上面是通过idea 的快照打开的，下面是正常日志打印

造成的原因是因为我在 comtroler 里面增加了一个普通的方法 把方法删掉就能正常启动 加上方法项目启动就被卡了。方法如下
@GetMapping("/downloadPropExcel/{ids}")
public String downloadPropExcel(HttpServletRequest request, HttpServletResponse response,@PathVariable List<Integer> ids){

String operId = this.getAqCzy().getOperId();
    return null;

}

Answer 1

这么用不对，@PathVariable不支持绑定List类型。

@PathVariable List<Integer> ids

官方API文档描述如下：

Annotation which indicates that a method parameter should be bound to a URI template variable. Supported for RequestMapping annotated handler methods.

If the method parameter is Map<String, String> then the map is populated with all path variable names and values.

如果你想接收一个List，可以使用@RequestParam
