最近在使用适配器接收参数的时候,发现一个很奇怪的现象: 页面传过来的参数在反序列化的时候 对 具有相同变量名的对象都会尝试转换,导致报了类型转换错误
想知道有没有什么方法解决这一问题
上代码

入口函数的定义为：
.

  @At(value = "/?")
  @PUT
  public void update(@Param("..") UserRegistVo userVo) {
    //do other
  }

这是页面传来的参数对象

public class UserRegistVo {

  private User user;

  private String[] roles;

  private String userid;

}

这是 user 对象

public class User  {
    private String name;
    private List<UserRole> roles;
}

这是报错信息

反序列化的时候 找到 UserRegistVo 的 roles 了 还会继续试图转化成 User 对象里 roles,我并不想让他转化,有什么办法吗
