我有一个使用注释@Autowired的项目。我有一些端点,服务和存储库。除此之外,我想创建一个javax.servlet.Filter来在它前面放置一个过滤器。一切都有效,除了过滤器。
我的代码是这样的:
(滤波器)
package com.mysportslife.web.auth;
<import>
@Provider
@Component
public class TokenFilter implements Filter {
@Autowired
private UserService userService;
@Autowired
private TokenService tokenService;
....
....
(TokenService)
package com.mysportslife.web.auth;
<import>
@Service
public class TokenService {
@Autowired
private UserService userService;
....
....
(UserService)
package com.mysportslife.services;
<import>
@Service
public class UserService {
@Autowired
private UserRepository userRepository;
....
....
(web.xml)中
<web-app xmlns:javaee="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name>mysportslife</display-name>
<description>Backend for MySportslife</description>
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.mysportslife.web</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-servlet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<filter>
<filter-name>TokenFilter</filter-name>
<filter-class>com.mysportslife.web.auth.TokenFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>TokenFilter</filter-name>
<url-pattern>/rest/*</url-pattern>
</filter-mapping>
<!-- Algemene configuratie -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:ApplicationContext.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
(applicationContext.xml中)
<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-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:component-scan base-package="com.mysportslife"/>
<import resource="ApplicationContext-persistence.xml"/>
</beans>
任何人都知道为什么filterer中的userservice和tokenservice为空?
如果需要更多信息,请告诉我。提前谢谢!

这是因为该对象没有通过Spring初始化。为了让你的bean自动为你的bean自动化(超级简单的版本):
在您的情况下,第二个条件未得到满足。
这里有更详细的解释:

答案确实是DelegatingFilterProxy。 (感谢Gergely Basco)..
我在web.xml中的过滤器看起来像这样,它可以工作:
<filter>
<filter-name>tokenFilter</filter-name>
<filter-class> org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>tokenFilter</filter-name>
<url-pattern>/rest/*</url-pattern>
</filter-mapping>
