springboot+mybatisplus進行整合並且使用逆向工程

首先引入maven依賴:這是整合mybatisplus時,進行逆向工程時候需要引入的依賴

 <!--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-->

第二步:進行配置application.yml文件

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/dbname?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true
    username: username
    password: password
    druid:
      # 初始化大小，最小，最大
      initial-size: 5
      min-idle: 5
      maxActive: 20
      # 配置獲取連接等待超時的時間
      maxWait: 60000
      # 配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒
      timeBetweenEvictionRunsMillis: 60000
      # 配置一個連接在池中最小生存的時間，單位是毫秒
      minEvictableIdleTimeMillis: 300000
      validationQuery: SELECT 1 FROM DUAL
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      # 打開PSCache，並且指定每個連接上PSCache的大小
      poolPreparedStatements: true
      maxPoolPreparedStatementPerConnectionSize: 20
      # 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
      filters: stat,wall
      # 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄
      connectionProperties: druid.stat.mergeSql\=true;druid.stat.slowSqlMillis\=5000
      # 配置DruidStatFilter
      web-stat-filter:
        enabled: true
        url-pattern: "/*"
        exclusions: "*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*"
      # 配置DruidStatViewServlet
      stat-view-servlet:
        url-pattern: "/druid/*"
        # IP白名單(沒有配置或者為空，則允許所有訪問)
        allow: 127.0.0.1,192.168.163.1
        # IP黑名單 (存在共同時，deny優先於allow)
        deny: 192.168.1.73
        #  禁用HTML頁面上的“Reset All”功能
        reset-enable: false
        # 登錄名
        login-username: admin
        # 登錄密碼
        login-password: 123456
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

第三步:配置生成代碼的類和分頁插件配置類:

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";
    //生成的文件輸出到哪個目錄
    public static final String OUTPUT_FILE = "D:\\nums-project\\springboot\\src\\main\\java";
    //包名，會按照com/example/demo這種形式生成類
    public static final String PACKAGE = "com.qingmu.springboot.common";
    //TODO 更多配置請參考http://mp.baomidou.com/#/generate-code

    public void generateByTables(boolean serviceNameStartWithI, String... tableNames) {
        GlobalConfig config = new GlobalConfig();
        DataSourceConfig dataSourceConfig = new DataSourceConfig();
        dataSourceConfig.setDbType(DbType.MYSQL)
                .setUrl(DB_URL)
                .setUsername(USER_NAME)
                .setPassword(PASSWORD)
                .setDriverName(DRIVER);
        StrategyConfig strategyConfig = new StrategyConfig();
        strategyConfig
                .setCapitalMode(true)
                .setEntityLombokModel(false)
                .setDbColumnUnderline(true)
                .setNaming(NamingStrategy.underline_to_camel)
                .setInclude(tableNames);//修改替換成你需要的表名，多個表名傳數組
        config.setActiveRecord(false)
                .setAuthor(AUTHOR)
                .setOutputDir(OUTPUT_FILE)
                .setFileOverride(true);
        if (!serviceNameStartWithI) {
            config.setServiceName("%sService");
        }
        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 org.springframework.context.annotation.Configuration;
@Configuration
@MapperScan("com.example.demo.mapper")
public class MybatisPlusConfig {
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }
}

第四步:寫一個Junit test類,用來生成代碼

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

以上就是用來生成的代碼
