或者dao层直接继承JdbcTemplate类

0 回复 有任何疑惑可以回复我~

* JdbcDaoSupport类中有JdbcTemplate属性 

 * 而且该类没有无参的构造方法 ,因此当创建JdbcDaoSupport对象时,只能利用有参数的构造方法

 * 所以首先应该位属性赋值

我是用Maven创建的一个工程,然后在pom.xml文件中导入的jar包依赖,管理这些jar包,pom也没有出现红叉

增加的JdbcTemplate这个类的配置:

<!-- 配置jdbcTemplate -->

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">

  <constructor-arg ref="dataSource" />

</bean>

后来我在Spring配置文件中增加了JdbcTemplate的配置,将dataSource作为属性值注入进去,然后在dao源代码中配置了:@Resource的一个方法,调用父类的setJdbcTemplate方法,最后能够成功运行,但是我还是不明白为什么直接配置dataSource属性不行呢,难道是某个jar包的版本不匹配?

0 回复 有任何疑惑可以回复我~

我特意查看了源代码文件,发现JdbcDaoSupport这个类的代码基本上一致,按理说应该能注入成功,获得一个JdbcTemplate对象,但是后台报错推断出JdbcTemplate这个对象没有创建成功。
