Spring JsonPath 包含任何顺序异常

Spring JsonPath contains in any order exception

我正在用 spring 编写一些集成测试,想检查响应中的 json 是否包含所有必需的数据。见代码:

@Test
public void getAll() throws Exception {
    String url = "/permissions/all";
    int size = 4;
    try {
        Set<String> permissions = RandomGenerator.randomStrings(size);
        initDb(permissions);
        mvc.perform(get(url).with(Users.PERMISSIONS_READ))
                .andExpect(jsonPath("$[?(@.name)].name", hasSize(size))) //ok
                .andExpect(jsonPath("$[?(@.name)].name").value(containsInAnyOrder(permissions))); //exception
    } finally {
        dropDb();
    }
}

但我遇到了一个例外:

java.lang.AssertionError: JSON path "$[?(@.name)].name"

Expected: iterable over [<[b0ce9e8a-8b62-41f4-91b9-d9cf6ff96675, 7ebe3a4f-7864-4ea5-92b3-a5ad6f44bf42, 7df2fa88-b22f-4d33-91b2-f8b00813522f, 17b61119-c48c-4dff-ac9c-047eb3efcc43]>] in any order
 but: Not matched: "7df2fa88-b22f-4d33-91b2-f8b00813522f"

以及来自此响应的数据:

[{
    "id": 1,
    "name": "7df2fa88-b22f-4d33-91b2-f8b00813522f" 
}, {
    "id": 2,
    "name": "b0ce9e8a-8b62-41f4-91b9-d9cf6ff96675"
}, {
    "id": 3,
    "name": "7ebe3a4f-7864-4ea5-92b3-a5ad6f44bf42"
}, {
    "id": 4,
    "name": "17b61119-c48c-4dff-ac9c-047eb3efcc43"
}]

我知道,选择器 $[?(@.name)].name 工作正常,returns 结果如下:

[
  "7df2fa88-b22f-4d33-91b2-f8b00813522f",
  "b0ce9e8a-8b62-41f4-91b9-d9cf6ff96675",
  "7ebe3a4f-7864-4ea5-92b3-a5ad6f44bf42",
  "17b61119-c48c-4dff-ac9c-047eb3efcc43"
]

permissions set 也是正确的,包含上面示例中的 4 个字符串。

有人可以告诉我我做错了什么吗?

这会起作用:

Set<String> permissions = RandomGenerator.randomStrings(size);
initDb(permissions);
mvc.perform(get(url).with(Users.PERMISSIONS_READ))
    .andExpect(jsonPath("$[?(@.name)].name", hasSize(size))) //ok
    .andExpect(jsonPath("$[?(@.name)].name").value(containsInAnyOrder(permissions.toArray(new String[permissions.size()]))));

或重申:

String[] permissions = RandomGenerator.randomStrings(size);
initDb(permissions);
mvc.perform(get(url).with(Users.PERMISSIONS_READ))
    .andExpect(jsonPath("$[?(@.name)].name", hasSize(size))) //ok
    .andExpect(jsonPath("$[?(@.name)].name").value(containsInAnyOrder(permissions)));

这是containsInAnyOrder的签名:

public static <T> Matcher<Iterable<? extends T>> containsInAnyOrder(T... items)

因此,它需要一个与您声明反对的 相同 类型的可变参数。在您的情况下,您针对 String 类型进行断言,但您向 containsInAnyOrder 提供 Set<String>,因此 String 和 Set 之间的匹配失败。
