Java Mockito MVC-如何为@RequestParam绑定字符串数组传递值

我想用Mockito编写一个单元测试

测试方法由Spring MVC编写，如下所示：

@RequestMapping(value = "/save", method = RequestMethod.POST, produces = "text/html;charset=UTF-8")
@ResponseBody
public String save(String appName,
        @RequestParam(value = "platforms[]") String[] platforms,
        HttpServletRequest request) {}

我尝试了几种方法来模拟请求值平台，即绑定字符串数组，比如“string[]”

但是，它似乎仍然不起作用：platforms值为null

以下是我尝试的方法：

Way#1

final String[] platforms = { "Android", "iOS" };
request.setAttribute("platforms", platforms);
request.setAttribute("platforms[]", platforms);

Way#2

mockMvc.perform(MockMvcRequestBuilders.post("/application/save")
            .session(session).requestAttr("platforms[]", platforms)
            .requestAttr("platforms", platforms)
            .param("appName", "Just for test"));

注意：请求是一个模拟对象（MockHttpServletRequest）

希望你能给我一些想法来解决这个问题。谢谢

有关更多信息，请参见按第2种方式打印时的打印结果：

如果在路径2上的.perform之后添加.andDo（print（）），将打印什么？（print（）是MockMvcResultHandlers的一个方法）。@Jean-FrançoisSavard感谢您的建议。某些信息打印如下：MockHttpServletResponse:Status=400错误消息=必需的字符串[]参数“platforms[]”不存在标头={}内容类型=null Body=转发URL=null重定向URL=null Cookies=[]尝试将平台作为.param而不是requestAttr传递。根据文档，.param用于设置请求参数，而requestAttr用于设置请求属性。@Jean FrançoisSavard感谢您的建议。我尝试设置一个请求参数，如。param（“platforms[]”，“Andriod，iOS”）。param（“platforms”，“Andriod，iOS”）正在工作，谢谢

MockHttpServletRequest:
     HTTP Method = POST
     Request URI = /application/save
      Parameters = {appName=[Just for test]}
         Headers = {}

         Handler:
            Type = com.xxx.controller.ApplicationController
          Method = public java.lang.String com.xxx.controller.ApplicationController.save(java.lang.String,java.lang.String[],javax.servlet.http.HttpServletRequest)

Resolved Exception:
            Type = org.springframework.web.bind.MissingServletRequestParameterException

    ModelAndView:
       View name = null
            View = null
           Model = null

        FlashMap:

 MockHttpServletResponse:
          Status = 400
   Error message = Required String[] parameter 'platforms[]' is not present
         Headers = {}
    Content type = null
            Body = 
   Forwarded URL = null
  Redirected URL = null
         Cookies = []
