利用java反射机制对多属性javabean赋值

public class ReflectMatch {

//封装属性
private Map<String,Field> fieldMap = new HashMap<String,Field();
//封装属性的set方法
private Map<String,Method> methMap=new HashMap<String,Method>();

/*c:为赋值对象，
*values为给属性要赋的值，put('m1',1);put('m2',2),m1、m2等为属性
*/
public void setValue(Object c,Map values){
try{
Field[] fields = c.getClass().getDeclaredFields();

Method[] methods = c.getClass().getDeclaredMethods();

for(Field field : fields){
String attri = field.getName();
fieldMap.put(attri.toLowerCase(), field);
for(Method method : methods){
String meth = method.getName();
//匹配set方法
if(meth != null
&& "set".equals(meth.substring(0, 3))
&& Modifier.isPublic(method.getModifiers())
&& ("set"+Character.toUpperCase(attri.charAt(0))+attri.substring(1)).equals(meth)){
methodMap.put(attri.toLowerCase(), method);
break;
}
}
}

//2、属性赋值
for(Iterator it = values.keySet().iterator();it.hasNext();){
String name = (String)it.next();
String value = (String)values.get(name);

if (value == null)
continue;
value = value.trim();
name = name.trim();

Field field = fieldMap.get(name.toLowerCase());
if(field == null) continue;
Method method = methodMap.get(name.toLowerCase());
if (method == null) continue;
fill(c,field,method,value);
}

}catch(Exception e){
e.printStackTrace();
}
