如何基于 URL 模式应用 Spring Boot 过滤器?

2022-01-13 00:00:00 annotations filter spring java spring-boot

我创建了一个 Spring Boot 过滤器 - 使用 @Component 注释实现 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 Framework 自动识别，适用于所有 REST API.我希望此过滤器仅适用于某个 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 初始化程序 - 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.

什么是让它工作的正确方法?

What would be the correct way to get it working?

推荐答案

你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();
}
