我在尝试使用Spring Framework进行依赖注入时遇到此错误
Bean类[Person]的无效属性'messageService'：Bean
属性“ messageService”不可写或设置无效
方法。您是说“ messageService”吗？
这是我班的人：
public class Person {
private MessageService messageService;
public void setMessageService(MessageService messageService){
this.messageService = messageService;
}
public MessageService getMessageService() {
return this.messageService;
}
public void Chao(String Subject, String Message)
{
messageService.sendMessage(Subject,Message);
}
}
这是我的Beans.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="email" class="Email"></bean>
<bean id="Person" class="Person">
<property name="messageService " ref="email"></property>
</bean>
</beans>
最后是主班
public class Main {
public static void main(String args[]) throws Exception{
ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
Person test = (Person) context.getBean("Person");
test.Chao("abc","abc");
}
}
MessageService是接口，类Email implements MessageService有人可以告诉我我在做什么错吗？非常感谢你
最佳答案
name="messageService "的末尾有一个空格。请删除它。
