找不到 Bean 错误

Question

这是代码片段

@Component()
public class DbConn {
@Resource(name="vDataSource")
protected DataSource dataSource;
public  void doCall () {
SimpleJdbcCall jdbcCall = new SimpleJdbcCall(dataSource)
//          .withCatalogName(config.getPackageName())
.withProcedureName("TEST_PROC")
.withoutProcedureColumnMetaDataAccess();
}

这是我的主要课程

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring/" + "v-test.xml") ;
DbConn d1= context.getBean("dbConn",DbConn.class);

当我尝试运行 main 时，它会抛出一个错误： 没有定义名为"dbConn"的 bean

如何解决问题

我的应用程序上下文 v-test.xml 也在下面

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<property name="password" value="${jdbc.v.password}"/>
<property name="testOnBorrow" value="true" />
<property name="validationQuery" value="SELECT 1 FROM DUAL" />
</bean>
</beans>

尝试命名您的组件：

@Component("dbConn"(
