hibernate - 在 JSF1.2 + seam 中按名字搜索

Question

我正在尝试在我的用户列表页面中按名字进行搜索。在将搜索选项放入用户列表页面之前，用户列表页面工作正常。在 list.xhtml 中添加代码以进行搜索后，页面显示以下错误，请求处理期间出现异常：由 javax.servlet.ServletException 引起，消息为：“/secure/admin/user/customer/customerList.xhtml @70,70 value ="#{userByFirstNameAction.firstName}"：在类型 org.javassist.tmp.java.lang.Object_$$_javassist_seam_25 上找不到属性“firstName”

我的列表页面是：customerList.xhtml

    <h:form class="input-list" id="searchUser" style="width:100%;"
        name="searchUser">
        <div class="search_button">
            SEARCH BY FIRST NAME :
            <h:inputText tabindex="1" id="firstName" type="text"
                value="#{userByFirstNameAction.firstName}" required="true">
                <f:validateLength minimum="3" maximum="20" />
            </h:inputText>
        </div>

        <h:commandButton value="Search" tabindex="2"
            action="#{userByFirstNameAction.retrieveCustomersByFirstName}">
        </h:commandButton>
    </h:form>

userByFirstNameAction.java ：

    @Name("userByFirstNameAction")
    @Stateless
    @AutoCreate
    public class UserByFirstNameActionImpl implements UserByFirstNameAction {


        private UserTypeEnum userType;

        @In
        private UserService userService;

        //@In(value = "firstName", scope = ScopeType.CONVERSATION, required = false)
        private String firstName;

        /**
         * 
         */
        private static final long serialVersionUID = 8282995226262125676L;


        public String getFirstName() {
            return firstName;
        }

        public void setFirstName(String firstName) {
            this.firstName = firstName;
        }

            @Override
        public List<User> retrieveCustomersByFirstName(String firstName) {
            //this.userType = UserTypeEnum.CUSTOMER;
            return userService.findByFirst(firstName);      
        }

    }

@Jan 谢谢你的时间..

我已将 Get/Set for firstname 放在 bean 类中...

这里供您参考

        public String initCustomer();

        public List<User> getEmployeesByFirstName();

        public List<User> getCustomersByFirstName();

        public List<User> retrieveEmployeesByFirstName();

        // public List<User> retrieveCustomersByFirstName();

        public List<User> retrieveCustomersByFirstName(String firstName);
