我在我的xml中使用了beans:profiles
,如下所示:
<beans profile="dev">
<bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.internal.url}" />
<property name="username" value="${jdbc.internal.username}" />
</bean>
</beans>
我在web.xml中设置了spring.active.profiles
:
<servlet>
<servlet-name>myapp</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/myapp-servlet.xml</param-value>
</init-param>
<init-param>
<param-name>spring.profiles.active</param-name>
<param-value>dev</param-value>
</init-param>
</servlet>
我的代码结构是这样的:
//controller
@Controller
public class MyController {
@Autowired
private MyService myService;
....
}
//service implementation
@Service("myservice")
public class MyServiceImpl implements MyService {
@Autowired
DBService dbService;
}
//db service
@Service("dbservice)
public class DBServiceImpl implements DbService {
@Autowired
public void setDataSource (Datasource ds) {
this.jdbcTemplate = new JdbcTemplate(ds);
}
}
错误:
创建名为'myController'的bean时出错:注入 自动连接依赖失败;嵌套异常是 org.springframework.beans.factory.BeanCreationException:不能 autowire字段:私有MyService MyController.myService; 嵌套异常是 org.springframework.beans.factory.BeanCreationException:

答案 0 :(得分:1)
我猜你在DispatcherServlet上下文中使用了profile,而DataSource可能位于根应用程序上下文中。

更新:尝试使用context-params(取自here):
<context-param>
<param-name>spring.profiles.active</param-name>
<param-value>dev</param-value>
</context-param>
