最近在搞生成包的问题,发现Mybatis plus不需要一张一张表的配置耶,所以就有了下文啦哈哈哈~
主要步骤:
1.新建基于SpringBoot的Maven项目,引入相关依赖
2.参考官方文档配置生成包的信息,编写生成generated包的主要类
3.新建模板信息(如果有自己特殊的要求的话,没有使用默认的即可)
4.将生成包打包测试 然后就可以开始使用啦~
整体项目目录结构如下(红色标记的文件为手动新增的内容):
1.新建基于SpringBoot 的 Maven项目,pom.xml如下(我这里用的mysql8.x的,可根据实际情况更改数据库驱动包哈)
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.5.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.imodule.product</groupId> <artifactId>product</artifactId> <version>0.0.1-SNAPSHOT</version> <name>product</name> <description>Demo project for Spring Boot</description> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <imodule-nexus.version>0.0.1-SNAPSHOT</imodule-nexus.version> <quartz.version>2.3.0</quartz.version> <org.slf4j-version>1.6.4</org.slf4j-version> </properties> <dependencies> <!-- spring-boot --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!--mybatis-plus自动的维护了mybatis以及mybatis-spring的依赖, 在springboot中这三者不能同时的出现,避免版本的冲突,表示:跳进过这个坑--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.0.1</version> </dependency> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.17</version> </dependency> <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity-engine-core</artifactId> <version>2.2</version> </dependency> <!-- https://mvnrepository.com/artifact/org.projectlombok/lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.8</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
2.主要配置类 CodeGenerator.java
整个生成过程中 最值得讲的就是此类了,这里我连的TiDB数据库(类似与MySQL,直接用mysql的驱动即可)
细节一:策略配置 StrategyConfig 指定数据库中哪些表需要生成Dao
String[] tablename = {"PRD_BASE","PRD_PROPERTY"}; //多张表用数组表示
strategy.setInclude(tablename);// 包含那些表,excude排除哪些表 include与excude只能设置一个(如果不添加此项配置 默认生成数据库中所有的表对应的Dao)
细节二:由于我们是用的TiDB数据库,这不是我们原来的业务数据库,所以需要从其它库传输数据到TiDB,子啊通过DataPipeline传输的时候,发现DataPipeline有个自动的功能,当它发现同步的表没有主键的时候会自动建立列 _id 作为这张表的主键,同步到TiDB指定库中,这就给我们带来了难题, _id 字段在通过mybatis plus generator生成后,属性名为 id ,去掉了前缀 _ ,当我们执行查询的时候就会找不到 id字段,手动注释掉这个 id字段后,数据又正常啦。所以我们就更改了模板文件新增了 #if判断,就是在字段迭代的时候先判断当前字段是不是 _id,如果是就不做任何操作,也就是不将此属性添加到对象总,如果不是就正常执行。
#if(${field.name.equals("_id")})
语句如下:
#foreach($field in ${table.fields}) #if(${field.name.equals("_id")}) #else ...中间省略原来的模板代码信息... private ${field.propertyType} ${field.propertyName}; #end #end
细节三:模板配置 StrategyConfig的setTablePrefix方法,我原以为是可以手动添加表前缀,结果测试发现这是去掉前缀的意思。
示例:
数据库表名称为 PRD_USER
设置 StrategyConfig.setTablePrefix("PRD_");
最后生成的实体类: User ,去掉了 PRD_ 前缀 (除了实体类 Mapper Service Controller都会统一去掉 PRD_前缀)
如果不设置的话tablePrefix的话,生成的实体类为 PrdUser (Mapper Service Controller都类似)
细节四:模板配置 TemplateConfig 指定生成的结果文件模板信息 (结果文件中需要包含哪些 语法参考对应的引擎)
templateConfig.setEntity("templates/entity.java");
templateConfig.setMapper("templates/mapper.java"); templateConfig.setXml("templates/mapper.xml"); templateConfig.setService("templates/service.java"); templateConfig.setServiceImpl("templates/serviceImpl.java"); templateConfig.setController("templates/controller.java");
这里我们使用TiDB,打算用同一套数据源,里面包含多个数据库(意思就是同一个数据库服务器里面建立多个数据库,类似与DBLINK),系统需要具备跨库查询的功能,直接生成的话是无法查询其它数据库的数据库的
所以我们在模板上做了一些小改造:在表名前增加了库名(目前没有参数可以设置,所以我们就直接在entity.java.vm模版文件中更改了,文章最后会提供更改之后的Entity模板文件)
原来是: @TableName("${table.name}")
更改后: @TableName("prd_demo.${table.name}") //在这里把库名固定了 (如果有多个库需要分别生成,每次生成前需要先更改这个schema name 数据库名称)

3. 这里用的是 VM模板,模板文件分别如下(解压官方mybatis-plus-generator-3.0.5.jar,在mybatis-plus-generator-3.0.5\templates目录下 获取的)
entity.java.vm(默认的)
