[解决办法]
可以考虑使用java的反射机制
[解决办法]
package test;
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.util.HashMap;
import java.util.Map;
public class Test {
public static void main(String[] args) throws ClassNotFoundException,
InstantiationException, IllegalAccessException, IllegalArgumentException,
InvocationTargetException, SecurityException, NoSuchFieldException {
Map <String, Object> map = new HashMap <String, Object> ();
map.put( "name ", "abc ");
map.put( "age ", 20);
Student stu = new Student();
Class clazz = Class.forName( "test.Student ");
for (Map.Entry <String, Object> entry : map.entrySet()) {
Field field = clazz.getDeclaredField(entry.getKey());
field.setAccessible(true);
field.set(stu, entry.getValue());
}
System.out.println(stu.getName());
System.out.println(stu.getAge());
}
}
class Student {
private String name;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
