在Spring项目中自动想用注解的方式，在controller里面注入Service但是报错，错误信息如下:

[WARNING] Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'indexController': Unsatisfied dependency expressed through field 'personService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.wdg.person.api.IPerson' available: expected at least 1 bean which qualifies as autowire candidate.

错误原因:

package com.wdg.person.impl;

import org.springframework.stereotype.Service;

import com.wdg.person.api.IPerson;
import com.wdg.person.domain.Person;

@Service
public class PersonDao implements IPerson{

	@Override
	public Person selectPersonByRowguid(String rowguid) {
		System.out.println("niaho");
		return null;
	}

	@Override
	public Person selectPersonbyUserName(String username) {
		// TODO Auto-generated method stub
		return null;
	}
}

在class上面没有添加@Service注解

同时检查:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans.xsd
                         http://www.springframework.org/schema/context
                         http://www.springframework.org/schema/context/spring-context-3.0.xsd">
	<!-- <context:component-scan base-package="com.wdg.person.impl"></context:component-scan> -->
	<bean class="com.wdg.person.impl.PersonDao"></bean>

</beans>

无论是扫包的@Service

bean class方式注入的是class上面可以不用任何的注释

无论是怎么样，我们在xml中的配置扫包或者是bean class必须有其中一个

希望对你有所帮助
