jsp部分代码：

<!--个人信息-->
            <div class="thumbnail">
                <img src="/smv/imgs/users/${sessionScope.user.photo}" alt="..." class="img-circle" width="100px" height="120px">
                <div class="caption">
                    <h3>${sessionScope.user.name}</h3>
                    <p>身份证:${sessionScope.user.no}</p>
                    <p>性别:${sessionScope.user.sex?"男":"女"}</p>
                    <p>拥有车辆:${cartotal}辆</p>
                    <p>
                        <a href="#" class="btn btn-primary" role="button">更新</a>
                        <a href="#" class="btn btn-primary" role="button">驾驶证信息</a>
                    </p>
                </div>
            </div>

实体类：

public class User {
    private Integer id;
    private String name;
    private String no;
    private Integer sex;
    private String photo;
    private String pwd;

问题所在：

这里实体类定义的sex属性为int型，但是 jsp 代码中${sessionScope.user.sex?“男”:“女”}的sex为String型，所以就会造成类型转换错误
