Spring @autowired无法注入

[小胖9040]

Web.xml中是不是也要添加参数
我试了一下直接获取prodcutService可以直接运行就像这样

这里没有service所在的包：

指定接口 指定实现 两个一起指定都试了 都没用

[quote=引用 9 楼 li4562258fj155 的回复:] [quote=引用 7 楼 xiakepan 的回复:] 你的ProductService有添加@Service么 just like this:

还是不行啊 [/quote] 这里没有service所在的包： [/quote] 试一下这种方法： 在ProductServiceImpl类上写@Service("productServiceImpl") 在ProductController3类中的ProductService属性上面写 @Autowired @Qualifier("productServiceImpl")

都试了 但是还是不管用啊 我都想放弃了

你的web.xml中配置的属性名 contextconfiglocation 应该是 springmvc.xml 这个xml是开启基于注解功能的，只需在里面配置 <!-- 该 BeanPostProcessor 将自动对标注 @Autowired 的 Bean 进行注入 --> <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/> 这趟@autowire才能生效呢

<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>

这是web.xml中的配置

这是springmvc.xml中的配置

15楼错误是你配置文件路径不对。 最上面的那个错误是你得指定 Qualifier 。因为你现在是多个，找不到对应的实现类，所以得配置上Qualifier 。

[scmod]

@Service("productService")加在实现类上 还有最开始实现类上没加@Service的时候你那样直接getBean出来不为null吗? 是不是自己在配置文件里面加了bean class="xx.xx.ProductServiceImpl" id="productService"了?spring配置文件貌似没发全

application.xml中添加开启扫描注解： <context:component-scan base-package="com.**.dao"/> <context:component-scan base-package="com.**.web"/>

都试了可是还是没用啊

[mtian2020]

看一下你的base-package的值有没有和你的controller和dao所在路径对应上

[小胖9040]

我用的是mapper应该不是这个问题吧

[licip]

autowire你是根据名字自动注入，还是根据类型自动注入，再加一属性指明吧。

[小胖9040]

@无法显示此用户 大神求助啊

[tony4geek]

路径不对啊。你看看 你看看 你spring 路径怎么配置的。 java calsspath*

[小胖9040]

@无法显示此用户 大神我没搞懂自己是哪错了 所以Web.xml中的配置没变 但是我把applicationContext.xml中的配置改了就可以运行了

红框内的东东是新加的以前没有 您知道是怎么回事吗？

[空心兜兜]

classpath这种写法……不一定兼容所有web容器

[小胖9040]

各位大神们我找到问题的所在了 是我的spring监听器出来问题Spring容器根本就没有加载 所以才会这样
但是现在我的监听器问题还是没解决 大家帮忙看看
web.xml配置

[tony4geek]

Could not open ServletContext resource [/sqlMapConfig.xml] 看看 sqlMapConfig 怎么配置的。/

[小胖9040]

sqlMapConfig.xml中的配置


我用new ClassPathXmlApplicationContext("applicationContext.xml");再getBean就可以正常运行

[Jacky【YL】]

查看实体BEEN 有没有加上注解
