Java使用ORM Bee自动生成Javabean.

Java使用ORM Bee自动生成Javabean.

配置数据库连接,添加了pom.xml依赖后,就可以写Java代码,自动生成Javabean了.

还可以生成字段文件, 这样可以避免硬编码引用字段,速度也比反射快.

java 复制代码

package org.teasoft.exam.bee.osql.autogen;

import org.teasoft.bee.osql.BeeException;
import org.teasoft.honey.osql.autogen.GenBean;
import org.teasoft.honey.osql.autogen.GenConfig;

public class GenBeanSimple3 {
	public static void main(String[] args) {
		try {

			GenConfig config = new GenConfig();
			config.setGenToString(true);// 生成toString方法
			config.setGenComment(true); // 可生成注释
			config.setCommentPlace(1); // 注释的位置

			GenBean genBean = new GenBean(config);
			// 生成字段文件, 这样可以避免硬编码引用字段,速度也比反射快.
			config.setGenFieldFile(true);
			config.setOverride(true); // 是否覆盖原来的文件
			config.setUpperFieldNameInFieldFile(true);

			genBean.genSomeBeanFile("exam");

			// it is easy way. 最简单的用法,所有的都用默认配置.
//			new GenBean().genSomeBeanFile("orderhistory");

		} catch (BeeException e) {
			e.printStackTrace();
		}
	}
}

生成的Javabean:

生成字段文件

config.setUpperFieldNameInFieldFile(true);****//属性名用大写.

java 复制代码

package entity.field;

/**
 * Relative field name for Javabean Exam
 * @author Honey
 * Create on 2024-12-13 22:30:39
 */
public interface Exam_F {

	String ID = "id";

	String USERID = "userid";

	String LAST_NAME = "lastName";

	String FIRST_NAME = "firstName";

	String BIRTH_DATE = "birthDate";

	String SEX = "sex";

	String GROUP_ID = "groupId";

	String GROUP_NAME = "groupName";

	String CHECK_DATE = "checkDate";

	String CHECK_TIME = "checkTime";

	String OPERATOR = "operator";

	String UPDATETIME = "updatetime";

	String CHECK_DATA = "checkData";

	String ENTITY_NAME = "Exam";
	String TABLE_NAME = "exam";
	String ALL_NAMES = "id,userid,lastName,firstName,birthDate,sex,groupId,groupName,checkDate,checkTime,operator,updatetime,checkData";
}

另外一种风格. 属性名和字符串是一样的. 用一样就好了,可必让自己那么累,同时看两种风格的命名呢,达到去硬编码的目的就好.
