我有springmvc和angularjs应用程序启动并运行。 在Springmvc我有一个名为userSessionBean的bean。 现在我正在添加一个拦截器,以弹簧mvc和它的前handel方法,我试图访问userSessionBean。Spring拦截器依赖注入
我的问题是“我可以注入userSessionBean内拦截”
/**
*
*/
package com.loginLite.remote.authentication.interceptors;
import java.util.Random;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import com.remote.authentication.model.UserSessionBean;
/**
* @author jamju02
*
*/
public class AuthenticationInteceptor implements HandlerInterceptor {
@Autowired
private UserSessionBean userSessionBean = null;
/**
* @return the userSessionBean
*/
public UserSessionBean getUserSessionBean() {
return userSessionBean;
}
/**
* @param userSessionBean the userSessionBean to set
*/
public void setUserSessionBean(UserSessionBean userSessionBean) {
userSessionBean = userSessionBean;
}
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
System.out.println("Pre-handle");
return true;
}
@Override
public void postHandle(HttpServletRequest request,
HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
Random rnd = new Random();
int tokenNumber = 100000 + rnd.nextInt(900000);
userSessionBean.setAuthTokenNumber(String.valueOf(tokenNumber));
response.addHeader("AUTH_TOKEN",userSessionBean.getAuthTokenNumber());
System.out.println("Post-handle");
}
@Override
public void afterCompletion(HttpServletRequest request,
HttpServletResponse response, Object handler, Exception ex)
throws Exception {
System.out.println("After completion handle");
}
}
我的分发程序Servlet
<mvc:interceptors>
<bean class="com.paychex.loginLite.remote.authentication.interceptors.AuthenticationInteceptor">
<property name="userSessionBean" ref="userSessionBean"></property>
</bean>
</mvc:interceptors>
<bean id="userSessionBean"
class="com.paychex.loginLite.remote.authentication.model.UserSessionBean"
scope="session">
<aop:scoped-proxy />
</bean>
你试过了吗? – zeroflagL
是的,我尝试了上面提到的代码,userSessionBean对象为null, – user1834664
你的配置是什么样的? – zeroflagL
