介绍

基于gradle构建工具并支持gradle的代码生成插件,生成代码支持类型如下:

  • 数据库类型

    • mysql5.6+
    • postgresql12+
    • mariadb10+
    • h2
    • sqlite
    • mssql
    • oracle
    • db2
    • sybase
  • 支持框架及特点

    • gradle
    • maven
    • springboot
    • springmvc
    • mybatis
    • mybatis-plus
    • swagger2
    • swagger-bootstrap-ui
    • knife4j(swagger-bootstrap-ui的新版本,使用过,目前尚存在一些问题,推荐使用原版)
  • 支持语言

    • java
    • kotlin
    • groovy

生成的代码,在mybatis版本中,是默认直接生成从dao层到controller层的CRUD,mybatis-plus则按照官方代码生成方式 目前暂时推荐使用创建独立的gradle文件,并在build.gradle或build.gradle.kts中引用即可。

为什么上传到maven仓库?第一次申请被拒绝了,而且也不是很熟悉发布流程,熟悉的可以考虑发布到maven仓库中。

开启swaggerUI如下(仅试用于springboot) java开启swaggerUI文档代码

                .apiInfo(apiInfo())
                .enable(enable)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.xxx.xxx.controller"))
                .paths(PathSelectors.any())
                .build();
                //.globalOperationParameters(pars);

                .contact(Contact("author", "company website", "your email"))
                .build()
    }
}

软件架构

  1. kotlin;
  2. velocity引擎模板;
  3. gradle;

安装教程

  1. git clone;
  2. 使用gradle构建;
  3. 发布到本地maven仓库;
  4. 注意:gradle配置的maven根据实际情况来修改,我设置maven仓库如下:
// 指定上传的路径(上传到本地maven仓库)
def localMavenRepo = 'file://' + new File(System.getProperty('user.home'), '.m2/repository').absolutePath

uploadArchives {
    repositories {
        mavenDeployer {
            repository(url: localMavenRepo)
            pom.project {
                name = project.name
                packaging = 'jar'
                description = 'code generate gradle task'
            }
        }
    }
}

或者使用命令打全包

gradle jar

使用说明

在build.gradle中直接使用(推荐创建独立gradle文件并引用)
  1. 创建新的项目,引用插件gradle配置如下:
buildscript {
    repositories {
        mavenLocal()// 如果需要独立配置maven仓库地址的,使用
        /*maven {
            url uri(System.getProperty('user.home') + '/.m2/repository')//自定义插件已发布的仓库地址(本地maven仓库)
            //url uri('自定义maven仓库地址')
        }*/
        //flatDir { dirs 'libs' }
    }
    dependencies {
        //引入自定义task
        classpath group: 'cn.plugins.generator', name: 'cn-plugins-generator', version: '1.0.0'
    }
}
  1. 在工程项目中的gradle配置文件中新增一个task,代码如下:
task generateCode(type: cn.plugins.generator.task.GenerateCodeTask) {
    dbType = 'mysql' // 值为mysql或postgresql  由于mariadb为mysql的分支,所以是mariadb的,此处直接填写mysql即可
    url = 'localhost'
    port = '3306'
    database = 'manager'
    userName = 'root'
    password = 'admin123456'
    frameworkType = "mybatisplus" // mybatis或mybatisplus
    tablePrefix = 'temp' // 不要带前缀下划线进来
    tableName = 'temp_banner,temp_user,temp_user_role'// 多个表使用英文逗号隔开
    projectPath = projectDir.path
    packageName = 'com.example.gencode'
    controller = "controller"
    service = 'service'
    mapper = 'mapper'
    entity = 'entity'
    xml = 'mapper'
    languageType = 'java'// java或kotlin
    author = 'jiangyun'
    company = '测试公司'
    apiPrefix = '/api'// 默认值:/api
    enableGenerateDoc = true // 是否生成支持swaggerUI2文档
}
  1. 生成代码只需运行上述的task即可
独立gradle文件并引用的方式
  1. 在项目根目录下创建一个叫generate.gradle的文件,内容如下:
buildscript {
    repositories {
        mavenLocal()// 这块根据自定义maven地址而定,如果是发布的本地maven库而不是自定义的本地maven库,则直接这样使用即可,否则使用下面被注释的部分
        /*maven {
            url uri(System.getProperty('user.home') + '/.m2/repository')//自定义插件已发布的仓库地址
        }*/
        maven { url 'https://maven.aliyun.com/repository/public/' }// 必须有,否则会导致依赖失败而无法构建,除非本地maven仓库中包含有全部依赖
    }
    dependencies {
        //引入自定义task
        classpath group: 'cn.plugins.generator', name: 'cn-plugins-generator', version: '1.0.0'
    }
}

