JSF 实体转换错误:丰富建议框转换错误设置值“*”对于“空转换器”
我正在使用rich:suggestionbox。
- 从建议框中选择建议
- 然后保存我的表单
- 它会引发验证错误,提示“null Converter”的“rich suggestbox Conversion Error”设置值“568-UNIMED-2005”。
帮助
- 我需要有关我的代码有什么问题的
- 吗?如何解决这个问题?
这是我的 LcInfo
bean
@AutoCreate
@Scope(ScopeType.CONVERSATION)
@Name("lcInfo")
@Entity
@Table(name="lc_info")
public class LcInfo implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private ItemIndentMast itemIndentMastBean;
public LcInfo() {
}
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(unique=true, nullable=false)
public Integer getId() {
return this.id;
}
public void setId(Integer id) {
this.id = id;
}
//bi-directional many-to-one association to ItemIndentMast
@ManyToOne
@JoinColumn(name="item_indent_mast", nullable=false)
public ItemIndentMast getItemIndentMastBean() {
return this.itemIndentMastBean;
}
public void setItemIndentMastBean(ItemIndentMast itemIndentMastBean) {
this.itemIndentMastBean = itemIndentMastBean;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + id;
return result;
}
@Override
public boolean equals(Object object) {
if (this == object) return true;
if (object == null) return false;
if (getClass() != object.getClass()) return false;
LcInfo other = (LcInfo) object;
return id.equals(other.id);
}
}
这是我的带有 rich:suggestionbox 的 XHTML 源代码。
<h:inputText value="#{lcInfo.itemIndentMastBean}" id="itemIndentMastBean" required="true"/>
<rich:suggestionbox for="itemIndentMastBean"
suggestionAction="#{lcInfoController.suggestion}"
var="result"
fetchValue="#{result}"
minChars="3"
nothingLabel="No capitals found" >
<f:facet name="header">
<h:outputText value="Select Indent Number" style="font-size: 10px; padding-left: 5px"/>
</f:facet>
<h:column>
<h:outputText value="#{result}" />
</h:column>
</rich:suggestionbox>
这是控制器代码如何从控制器加载建议
@Name("lcInfoController")
@Scope(ScopeType.CONVERSATION)
@AutoCreate
public class LcInfoController {
public List<ItemIndentMast> suggestion(Object query) {
String queryText = query.toString();
if(StringUtils.isBlank(queryText) || queryText.length() < 3) {
return Collections.emptyList();
}
return itemIndentMastService.filterIndent(queryText+"%");
}
}
I am using rich:suggestionbox.
- Select a suggestion from the suggestion box
- Then save my form
- It raises the validation error saying
rich suggestionbox Conversion Error setting value '568-UNIMED-2005' for 'null Converter'
.
I need help with
- What is wrong with my code?
- How to fix the issue?
Here is my LcInfo
bean
@AutoCreate
@Scope(ScopeType.CONVERSATION)
@Name("lcInfo")
@Entity
@Table(name="lc_info")
public class LcInfo implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private ItemIndentMast itemIndentMastBean;
public LcInfo() {
}
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(unique=true, nullable=false)
public Integer getId() {
return this.id;
}
public void setId(Integer id) {
this.id = id;
}
//bi-directional many-to-one association to ItemIndentMast
@ManyToOne
@JoinColumn(name="item_indent_mast", nullable=false)
public ItemIndentMast getItemIndentMastBean() {
return this.itemIndentMastBean;
}
public void setItemIndentMastBean(ItemIndentMast itemIndentMastBean) {
this.itemIndentMastBean = itemIndentMastBean;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + id;
return result;
}
@Override
public boolean equals(Object object) {
if (this == object) return true;
if (object == null) return false;
if (getClass() != object.getClass()) return false;
LcInfo other = (LcInfo) object;
return id.equals(other.id);
}
}
Here is my XHTML source with a rich:suggestionbox.
<h:inputText value="#{lcInfo.itemIndentMastBean}" id="itemIndentMastBean" required="true"/>
<rich:suggestionbox for="itemIndentMastBean"
suggestionAction="#{lcInfoController.suggestion}"
var="result"
fetchValue="#{result}"
minChars="3"
nothingLabel="No capitals found" >
<f:facet name="header">
<h:outputText value="Select Indent Number" style="font-size: 10px; padding-left: 5px"/>
</f:facet>
<h:column>
<h:outputText value="#{result}" />
</h:column>
</rich:suggestionbox>
Here is the controller code how suggestions are loaded from controller
@Name("lcInfoController")
@Scope(ScopeType.CONVERSATION)
@AutoCreate
public class LcInfoController {
public List<ItemIndentMast> suggestion(Object query) {
String queryText = query.toString();
if(StringUtils.isBlank(queryText) || queryText.length() < 3) {
return Collections.emptyList();
}
return itemIndentMastService.filterIndent(queryText+"%");
}
}

这就是我最后想到的: Seam:创建自定义转换器
This is what I came up with in the end: Seam: Creating a custom converter
使输入接收字符串值而不是 bean :
更改
为
JSF 不知道如何处理您的 ItemIndentMast BEAN。
或者,您可以为该 bean 创建一个转换器(将字符串转换为 bean)

make the input recieve a string value and not a bean :
change
to
JSF does not know how handle your ItemIndentMast BEAN.
alternatevly you can create a converter for that bean (convert string to bean)
