idea创建多模块springboot项目(springboot多模块项目)

1 Springboot多模块开发总结

1.1 创建新项目1.2 在项目中添加模块

1.2.1 springboot-common模块 1.2.2 springboot-domain模块1.2.3 springboot-service模块1.2.4 springboot-web模块

springboot-high

springboot-common 公共模块 (DTO)springboot-domain 域模块（entity）（领域模型,完成实体类和表的映射）springboot-service 业务模块

一般一个项目，几十个模块，大模块下面有小模块，小模块下面有类和方法。

父模块不需要打包，设置内容为pom

1.引入依赖；模块中不需要进行源代码开发，所以删除src文件夹
2.new Mudule，添加三个新模块，springboot-common/domain/service
groupId: com.qfy.springboot.common/domain/service

添加Swagger配置

    
        io.springfox
        springfox-boot-starter
        ${project.swagger.version}
    

添加Swagger配置类SwaggerConfiguration

package com.qfy.springboot.common.config;

import io.swagger.v3.oas.annotations.Operation;
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.service.Contact;
import springfox.documentation.spi.documentationType;
import springfox.documentation.spring.web.plugins.Docket;


@Configuration
public class SwaggerConfiguration {

    public Docket createRestApi() {
        return new Docket(documentationType.OAS_30)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.withMethodAnnotation(Operation.class))
                .paths(PathSelectors.any())
                .build();
    }


    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("springboot整合swagger3的接口文档")
                .description("描述图书管理的接口文档")
                .contact(new Contact("非凡boot", "http://www.diyt.com", "dyit@dyit.com"))
                .version("1.0")
                .build();
    }
}

DTO注解

package com.dyit.springboot.common.dto;

import io.swagger.v3.oas.annotations.media.Schema;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.util.Date;
@Schema(description = "DTO")
@Data
@NoArgsConstructor
@AllArgsConstructor
public class HttpResp {
    @Schema(description = "代码和描述")
    RespEnum resp;
    @Schema(description = "返回结果")
    private Object results;
    @Schema(description = "DTO对象创建的时间")
    private Date date;
}

package com.dyit.springboot.common.dto;

import io.swagger.v3.oas.annotations.media.Schema;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.util.Date;
@Schema(description = "DTO")
@Data
@NoArgsConstructor
@AllArgsConstructor
public class HttpResp {
    @Schema(description = "代码和描述")
    RespEnum resp;
    @Schema(description = "返回结果")
    private Object results;
    @Schema(description = "DTO对象创建的时间")
    private Date date;
}
