Question

springmvc的拦截器，怎么设置不拦截的url

Answer 1

在xml里配置拦截器的地方设置一下exclude-mapping：

<mvc:interceptors>
  <mvc:interceptor>
    <mvc:mapping path="/project/**" /> <!--拦截-->
    <mvc:exclude-mapping path="/project/api/**" /> <!--忽略-->
    <bean class="xx.xx.XXXInterceptor" /> <!--你的拦截器-->
  </mvc:interceptor>
</mvc:interceptors>

如果你用SpringBoot，可以直接代码：

@Override
public void addInterceptors(InterceptorRegistry registry) {
  registry.addInterceptor(new XXXInterceptor()).addPathPatterns("/**").excludePathPatterns("/api/**");
  super.addInterceptors(registry);
}

Answer 2

<!-- 默认首页 -->
<mvc:view-controller path="/" view-name="redirect:/loginpage" />

<!-- 拦截器 -->
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**"/>
<mvc:exclude-mapping path="/loginpage/**"/>
<bean class="com.me.common.LoginInterceptor" />
</mvc:interceptor>
</mvc:interceptors>

<mvc:exclude-mapping path="/loginpage/**"/>

------------------改成----->

<mvc:exclude-mapping path="/"/>
<mvc:exclude-mapping path="/loginpage/**"/>

估计是你访问"/"时就到了拦截器
