mybais-plus integration springboot, automatic code generation.

The first step: the leader packet: mybatis-plus-generator packages and packages freemarker

<dependencies>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.3.0</version>
        </dependency>
        <dependency>
            <groupId>org.freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>2.3.29</version>
        </dependency>
    </dependencies>

Step Two: class code generation:

public class generate {
        /**
         * <p>
         * 读取控制台内容
         * </p>
         */
        public static String scanner(String tip) {
            Scanner scanner = new Scanner(System.in);
            StringBuilder help = new StringBuilder();
            help.append("请输入" + tip + "：");
            System.out.println(help.toString());
            if (scanner.hasNext()) {
                String ipt = scanner.next();
                if (StringUtils.isNotEmpty(ipt)) {
                    return IPT; 
                } 
            } 
            the throw  new new MybatisPlusException ( "Please enter the correct" Tip + + "!" ); 
        } 

        public  static  void main (String [] args) {
             // code generator 
            AutoGenerator MPG = new new AutoGenerator (); 

            // global 
            globalconfig GC = new new globalconfig (); 
            String ProjectPath = the System.getProperty ( "user.dir" ); 
　　　　　　　　// generates code in which a path
             gc.setOutputDir (ProjectPath + "/ bootstudy / the src / main / Java") ;
　　　　　　　　// created
            gc.setAuthor ( "Yang" ); 
            gc.setOpen ( to false );
             // gc.setSwagger2 (to true); entity attributes Swagger2 annotation 
            mpg.setGlobalConfig (GC); 

            // data source configuration 
            DataSourceConfig DSC = new new DataSourceConfig (); 
　　　　　　　　/ / set database information
            dsc.setUrl ( "jdbc: MySQL: // localhost:? 3306 / = to true useUnicode the Boot & useSSL = false & characterEncoding = utf8 & serverTimezone = Asia / on Shanghai"); 
            // dsc.setSchemaName ( "public"); 
            dsc.setDriverName ( "com.mysql.cj.jdbc.Driver" ); 
            dsc.setUsername ( "root" );
            dsc.setPassword("123456" ); 
            mpg.setDataSource (DSC); 

            // package configuration 
            PackageConfig PC = new new PackageConfig (); 
　　　　　　　　// Set the module name
            pc.setModuleName (Scanner ( "module name")); 
            pc.setParent ( "com.springboot .modules "); 
            pc.setEntity (" Model " ); 
            mpg.setPackageInfo (PC); 

            // custom configuration 
            InjectionConfig CFG = new new InjectionConfig () { 
                @Override 
                public  void initMap () {
                     // to do Nothing 
                } 
            }; 

            // if the template engine is FreeMarker 
           String the templatePath = "/ templates / mapper.xml.ftl ";
             // If the template engine is Velocity
             // String the templatePath = "/templates/mapper.xml.vm"; 

            // custom output configurations 
            List < FileOutConfig> = focList new new the ArrayList <> ();
             // custom configuration may be preferentially output 
            focList.add ( new new FileOutConfig (the templatePath) { 
                @Override 
                public String the outputFile (the TableInfo TableInfo) {
                     // customize the output file name, if you Entity set up before the suffix name xml attention here will change !! ensuing 
                    return ProjectPath + "/ bootstudy / src / main / Resources / Mapper /" +pc.getModuleName ()
                             + "/" + tableInfo.getEntityName () + "Mapper" + StringPool.DOT_XML; 
                }
            }); 
        / * 
        Cfg.setFileCreate (new new IFileCreate () { 
            @Override 
            public boolean isCreate (ConfigBuilder configBuilder, FileType fileType, String filePath) { 
                // determine whether you need a custom folder created 
                checkDir ( "call the default method to create the directory" ); 
                return to false; 
            } 
        }); 
        * / 
            cfg.setFileOutConfigList (focList); 
            mpg.setCfg (CFG); 

            // configuration template 
            templateConfig templateConfig = new new templateConfig (); 

            // configure custom output templates
             // specify a custom template path, be careful not to bring .ftl / .vm, will be automatically recognized by the template engine used
             //templateConfig.setEntity ( "Templates / entity2.java");
             // templateConfig.setService ();
             // templateConfig.setController (); 

            templateConfig.setXml ( null ); 
            mpg.setTemplate (templateConfig); 

            // policy configuration 
            StrategyConfig strategy = new new StrategyConfig (); 
            strategy.setNaming (NamingStrategy.underline_to_camel); 
            strategy.setColumnNaming (NamingStrategy.underline_to_camel); 
          // strategy.setSuperEntityClass ( "your own parent entity, no do not set!"); 
            strategy.setEntityLombokModel ( to true ); 
            strategy.setRestControllerStyle ( to true );
             // common parent class
            // strategy.setSuperControllerClass ( "you yourself the parent controller, no do not set! ");
             // write to the parent class public fields 
            strategy.setSuperEntityColumns (" the above mentioned id " ); 
            strategy.setInclude (Scanner ( " table, multiple comma split ") .split ( "," )); 
            strategy.setControllerMappingHyphenStyle ( to true ); 
            strategy.setTablePrefix (pc.getModuleName () + "_" ); 
            mpg.setStrategy ( Strategy); 
            mpg.setTemplateEngine ( new new FreemarkerTemplateEngine ()); 
            mpg.execute (); 
        } 
}

The main point is to note that the points marked red: When setting up a database error when I did not add that when & serverTimezone = Asia / Shanghai, set the mysql driver name, not add cj warning will be reported out of date, but does not affect

The third step is to configure freemarker:
