在Spring Boot中配置Filter有以下几种方法:
@WebFilter
注解,并指定urlPatterns来配置Filter的拦截路径。示例代码如下:@WebFilter(urlPatterns = "/api/*")
public class MyFilter implements Filter {
// Filter的具体实现代码
}
@Configuration
public class FilterConfig {
@Bean
public FilterRegistrationBean<MyFilter> myFilter() {
FilterRegistrationBean<MyFilter> registration = new FilterRegistrationBean<>();
registration.setFilter(new MyFilter());
registration.addUrlPatterns("/api/*");
return registration;
}
}
@Configuration
public class FilterConfig {
@Bean
public ServletRegistrationBean<MyFilter> myFilter() {
ServletRegistrationBean<MyFilter> registration = new ServletRegistrationBean<>();
registration.setFilter(new MyFilter());
registration.addUrlPatterns("/api/*");
return registration;
}
}
以上三种方法都可以实现对Filter的配置,具体选择哪种方法取决于具体的需求和场景。
