我正在对正在开发的Web应用程序进行单元测试，并且在测试控制器的某些功能时遇到问题。
基本上，我正在创建一个模拟计算机，我想将先前创建的对象传递给它。代码是这样的：
Connection connection1 = new Connection();
connection1.setStatus(Status.IN);
connection1.setConnectionId("countingCamera1Conn");
connection1.setPath("urlPath");
connection1.setUsername("userName");
when(connectionRepoMock.existsById(anyString())).thenReturn(true);
//then
mockMvc.perform(post("/model/connection")
.content(asJsonString(connection1))
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isCreated())
;
控制器每个参数接收两个对象。该控制器是使用视图创建指示对象的新记录的控制器。
@PostMapping("model/connection")
public String addConnection(Connection connection, Model model) {
checkRole(model);
if(!checkElement(connection,model))
return "error";
if(controllerRepo.existsById(connection.getConnectionId())) {
model.addAttribute("errorMsg", "The Id already exists, please try another one");
return "error";
}
controllerRepo.save(connection);
return "redirect:/model/connection";
}
我已验证，如果在addConnection()方法中放入了@RequestBody标记，则该测试对我有效，但从Web停止运行。我该如何模拟控制器通过模拟Mvc接收到的对象？
[从视图上看，我正在使用“ thymeleaf”从HTML表单生成新记录。来源是这样的：
<div class="form-group row px-md-4">
<h1>Connection</h1>
<div class="col-sm-1 py-sm-1">
<button class="btn btn-primary" type="button" data-toggle="modal"
data-target="#addConnection" value="Add a connection" rel="tooltip"
title="Add a new connection">
<i class="fa fa-plus"></i>
</button>
</div>
<!-- Modal -->
<div class="modal fade" id="addConnection" tabindex="-1"
role="dialog" aria-labelledby="#addConnectionTitle"
aria-hidden="true">
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="addConnectionTitle">Add a

<button type="button" class="close" data-dismiss="modal"
aria-label="Close">

</button>
</div>
<div class="modal-body">

<!-- End of Modal -->

非常感谢。
显然，HTL表单将值作为参数发送给控制器。 @M注释，当更改嘲笑Mvc以将值作为参数而不是作为json主体传递时。 Deinum已修复该错误。
代码如下：
mockMvc.perform(post("/model/connection")
.param("connectionId", "countingCamera1Conn")
.param("path", "urlPath")
.param("status", "IN")
.param("username", "username")
.contentType(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isCreated())
;
您应该使用@RequestBody。为什么停止工作？请解释问题
