为什么我要采取行动PropertyEditorSupport
?任何人都可以在这里帮助我,因为我是春天的新手。下面是错误报告
线程“main” org.springframework.beans.factory.BeanCreationException 中的异常:使用
'cont'
类路径资源 [propertyEdit.xml
] 中定义的名称创建 bean 时出错:bean 初始化失败;嵌套异常是 org.springframework.beans.TypeMismatchException: 无法将类型 [] 的属性值转换为属性java.lang.String
所需的类型;嵌套异常是 java.lang.IllegalArgumentException: 原因:org.springframework.beans.TypeMismatchException:无法将类型的属性值转换为属性所需的类型;嵌套的[Phone]
'phone'
888-555-1212
[java.lang.String]
[Phone]
'phone'
例外是 java.lang.IllegalArgumentException: 888-555-1212 引起:java.lang.IllegalArgumentException:888-555-1212 在 java.beans.PropertyEditorSupport.setAsText(未知来源) 在 org.springframework.beans.TypeConverterDelegate.doConvertTextValue(TypeConverterDelegate.java:326) 在 org.springframework.beans.TypeConverterDelegate.doConvertValue(TypeConverterDelegate.java:305) 在 org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:192) 在 org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:138) 在 org.springframework.beans.BeanWrapperImpl.convertForProperty(BeanWrapperImpl.java:380) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1111) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:861) 在 org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:421) 在 org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:251) 在 org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:156) 在 org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:248) 在 org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:160) 在 org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:287) 在 org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:352) 在 org.springframework.context.support.ClassPathXmlApplicationContext.(ClassPathXmlApplicationContext.java:91) 在 org.springframework.context.support.ClassPathXmlApplicationContext.(ClassPathXmlApplicationContext.java:75) 在 org.springframework.context.support.ClassPathXmlApplicationContext.(ClassPathXmlApplicationContext.java:65) 在 ShowContact.main(ShowContact.java:9)
我以下列方式使用了 java.beans.PropertyEditorSupport
public class PhoneEditor extends java.beans.PropertyEditorSupport{
public void setAsTest(String textValue)
{
String stripped = stripNonNumeric(textValue);
String areaCode=stripped.substring(0,3);
String prefix=stripped.substring(3,6);
String number=stripped.substring(6);
Phone phone=new Phone(areaCode,prefix,number);
setValue(phone);
}
private String stripNonNumeric(String original)
{
StringBuffer allNumeric = new StringBuffer();
for(int i=0; i<original.length(); i++)
{
char c=original.charAt(i);
if(Character.isDigit(c))
{
allNumeric.append(c);
}
}
return allNumeric.toString();
}
}
我的配置文件如下
<bean name="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
<property name="customEditors">
<map>
<entry key="Phone">
<bean id="Phone" class="PhoneEditor">
</bean>
</entry>
</map>
</property>
</bean>
<bean id="cont" class="Contact">
<property name="name" value="Dhirendra"/>
<property name="phone" value="888-555-1212" />
</bean>
</beans>
电话类在下面
public class Phone {
private String areaCode;
private String prefix;
private String number;
public Phone(){}
public Phone(String areaCode, String prefix, String number)
{
this.areaCode=areaCode;
this.prefix=prefix;
this.number=number;
}
public String getPhoneNumber()
{
return prefix+"-"+areaCode+"-"+number;
}
}
我用下面的方式打电话
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.beans.factory.config.CustomEditorConfigurer;
public class ShowContact {
public static void main(String[] args)
{
ApplicationContext context = new ClassPathXmlApplicationContext("propertyEdit.xml");
Employee employee=(Employee)context.getBean("cont");
employee.PrintEmpDetails();
}
}
下面是我正在调用的联系人类
public class Contact implements Employee {
private Phone phone;
private String name;
public void setPhone(Phone phone) {
// TODO Auto-generated method stub
this.phone=phone;
}
public void setName(String name) {
// TODO Auto-generated method stub
this.name=name;
}
public void PrintEmpDetails()
{
System.out.println("Name of Employee :"+ name);
System.out.println("Contact Number of Employee :"+ phone.getPhoneNumber());
}
}
