在spring data rest中，无法启动bean 'documentationPluginsBootstrapper'。
在spring data rest中，无法启动bean 'documentationPluginsBootstrapper'。
我正在使用Spring Data Rest来开发我的应用程序。
当我在仓库中添加以下方法时，我遇到了以下错误，并且应用程序无法启动：
方法：
@Modifying
@Transactional
@Query("from employee as ft where ft.company.id = ?1")
void deleteAllEmployeeCompany(
@Param("companyId") @RequestParam("companyId") int companyId);
错误：
org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

在使用springfox-swagger2和springfox-swagger-ui版本（3.0.0）以及spring-boot版本（2.6.2）时，我遇到了同样的问题。
解决这个问题的方法是在application.properties或application.yml中添加pathmatcher配置。
对于application.properties：
spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER
对于application.yml：
spring:
mvc:
pathmatch:
matching-strategy: ant_path_matcher
这样做可以解决问题吗？
这个配置是用来做什么的？
对我来说，这个方法在springfox-swagger-ui版本（3.0.0）和spring-boot版本（2.6.2）上没有起作用。我将spring-boot版本降级到了2.5.8，问题得到了解决，不需要在我的application.properties中添加spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER。
这个解决方法对我有效：github.com/springfox/springfox/issues/…
在使用spring boot 2.6.3时对我有效。
如果你使用了spring actuator，这个方法将不起作用。
这个方法对我也有效，我升级到了spring boot 2.6。
我尝试了多种解决方法，但最终通过以上方法解决了问题，我的spring版本是2.6.4，我还使用了spring actuator springfox-swagger2 - 3.0.0 springfox-boot-starter - 3.0.0 springfox-swagger-ui - 3.0.0。
这个方法对我在spring版本2.6.7和所有springfox依赖版本3.0.0上有效。
在我使用的swagger版本：'2.6.0'上解决了这个问题。
对我解决了问题（springfox-swagger2版本3.0.0和spring-boot版本2.7.4）。
只有更改application.properties对我有效。
在使用Spring Data Rest时出现了"Failed to start bean 'documentationPluginsBootstrapper'"的错误。出现这个错误的原因是因为Spring默认使用了mvcmatchers，而Swagger使用了antmatchers，导致冲突。解决这个问题的方法有以下几种：
A. 修改Spring使用antmatchers：
在application.properties文件中添加以下配置：
spring.mvc.pathmatch.matching-strategy = ANT_PATH_MATCHER
B. 在Spring中启用mvcmatchers，并为Swagger创建一个配置文件：
1. 在任意位置创建一个Swagger配置文件，命名为SwaggersConfigs。
2. 在该文件中添加以下注解：
public class SwaggersConfigs {
}
C. 在Spring应用程序的主类上启用mvcmatchers：
在Spring Boot应用程序的主类上添加以下注解：
public class SwaggerDemoApplication {
public static void main(String[] args) {
SpringApplication.run(SwaggerDemoApplication.class, args);
}
}
D. 使用其他版本的Spring和Swagger。
以上解决方法中，D选项由一位“传奇”提供。
通过以上方法，可以解决"Failed to start bean 'documentationPluginsBootstrapper'"错误。
这个问题的出现原因是由于Spring Fox 3.0.0不支持Spring MVC的新默认路径匹配策略PathPattern Based Path Matching Strategy，这个新策略是从spring-boot 2.6.0开始的。解决方法有以下几种：
1. 将spring-boot版本降级到2.6.0以下。不推荐这种方法，因为旧版本的spring boot / spring framework存在严重的安全问题。
2. 在yml文件中将PathPattern匹配改回AntPatternMatching。可以参考上述链接中提到的方法。
3. 推荐将项目中的SpringFox完全移除，并替换为维护良好的springdoc-openapi库。springdoc的文档中有关于从SpringFox迁移的说明，迁移过程非常简单，而且可以完全摆脱SpringFox引起的问题。
个人认为第三种方法是最好的解决方案。依赖一个几乎两年没有更新的项目是不明智的选择。截至目前，SpringFox自2020年10月以来没有进行任何提交。
降级spring-boot可能会导致旧版本的log4j存在严重的JNDI调用漏洞，请小心使用。
每当我看到"降级"这个词，我都感到不安。
