反射获取属性值

简单的通过动态属性名获取属性值
一个简单的JAVA对象

public class platformBean {
    
    private String platName1;
    
    private String platLink1;
    
    private String platName2;
    
    private String platLink2;
    
    private String platName3;
    
    private String platLink3;
    
    private String platName4;
    
    private String platLink4;
    
    private List listPlat;
}

public class tempPlat {
    private String platName;
    private String platLink;
}
