Bean Copy

Bean Copy 是基于"注解+注解处理器"实现的提供和手写代码相同的性能，极大的简化代码，覆盖各种场景的功能。

快速开始

MDP 项目默认引入依赖

使用要求

• JDK8及以上。
• MDP 开发框架，版本 >= 1.5.1.RC7。

1 自动映射

1.1 同名同类型自动映射

1.1.1 基本类型自动映射

基本类型 byte、short、int、long、float 、double、 boolean、char 可实现自动映射，且自动实现拆箱装箱

@Data
public class Source {
    private byte byteValue;
    private short shortValue;
    private int intValue;
    private long longValue;
    private float floatValue;
    private double doubleValue;
    private boolean booleanValue;
    private char charValue;
    private String string;
}
@Data
public class Target {
    private byte byteValue;
    private short shortValue;
    private int intValue;
    private long longValue;
    private float floatValue;
    private double doubleValue;
    private boolean booleanValue;
    private char charValue;
    private String string;
