SpringBoot配置Sentinel控制台，异常java.lang.IllegalAccessError
在使用Sentinel控制台时，出现异常信息：
2022-04-16 11:15:06.316 ERROR 2951 --- [nio-8080-exec-8] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler dispatch failed; nested exception is java.lang.IllegalAccessError: class com.alibaba.csp.sentinel.dashboard.controller.MachineRegistryController (in unnamed module @0x3a41bef7) cannot access class sun.net.util.IPAddressUtil (in module java.base) because module java.base does not export sun.net.util to unnamed module @0x3a41bef7] with root causejava.lang.IllegalAccessError: class com.alibaba.csp.sentinel.dashboard.controller.MachineRegistryController (in unnamed module @0x3a41bef7) cannot access class sun.net.util.IPAddressUtil (in module java.base) because module java.base does not export sun.net.util to unnamed module @0x3a41bef7
Sentinel控制台版本是1.8.4，JDK17，SpringBoot2.6.4，pom依赖如下：
<!-- SpringCloud 依赖--><dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>2021.0.1</version>
<type>pom</type>

</dependency>
<!-- SpringCloud alibaba 依赖-->

<!--sentinel-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
<version>2021.0.1.0</version>
</dependency>
测试接口代码：
@RestControllerpublic class TestController {
@GetMapping(value = "/hello")
public String hello() {
return "hello sentinel!";
}
}
application.properties 配置文件：
server.port=8087spring.application.name=sentineldemo
spring.cloud.sentinel.transport.dashboard=localhost:8080
Sentinel控制台可以正常启动，当后台服务运行之后，便会出现上述异常，异常全部信息如下：
