自定义过滤器类： - 

package com.app.api.filter;

import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.MediaType;

import com.fasterxml.jackson.databind.ObjectMapper;

@WebFilter("/*")
public class AuthenticationFilter implements Filter {
    private static final Logger LOGGER = LoggerFactory.getLogger(AuthenticationFilter.class);

    public AuthenticationFilter() {
        System.out.println("Authentication - default filter !");
    }

    public void destroy() {
        System.out.println("Authentication - destroy !");
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        LOGGER.debug("Request authentication!");
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        String uri = httpRequest.getRequestURI();
        if(uri.equals("/app-api/login") || uri.equals("/app-api/logout")) {
            chain.doFilter(request, response);
            return;
        }

        HttpSession session = httpRequest.getSession(false);
        if(session == null || session.getAttribute("user") == null) {
            writeInvalidCredentialResponse((HttpServletResponse) response);
        } else {
            chain.doFilter(request, response);
        }
    }

    private void writeInvalidCredentialResponse(HttpServletResponse response) throws IOException {
        Map<String, String> errorResponse = new HashMap<String, String>();
        errorResponse.put("message", "Please login with right credentials!");
        ObjectMapper mapper = new ObjectMapper();
        String responseMessage = mapper.writeValueAsString(errorResponse);

    }

    public void init(FilterConfig fConfig) throws ServletException {
        System.out.println("Authentication - init !");
    }

}
  

项目层次结构： -

     
    

A - 父maven模块

         

B - RESTful webservices子模块（包含 - /WEB-INF/web.xml,/WEB-INF/dispatcher-servlet.xml）

         

C - 持久层子模块（包含 - /resources/applicationContext.xml,/resources/persistence.xml）

  

请帮我解决这个问题，使我的弹簧上下文运行起来（ui - webservices和persistence） 非常感谢提前！

尝试删除@WebFilter并确保您的init方法覆盖，因为我们无法在提供的代码中看到它。

答案 1 :(得分：0)

让我们看看例外：

java.lang.ClassNotFoundException: com.adobe.ssp.api.filter.AuthenticationFilter

您的类路径出现问题，找不到类“ com.adobe.ssp.api.filter.AuthenticationFilter ”。请确保此课程包含在： YOUR_APP \ WEB-INF \ classes 或 YOUR_APP \ WEB-INF \ lib
