springboot项目初始化--mybatisplus代码生成和swagger配置

1. mybatis代码生成，这里我使用加了两个数据库的表user和student作为测试表

添加依赖

 <!--代码自动生成器-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.5.1</version>
        </dependency>
        <!--freemarker模板-->
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>2.3.28</version>
        </dependency>
        <!--velocity模板-->
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.3</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.27</version>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.2</version>
        </dependency>

写properties文件（后面测试代码用）

server.port=8083
#数据库配置
spring.datasource.name=imocc_mall_datasource
spring.datasource.username=root
spring.datasource.password=123123
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/db1?serverTimezone=Asia/Shanghai
#mybatis.mapper-locations= classpath:mappers/*.xml

代码生成类（启动它就可以生成代码啦！！）

package com.example.demo;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

/**

public class AutoGenerator {

    private static final String url = "jdbc:mysql://localhost:3306/db1?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8";
    private static final String username = "root";
    private static final String password = "123123";

    public static void main(String[] args) {
        List<String> tables = new ArrayList<>();
        tables.add("student"); //数据库表名称，一个user表一个student表
        tables.add("user");

        FastAutoGenerator.create(url, username, password)
                .globalConfig(builder -> {
                    builder.author("wangle")               //作者
                            .outputDir(System.getProperty("user.dir") + "\\src\\main\\java")    //输出路径(写到java目录)
                            .enableSwagger()           //开启swagger
                            .commentDate("yyyy-MM-dd")
                            .fileOverride();            //开启覆盖之前生成的文件

                })
                .packageConfig(builder -> {
                    builder.parent("com.example")    //这里修改你的包名
                            .moduleName("demo")
                            .entity("entity")
                            .service("service")
                            .serviceImpl("service.serviceImpl")
                            .controller("controller")
                            .mapper("mapper")
                            .xml("mapper")
                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml, System.getProperty("user.dir") + "\\src\\main\\resources\\mapper"));
                })
                .strategyConfig(builder -> {
                    builder.addInclude(tables)
                            .addTablePrefix("p_")
                            .serviceBuilder()
                            .formatServiceFileName("%sService")
                            .formatServiceImplFileName("%sServiceImpl")
                            .entityBuilder()
                            .enableLombok()
                            .logicDeleteColumnName("deleted")
                            .enableTableFieldAnnotation()
                            .controllerBuilder()
                            .formatFileName("%sController")
                            .enableRestStyle()
                            .mapperBuilder()
                            .enableBaseResultMap()  //生成通用的resultMap
                            .superClass(BaseMapper.class)
                            .formatMapperFileName("%sMapper")
                            .enableMapperAnnotation()
                            .formatXmlFileName("%sMapper");
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
}

2. swagger添加

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>

配置类

package com.example.demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
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;

@Configuration
public class SpringFoxConfig {

    //访问http://localhost:8083/swagger-ui.html可以看到API文档
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("测试mybatisplus")
                .description("")
                .termsOfServiceUrl("")
                .build();
    }
}

添加注解到启动类

@EnableSwagger2
@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}
