@Component
@ServletComponentScan
@WebFilter(urlPatterns = "/*",filterName = "loginFilter")
public class LoginFilter implements Filter{
}1、@Component 这个注解的目的是将LoginFilter交给容器来处理。也就是让LoginFilter起作用
public class LoginFilter implements Filter{
}或继承GenericFilterBean
public class LoginFilter extends GenericFilterBean{
}@SpringBootApplication
public class SpringRestApplication {
public static void main(String[] args) {
SpringApplication.run(SpringRestApplication.class, args);
}
@Bean
public FilterRegistrationBean filterRegistrationBean() {
FilterRegistrationBean registrationBean = new FilterRegistrationBean();
HTTPBasicAuthorizeAttribute httpBasicFilter = new HTTPBasicAuthorizeAttribute();
registrationBean.setFilter(httpBasicFilter);
List<String> urlPatterns = new ArrayList<String>();
urlPatterns.add("/user/*");
registrationBean.setUrlPatterns(urlPatterns);
return registrationBean;
}
