Error resolving template [date], template might not exist or might not be accessible by any of the configured Template Resolvers

这种情况要不就是你想加载页面

@RequestMapping("/welcome1.html")
public String welcome1(){
    return "/welcome1";
}

但写错了

改正：

@RequestMapping("/welcome1.html")
public String welcome1(){
    return "welcome1";
}

或者你想return一个值

加入注解

@ResponseBody

返回
