我遇到的问题

用spring注解来加载bean，都是一个简单的了，但是还是报了这样一个错java.lang.IllegalArgumentException

网上查了一下，说是jdk版本要1.7的，然后我就改了，就好了。

Person.java

1 package com.xiaostudy.service;2 3 import org.springframework.stereotype.Component;4 5 @Component("person")6 public class Person {7     8 }

applicationContext.xml

1 
      2 
     
       9 10     
      11 
     

测试类Test.java

1 package com.xiaostudy.service; 2  3 import org.springframework.context.ApplicationContext; 4 import org.springframework.context.support.ClassPathXmlApplicationContext; 5  6 import com.xiaostudy.service.Person; 7  8 public class Test { 9 10     public static void main(String[] args) {11         ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");12         Person person = ac.getBean("person", Person.class);13         System.out.println(person);14     }15 16 }

错误信息

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [E:\IT\spring3\demo9\bin\com\xiaostudy\service\Person.class]; nested exception is java.lang.IllegalArgumentException

解决问题

1、把eclipse的jdk调整为1.7

2、新建项目的jdk选择1.7
