@Autowired 注释不起作用
我正在尝试像这样测试 Autowire 选项：
@ContextConfiguration(locations = { "classpath:applnContext.xml" })
public class Foo {
@Autowired
private Bar bar;
public Bar getBar() {
return bar;
}
public void setBar(final Bar bar) {
this.bar = bar;
}
public static void main(final String[] args) {
final Foo f = new Foo();
System.out.println(f.getBar());
}
}
和配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<bean id="bar" class="entity.Bar"></bean>
<context:annotation-config />
</beans>
但是 Bar 对象没有被注入。我在这里错过了什么或者做错了什么吗？
请注意，我使用类上的注释来指定 applicationContext 文件。
I'm trying to test the Autowire option like this:
@ContextConfiguration(locations = { "classpath:applnContext.xml" })
public class Foo {
@Autowired
private Bar bar;
public Bar getBar() {
return bar;
}
public void setBar(final Bar bar) {
this.bar = bar;
}
public static void main(final String[] args) {
final Foo f = new Foo();
System.out.println(f.getBar());
}
}
and the config file :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<bean id="bar" class="entity.Bar"></bean>
<context:annotation-config />
</beans>
But the Bar object is not getting injected. Am I missing anything here or doing something wrong?
Note that I'm specifying the applicationContext file using annotation on the class.

如果这是一个单元测试，就像看起来一样，请
在您的
applicationContext.xml中添加 And 不要忘记这一点（尽管在这种情况下这不是问题）If this is a unit-test, as it seems, add
And in your
applicationContext.xmldon't forget this (although in this case it is not the problem)@ContextConfiguration 属性是 org.springframework.test 包的一部分，因此不会以您尝试使用它的方式工作。有关更多详细信息，请参阅 Spring 论坛上的这篇文章。
The @ContextConfiguration attribute is part of the
org.springframework.testpackage, so isn't going to work in the manner you've attempted to use it. See this post on the Spring forums for more details.
