报错说
Could not autowire field: private org.springframework.jdbc.core.JdbcOperations com.tjpme.ecif.etl.dao.JdbcTemplateHelper.jdbcTemplate; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.jdbc.core.JdbcOperations] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 意思是没有org.springframework.jdbc.core.JdbcOperations]这个类型，你有声明这个bean吗？ @Autowired按byType自动注入！ |
|
JdbcOperations spring 里面的也要声明吗bean吗 |
|
JdbcOperations 你不声明的话，spring没办法找到的！@Autowired会在已经声明过的bean中查找和要注入类型想匹配的bean，必须有一个，且只能有一个类型匹配的，多了，少都会报错！ |

<bean id=”jdbcTemplate”
class=”org.springframework.jdbc.core.JdbcTemplate”> <property name=”dataSource”> <ref bean=”dataSource” /> </property> </bean> gaoding了 谢谢！ |
