spring注入jdbcTemplate时一直为空指针，求大牛指导

Question

已经在spring配置文件中配置了jdbcTemplate的bean，但是在测试类中jdbcTemlpate的注入报空指针

 <?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.xsd ">

    <!-- 配置spring的jdbcTemplate-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!-- 设置spring扫包路径 -->
    <context:component-scan base-package="com.hzbckj.spring" />

    <!-- 导入资源文件 -->
    <context:property-placeholder location="db.properties" />

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="user" value="${user}"></property>
        <property name="password" value="${password}"></property>
        <property name="jdbcUrl" value="${jdbcUrl}"></property>
        <property name="driverClass" value="${driverClass}"></property>
    </bean>

</beans>

这是spring配置文件

package com.hzbckj.spring.test;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**
 * Created by jackson on 2017/2/6.
 */
@Component
public class dataSourceTest {
    @Resource(name = "jdbcTemplate")
    private JdbcTemplate jdbcTemplate;

    public JdbcTemplate getJdbcTemplate() {
        return jdbcTemplate;
    }

    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    @Test
    public void testJdbc(){
//        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
//        JdbcTemplate jdbcTemplate = (JdbcTemplate)ctx.getBean("jdbcTemplate");
        String sql = "INSERT INTO user(name, balance) values('Jonn', 200)";
        jdbcTemplate.execute(sql);
    }

}

这是使用的地方
执行时jdbcTemplate一直报空

Answer 1

<context:component-scan base-package="com.hzbckj.spring" />
    这个放在最上面试试呢？
