@Test

            .content("{\"id\": 1, \"name\": \"John\"}");

    // 发送请求并获取响应结果
    MvcResult result = mockMvc.perform(requestBuilder)
            .andExpect(MockMvcResultMatchers.status().isOk())
            .andReturn();

    // 验证响应结果是否符合预期
    String response = result.getResponse().getContentAsString();
    Assert.assertEquals("Data saved successfully", response);
