使用Nutz的Mirror.me获取所有字段，然后字段上有一个自定义注解，但是通过field.isAnnotationPresend()方法判断为false
代码实例如下：

public @interface IsTemplate {
}

@Table("ad_account")
public class AccountModel extends BaseModel {
    @Name
    @IsTemplate
    private String passport;
    @Column
    @Default("0")
    @IsTemplate
    private int noAuth;
    @Column
    private String city;

    public String getPassport() {
        return passport;
    }

    public void setPassport(String passport) {
        this.passport = passport;
    }

    public int getNoAuth() {
        return noAuth;
    }

    public void setNoAuth(int noAuth) {
        this.noAuth = noAuth;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public static void main(String[] args) {
        for (Field field : Mirror.me(AccountModel.class).getFields()) {
            System.out.println(field.getName() + field.isAnnotationPresent(Column.class)); // 可以正确判断Column的注解字段
            System.out.println(field.getName() + field.isAnnotationPresent(IsTemplate.class)); // 这里判断自定义注解，始终是false

        }
    }
}
