确保applicationContext.xml具有定义的bean'dataSource'。由于dataSource是一个构造函数arg，DAO应该传递一个构造函数arg而不是一个属性。注释一个构造函数方法并确保它接受一个dataSource。数据源通是同一个在applicationContext.xml定义：

<bean id="countryDao" class="com.crimetrack.jdbc.JdbcCountryDAO"> 
     <constructor-arg index="0" ref="dataSource"/> 
</bean> 

@Repository 
public class JdbcCountryDAO extends JdbcDaoSupport implements CountryDAO{ 

    private final Logger logger = Logger.getLogger(getClass()); 


    @Autowired 
    JdbcCountryDAO(DataSource dataSource){ 
     setDataSource(dataSource); 
    } 

    public List<Country> getCountryList() {.......................

谢谢，经过几个小时的谷歌搜索后，它解决了这个问题。 – Davor

很高兴知道这对你有帮助:) – devdar

的错误是，没有数据源或JdbcTemplate的是有线到JdbcCountryDao豆：

java.lang.IllegalArgumentException: 'dataSource' or 'jdbcTemplate' is required

但是你的XML配置说明您的数据源发送的，所以你确定这个错误在使用文件的发布版本时发生？

此外，没有必要声明@Autowired jdbcTemplate在继承JdbcDaoSupport的类中，因为超类已经为您提供了这个功能。

这是一个“让” – devdar

我是否需要创建一个DataSource类，然后瓶坯@Autowired – devdar

删除'@Autowired私人的JdbcTemplate JdbcTemplate的发生;'从JdbcCountryDao。 –
