server:
  port: 8081


spring:
#  swagger使用
  mvc:
    path-match:
      matching-strategy: ant_path_matcher
  datasource:
    # 指定连接池的类型
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      url: "jdbc:mysql://localhost:3306/mybatis?characterEncoding=UTF-8&useSSL=false&useUnicode=true&serverTimezone=Asia/Shanghai"
      username: "root"
      password: "lht660036"
      max-active: 20
      # ???
      # wall  ??druid ???
      # stat  ??druid?????
      filters: "wall,slf4j,stat"
      web-stat-filter:
        enabled: true
        url-pattern: /*
        # ??????????
        exclusions: "/druid,*.png"
        # ???????
      stat-view-servlet:
        enabled: true
        url-pattern: "/druid/*"
        reset-enable: true
        login-username: admin
        login-password: admin


mybatis:


  # ??mapper.xml
  mapper-locations: "classpath*:mapper/**/*.xml"
  #  ???
  type-aliases-package: "com.lht.project.data.mybatis.entity"


swagger:
  base-package: "com.lht.project.data.mybatis.controller"
  title: "京东商城在线Api文档"
  group-name: "订单商城"
  description: "出现bug，请熟读该文档"

  name: "刘惠棠帅哥"
  url: "https://www.baidu.com"
  email: "11111@163.com"
  version: "1.0.0"

（3）定义swaggerProperties

package com.lht.project.data.mybatis.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties("swagger")
@Data
public class SwaggerProperties {
    private String title;
    private String basePackage;
    private String groupName;
    private String description;

    private String name;
    private String url;
    private String email;

    private String version;

}

（4）定义swaggerConfig

package com.lht.project.data.mybatis.config;

import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.oas.annotations.EnableOpenApi;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import javax.annotation.Resource;

@Configuration
@EnableOpenApi
public class SwaggerConfig {

    @Resource
    private SwaggerProperties swaggerProperties;

    @Bean
    public Docket docket(ApiInfo apiInfo){
        return new Docket(DocumentationType.OAS_30).apiInfo(apiInfo)
                .groupName(swaggerProperties.getGroupName())
                .select()
                .apis(RequestHandlerSelectors.basePackage(swaggerProperties.getBasePackage()))
                .paths(PathSelectors.any())
                .build();
    }

    @Bean
    public ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title(swaggerProperties.getTitle())
                .description(swaggerProperties.getDescription())
                .version(swaggerProperties.getVersion())
                .contact(new Contact(swaggerProperties.getName(), swaggerProperties.getUrl(), swaggerProperties.getEmail()))
                .build();
    }
}

（5）controller调用
