java字符串反射转换对象

业务对象类

import java.io.Serializable;

public class Question implements Serializable {

	private static final long serialVersionUID = 1L;

	private String seq;
	
	private String question;
	
	private String ans;

	public String getAns() {
		return ans;
	}

	public void setAns(String ans) {
		this.ans = ans;
	}

	public String getSeq() {
		return seq;
	}

	public void setSeq(String seq) {
		this.seq = seq;
	}

	public String getQuestion() {
		return question;
	}

	public void setQuestion(String question) {
		this.question = question;
	}
}

对象装换测试类（变量名很草哦）

import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class RefTest {

	public static void main(String[] args) throws Exception {
		String[] sr = new String[]{"序号#seq,问题#question,答案#ans","1,问题1,abc","2,问题2,def"};
		List<Question> ql = buildT(Question.class, sr);
		System.err.println();
	}
	
	public static <T> List<T> buildT(Class clazz, String[] sr) throws Exception {
		List<T> list = new ArrayList<T>();
		String[] sa = sr[0].split(",");
		String s = null;
		Map<Integer, String> map = new HashMap<Integer, String>();
		for(int i = 0, len = sa.length; i < len; i++){
			s = sa[i];
			String[] _sa = s.split("#", 2);
			map.put(i, _sa[1]);
		}
		for(int i = 1, len = sr.length; i < len; i++){
			s = sr[i];
			String[] _sa = s.split(",");
			T t = (T) clazz.newInstance();
			
			for(int j = 0; j < _sa.length; j++){
				Field fi = clazz.getDeclaredField(map.get(j));
				fi.setAccessible(true);
				fi.set(t, _sa[j]);
			}
			list.add(t);
		}
		return list;
	}
}
