方式一: 利用fastjson 把对象转化为map
/**
*
* @methodname: getuserinfodatabyuserid
* @description: 根据useid查询用户信息，封装成map key：属性名，value：属性值
* home.php?mod=space&uid=952169 userid 用户userid
* @return
*/
public map getuserinfodatabyuserid(string userid) {
map usermap = new hashmap();
bsysuser bsysuser = new bsysuser();
if (stringutils.isnoneblank(userid)) {
bsysuser = bsysuserservice.selectbykey(userid);
if (null != bsysuser) {
//usermap = new beanmap(bsysuser);
usermap = json.parseobject(json.tojsonstring(bsysuser), new typereference>() {
});
}
}
return usermap;
}
方式二: 利用反射进行转换
public class beanmaputilbyreflect {
/**
* 对象转map
* @param object
* @return
* @throws illegalaccessexception
*/
public static map beantomap(object object) throws illegalaccessexception {
map map = new hashmap();
field[] fields = object.getclass().getdeclaredfields();
for (field field : fields) {
field.setaccessible(true);
map.put(field.getname(), field.get(object));
}
return map;
}
/**
* map转对象
* @param map
* @param beanclass
* @param
* @return
* @throws exception
*/
public static t maptobean(map map, class beanclass) throws exception {
t object = beanclass.newinstance();
field[] fields = object.getclass().getdeclaredfields();
for (field field : fields) {
int mod = field.getmodifiers();
if (modifier.isstatic(mod) || modifier.isfinal(mod)) {
continue;
}
field.setaccessible(true);
if (map.containskey(field.getname())) {
field.set(object, map.get(field.getname()));
}
}
return object;
}
}
