Spring注解@Inject不起作用

我有代码@Inject在一个类中可用，但在另一类中不可用. 这是我的代码:

I have the code @Inject works in one class but not in other. Here's my code:

• context.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="www.springframework/schema/beans" xmlns:xsi="www.w3/2001/XMLSchema-instance" xmlns:context="www.springframework/schema/context" xsi:schemaLocation=" www.springframework/schema/beans www.springframework/schema/beans/spring-beans.xsd www.springframework/schema/context www.springframework/schema/context/spring-context.xsd "> <bean id="multipartResolver" class="org.springframework.web.multipartmons.CommonsMultipartResolver"></bean> <context:component-scan base-package="com.myfashions.services"/> <context:component-scan base-package="com.myfashions.dao"/> </beans>

• SellerRetriever.java
public class SellerRetriever { @Inject UserDAO userDAO; ... ... }

UserDAO类存在于com.myfashions.dao软件包中. @Inject在Seller.java中不起作用.有什么原因吗?

UserDAO class is present in com.myfashions.dao package. @Inject is not working in Seller.java. Any reason why?

推荐答案

我发现了我的错误，我发布了此错误，因为万一有人遇到同样的问题.我使用新的运算符创建了SellerRetriver对象.如果使用新的运算符调用该特定类，则注入将不起作用.

I found my mistake, I'm posting this because in case anyone has the same problem. I used new operator to create an SellerRetriver object. Inject won't work if new operator is used to call that particular class.
