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.
可参考: https://gitee.com/automvc/bee
https://github.com/automvc/bee
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
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();
}
}
}DB:
生成的Javabean:

}生成字段文件
config.setUpperFieldNameInFieldFile(true);****//属性名用大写.

}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.
