异常关键字：

Cannot assign requested address: bind

排查结果

配置了环境变量【SERVER_ADDRESS】

网上搜了有的回答是端口占用，是不对的，端口占用的异常是这个【Web server failed to start. Port 8282 was already in use.】

排查结果非常曲折，提供关键字供参考

• org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory#getWebServer
• org.springframework.boot.context.properties.bind.Binder#bind(org.springframework.boot.context.properties.source.ConfigurationPropertyName, org.springframework.boot.context.properties.bind.Bindable, org.springframework.boot.context.properties.bind.BindHandler, org.springframework.boot.context.properties.bind.Binder.Context, boolean, boolean)
• org.springframework.boot.context.properties.bind.JavaBeanBinder#bind(org.springframework.boot.context.properties.bind.JavaBeanBinder.BeanSupplier, org.springframework.boot.context.properties.bind.DataObjectPropertyBinder, org.springframework.boot.context.properties.bind.JavaBeanBinder.BeanProperty)
• 条件断点 “address”.equals(propertyName)
  
• org.springframework.boot.context.properties.bind.Binder#findProperty
  

到此是找到位置了

我的天，一个早上，终于找到位置了，但是还是不知道哪里的问题，执行如下代码发现，getenv这里有，因为里面有JAVA_HOME，那还我配置的环境变量。果然是他。
这台电脑不是全新的，不知道上个使用者为什么要配置这个，也算是问题找到了，删了这个，完成。

    @Test
    public void testHost() {
        System.getProperties().forEach((k, v) -> System.out.println(k + " ==> " + v));
    }
    @Test
    public void testEnv() {
        System.getenv().forEach((k, v) -> System.out.println(k + " ==> " + v));
    }
