项目的多模块构建

总项目

总项目是一个空的盒子，放置其他的模块

其他模块需要时，可以导入

模块构建

构建模块：添加model

设置groupId

放后端的相关

放前端的代码，占位

问题：如果删除

先删除模块，再删除文件，然后删一下pom的引用

依赖引入

lombok通用

maven的基础原则:

A模块: B模块, C模块

book-market下面的子模块继承 book-market

父模块定义的 子模块自动继承

    <parent>
        <groupId>com.tianju.bmgroupId>
        <artifactId>book-market-v1.1artifactId>
        <version>1.0-SNAPSHOTversion>
    parent>

模块

common模块，都要用

    <dependencies>
        <dependency>
            <groupId>com.github.xiaoymingroupId>
            <artifactId>knife4j-openapi2-spring-boot-starterartifactId>
            <version>4.0.0version>
        dependency>
    dependencies>

比如允许跨域放到common模块中

配置application

# 项目中可以使用Swagger做接口测试
knife4j:
  enable: true

mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

domain模块，实体类相关

    <dependencies>

        <dependency>
            <groupId>com.tianju.bm.commongroupId>
            <artifactId>bm-commonartifactId>
            <version>1.0-SNAPSHOTversion>
        dependency>


        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
        dependency>

        <dependency>
            <groupId>com.alibabagroupId>
            <artifactId>druid-spring-boot-starterartifactId>
            <version>1.2.18version>
        dependency>
    dependencies>

引入上面设置好的common模块

实体类相关，设置一下数据库的连接

配置application

spring:
  datasource:
    druid:
      url: jdbc:mysql://127.0.0.1:3306/book_db?useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true
      username: root
      password: 123
      driver-class-name: com.mysql.cj.jdbc.Driver

book模块，主模块

引入common和domain模块

    <dependencies>
        <dependency>
            <groupId>com.tianju.bm.domaingroupId>
            <artifactId>bm-domainartifactId>
            <version>1.0-SNAPSHOTversion>
        dependency>
    dependencies>

激活一下domain模块和common模块

server:
  port: 9098
logging:
  level:
    com.tianju.bm: debug
spring:
  profiles:
    #引用application-common,applicaiton-domain配置
    active: common,domain

运行测试

http://localhost:9098/doc.html

接口测试工具

https://apifox.com/

swagger2，较多

swagger3，

Knife4j

Knife4j的前身是swagger-bootstrap=ui,前身swagger–bootstrap-ui是一个纯swagger–ui的ui皮肤项目

https://doc.xiaominfo.com/docs/quick-start

1.引入依赖

        <dependency>
            <groupId>com.github.xiaoymingroupId>
            <artifactId>knife4j-openapi2-spring-boot-starterartifactId>
            <version>4.1.0version>
        dependency>

底层就是swagger

2.配置

knife4j:
  enable: true

3.常用注解

import io.swagger.annotations.Api;

序号	注解	作用
1	@Api(tags = “图书的api接口类”)	左侧名字
2	@ApiOperation(“findPage方法测试”)	get方法名字
3	@ApiImplicitParam(name = “findByPage”,value = “分页查询”,required = true)	参数相关
4	@ApiModel(“DTO返回数据”)	写在HttpResp实体类上
5	@ApiModelProperty(“time”)	写在HttpResp类属性上

BookController.java文件

package com.tinaju.bm.controller;

import com.tinaju.bm.dto.HttpResp;
import com.tinaju.bm.dto.ResultCode;
import com.tinaju.bm.entity.Book;
import com.tinaju.bm.service.IBookService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.Date;
import java.util.List;

@Api(tags = "图书的api接口类")
@RestController
@RequestMapping("/api/book")
public class BookController {
    @Autowired
    private IBookService bookService;

    @ApiOperation("findPage方法测试")
    @ApiImplicitParam(name = "findByPage",value = "分页查询",required = true)
    @GetMapping("/findByPage")
    public HttpResp findByPage(int currentPage){
        List<Book> bookList = bookService.findByPage(currentPage, 5);
        return HttpResp.results(ResultCode.BOOK_SUCCESS,new Date(),bookList);
    }
}

HttpResp.java返回给前端的实体类

package com.tinaju.bm.dto;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.*;

import java.io.Serializable;
import java.util.Date;

/**
 * 返回给前端的响应
 * @param 
 */
@ApiModel("DTO返回数据")
@Getter@Setter
@ToString
public class HttpResp<T> implements Serializable {

    private ResultCode resultCode;
    @ApiModelProperty("time")
    private Date time;
    @ApiModelProperty("results")
    private T results;

    private HttpResp(){}

    public static <T> HttpResp<T> results(ResultCode resultCode,Date time,T results){ // java泛型的写法
        HttpResp httpResp = new HttpResp();
        httpResp.setResultCode(resultCode);
        httpResp.setTime(time);
        httpResp.setResults(results);
        return httpResp;
    }
}
