在Spring Boot 3.1.5中，您可以使用以下步骤来创建安全过滤器链：

步骤1：创建一个自定义的安全过滤器类

import org.springframework.security.core.AuthenticationException
import org.springframework.security.web.AuthenticationEntryPoint
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter
import org.springframework.stereotype.Component
import javax.servlet.FilterChain
import javax.servlet.http.HttpServletRequest
import javax.servlet.http.HttpServletResponse

@Component
class CustomAuthenticationFilter : UsernamePasswordAuthenticationFilter() {

    override fun attemptAuthentication(request: HttpServletRequest, response: HttpServletResponse): Authentication {
        // 在这里处理身份验证逻辑
    }
    
    override fun successfulAuthentication(request: HttpServletRequest, response: HttpServletResponse, chain: FilterChain, authResult: Authentication) {
        // 在这里处理身份验证成功后的逻辑
    }
    
    override fun unsuccessfulAuthentication(request: HttpServletRequest, response: HttpServletResponse, failed: AuthenticationException) {
        // 在这里处理身份验证失败后的逻辑
    }
}

步骤2：创建一个自定义的身份验证入口点类

import org.springframework.security.core.AuthenticationException
import org.springframework.security.web.AuthenticationEntryPoint
import org.springframework.stereotype.Component
import javax.servlet.http.HttpServletRequest
import javax.servlet.http.HttpServletResponse

@Component
class CustomAuthenticationEntryPoint : AuthenticationEntryPoint {

    override fun commence(request: HttpServletRequest, response: HttpServletResponse, authException: AuthenticationException) {
        // 在这里处理身份验证入口点逻辑
    }
}

步骤3：配置安全过滤器链

import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.security.config.annotation.web.builders.HttpSecurity
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter

@Configuration
@EnableWebSecurity
class SecurityConfig : WebSecurityConfigurerAdapter() {

    override fun configure(http: HttpSecurity) {
        http
            .addFilterBefore(customAuthenticationFilter(), UsernamePasswordAuthenticationFilter::class.java)
            .exceptionHandling().authenticationEntryPoint(customAuthenticationEntryPoint())
            // 添加其他的安全配置
    }
    
    @Bean
    fun customAuthenticationFilter(): CustomAuthenticationFilter {
        return CustomAuthenticationFilter()
    }
    
    @Bean
    fun customAuthenticationEntryPoint(): CustomAuthenticationEntryPoint {
        return CustomAuthenticationEntryPoint()
    }
}

在上面的代码示例中，我们创建了一个自定义的安全过滤器CustomAuthenticationFilter来处理身份验证逻辑，一个自定义的身份验证入口点CustomAuthenticationEntryPoint来处理未经身份验证的请求。然后，在SecurityConfig类中，我们配置了安全过滤器链，并将自定义的过滤器和入口点添加到过滤器链中。

请根据您的实际需求修改上述代码示例中的逻辑。
