我试图将名为“userVO”的bean映射到带有注释的安全控制器,当我通过xml配置映射它时它可以工作,但是当我使用注释时我不断收到以下错误
警告:/login.xhtml @22,37 value="#{securityController.userVO.vc_name}":目标无法访问,'userVO' 返回 null
我必须说 UserVO 在我也拥有的另一个项目中,并且它的依赖关系是用 maven 处理的
以下是我的 spring-beans 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-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<import resource="mapper-beans.xml" />
<bean name="userVO" id="userVO" class="rst.core.security.UserVO"
scope="session" />
<context:annotation-config />
<context:component-scan base-package="rst.core.security" />
<context:component-scan base-package="rst.controller" />
</beans>
以下是映射到 userVO 的控制器,但它不起作用:
@ManagedBean
@RequestScoped
@Controller
public class SecurityController {
public static Logger log;
private WebFacade webFacade;
@Autowired
private UserVO userVO;
public SecurityController() {
log = LoggerFactory.getLogger(this.getClass());
log.debug("Creating SecurityController.");
}
public String login() {
UserVO user= webFacade.validateUser(getUserVO()); // method to search the db
if (user!= null) {
return "accessGranted";
} else {
return "accessDenied";
}
}
//getters and setters....
}
这也是触发错误的登录屏幕:
