FreeMarker模板错误！在struts2

我在我的课堂中使用基于sturts 2注解的验证，而显示动作错误我得到了这个奇怪的“FreeMarker模板错误！”这是我的实体班。FreeMarker模板错误！在struts2

@Entity 
public class User implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private Long userid; 
    private String userPhoneNumber; 
    private String userName; 
    private String password; 
    private String full_name; 
    private String useremail; 

    @OneToOne 
    private userType usertypeid; 

    public Long getUserid() { 
     return userid; 
    } 

    public void setUserid(Long userid) { 
     this.userid = userid; 
    } 

    public String getUserPhoneNumber() { 
     return userPhoneNumber; 
    } 

    @RequiredStringValidator(message = "Enter Phone Number",type = ValidatorType.FIELD) 
    public void setUserPhoneNumber(String userPhoneNumber) { 
     this.userPhoneNumber = userPhoneNumber; 
    } 

    public String getUserName() { 
     return userName; 
    } 

    @RequiredStringValidator(message = "Enter User Name",type = ValidatorType.FIELD) 
    public void setUserName(String userName) { 
     this.userName = userName; 
    } 

    public String getPassword() { 
     return password; 
    } 

    @RequiredStringValidator(message = "Enter Password",type = ValidatorType.FIELD) 
    public void setPassword(String password) { 
     this.password = password; 
    } 

    public String getFull_name() { 
     return full_name; 
    } 

    @RequiredStringValidator(message = "Enter Full Name",type = ValidatorType.FIELD) 
    public void setFull_name(String full_name) { 
     this.full_name = full_name; 
    } 

    public String getUseremail() { 
     return useremail; 
    } 

    @RequiredStringValidator(message = "Enter Email Id",type = ValidatorType.FIELD) 
    @EmailValidator(message = "Enter Valid Email Id",type = ValidatorType.FIELD) 
    public void setUseremail(String useremail) { 
     this.useremail = useremail; 
    } 

    public userType getUsertypeid() { 
     return usertypeid; 
    } 

    public void setUsertypeid(userType usertypeid) { 
     this.usertypeid = usertypeid; 
    } 

}

这是我在struts.xml文件操作代码

<action name="saveorupdate" class="com.elegant.purchasemodule.purchasemasters.user.UserAction" 
      method="saveOrUpdate"> 
    <interceptor-ref name="defaultStackHibernateStrutsValidation"/> 
    <result name="input">/AddUser.jsp</result> 
    <result name="success" type="redirect">userlist</result> 
</action>

这是我的jsp页面

这个例外在告诉你什么地方去寻找错误：

org.apache.jasper.JasperException: Expression eKey is undefined on line 32, column 23 in template/simple/fielderror.ftl. - Class: freemarker.core.TemplateObject

罪魁祸首是一个fieldError有不匹配fieldName。测试（评价）之后，它被证明是full_name，appearently 是不正确地通过整个链处理下划线：

<s:textfield id="full_name" name="full_name" ... /> 
... 
<s:fielderror fieldName="full_name" cssClass="alert-danger"/>

full_name应该再改为fullName只要与可变和它的getter和setter为了工作：

<s:fielderror fieldName="fullName" cssClass="alert-danger"/>

同时确保掌握所有最新和排列的支杆库和插件，有外部依赖的正确版本（Hibernate验证等）

这么说，我想给你一个有关变量的命名夫妇建议的：

总是使用驼峰与多个单词的变量：password是password（一个字，虽然复合材料），但是username和useremail应该是userName和userEmail。您已经使用3个不同的约定6个变量的单一类的......
因为这些都是User类的变量，避免在变量名冗余user：用户ID = ID，用户名=名称，userPhoneNumber = phoneNumber等...... 如果您在JSP中为了获得更高的可读性而这样做，那么请避免使用可能混淆的<s:push>标签。

如果您正在开始，更改数据库列名不应该是一个痛苦......否则，请为您的下一个项目保留此建议。

PS：注意，使用JPA和与此设置在persistence.xml中Hibernate，您可以使用驼峰变量，并强调了列名（在实体phoneNumber，phone_number数据库）自动：

<property name="hibernate.ejb.naming_strategy" 
     value="org.hibernate.cfg.ImprovedNamingStrategy" />

尝试删除从一个full_name，看看它是不是罪魁祸首。我跑出了想法，如果你有另一个WAR它的工作，仔细检查配置，库，注释，jsp代码的每一个不同... –

谢天谢地终于解决了。罪魁祸首是full_name.Just删除了该变量的验证。我不知道为什么和下划线导致了一个大问题。你非常感谢你持续的帮助，并且耐心倾听我的业余话语。 –

感谢您的大力帮助。 –
