使用Java泛型实现实体的转换器

// 源实体类
public class SourceEntity {
    private String name;
    private int age;

    // 省略构造函数、getter和setter
}

// 目标实体类
public class TargetEntity {
    private String fullName;
    private int years;

    // 省略构造函数、getter和setter
}

// 泛型转换器接口
public interface EntityConverter<S, T> {
    T convert(S source);
}

// 具体转换器实现
public class SourceToTargetConverter implements EntityConverter<SourceEntity, TargetEntity> {
    @Override
    public TargetEntity convert(SourceEntity source) {
        TargetEntity target = new TargetEntity();
        target.setFullName(source.getName());
        target.setYears(source.getAge());
        return target;
    }
}

// 使用示例
public class Main {
    public static void main(String[] args) {
        SourceEntity source = new SourceEntity();
        source.setName("John Doe");
        source.setAge(30);

        EntityConverter<SourceEntity, TargetEntity> converter = new SourceToTargetConverter();
        TargetEntity target = converter.convert(source);

        System.out.println("Full Name: " + target.getFullName());
        System.out.println("Years: " + target.getYears());
    }
}
