SpringBoot+Mybatis-plus+knife4j项目的搭建

SpringBoot项目搭建

搭建一个简单的SpringBoot项目，主要是knife4j的测试接口的页面比较好看。

1、配置文件

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/qing
    username: root
    password: root


mybatis:
  mapper-locations: classpath:mapper/*.xml
# 现在这个日志交给mybatis来管理了需要替换
#  configuration:
#    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

2、配置信息

2.1后端跨域配置

@Configuration
public class CorsConfig {

    // 当前跨域请求最大有效时长。这里默认1天
    private static final long MAX_AGE = 24 * 60 * 60;

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*"); // 1 设置访问源地址
        corsConfiguration.addAllowedHeader("*"); // 2 设置访问源请求头
        corsConfiguration.addAllowedMethod("*"); // 3 设置访问源请求方法
        corsConfiguration.setMaxAge(MAX_AGE);
        source.registerCorsConfiguration("/**", corsConfiguration); // 4 对接口配置跨域设置
        return new CorsFilter(source);
    }
}

2.2mybatis-plus的配置

@Configuration
@MapperScan("com.atwjw.mapper")
public class MybatisPlusConfig {

    /**
     * 添加分页插件
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));//如果配置多个插件,切记分页最后添加
        //interceptor.addInnerInterceptor(new PaginationInnerInterceptor()); 如果有多数据源可以不配具体类型 否则都建议配上具体的DbType
        return interceptor;
    }
}

2.3knife4j的配置

@Configuration
@EnableSwagger2WebMvc
public class SwaggerConfig {

    private ApiInfo apiInfo(String title, String description, String version) {
        return new ApiInfoBuilder()
                .title(title)
                .description(description)
                .version(version)
                .build();
    }

    @Bean
    public Docket userDocket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("用户管理")
                .apiInfo(apiInfo("用户管理 API", "包括用户的增删改查等操作", "1.0"))
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.atwjw"))
                .paths(PathSelectors.ant("/user/**"))
                .build();
    }

    @Bean
    public Docket productDocket() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("产品管理")
                .apiInfo(apiInfo("产品管理 API", "包括产品的增删改查等操作", "1.0"))
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.atwjw"))
                .paths(PathSelectors.ant("/product/**"))
                .build();
    }
}

3、 代码生成器的配置

public class CodeGenerator {

    public static void main(String[] args) {
        generate();
    }

    private static void generate() {
        FastAutoGenerator.create("jdbc:mysql://localhost:3306/qing?serverTimezone=GMT%2b8", "root", "root")
                .globalConfig(builder -> {
                    builder.author("wjw") // 设置作者
                            .enableSwagger() // 开启 swagger 模式
                            .fileOverride() // 覆盖已生成文件
                            .outputDir("D:\\JavaUtils\\idea\\IdeaWorkplace\\StudyCode\\SpringBoot-Mybatis-plus\\src\\main\\java\\"); // 指定输出目录D:\JavaUtils\idea\IdeaWorkplace\StudyCode\SpringBoot-Mybatis-plus\src\main\java
                })
                .packageConfig(builder -> {
                    builder.parent("com.atwjw") // 设置父包名
                            .moduleName(null) // 设置父包模块名
                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml, "D:\\JavaUtils\\idea\\IdeaWorkplace\\StudyCode\\SpringBoot-Mybatis-plus\\src\\main\\resources\\mapper\\")); // 设置mapperXml生成路径D:\JavaUtils\idea\IdeaWorkplace\StudyCode\SpringBoot-Mybatis-plus\src\main\resources\mapper
                })
                .strategyConfig(builder -> {
                    builder.entityBuilder().enableLombok();
//                    builder.mapperBuilder().enableMapperAnnotation().build();
                    builder.controllerBuilder().enableHyphenStyle()  // 开启驼峰转连字符
                            .enableRestStyle();  // 开启生成@RestController 控制器
                    builder.addInclude("sys_role") // 设置需要生成的表名
                            .addTablePrefix("t_", "sys_"); // 设置过滤表前缀
                })
//                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();

    }
}
