在服务器启动期间出现以下错误。
org.springframework.beans.factory.beancreationexception:创建名为“kuttyjavacontroller”的bean时出错:自动连线依赖项的注入失败;嵌套异常为org.springframework.beans.factory.beancreationexception:could not autowire字段:private org.springframework.jdbc.core.jdbctemplate com.service.kuttyjavacontroller.jdbcoriensb2c;嵌套的异常为org.springframework.beans.factory.nosuchbeandefinitionexception:找不到符合依赖关系类型[org.springframework.jdbc.core.jdbctemplate]的合格bean:至少需要1个符合此依赖关系的autowire候选bean。依赖项注解:{@org.springframework.beans.factory.annotation.autowired(required=true)}

你的豆子名字不匹配。例如,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>

然而,你称之为:

//Nstore B2b
private JdbcTemplate jdbcnstoreb2b;

这应该是(当然,在 Camel 的情况下也是这样):

//Nstore B2b
private JdbcTemplate nstoreb2btemplate;
