SpringMVC 拦截器实现

SpringMvc实现拦截器方式一：

    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <bean class="xxx.UnLoginInteteceptor"></bean>
        </mvc:interceptor>
    </mvc:interceptors>

SpringMvc实现拦截器方式二：

    <!-- 拦截器 -->
    <bean class="org.springframework.web.servlet.handler.MappedInterceptor">
        <constructor-arg >
            <!-- 配置拦截请求配置 -->
            <array>
                <value>/**</value>
            </array>
        </constructor-arg>
        <constructor-arg>
            <!-- 配置拦截忽略配置 -->
            <array>
                <value>/login/**</value>
            </array>
        </constructor-arg>
        <constructor-arg ref="unLogininterceptor"></constructor-arg>
    </bean>
    <bean name="unLogininterceptor" class="xxx.UnLoginInteteceptor"></bean>

UnLoginInteteceptor.java文件内容

package xxx.interceptor;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.web.util.WebUtils;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

public class UnLoginIntereceptor implements HandlerInterceptor {

    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, 
            Object obj, Exception e) throws Exception {
    }

    public void postHandle(HttpServletRequest request, HttpServletResponse response, 
            Object obj, ModelAndView view) throws Exception {
    }

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, 
            Object obj) throws Exception {
        return true;
    }

}
