我看到Vasily Komarov的答案。这里有一个类似的方法，但是使用抽象的HandlerInterceptorAdapter类而不是使用HandlerInterceptor。

这里有一个例子……

@Component
public class CustomInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
        throws Exception {
    }
}

@Configuration
public class InterceptorConfig extends WebMvcConfigurerAdapter {

    @Autowired
    private CustomInterceptor customInterceptor ;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(customInterceptor );
    }

}

首先，将@ServletComponentScan添加到SpringBootApplication类中。

@ServletComponentScan
public class Application {

其次，创建一个过滤器文件，扩展filter或第三方过滤器类，并像这样添加@WebFilter到这个文件:

@Order(1) //optional
@WebFilter(filterName = "XXXFilter", urlPatterns = "/*",
    dispatcherTypes = {DispatcherType.REQUEST, DispatcherType.FORWARD},
    initParams = {@WebInitParam(name = "confPath", value = "classpath:/xxx.xml")})
public class XXXFilter extends Filter{

我看到Vasily Komarov的答案。这里有一个类似的方法，但是使用抽象的HandlerInterceptorAdapter类而不是使用HandlerInterceptor。

这里有一个例子……

@Component
public class CustomInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
        throws Exception {
    }
}

@Configuration
public class InterceptorConfig extends WebMvcConfigurerAdapter {

    @Autowired
    private CustomInterceptor customInterceptor ;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(customInterceptor );
    }

}

没有特殊的注释来表示servlet筛选器。您只需声明一个Filter类型的@Bean(或FilterRegistrationBean)。在Boot自己的EndpointWebMvcAutoConfiguration中有一个例子(为所有响应添加自定义头);

如果你只声明一个过滤器，它将被应用到所有的请求。如果您还添加了一个FilterRegistrationBean，您可以另外指定要应用的单个servlet和url模式。

注意:

从Spring Boot 1.4开始，FilterRegistrationBean不再弃用，而是简单地将包从org.springframework. Boot .context. embedd.filterregistrationbean移动到org.springframework.boot.web.servlet.FilterRegistrationBean

如果您想要设置一个第三方过滤器，您可以使用FilterRegistrationBean。

例如，等价的web.xml:

<filter>
     <filter-name>SomeFilter</filter-name>
        <filter-class>com.somecompany.SomeFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>SomeFilter</filter-name>
    <url-pattern>/url/*</url-pattern>
    <init-param>
        <param-name>paramName</param-name>
        <param-value>paramValue</param-value>
    </init-param>
</filter-mapping>

这将是@Configuration文件中的两个bean:

@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;
}

public Filter someFilter() {
    return new SomeFilter();
}

以上是用Spring Boot 1.2.3测试的。

如果您使用Spring Boot + Spring Security，则可以在安全配置中执行此操作。

在下面的示例中，我在UsernamePasswordAuthenticationFilter之前添加了一个自定义过滤器(请参阅所有默认的Spring安全过滤器及其顺序)。

@EnableWebSecurity
class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired FilterDependency filterDependency;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .addFilterBefore(
                new MyFilter(filterDependency),
                UsernamePasswordAuthenticationFilter.class);
    }
}

还有筛选器类

class MyFilter extends OncePerRequestFilter  {
    private final FilterDependency filterDependency;

    public MyFilter(FilterDependency filterDependency) {
        this.filterDependency = filterDependency;
    }

    @Override
    protected void doFilterInternal(HttpServletRequest request,
        HttpServletResponse response,
        FilterChain filterChain)
        throws ServletException, IOException {

        // Filter
        filterChain.doFilter(request, response);
    }
}
