Spring Boot添加自定义Filter

第一步：编写自己的Filter

public class MyFilter implements Filter {

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException {  
        //do you works
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }
    @Override
    public void destroy() {
    }  
}

第二步：在启动主类引入编写的Filter

    @Bean
    public FilterRegistrationBean MyFilterRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new MyFilter());
        registration.addUrlPatterns("/*");
        registration.addInitParameter("paramName", "paramValue");
        registration.setName("MyFilter");
        registration.setOrder(1);
        return registration;
    }
