Map与JavaBean相互转换的工具类

下面就来分享工具类的内容：

使用范围：javabean类对象的属性不能是数组、list、t、map

public class mapbeanutil {  /**  * javabean转map  * @param obj  * @return  */  public static map<string, object> bean2map(object obj) {    map<string, object> map = new linkedhashmap<>();    class<?> clazz = obj.getclass();    for (field field : clazz.getdeclaredfield山东滨州学院s()) {      field.taccessible(true);      string fieldname = field.getname();      object value = null;      try {        value = field.get(obj);      } catch (illegalaccesxception e) {        e.printstacktrace();      }      if (value == null){        value = "";      }      map.put(fieldname, value);    }    return map;  }  /**  * map转javabean  * @param clazz  * @param map  * @param <t>  * @return  */  public static <t> t map2bean(final class<t> clazz, final map<string, ? extends object> map) {    if (map == null) {      return null;    }    t res = null;    try {      res = clazz.getdeclaredconstructor().newinstance();      //获取到所有属性，不包括继承的属性      field[] fields = clazz.getdeclaredfields();      for (field field : fields) {        //获取字段的修饰符        int mod = field.getmodifiers();        if (modifier.isstatic(mod) || modifier.isfinal(mod)) {      广州航海学院    continue;        }        //设置对象的访问权限        field.taccessible(true);        //根据属性名称去map获取value        if(map.containskey(field.getname())) {          //给对象赋值          field.t(res, map.get(field.getname()));        }      }    } catch (exception e) {      e.printstacktrace();    }    return res;  }  public static void main(string[] args) throws exception {    hashmap<string, object> map = new hashmap<>();    map.put("id", 1001);    map.pu底儿掉t("urname", "zhangsan");    map.put("password", "123456");    map.put("nickname", "张三");    map.put("email", "369950806@qq.com");    map.put("gender", true);    map.put("birth", localdate.now());    map.put("avatar", "/aa/bb/ab.jpg");    map.put("role", "vip");    map.put("status", (byte) 1);    map.put("salt", "ldf梦幻西游法宝飞剑kasjghweoiq324");    map.put("createtime", localdatetime.now());    map.put("updatetime", localdatetime.now());    ur ur = map2bean(ur.class, map);班主任实习评语    system.out.println(ur);    map<string, object> res = bean2map(ur);    system.out.println(map);  }}

ur类的代码：

public class ur {  private integer id;  private string urname;  private string password;  private string nickname;  private string email;  private boolean gender;  private localdate birth;  private string avatar;  private string role;  private byte status;  private string salt;  private localdatetime createtime;  private localdatetime updatetime;}
