2、配置 application.yml
server:
port: 8081
spring:
application:
name: product-service
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://00.00.00.00:3306/shop-product?characterEncoding=utf-8&useSSL=false&autoReconnect=true&rewriteBatchedStatements=true&nullCatalogMeansCurrent=true&allowMultiQueries=true&serverTimezone=GMT%2B8
username: root
password: root
hikari:
max-lifetime: 1800000
connection-timeout: 5000
idle-timeout: 3600000
maximum-pool-size: 12
minimum-idle: 4
connection-test-query: /**ping*/
mybatis-plus:
configuration:
#显示SQL输出
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
global-config:
db-config:
logic-delete-field: delete_flag
id-type: auto
mapper-locations: classpath:/mapper/*.xml
3、配置类 MybatisPlusConfig.class
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import lombok.extern.slf4j.Slf4j;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;
import java.util.Date;
@Slf4j
@Component
public class MybatisPlusConfig implements MetaObjectHandler {
@Override
public void insertFill(MetaObject metaObject) {
Date date = new Date();
this.setFieldValByName("createDate", date, metaObject);
this.setFieldValByName("updateDate", date, metaObject);
this.setFieldValByName("deleteFlag", false, metaObject);
}
@Override
public void updateFill(MetaObject metaObject) {
Date date = new Date();
this.setFieldValByName("updateDate", date, metaObject);
}
}
4、BaseEntity.class
import com.baomidou.mybatisplus.annotation.FieldFill;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableLogic;
import lombok.Getter;
import lombok.Setter;
import java.util.Date;
@Getter
@Setter
public class BaseEntity {
@TableField(fill = FieldFill.INSERT)
private Date createDate;
@TableField(fill = FieldFill.INSERT_UPDATE)
private Date updateDate;
@TableLogic
@TableField(fill = FieldFill.INSERT)
private Boolean deleteFlag;
}
5、代码生成器
import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import com.shop.product.common.BaseEntity;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
/**
* @author LongFei
*/
public class CodeGenerator {
public static void main(String[] args) {
FastAutoGenerator.create("jdbc:mysql://00.00.00.00:3306/shop-product", "root", "root")
// 全局配置
.globalConfig((builder) ->
builder.author("LongFei") //作者
.outputDir("D:\\demo_springcloud\\springcloud-alibaba-demo\\shop-product-server\\src\\main\\java")
// .enableSwagger() // 开启 swagger 模式
.disableOpenDir()//禁止打开输出目录
.fileOverride()// 覆盖已生成文件
)
// 包配置
.packageConfig((builder) ->
builder.parent("com.shop.product")
// 设置mapperXml生成路径
.pathInfo(Collections.singletonMap(OutputFile.xml, "D:\\demo_springcloud\\springcloud-alibaba-demo\\shop-product-server\\src\\main\\resources\\mapper"))
)
// 策略配置
.strategyConfig((scanner, builder) ->
builder.addInclude(getTables(scanner.apply("请输入表名，多个英文逗号分隔？所有输入 all")))
.addTablePrefix("t_", "c_")//忽略表前缀
.mapperBuilder().enableBaseResultMap()//启用 BaseResultMap 生成
.controllerBuilder().enableRestStyle().enableHyphenStyle()
.entityBuilder().enableLombok().superClass(BaseEntity.class)
.addSuperEntityColumns("delete_flag", "create_date", "update_date")
.build()
)
.templateEngine(new FreemarkerTemplateEngine())
.execute();
}
// 处理 all 情况
protected static List<String> getTables(String tables) {
return "all".equals(tables) ? Collections.emptyList() : Arrays.asList(tables.split(","));
}
}
配置可见：
6、sql脚本
CREATE TABLE `t_product` (
`id` bigint(12) NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
`price` decimal(10,2) DEFAULT NULL,
`stock` int(255) DEFAULT NULL,
`create_date` datetime DEFAULT NULL,
`update_date` datetime DEFAULT NULL,
`delete_flag` bit(1) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=17 DEFAULT CHARSET=latin1;
7、使用代码生成器，输入表名生成代码
8、测试controller
import cn.hutool.json.JSONUtil;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.shop.product.entity.Product;
import com.shop.product.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.math.BigDecimal;
import java.util.List;
@RestController
@RequestMapping("/product")
public class ProductController {
@Autowired
private IProductService productService;
@GetMapping("/add")
public String add() {
Product product = new Product();
product.setName("11");
product.setPrice(BigDecimal.ONE);
product.setStock(1);
productService.save(product);
return "success";
}
@GetMapping("/list")
public String list() {
IPage<Product> page = new Page<>(1,10);
productService.page(page);
List<Product> records = page.getRecords();
return JSONUtil.toJsonStr(records);
}
}