package ${package.Entity}; #foreach($pkg in ${table.importPackages}) import ${pkg}; #end #if(${swagger2}) import io.swagger.annotations.ApiModel; import io.swagger.annotations.ApiModelProperty; #end #if(${entityLombokModel}) import lombok.Data; import lombok.EqualsAndHashCode; import lombok.experimental.Accessors; #end /** * <p> * $!{table.comment} * </p> * * @author ${author} * @since ${date} */ #if(${entityLombokModel}) @Data #if(${superEntityClass}) @EqualsAndHashCode(callSuper = true) #else @EqualsAndHashCode(callSuper = false) #end @Accessors(chain = true) #end #if(${table.convert}) @TableName("${table.name}") #end #if(${swagger2}) @ApiModel(value="${entity}对象", description="$!{table.comment}") #end #if(${superEntityClass}) public class ${entity} extends ${superEntityClass}#if(${activeRecord})<${entity}>#end { #elseif(${activeRecord}) public class ${entity} extends Model<${entity}> { #else public class ${entity} implements Serializable { #end private static final long serialVersionUID = 1L; ## ---------- BEGIN 字段循环遍历 ---------- #foreach($field in ${table.fields}) #if(${field.keyFlag}) #set($keyPropertyName=${field.propertyName}) #end #if("$!field.comment" != "") #if(${swagger2}) @ApiModelProperty(value = "${field.comment}") #else /** * ${field.comment} */ #end #end #if(${field.keyFlag}) ## 主键 #if(${field.keyIdentityFlag}) @TableId(value = "${field.name}", type = IdType.AUTO) #elseif(!$null.isNull(${idType}) && "$!idType" != "") @TableId(value = "${field.name}", type = IdType.${idType}) #elseif(${field.convert}) @TableId("${field.name}") #end ## 普通字段 #elseif(${field.fill}) ## ----- 存在字段填充设置 ----- #if(${field.convert}) @TableField(value = "${field.name}", fill = FieldFill.${field.fill}) #else @TableField(fill = FieldFill.${field.fill}) #end #elseif(${field.convert}) @TableField("${field.name}") #end ## 乐观锁注解 #if(${versionFieldName}==${field.name}) @Version #end ## 逻辑删除注解 #if(${logicDeleteFieldName}==${field.name}) @TableLogic #end private ${field.propertyType} ${field.propertyName}; #end ## ---------- END 字段循环遍历 ---------- #if(!${entityLombokModel}) #foreach($field in ${table.fields}) #if(${field.propertyType.equals("boolean")}) #set($getprefix="is") #else #set($getprefix="get") #end public ${field.propertyType} ${getprefix}${field.capitalName}() { return ${field.propertyName}; } #if(${entityBuilderModel}) public ${entity} set${field.capitalName}(${field.propertyType} ${field.propertyName}) { #else public void set${field.capitalName}(${field.propertyType} ${field.propertyName}) { #end this.${field.propertyName} = ${field.propertyName}; #if(${entityBuilderModel}) return this; #end } #end #end #if(${entityColumnConstant}) #foreach($field in ${table.fields}) public static final String ${field.name.toUpperCase()} = "${field.name}"; #end #end #if(${activeRecord}) @Override protected Serializable pkVal() { #if(${keyPropertyName}) return this.${keyPropertyName}; #else return null; #end } #end #if(!${entityLombokModel}) @Override public String toString() { return "${entity}{" + #foreach($field in ${table.fields}) #if($!{foreach.index}==0) "${field.propertyName}=" + ${field.propertyName} + #else ", ${field.propertyName}=" + ${field.propertyName} + #end #end "}"; } #end }
mapper.xml.vm(默认的)
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="${package.Mapper}.${table.mapperName}"> #if(${enableCache}) <!-- 开启二级缓存 --> <cache type="org.mybatis.caches.ehcache.LoggingEhcache"/> #end #if(${baseResultMap}) <!-- 通用查询映射结果 --> <resultMap id="BaseResultMap" type="${package.Entity}.${entity}"> #foreach($field in ${table.fields}) #if(${field.keyFlag})##生成主键排在第一位 <id column="${field.name}" property="${field.propertyName}" /> #end #end #foreach($field in ${table.commonFields})##生成公共字段 <result column="${field.name}" property="${field.propertyName}" /> #end #foreach($field in ${table.fields}) #if(!${field.keyFlag})##生成普通字段 <result column="${field.name}" property="${field.propertyName}" /> #end #end </resultMap> #end #if(${baseColumnList}) <!-- 通用查询结果列 --> <sql id="Base_Column_List"> #foreach($field in ${table.commonFields}) ${field.name}, #end ${table.fieldNames} </sql> #end </mapper>
