springboot整合mybatisplus代码生成器

前提准备

准备一个表，表字段自定义

1.准备pom依赖

  
 
            org.springframework.boot
            spring-boot-starter-web
        
  
        
            mysql
            mysql-connector-java
            runtime
        
          
        
            org.projectlombok
            lombok
            true
        
  
        
            org.springframework.boot
            spring-boot-starter-test
            test
        

        
            com.baomidou
            mybatis-plus-boot-starter
            3.5.1
        
        
            com.baomidou
            mybatis-plus-generator
            3.5.2
        
        
        
        org.apache.velocity
        velocity-engine-core
        2.3
         
        
        
            io.springfox
            springfox-swagger2
            2.7.0
        
        
        
            com.github.xiaoymin
            swagger-bootstrap-ui
            1.9.6
        

2.配置yml

server:
  port: 8088


spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?
useUnicode=true&characterEncoding=UTF-8&
serverTimezone=Asia/Shanghai
    username: root
    password: 123
    hikari:
      pool-name: DateHikariCP
      minimum-idle: 5
      idle-timeout: 180000
      maximum-pool-size: 10
      auto-commit: true
      max-lifetime: 1800000
      connection-timeout: 30000
      connection-init-sql: SELECT 1
#Mybatis-plus 配置
mybatis-plus:
  mapper-locations: classpath*:/xml/*Mapper.xml
  type-aliases-package: springx.pojo
  configuration:
    map-underscore-to-camel-case: false
##打印 sql
logging:
  level:
    yeb.service.mapper: debug

3.在test目录下新建一个gemerator.java文件

  public static void main(String[] args) {
        //配置数据库路径
        String projectPath = System.getProperty("user.dir");
        DataSourceConfig.Builder dataSourceConfigBuilder = new DataSourceConfig.Builder(
"jdbc:mysql://localhost:3306/springsucurity?useUnicode=true&
characterEncoding=UTF-8&serverTimezone=Asia/Shanghai", 
"root",
                "123")
                .dbQuery(new MySqlQuery())
                .typeConvert(new MySqlTypeConvert())
                .keyWordsHandler(new MySqlKeyWordsHandler());


        FastAutoGenerator fastAutoGenerator = FastAutoGenerator.create(dataSourceConfigBuilder);
        //全局配置
        fastAutoGenerator.globalConfig(
                globalConfigBuilder -> globalConfigBuilder
                        //覆盖生成文件
                        .fileOverride()
                        .disableOpenDir()
                        //指定输出目录
                        .outputDir(projectPath + "/src/main/java")
                        //设置作者
                        .author("夏JCC")
                        //设置日期
                        .commentDate("yyyy-MM-dd HH:mm:ss")
                        //使用新的日期格式.
                        .dateType(DateType.TIME_PACK)
                        //开启swagger注解
                        .enableSwagger()
        );
        //生成表名配置
        fastAutoGenerator.strategyConfig(
                strategyConfigBuilder -> strategyConfigBuilder
                        //开启大写命名
                        .enableCapitalMode()
                        //开启跳过视图
                        .enableSkipView()
                        //禁用sql过滤
                        .disableSqlFilter()
                        //添加需要生成的表名
                        .addInclude("t_admin","t_role")
                        //忽略表前缀
                        .addTablePrefix("t_")
        );
        //包的配置
        fastAutoGenerator.packageConfig(
                packageConfigBuilder -> packageConfigBuilder
                         //设置父包名  下面的parent内容要改成自己的父包名，
                        .parent("mybatisplus")
                        //以下是配置各个包名
                        .entity("pojo")
                        .mapper("mapper")
                        //根据需要来构筑xml
                        .xml("mapper.xml")
                        .service("service")
                        .serviceImpl("service.impl")
                        .controller("controller")
        );
     //实体类的策略配置
        fastAutoGenerator.strategyConfig(
                strategyConfigBuilder ->
                        strategyConfigBuilder.entityBuilder()
                           
                         //开启实体类字段注解
                          .enableTableFieldAnnotation()
                           //数据库表和字段映射的时候，下划线转驼峰
                           .naming(NamingStrategy.underline_to_camel)
                        .columnNaming(NamingStrategy.underline_to_camel)
                             //全局的主键类型是ASSIGN_ID
                             .idType(IdType.AUTO)
                             //开启lombok
                             .enableLombok()
                             //逻辑删除的字段名
                           .logicDeleteColumnName("deleted")
                            .logicDeletePropertyName("deleted")
                             //自动填充配置，创建时间，更新时间
                .addTableFills(new Column("create_time",FieldFill.INSERT))
                           .addTableFills(new Property("updateTime",FieldFill.INSERT_UPDATE))
                                //开启乐观锁
                                .versionColumnName("version")
                                .disableSerialVersionUID()
        );
        //开启Controller策略配置
        fastAutoGenerator
                .strategyConfig(strategyConfigBuilder ->
                        strategyConfigBuilder
                                //开启@RestController控制器
                                .controllerBuilder()
                                //开启请求rest风格
                                .enableRestStyle()
                                .enableHyphenStyle()
                );
        //service策略配置
        fastAutoGenerator.strategyConfig(
                strategyConfigBuilder -> strategyConfigBuilder
                        .serviceBuilder()
                        //格式化文件名称，没什么可注意的，开启即可
                        .formatServiceFileName("%sService")
                        .formatServiceImplFileName("%sServiceImpl"));
         //注意Mapper策略配置
         //.enableBaseColumnList()
         //.superClass(BaseMapper.class)
         //.enableMapperAnnotation()
        fastAutoGenerator.strategyConfig(
                strategyConfigBuilder ->
                        strategyConfigBuilder.mapperBuilder()
                                //开启resultMap，很重要
                                .enableBaseResultMap()
                                .enableBaseColumnList()
                                .superClass(BaseMapper.class)
                                .enableMapperAnnotation()
                                //生成Mapper包名
                                .formatMapperFileName("%sMapper")
                                .formatXmlFileName("%sMapper"));
       //生成代码
         fastAutoGenerator.execute();

效果如下

那么接下来我推荐一个插件MybatisX

 4.MybatisX功能一

点击小鸟即可实现xml和对应mapper的互相跳转

 5.MybatisX功能二

 

  6.MybatisX功能三

前提，idea如何配置database数据库我就不在这里说明了，可自行百度。

     

 

 

 效果如下，新生成了对应的包

以上就是springboot整合mybatisPlus的内容。
