springboot + mybatisplus integrate and use reverse engineering

First introduced maven dependence: It is dependent upon the integration of mybatisplus, reverse engineering time needed to introduce the

 <!--mybaitsplus   start-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>2.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.0</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.16</version>
        </dependency>
        <!--mybaitsplus   end-->

<!--        lombok   start-->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.8</version>
</dependency>
<!--        lombok   end-->

Step 2: Perform configuration file application.yml

the Spring: 
  the DataSource: 
    of the type: com.alibaba.druid.pool.DruidDataSource 
    Driver - class - name: com.mysql.jdbc.Driver 
    url: jdbc: MySQL: // ? localhost: 3306 / = dbname useUnicode to true & characterEncoding = = utf8 & allowMultiQueries to true 

    password : password 
    Druid: 
      # initial size, minimum, maximum 
      Initial -size:. 5 
      min -idle:. 5 
      for maxActive: 20 is 
      # configuration obtaining connection waiting timeout time 
      maxWait: 60000 
      # intervals the frequency of such detection, the detection needs to close idle connections milliseconds 
      timeBetweenEvictionRunsMillis: 60000 
      # configure a minimum survival time connection pool, in milliseconds
      minEvictableIdleTimeMillis: 300000 
      validationQuery: the SELECT 1 
      testWhileIdle: to true 
      testOnBorrow: false 
      testOnReturn: false 
      # open PSCache, and specify the size of each connection PSCache 
      poolPreparedStatements: to true 
      maxPoolPreparedStatementPerConnectionSize: 20 
      # configure the monitoring statistics intercepted filters, after removing the monitoring interface sql not statistics , 'Wall' firewalls 
      Filters: STAT, Wall 
      # mergeSql opened by connectProperties function attributes; slow SQL record 
      ConnectionProperties: druid.stat.mergeSql \ = to true ; druid.stat.slowSqlMillis \ = 5000 
      # configure DruidStatFilter
      Web -stat- 
        Enabled: to true 
        # password
        url -pattern: "/ *" 
        Exclusions: . "..... * .js, * GIF, JPG *, * BMP, PNG *, * CSS, ico *, / Druid / *" 
      # Configure DruidStatViewServlet 
      STAT the -view - 
        url -pattern: "/ Druid / *" 
        # IP whitelist (not configured or is empty, then allow all access) 
        the allow: 127.0.0.1,192.168.163.1 
        # IP blacklist (when there is a common, deny priority to allow) 
        deny: 192.168.1.73 
        # disable HTML page on the "Reset All" function of 
        the RESET -enable: false 
        # login name 
        the Login - username: ADMIN 
        the Login -password: 123456 
the mybatis - PLUS: 
  Mapper-locations: classpath:/com/example/demo/mapper/*/*.xml
  typeAliasesPackage: com.example.demo.entity
  global-config:
    id-type: 2
    field-strategy: 2
    db-column-underline: true
    refresh-mapper: true
  configuration:
    map-underscore-to-camel-case: true
    cache-enabled: false
server:
  port: 8082

The third step: configuration classes and class tab plug-in configuration of the generated code:

package com.qingmu.springboot.common.Generator;

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.DbType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

public class CodeGenerator {

    public static final String DB_URL = "jdbc:mysql://192.168.2.48:3306/order_system?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true";
    public static final String USER_NAME = "root";
    public static final String PASSWORD = "root";
    public static final String DRIVER = "com.mysql.jdbc.Driver";
    public static final String AUTHOR = "qingmu";
    //生成的文件输出到哪个目录
    public static final String OUTPUT_FILE = "D:\\nums-project\\springboot\\src\\main\\java"
    public static final String PACKAGE = "com.qingmu.springboot.common";
    //TODO 更多配置请参考http://mp.baomidou.com/#/generate-code

    public void generateByTables(boolean
        GlobalConfig config = new
        DataSourceConfig dataSourceConfig = new
        dataSourceConfig.setDbType(DbType.MYSQL)
                .setUrl(DB_URL)
                .setUsername(USER_NAME)
                .setPassword(PASSWORD)
                .setDriverName(DRIVER);
        StrategyConfig strategyConfig = new
        strategyConfig 
                .setCapitalMode ( to true ) 
                .setEntityLombokModel ( false ) 
                .setDbColumnUnderline ( to true 
                .setNaming (NamingStrategy.underline_to_camel) 
                .setInclude (TableNames); // modify replace the table name you need more than one table name to an array 
        config.setActiveRecord ( false 
                .setAuthor (the AUTHOR) 
                .setOutputDir (OUTPUT_FILE) 
                .setFileOverride ( to true );
         IF (! 
            config.setServiceName ( "% Sservice" ); 
        } 
        new new AutoGenerator().setGlobalConfig(config)
                .setDataSource(dataSourceConfig)
                .setStrategy(strategyConfig)
                .setPackageInfo(
                        new PackageConfig()
                                .setParent(PACKAGE)
                                .setController("controller")
                                .setEntity("entity")
                ).execute();
    }
}

package com.example.demo.config;
import com.baomidou.mybatisplus.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import
@Configuration
@MapperScan("com.example.demo.mapper")
public class MybatisPlusConfig {
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }
}

The fourth step: a write Junit test class used to generate the code

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {
    @Test
    public void contextLoads() {
        CodeGenerator gse = new CodeGenerator();
        //要给那些表生成
        gse.generateByTables(false,"tb_user", "tb_role","tb_permission","tb_user_role","tb_role_permission");
    }
}

These are used to generate code
