在Test文件夹中创建测试类

java 复制代码

import org.springframework.boot.test.context.SpringBootTest;

//此处代码可以自动生成系列文件
@SpringBootTest
public class TestGenerator {
    @Test
    public void testGenerator(){
        FastAutoGenerator.create("jdbc:mysql://localhost:3306/mybatis?serverTimezone=GMT%2B8", "root", "root")
                .globalConfig(builder -> {
                    builder.author("jiangnan") // 设置作者

                            .fileOverride() // 覆盖已生成文件
                            .outputDir(".\\src\\main\\java"); // 指定输出目录
                })
//不了解忽略

                .packageConfig(builder -> {
                    builder.parent("com.yase") // 设置父包名

                })
                .strategyConfig(builder -> {
                    builder.addInclude("i_emp") // 设置需要生成的表名
                            .addTablePrefix("i_", "c_"); // 设置过滤表前缀
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
}
