使用人人开源【renren-generator】快速构建项目

1.从gitee拉取renren-generator

地址：renren-generator: 人人开源项目的代码生成器，可在线生成entity、xml、dao、service、vue、sql代码，减少70%以上的开发任务 (gitee.com)https://gitee.com/renrenio/renren-generator 将项目克隆到本地。

2.修改配置

1.在application.yml修改配置如下

server:
  port: 81

# mysql
spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    #MySQL配置
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://xxx.xxx.xxx.x:3306/gulimall_ums?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
    username: root
    password: root
    #oracle配置
    #    driverClassName: oracle.jdbc.OracleDriver
    #    url: jdbc:oracle:thin:@47.100.206.162:1521:xe
    #    username: renren
    #    password: 123456
    #SQLServer配置
    #    driverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriver
    #    url: jdbc:sqlserver://192.168.10.10:1433;DatabaseName=renren_fast
    #    username: sa
    #    password: 123456
    #PostgreSQL配置
  #    driverClassName: org.postgresql.Driver
  #    url: jdbc:postgresql://192.168.10.10:5432/renren_fast
  #    username: postgres
  #    password: 123456



  jackson:
    time-zone: GMT+8
    date-format: yyyy-MM-dd HH:mm:ss
  resources:
    static-locations: classpath:/static/,classpath:/views/

#mongodb:
#  host: localhost
#  port: 27017
#  auth: false #是否使用密码验证
#  username: tincery
#  password: renren
#  source: 123456
#  database: test

mybatis-plus:
  mapperLocations: classpath:mapper/**/*.xml


pagehelper:
  reasonable: true
  supportMethodsArguments: true
  params: count=countSql


#指定数据库，可选值有【mysql、oracle、sqlserver、postgresql、mongodb】
renren:
  database: mysql

将数据源配置设置成自己的数据库配置

2.修改generator.properties配置

#\u4EE3\u7801\u751F\u6210\u5668\uFF0C\u914D\u7F6E\u4FE1\u606F

mainPath=com.test
#\u5305\u540D
package=com.test.gulimall
moduleName=member
#\u4F5C\u8005
author=author
#Email
email=author@gmail.com
#\u8868\u524D\u7F00(\u7C7B\u540D\u4E0D\u4F1A\u5305\u542B\u8868\u524D\u7F00)
tablePrefix=ums_

#\u7C7B\u578B\u8F6C\u6362\uFF0C\u914D\u7F6E\u4FE1\u606F
tinyint=Integer
smallint=Integer
mediumint=Integer
int=Integer
integer=Integer
bigint=Long
float=Float
double=Double
decimal=BigDecimal
bit=Boolean

char=String
varchar=String
tinytext=String
text=String
mediumtext=String
longtext=String


date=Date
datetime=Date
timestamp=Date

NUMBER=Integer
INT=Integer
INTEGER=Integer
BINARY_INTEGER=Integer
LONG=String
FLOAT=Float
BINARY_FLOAT=Float
DOUBLE=Double
BINARY_DOUBLE=Double
DECIMAL=BigDecimal
CHAR=String
VARCHAR=String
VARCHAR2=String
NVARCHAR=String
NVARCHAR2=String
CLOB=String
BLOB=String
DATE=Date
DATETIME=Date
TIMESTAMP=Date
TIMESTAMP(6)=Date

int8=Long
int4=Integer
int2=Integer
numeric=BigDecimal

nvarchar=String

设置要生成的包路径、包名、作者、邮箱、数据库表前缀即可

3.在模板中去掉对我们无用的代码

resources/template目录下即为我们要生成的代码模板

比如：我们去除权限管理，只需要注释或删除相关的代码即可

package ${package}.${moduleName}.controller;

import java.util.Arrays;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import ${package}.${moduleName}.entity.${className}Entity;
import ${package}.${moduleName}.service.${className}Service;
import ${mainPath}.common.utils.PageUtils;
import ${mainPath}.common.utils.R;



/**
 * ${comments}
 *
 * @author ${author}
 * @email ${email}
 * @date ${datetime}
 */
@RestController
@RequestMapping("${moduleName}/${pathName}")
public class ${className}Controller {
    @Autowired
    private ${className}Service ${classname}Service;

    /**
     * 列表
     */
    @RequestMapping("/list")
##    @RequiresPermissions("${moduleName}:${pathName}:list")
    public R list(@RequestParam Map<String, Object> params){
        PageUtils page = ${classname}Service.queryPage(params);

        return R.ok().put("page", page);
    }
    resources/template/Controller.java.vm

    /**
     * 信息
     */
    @RequestMapping("/info/{${pk.attrname}}")
##    @RequiresPermissions("${moduleName}:${pathName}:info")
    public R info(@PathVariable("${pk.attrname}") ${pk.attrType} ${pk.attrname}){
		${className}Entity ${classname} = ${classname}Service.getById(${pk.attrname});

        return R.ok().put("${classname}", ${classname});
    }

    /**
     * 保存
     */
    @RequestMapping("/save")
##    @RequiresPermissions("${moduleName}:${pathName}:save")
    public R save(@RequestBody ${className}Entity ${classname}){
		${classname}Service.save(${classname});

        return R.ok();
    }

    /**
     * 修改
     */
    @RequestMapping("/update")
##    @RequiresPermissions("${moduleName}:${pathName}:update")
    public R update(@RequestBody ${className}Entity ${classname}){
		${classname}Service.updateById(${classname});

        return R.ok();
    }

    /**
     * 删除
     */
    @RequestMapping("/delete")
##    @RequiresPermissions("${moduleName}:${pathName}:delete")
    public R delete(@RequestBody ${pk.attrType}[] ${pk.attrname}s){
		${classname}Service.removeByIds(Arrays.asList(${pk.attrname}s));

        return R.ok();
    }

}

4.Run一把启动类
