Answer 1

你的豆子的名字不匹配。例如,您定义了以下内容：

<bean id="nstoreb2btemplate" name="nstoreb2btemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="nstoreb2b"></property>
</bean>

但是，您使用以下方式调用它：

//Nstore B2b
private JdbcTemplate jdbcnstoreb2b;

这应该是（当然也是在骆驼的情况下）：

//Nstore B2b
private JdbcTemplate nstoreb2btemplate;
