Question

在我的自定义用户详细信息服务中，我的变量“aUserService”即使已经注释也不会自动连接。尝试了很多方法，但仍然失败，值为null。

我正在遵循krams教程。 http://krams915.blogspot.sg/2012/01/spring-security-31-implement_1244.html

这是我的项目https://skydrive.live.com/#cid=837EF1FA9A4C06AE&id=837EF1FA9A4C06AE%21130，环境：netbeans 7.2，maven，tomcat 7.0.39，postgresql 9.2，db sql在项目中。在META-INF / context.xml

定义的数据库池

这是我的的web.xml

Answer 1

解决的问题。造成它的原因有两个。

从安全xml中删除<debug/> https://jira.springsource.org/browse/SEC-1885
在spring-servlet.xml中放入org.springframework.web.servlet.view.InternalResourceViewResolver类（之前我放入应用程序上下文xml）。

现在：

我的web.xml

......
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
......

我的spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
    <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

Answer 2

您没有在我的root-context.xml中定义UserService aUserService。您必须将其定义为

  <beans:bean id="aUserService" class=" UserService implementation classname">

或

在UserService实现类中添加@Service注释。这样就可以了。

Answer 3

根据您的初始设置，以下内容应该有效：

由于您在@Service("jpaUserService")（http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/stereotype/Service.html）中指定了bean创建的名称，因此通过此名称引用从注释扫描创建的Bean的名称。所以你可以用这个名字来引用它。为此，请执行以下操作：

@Autowired
@Qualifier("jpaUserService"")
private UserService aUserService;

根据以下https://stackoverflow.com/a/634754/2319179

，无需使用getter和setter

Answer 4

问题：自动装配失败是因为Spring默认使用JDK-Dynamic代理创建代理（它创建一个实现目标类接口的代理）。另一方面，基于CGLIB的代理是目标类的子类。请参阅：JDK动态代理和CGLib之间有什么区别？要启用基于CGLIB的代理，请使用

注释其中一个@Configuration类

@EnableAspectJAutoProxy(proxyTargetClass=true):
@Configuration
@EnableAspectJAutoProxy(proxyTargetClass=true)
public class AppConfig

{ ... } - 请参阅：http://www.mzan.com/article/35525838-spring-security-config-autowiring-custom-userdetailsservice-bean.shtml#sthash.S3YwrKyC.dpuf

并添加： org.aspectj aspectjweaver 1.8.9