mapper.java.vm(默认的)
package ${package.Mapper}; import ${package.Entity}.${entity}; import ${superMapperClassPackage}; import org.apache.ibatis.annotations.Mapper; /** * <p> * $!{table.comment} Mapper 接口 * </p> * * @author ${author} * @since ${date} */ #if(${kotlin}) interface ${table.mapperName} : ${superMapperClass}<${entity}> #else @Mapper public interface ${table.mapperName} extends ${superMapperClass}<${entity}> { } #end
service.java.vm(默认的)
package ${package.Service}; import ${package.Entity}.${entity}; import ${superServiceClassPackage}; /** * <p> * $!{table.comment} 服务类 * </p> * * @author ${author} * @since ${date} */ #if(${kotlin}) interface ${table.serviceName} : ${superServiceClass}<${entity}> #else public interface ${table.serviceName} extends ${superServiceClass}<${entity}> { } #end
seviceimpl.java.vm(默认的)
package ${package.ServiceImpl}; import ${package.Entity}.${entity}; import ${package.Mapper}.${table.mapperName}; import ${package.Service}.${table.serviceName}; import ${superServiceImplClassPackage}; import org.springframework.stereotype.Service; /** * <p> * $!{table.comment} 服务实现类 * </p> * * @author ${author} * @since ${date} */ @Service #if(${kotlin}) open class ${table.serviceImplName} : ${superServiceImplClass}<${table.mapperName}, ${entity}>(), ${table.serviceName} { } #else public class ${table.serviceImplName} extends ${superServiceImplClass}<${table.mapperName}, ${entity}> implements ${table.serviceName} { } #end
controller.java.vm(默认的)
package ${package.Controller}; import org.springframework.web.bind.annotation.RequestMapping; #if(${restControllerStyle}) import org.springframework.web.bind.annotation.RestController; #else import org.springframework.stereotype.Controller; #end #if(${superControllerClassPackage}) import ${superControllerClassPackage}; #end /** * <p> * $!{table.comment} 前端控制器 * </p> * * @author ${author} * @since ${date} */ #if(${restControllerStyle}) @RestController #else @Controller #end @RequestMapping("#if(${package.ModuleName})/${package.ModuleName}#end/#if(${controllerMappingHyphenStyle})${controllerMappingHyphen}#else${table.entityPath}#end") #if(${kotlin}) class ${table.controllerName}#if(${superControllerClass}) : ${superControllerClass}()#end #else #if(${superControllerClass}) public class ${table.controllerName} extends ${superControllerClass} { #else public class ${table.controllerName} { #end } #end
4.主类设计 ProductApplication.java
package com.imodule.product; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class ProductApplication { /** * springboot 项目主启动类 * @param args main 函数入参 */ public static void main(String[] args) { SpringApplication.run(ProductApplication.class, args); } }
执行步骤: 直接执行 CodeGenerator.java的main方法就可以了啦
执行结果: (红色框框标记的文件均为自动生成的)
5.做个测试吧,我们可以就在这个项目里面添加数据源配置信息 写测试类开始测试啦
添加数据源配置:
测试类编写:PrdBaseMapperTest.java
package com.imodule.product.mapper; import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper; import com.imodule.product.product.entity.PrdBase; import com.imodule.product.product.mapper.PrdBaseMapper; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.ContextConfiguration; import java.util.Arrays; import java.util.List; //@RunWith(SpringRunner.class) @ContextConfiguration @SpringBootTest class PrdBaseMapperTest { @Autowired private PrdBaseMapper prdBaseMapper; @Test public void testPrdBaseMapper(){ QueryWrapper queryWrapper = new QueryWrapper(); queryWrapper.eq("columnname","columnvalue");//这里写对应的列名与列值即可 List<PrdBase> prdbase = prdBaseMapper.selectList(queryWrapper); System.out.println("testPrdBaseMapper result:"+prdbase); } }
测试结果 欧克啦啦啦啦~
完整的生成流程就如上所述啦~
最后提供一下更改之后的entity模板文件(基于VM)
