如何解决Springboot @WebFilter拦截器未生效的问题?针对这个问题,这篇文章详细介绍了相对应的分析和解答,希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

解决方法
在springboot启动类上添加
@ServletComponentScan(basePackages = “full.package.path”)
路径替换为@WebFilter所在包
补充知识:在spring boot中使用@WebFilter配置filter(包括排除URL)
我就废话不多说了,大家还是直接看代码吧~
@WebFilter(urlPatterns = "/*")
@Order(value = 1)
public class TestFilter implements Filter {
private static final Set ALLOWED_PATHS = Collections.unmodifiableSet(new HashSet<>(
Arrays.asList("/main/excludefilter", "/login", "/logout", "/register")));
@Override
public void init(FilterConfig filterConfig) throws ServletException {
System.out.println("init-----------filter");
}
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
String path = request.getRequestURI().substring(request.getContextPath().length()).replaceAll("[/]+$", "");
boolean allowedPath = ALLOWED_PATHS.contains(path);
if (allowedPath) {
System.out.println("这里是不需要处理的url进入的方法");
chain.doFilter(req, res);
}
else {
System.out.println("这里是需要处理的url进入的方法");
}
}
@Override
public void destroy() {
System.out.println("destroy----------filter");
}
}
