Spring actuator 访问’/auditevents’ endpoint 返回404

在使用Spring Boot Actuator的项目中，当访问/actuator/auditevents端点时，返回结果为404，为什么没有正常显示出来呢？

pom.xml依赖如下：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

application.properties的配置如下：

management.endpoints.web.exposure.include=*

但当访问http://localhost:8080/actuator时并未出现/auditevents的端点：

        }
    }
}

为什么会出现这种情况呢？

这是因为审计功能的开启需要在应用程序中提供类型为AuditEventRepository的Bean，也就是说Spring容器中需要实例化这样一个Bean。

这里可以通过是实例化AuditEventRepository的子类InMemoryAuditEventRepository来实现：

@Configuration
public class AuditEventConfig {

	@Bean
	public InMemoryAuditEventRepository repository(){
		return new InMemoryAuditEventRepository();
	}
}

重启并再次访问，便可以看到auditevents端点了，并且直接访问该端点会展示相应的内容了。
