这是端点实现（字段中缺少一些详细信息）：
@ManagedOperation
public synchronized ConfigurableApplicationContext restart() {
if (this.context != null) {
if (this.integrationShutdown != null) {
this.integrationShutdown.stop(this.timeout);
}
this.application.setEnvironment(this.context.getEnvironment());
this.context.close();
overrideClassLoaderForRestart();
this.context = this.application.run(this.args);
}
return this.context;
}
