Spring 调用具有多个@RequestParam自定义对象的GET api

搜索了很多，通过多个帖子，但没有得到我想要的

我的控制器中有以下方法

@GetMapping("/{workflowId}")
public ResponseEntity<String> callme(@PathVariable Integer workflowId,
        @RequestParam(required = false, defaultValue = "false") Boolean isMock,
        @RequestParam(required = true) UserContext userContext,
        @RequestParam(required = true) Integer execFlags,
        @RequestParam(required = false) Object arg1, 
        @RequestParam(required = false) AMExecution parent, 
        @RequestParam(required = false) CRDetailsDTO userInput,
        HttpServletRequest httpRequest)  {

    System.out.println("In callme");
    System.out.println("workflowId: " + workflowId + " usercontext: " + userContext + " execFlags: " + execFlags
            + " arg1: " + arg1 + " parent: " + parent + " userInput: " + userInput);
    workflowService.executeWorkflow(userContext, workflowId, execFlags, arg1, parent, userInput);
    return new ResponseEntity<String>(HttpStatus.OK);
}

@GetMapping（“/{workflowId}”）
public ResponseEntity callme（@PathVariable Integer workflowId，
@RequestParam（required=false，defaultValue=“false”）布尔isMock，
@RequestParam（required=true）UserContext UserContext，
@RequestParam（必需=true）整数执行标志，
@RequestParam（必需=false）对象arg1，
@RequestParam（required=false）AMExecution父级，
@RequestParam（required=false）CRDetailsDTO userInput，
HttpServletRequest（httpRequest）{
System.out.println（“In callme”）；
System.out.println（“workflowId:+workflowId+”usercontext:+usercontext+”execFlags:+execFlags
+“arg1:”+arg1+“父项：”+parent+“用户输入：”+userInput）；
executeWorkflow（userContext、workflowId、execFlags、arg1、父项、userInput）；
返回新的响应状态（HttpStatus.OK）；
}

我想知道如何使用resttemplate调用此方法。我需要知道如何从调用方传递UserContext和其他用户定义的对象
