集成springfox-swagger3 报错

java.lang.NoSuchMethodError: org.springframework.plugin.core.PluginRegistry.getPluginFor(Ljava/lang/Object;)Ljava/util/Optional

ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NoSuchMethodError: org.springframework.plugin.core.PluginRegistry.getPluginFor(Ljava/lang/Object;)Ljava/util/Optional;

错误原因：

springfox自带的spring-plugin-core-1.2.0.RELEASE.jar 版本不兼容

解决方法：

导入spring-plugin-core-2.0.0.RELEASE.jar

    <dependency>
        <groupId>org.springframework.plugin</groupId>
        <artifactId>spring-plugin-core</artifactId>
        <version>2.0.0.RELEASE</version>
    </dependency>

即可
