java - 无法在 Spring Security 中解析符号“SamlServerConfiguration”

Question

我有一个 spring-boot 项目，我正在尝试使用spring-boot-starter-security(v2.1.4.RELEASE) 和spring-security-saml2-core(v1.0.9.RELEASE) 包创建 SAML2 身份提供者 (IdP)。我基本上是在尝试自定义和构建https://github.com/fhanik/springone2018/blob/master/demo/saml-idp中的代码。但是，当我构建代码时，出现以下错误：

包 org.springframework.security.saml.provider 不存在

找不到符号符号：类 SamlServerConfiguration

我相信我已经包含了参考实现中提到的所有必需的包，所以我不确定为什么会出现这个错误。

以下是我项目中的文件。

AppConfig.java（包含错误的文件）：

package com.example.saml.identityprovider;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.saml.provider.SamlServerConfiguration; // error: package does not exist

@ConfigurationProperties(prefix = "spring.security.saml2")
@Configuration
public class AppConfig extends SamlServerConfiguration {  // error: symbol not found
}

Application.java（包含main的文件）：

package com.example.saml.identityprovider;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
public class Application {
    private static final Logger logger = LoggerFactory.getLogger(Application.class);

    /**
     * Returns the homepage message.
     *
     * @return String message
     */
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String getHome() {
        logger.info("Received request for '/' endpoint");
        return "This is a SAML identity provider.";
    }

    /**
     * Provides SPs to select from.
     *
     * @return String
     */
    @RequestMapping("/selectsp")
    public String selectProvider() {
        logger.info("Sample IdP application - Select an SP");
        return "redirect:/saml/idp/select";
    }

    /**
     * Main method.
     *
     * @param args Command-line args
     */
    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }
}

如果有人能指出我可能会错过什么，我将不胜感激。提前致谢！
