TypeError: Failed to execute 'fetch' on 'Window': Request with GET/HEAD method c

swagger 报错：

TypeError: Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body.

 

有@ResponseBody才会在接口中获取swagger列表

 

 

是由于方法中申明的是get方法却用了@requestBody 

 

RequestMethod.POST---》@RequestBody

 

RequestMethod.POST---》@RequestParam  这个也是从body中获取也可从url后获取

 

RequestMethod.GET---》这种可以有参数用模型驱动，或者属性驱动获取，但是不可以用@注解从body获取

 (不需要注解)  从url后获取

 @PathVariable   斜杠路劲中获取

 

 

 

 

 

  @ResponseBody

    @RequestMapping(value = { "/listFunc" }, method = RequestMethod.POST,produces="application/json;charset=UTF-8")

    @ApiResponses(value = {@ApiResponse(code = 200, message = "角色功能信息",  response=String.class),

            @ApiResponse(code = 201, message = "q"+ "(token验证失败)",  response=String.class),

            @ApiResponse(code = 202, message = "500" + "(系统错误)",response = String.class)})

    @ApiOperation(value="查询列表",notes="/list",response = String.class)

    public  BaseResponse<List<FinancialSalesFunc>> listFunc(@RequestBody(required = false) FinancialSalesRole financialSalesRole) {

 

 

    }

  

 

     @RequestMapping(value = { "/modal" }, method = RequestMethod.GET)

    public String customerinfo(CoreBusinessTypeCondition condition, ModelMap modelMap) throws IOException {

 

}

 

 

在spring MVC中，两者的作用都是将request里的参数的值绑定到contorl里的方法参数里的，区别在于，URL写法不同。

使用@RequestParam时，URL是这样的：http://host:port/path?参数名=参数值

使用@PathVariable时，URL是这样的：http://host:port/path/参数值

例如：

 

@RequestMapping(value="/user",method = RequestMethod.GET)
   public @ResponseBody
   User printUser(@RequestParam(value = "id", required = false, defaultValue = "0")
   int id) {
    User user = new User();
       user = userService.getUserById(id);
       return user;
   }

   @RequestMapping(value="/user/{id:\\d+}",method = RequestMethod.GET)
   public @ResponseBody
   User printUser2(@PathVariable int id) {
       User user = new User();
       user = userService.getUserById(id);
       return user;
   }
