java.lang.AssertionError：响应内容

我试图测试

UnitTest

，但得到

java.lang.AssertionError:Response内容

运行测试时。
我的日志猫

问题: 我无法获得如何匹配这两个字符串以通过测试。谢谢你的帮助

当调用其

toString（）

方法时，您试图将内容字符串与实际对象进行比较，如下所示：

Expected: <[UserDTO [firstName=Ahmad, lastName=shahzad, userName=1, emailAddress=ahmad.shahzad@null], UserDTO [firstName=Jamshaid, lastName=iqbal, userName=2, emailAddress=jamshaid.ali@null], UserDTO [firstName=Waqas, lastName=Akram, userName=3, emailAddress=waqas.akram@null]]>
 but: was "[{\"firstName\":\"Ahmad\",\"lastName\":\"shahzad\",\"userName\":\"1\",\"emailAddress\":\"ahmad.shahzad@null\"},{\"firstName\":\"Jamshaid\",\"lastName\":\"iqbal\",\"userName\":\"2\",\"emailAddress\":\"jamshaid.ali@null\"},{\"firstName\":\"Waqas\",\"lastName\":\"Akram\",\"userName\":\"3\",\"emailAddress\":\"waqas.akram@null\"}]"

预期：
但是：是“[{\“firstName\”：“Ahmad\”，“lastName\”：“shahzad\”，“userName\”：“1\”，“emailAddress\”：“Ahmad”。shahzad@null\“}，{\'firstName\'：\'Jamshaid\'，\'lastName\'：\'iqbal\'，\'userName\'：\'2\'，\'emailAddress\'：\'Jamshaid。ali@null\“}、{\'firstName\'：\'Waqas\'、\'lastName\'：\'Akram\'、\'userName\'：\'3\'、\'emailAddress\'：\'Waqas。akram@null\"}]"

您必须解析内容中的每个属性，或者使用某种JSON解析器进行批量解析。然后将每个解析的属性与用户对象的字段进行比较。

您需要使用

json（）

，而不是

string（）

，因为您的响应在内部转换为json。并使用

com.fasterxml.jackson.databind.ObjectMapper

中的

ObjectMapper

将响应列表转换为JSON

@Test
public void getHello() throws Exception {
ObjectMapper mapper = new ObjectMapper();
String result = mapper.writeValueAsString(new UserController().getUsers());
    mvc.perform(MockMvcRequestBuilders.get("/auth").accept(MediaType.APPLICATION_JSON))
            .andExpect(status().isOk())
            .andExpect(content().json(result));
}

---

编辑：您可以使用ObjectMapper将对象列表转换为JSON。

new UserController（）.getUsers（））

返回一个

列表，您试图将其与mvc框架上下文中调用返回的JSON字符串进行比较。我知道，那显然行不通。但是没有找到一种方法来比较它们如何模拟MVCrequestBuilders配置我应该如何使用JSON解析器？你必须弄清楚。关键是，不能在字符串和实际对象上断言等于。toString（）。
getUsers（）
将返回一个列表。如何将其更改为JSON？它在添加依赖项后解决了错误
