通过反射对任意class类中方法赋值的方式

import org.apache.commons.lang3.stringutils;

import org.springframework.stereotype.component;

import java.lang.reflect.method;

@component
public class setplatformutils {

public void setval(object obj, string methodname, string platform){
//获取obj代表的实体类class对象
class clazz = obj.getclass();
method method = null;
try {
//获取class对象中的指定的方法
method = clazz.getmethod(methodname, string.class);
//给方法赋值
if (stringutils.isblank(platform)){
method.invoke(obj,c.code.get("1"));
}else{
method.invoke(obj, c.code.get(platform));
}
}
catch (exception e) {
logger.error("存储二级分类的反射工具类出错,obj:{},methodname:{},platform:{},",obj,methodname,platform);