task generateCode(type: cn.plugins.generator.task.GenerateCodeTask) {
    dbType = 'mysql' // 值为mysql或postgresql 由于mariadb为mysql的分支,所以是mariadb的,此处直接填写mysql即可
    url = 'localhost'
    port = '3306'
    database = 'manager'
    userName = 'root'
    password = 'admin123456'
    frameworkType = "mybatisplus" // mybatis或mybatisplus
    tablePrefix = 'temp' // 不要带前缀下划线进来
    tableName = 'temp_banner,temp_user,temp_user_role'// 多个表使用英文逗号隔开
    projectPath = projectDir.path
    packageName = 'com.example.gencode'
    controller = "controller"
    service = 'service'
    mapper = 'mapper'
    entity = 'entity'
    xml = 'mapper'
    languageType = 'java'// java或kotlin
    author = 'jiangyun'
    company = '测试公司'
    apiPrefix = '/api'// 默认值:/api
    enableGenerateDoc = true // 是否生成支持swaggerUI2文档
}
  1. 在项目根目录下的build.gradle中添加如下内容:
apply from: 'generate.gradle'

引用gradle配置到主build.gradle配置文件中即可

想在springboot2.+的kotlin中怎么使用?目前spring官方默认给出的是使用kotlin编写DSL,不熟悉的人,就比较费劲了,文件也不再是以.gradle结束,而是.gradle.kts。 如下的脚本为kotlin编写DSL的使用方式,具体使用方式如下:

在工程目录下创建一个独立的叫generate.gradle.kts的文件,文件脚本内容如下:

import cn.plugins.generator.task.GenerateCodeTask

buildscript {
    repositories {
        mavenLocal()
        maven {
            setUrl("https://maven.aliyun.com/repository/public/")
        }
        dependencies {
            //引入自定义task
            classpath("cn.plugins.generator:cn-plugins-generator:1.0.0")
        }
    }
}

tasks.register<GenerateCodeTask>(name = "generateCode") {
    dbType = "mysql"// 值为mysql或postgresql 由于mariadb为mysql的分支,所以是mariadb的,此处直接填写mysql即可
    url = "localhost"
    port = "3306"
    database = "pagehelper-test"
    userName = "root"
    password = "admin1230"
    frameworkType = "mybatis" // mybatis 或 mybatisplus
    tablePrefix = "test" // 不要带前缀下划线进来
    tableName = "test_login"// 多个表使用英文逗号隔开
    projectPath = projectDir.path
    packageName = "com.example.demo"
    controller = "controller"
    service = "service"
    mapper = "mapper"
    entity = "entity"
    xml = "mapper"
    languageType = "kotlin"// java或kotlin
    author = "jy"
    company = "测试公司"
    apiPrefix = "/api"// 默认值:/api
    enableGenerateDoc = true // 是否生成支持swaggerUI2文档
}

然后在build.gradle.kts文件中引用该gradle脚本:

apply(from = "generate.gradle.kts") // 特殊就在这个地方,这是kotlin编写DSL的脚本,与groovy还是有区别的 groovy的为:apply from: 'generate.gradle'
  1. 生成代码只需运行上述的task即可 image
