博主在尝试使用Java反射操作私有成员变量时遇到'Class can not access a member with modifiers "private"'的错误。经过多次尝试和排查，发现问题是由于结构函数被定义为private导致的。将这部分注释掉后，问题成功解决。文中提供了具体的反射调用代码。

我有个类利用反射实现

一直报错

Class can not access a member with modifiers "private"

按照网上方法试验了都没有解决.

代码如下:

package single;

/**

public class WX_Token {

    /**
     * @return the WXCOR_Token
     */
    public String getWXCOR_Token() {
        return WXCOR_Token;
    }

    /**
     * @param WXCOR_Token the WXCOR_Token to set
     */
    public void setWXCOR_Token(String WXCOR_Token) {
        this.WXCOR_Token = WXCOR_Token;
    }

    private WX_Token() {

    }

        //用单例实现 双重检查[推荐用]  
        private static volatile WX_Token instance;
    
        public static WX_Token getInstance() {
    
            WX_Token singleton = WX_Token.instance;
    
            if (singleton == null) {
