将变量从一个POJO复制到另一个POJO

public class SourcePOJO {
    private String name;
    private int age;
    // 省略getter和setter方法
}

public class TargetPOJO {
    private String name;
    private int age;
    // 省略getter和setter方法
}

public class CopyUtils {
    public static void copyProperties(SourcePOJO source, TargetPOJO target) {
        target.setName(source.getName());
        target.setAge(source.getAge());
    }
}

// 使用示例
SourcePOJO source = new SourcePOJO();
source.setName("John");
source.setAge(25);

TargetPOJO target = new TargetPOJO();
CopyUtils.copyProperties(source, target);

// 使用Apache Commons BeanUtils库进行变量复制
import org.apache.commons.beanutils.BeanUtils;

public class SourcePOJO {
    private String name;
    private int age;
    // 省略getter和setter方法
}

public class TargetPOJO {
    private String name;
    private int age;
    // 省略getter和setter方法
}

// 使用示例
SourcePOJO source = new SourcePOJO();
source.setName("John");
source.setAge(25);

TargetPOJO target = new TargetPOJO();
BeanUtils.copyProperties(target, source);
