我只是想知道,我可以将 uri 字符串转换为另一种对象类型吗?
@RequestMapping(value="/key/{keyDomain}", method=RequestMethod.GET)
public String propertyEditor(@PathVariable(value="keyDomain") KeyDomain key, Model model){
model.addAttribute("key", key);
return "propertyEditor";
}
这是我的配置
<beans:bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
<beans:property name="customEditors">
<beans:map>
<!-- <beans:entry key="com.template.baseline.domain.KeyDomain" value="com.template.baseline.propertyEditor.KeyPropertyEditor"/> -->
<beans:entry key="com.template.baseline.domain.KeyDomain">
<beans:ref bean="keyDomainPropertyEditor" />
</beans:entry>
</beans:map>
</beans:property>
</beans:bean>
<!-- key domain property editor bean -->
<beans:bean id="keyDomainPropertyEditor" class="com.template.baseline.propertyEditor.KeyPropertyEditor">
<beans:property name="keyDomain">
<beans:bean class="com.template.baseline.domain.KeyDomain" />
</beans:property>
</beans:bean>
和 propertyEditor 类:
public class KeyPropertyEditor extends PropertyEditorSupport{
private KeyDomain keyDomain;
/**
* example : 10435
* - 10 will be keyId
* - 435 will be baseOfficeId
*/
@Override
public void setAsText(String text) throws IllegalArgumentException{
KeyDomain keyDomain = new KeyDomain();
keyDomain.setKeyId(Integer.parseInt(text.substring(0,1)));
keyDomain.setBaseOfficeId(Integer.parseInt(text.substring(2,4)));
setValue(keyDomain);
}
@Override
public String getAsText() {
KeyDomain value = (KeyDomain) getValue();
return (value != null ? value.toString() : "");
}
public void setKeyDomain(KeyDomain keyDomain) {
this.keyDomain = keyDomain;
}
}
我认为我可以使用属性编辑器将我的 URI 字符串转换为适当的对象类型。我已经实现并配置了 CustomEditorConfigurer,但我总是得到 ConversionNotSupportedException。
如果我在 Controller 中添加 initBinder,一切都会很好:
@InitBinder
public void setBinder(WebDataBinder dataBinder) {
dataBinder.registerCustomEditor(KeyDomain.class, new KeyPropertyEditor());
}
我收到类似这样的警告
WARN : org.springframework.beans.factory.config.CustomEditorConfigurer - Passing PropertyEditor instances into CustomEditorConfigurer is deprecated: use PropertyEditorRegistrars or PropertyEditor class names instead. Offending key [com.template.baseline.domain.KeyDomain; offending editor instance: com.template.baseline.propertyEditor.KeyPropertyEditor@1a271f5
感谢您的回答。
ps:webBindingInitalizer 注入(inject) AnnotationMethodHandlerAdapter
<beans:bean id="AnnotationMethodHandlerAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<beans:property name="webBindingInitializer">
<beans:bean class="com.template.baseline.initialize.CustomWebBindingInitializer" />
</beans:property>
</beans:bean>
和实现
public class CustomWebBindingInitializer implements WebBindingInitializer {
public CustomWebBindingInitializer(){
System.out.println("******** constructor *********");
}
public void initBinder(WebDataBinder binder, WebRequest request) {
System.out.println("******** initBinder *********");
binder.registerCustomEditor(KeyDomain.class, new KeyDomainPropertyEditor());
}
}
最佳答案
CustomEditorConfigurer
与 Web 请求数据绑定(bind)无关。
如果您想注册您的PropertyEditor
全局范围内,您需要实现 WebBindingInitializer
和供应 AnnotationMethodHandlerAdapter
有了它:
<bean
class = "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<proeprty name = "webBindingInitializer">
<bean class = "MyWebBindingInitializer" />
</property>
</bean>
另一种选择是将转换逻辑实现为 Formatter
并通过 FormattingConversionServiceFactoryBean
配置它和<mvc:annotation-driven>
,参见mvc-showcase sample .
