访问Web应用程序或命中url时未调用自定义Spring过滤器

Question

下面是我在网络上的配置。xml和我有一个JwtFilter，但当调用rest URL时，它无法访问。

网状物xml

<web-app
<display-name>Portal Web</display-name>

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/mvc-dispatcher-servlet-spring-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>jwtFilter</filter-name>
    <filter-class>com.pingle.lola.authentication.JwtFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>jwtFilter</filter-name>
    <url-pattern>/portal/lola/*</url-pattern>
</filter-mapping>

这是我的JwtFilter

public class JwtFilter extends GenericFilterBean {

@Override
public void doFilter(final ServletRequest req,
                     final ServletResponse res,
                     final FilterChain chain) throws IOException, ServletException {
    final HttpServletRequest request = (HttpServletRequest) req;
    System.out.println("came here");
    final String authHeader = request.getHeader("Authorization");
    System.out.println("came here - " + authHeader);
    if (authHeader == null || !authHeader.startsWith("Bearer ")) {
        System.out.println("should throw");
        throw new ServletException("Missing or invalid Authorization header.");
    }

    final String token = authHeader.substring(7); // The part after "Bearer "
    System.out.println("came here" + token);

    try {
        final Claims claims = Jwts.parser().setSigningKey("secretkey")
            .parseClaimsJws(token).getBody();
        request.setAttribute("claims", claims);
    }
    catch (final SignatureException e) {
        throw new ServletException("Invalid token.");
    }

    chain.doFilter(req, res);
}

}

我有基本的RestAPI混淆的控制器。我正在尝试检查是否有任何URL像localhost:8080/portal/lola/getData一样被击中...它应该转到JwtFilter并检查请求标头中的身份验证令牌，如果有效，则将其传递给控制器，否则会抛出错误消息。逻辑编写正确，但未调用过滤器，当我点击上面的URL时，它会直接进入控制器而不会到达过滤器。

我的Spring配置。xml

<context:component-scan base-package="com.pingle.lola.controller"/>
<mvc:annotation-driven/>

//不知道为什么我在它没有映射到任何控制器时创建了它：(

    <mvc:default-servlet-handler/>

似乎/port是应用程序上下文的名称。过滤器url模式不应包含上下文名称。这意味着，过滤器url模式应该是/lola/*而没有/port。尝试将过滤器映射更改为：

<filter-mapping>
    <filter-name>jwtFilter</filter-name>
    <url-pattern>/lola/*</url-pattern>
</filter-mapping>
