如何根据 URL 模式应用 Spring Boot 过滤器? [英] How to apply spring boot filter based on URL pattern?
问题描述
我创建了一个 Spring Boot 过滤器 - 使用 @Component
注释实现了 GenericFilterBean
.
I have created a spring boot filter - implements GenericFilterBean
with @Component
annotation.
@Component
public class MyAuthenticationFilter extends GenericFilterBean {
...
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
...
}
}
过滤器由 Spring Boot 框架自动识别,适用于所有 REST API.我希望此过滤器仅应用于某个 URL 路径,例如 /api/secure/*
但我找不到正确的方法.我试过 @WebFilter
但没有用.我没有使用 XML 配置或 servlet 初始值设定项 - 只是注释.
The filter is automatically identified by the Spring Boot Framework and works fine for all of the REST API. I want this filter to apply only on a certain URL path, such as /api/secure/*
but I can't find the right way.
I tried @WebFilter
but it didn't work.
I'm not using XML configuration or servlet initializer - just the annotations.
让它工作的正确方法是什么?
What would be the correct way to get it working?
推荐答案
您可以像这样添加过滤器:
You can add a filter like this:
@Bean
public FilterRegistrationBean someFilterRegistration() {
FilterRegistrationBean registration = new FilterRegistrationBean();
registration.setFilter(someFilter());
registration.addUrlPatterns("/url/*");
registration.addInitParameter("paramName", "paramValue");
registration.setName("someFilter");
registration.setOrder(1);
return registration;
}
@Bean(name = "someFilter")
public Filter someFilter() {
return new SomeFilter();
}
