在springboot中注入FilterRegistrationBean不生效的原因

 
    @Bean
    public FilterRegistrationBean filterRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new EncryptionFilter());
        registration.addUrlPatterns("
    @Bean
    public FilterRegistrationBean filterRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new SqlInjectManagerFilter());
        registration.addUrlPatterns("
    @Bean(name = "encryptionFilter")
    public FilterRegistrationBean filterRegistration() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new EncryptionFilter());
        registration.addUrlPatterns("

        registration.addUrlPatterns("/*");
        registration.setName("sqlInjectManagerFilter");
        registration.setOrder(2);
        return registration;
