后台部分
开发步骤
-
1、创建用户表 -
2、创建项目 -
3、使用代码生成器根据数据库表生成各种类 -
4、导入各种maven坐标 -
5、开始开发
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for users
-- ----------------------------
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
`uid` varchar(255) NOT NULL COMMENT 'id',
`username` varchar(255) DEFAULT NULL COMMENT '用户名',
`password` varchar(255) DEFAULT NULL COMMENT '密码',
`enabled` tinyint(255) DEFAULT NULL COMMENT '状态',
`role` varchar(255) DEFAULT NULL,
PRIMARY KEY (`uid`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of users
-- ----------------------------
BEGIN;
INSERT INTO `users` VALUES ('uid_003269d7-762e-40e2-b18c-b62103d9050a', 'admin', '$2a$10$QPi7uqqOvT47DQTSKprdf.X4p8p7naJB1RdZdI6M/I.L1DAND3H.O', 0, 'admin');
INSERT INTO `users` VALUES ('uid_2a481559-dbab-416d-8e01-c1dc0542575b', 'admin2', '$2a$10$Zn/cZNckZ.d.BNy4vuoSIuslOrimIQTIqJUBLqH2sk9ldjDkRFK36', 0, 'admin');
COMMIT;
SET FOREIGN_KEY_CHECKS = 1;
2、创建项目忽略
3、使用代码生成器根据数据库表生成各种类 CodeGenerator.java
package com.example.maxcc;
import java.util.ArrayList;
import java.util.Scanner;
import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;
import com.baomidou.mybatisplus.core.toolkit.StringPool;
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.FileOutConfig;
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.TemplateConfig;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public static String scanner(String tip) {

mpg.setPackageInfo(pc);
// 自定义配置

// to do nothing
}
};
// 如果模板引擎是 freemarker
String templatePath = "/templates/mapper.xml.ftl";
// 如果模板引擎是 velocity
// String templatePath = "/templates/mapper.xml.vm";
// 自定义输出配置

focList.add(new FileOutConfig(templatePath) {
@Override
public String outputFile(TableInfo tableInfo) {
// 自定义输出文件名 ， 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化！！
return projectPath + "/src/main/resources/mapper/" + tableInfo.getEntityName() + "Mapper"

}
});
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
// 配置模板
TemplateConfig templateConfig = new TemplateConfig();
templateConfig.setXml(null);
mpg.setTemplate(templateConfig);
// 策略配置
StrategyConfig strategy = new StrategyConfig();
//数据库表映射到实体的命名策略
strategy.setNaming(NamingStrategy.underline_to_camel);
//数据库表字段映射到实体的命名策略
strategy.setColumnNaming(NamingStrategy.no_change);

//生成 @RestController 控制器
strategy.setRestControllerStyle(true);
strategy.setInclude(scanner("表名，多个英文逗号分割").split(","));
strategy.setControllerMappingHyphenStyle(true);
//表前缀
//strategy.setTablePrefix("tb_");
mpg.setStrategy(strategy);
mpg.setTemplateEngine(new FreemarkerTemplateEngine());
mpg.execute();
}
}
修改好上面你数据库的信息和类的路径，然后直接运行这个类，在控制台输入数据库对应的表名字即可，系统会在自动根据你的数据库表生成该表对应的 pojo类，mapper文件和mapper类，service类和实现类以及对应的controller层的类。 4、导入各种maven坐标 pom.xml
