一个简单的spring.

SpringTest

package lee;

import org.crazyit.app.service.PersonService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class SpringTest {
	
	public static void main(String [] args){
		//创建Spring的ApplicationContext.
		ApplicationContext ctx = new ClassPathXmlApplicationContext("bean.xml");
		//输出Spring容器
		System.out.println("1");
		PersonService p = ctx.getBean("personService",PersonService.class);
		p.info();
	}
}

PersonService

package org.crazyit.app.service;

public class PersonService {
	
	private String name;
	
	public void setName(String name)
	{
		this.name=name;
	}
	
	//测试Person类的info方法.
	public void info()
	{
		System.out.println("此人名为:"+name);
	}

}

空指针了。看看你的 classpath 下是不是有多个 spring 配置文件

按照书上的源码来配置的，一样出错

web.xml是怎么配置的啊

书上提供的源码没说那个，也就没配置.

引用 3 楼 xuefeng0707 的回复:

<bean id="personService" class=" org.crazyit.app.service.PersonService">

class里似乎多了个空格。

太仔细了，我回去检查下，谢谢

PersonService类中的name没有get 方法。。。

setter注入，只需要set方法就行，不用get方法
