Preface

Compared with the previous springmvc frame , Use springboot Development reduces the work of a large number of configuration files , It can greatly improve the efficiency of development . Use springboot If there is a new interface or method in development, the basic steps are as follows ：

1、 Corresponding data of new object entity;

2、 newly added controller;

3、 newly added dao;

4、 newly added service And corresponding impl class .

Add these things repeatedly every time , The work is not difficult , But it's boring , It's also a waste of time . Isn't it delicious to touch fish in this time ？

Recommend two today, which can greatly improve work efficiency （ loaf on a job ） The artifact of ： Automatic code generator , Some of the code really doesn't have to be written ！

One 、EasyCode

The first recommendation is idea Built-in plug-ins ---->Easy Code.EasyCode Is based on IntelliJ IDEA Developed code generation plug-ins , Support to customize any template （Java,html,js,xml）. Any database related code can be generated through custom templates . Support database type and java Type mapping configuration . Support the generation of multiple tables at the same time . Each table has independent configuration information . Completely personalized definition , The rules are set by you . Usually used to generate Entity、Dao、Service、Controller. If you have strong hands-on ability, it can also be used to generate HTML、JS、PHP Etc . In theory, any code related to data can be generated .

Easy Code Is based on Database Tool Development , all Database Tool All supported databases are supported . Common databases are basically supported .

The installation steps are as follows ： To iead Of plugins Plug in market , Search for downloads easy code that will do

After installation, you can customize the configuration through the following configuration , The default is usually used ：

Then if you need to generate specific code , It needs to be used in conjunction with Database Tool, Many database types are supported here , the mysql：

After the above configuration is completed, select the table that needs to generate relevant codes , choice easycode–>generate code that will do

In this way, all the required code is generated successfully ：

That's how to use idea Of easycode Use of code generation plug-ins ！

Two 、CodeGenerator

This is a mybatis-plus Code generator for , Directly copy the following code , Just put it in a separate folder in the project , Each time according to specific needs , Modify some relevant parameter values , The specific code and relevant comments are explained as follows ：

package com.jiangxia.demo;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;
import com.baomidou.mybatisplus.generator.config.PackageConfig;
import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.DateType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import org.junit.Test;

/**
 * @author:jiangxia
 * @since 2022/04/25
 */
public class CodeGenerator {
    @Test
    public void run() {
        // 1、 Create a code generator 
        AutoGenerator mpg = new AutoGenerator();
        // 2、 Global configuration 
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setAuthor("testjava");
        gc.setOpen(false); // Whether to open Explorer after generation 
        gc.setFileOverride(false); // Whether the file is overwritten during regeneration 
        gc.setServiceName("%sService");  // Get rid of Service The initial of the interface I
        gc.setIdType(IdType.ID_WORKER); // The primary key strategy 
        gc.setDateType(DateType.ONLY_DATE);// Defines the date type in the generated entity class 
        gc.setSwagger2(true);// Turn on Swagger2 Pattern 
        mpg.setGlobalConfig(gc);
        // 3、 Data source configuration 
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/test");
        dsc.setDriverName("om.mysql.cj.jdbc.Driver");
        dsc.setUsername("jiang");
        dsc.setPassword("jiang");
        dsc.setDbType(DbType.MYSQL);
        mpg.setDataSource(dsc);
        // 4、 Package configuration 
        PackageConfig pc = new PackageConfig();
        pc.setModuleName("codedemo"); // Module name 
        pc.setParent("com.jiangxia.demo");// Which bag 
        pc.setController("controller");//comtroller
        pc.setEntity("entity");//entity
        pc.setService("service");//service
        pc.setMapper("mapper");//mapper
        mpg.setPackageInfo(pc);
        // 5、 Policy configuration 
        StrategyConfig strategy = new StrategyConfig();
        strategy.setInclude("user");
        strategy.setNaming(NamingStrategy.underline_to_camel);// Naming strategy of database table mapping to entity 
        strategy.setTablePrefix(pc.getModuleName() + "_"); // Remove the table prefix when generating entities 

        strategy.setColumnNaming(NamingStrategy.underline_to_camel);// Database table fields are mapped to entity naming policies 
        strategy.setEntityLombokModel(true); // lombok  Model  @Accessors(chain = true) setter Chain operation 

        strategy.setRestControllerStyle(true); //restful api Style controller 
        strategy.setControllerMappingHyphenStyle(true); //url Middle hump to hyphen 
        mpg.setStrategy(strategy);
        // 6、 perform 
        mpg.execute();
    }
}

The setting of the above code only needs to modify the specific database and corresponding table each time . After executing the above code, the corresponding controller、entity Etc , Reduce a lot of creation work .

summary

The above are two automatic code generation tools , You can choose to use... According to your actual situation and needs , This can greatly reduce the unnecessary workload every time , Improve work efficiency , Finish the work early , Get off work early ！

If you find it useful , Just like it and forward it to more friends ！

If you have any other useful automatic code generation tools , Welcome to , recommend ！
