答案 0 :(得分：6)
确保applicationContext.xml已定义bean“dataSource”。 DAO应该传递构造函数arg而不是属性，因为dataSource是构造函数arg。注释构造函数方法并确保它接受dataSource。 dataSource传递与applicationContext.xml中定义的相同：
<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() {.......................
答案 1 :(得分：1)
错误是没有dataSource或jdbcTemplate连接到JdbcCountryDao bean：
java.lang.IllegalArgumentException：'dataSource'或'jdbcTemplate'是必需的
但是，您的XML配置显示您已发送dataSource，因此您确定在使用文件的发布版本时会发生此错误吗？
此外，没有必要在扩展@Autowired jdbcTemplate的类中声明JdbcDaoSupport，因为超类已经为您提供了这个。{/ p>
