当我在Spring Boot中为HTTP PUT请求运行JUNIT方法时，出现以下错误跟踪。
输入的JSON值已成功传递到服务方法。但是，HTTP servlet响应中没有任何响应。
当我点击邮递员中的服务URL时，请求的输入将为JSON，而我们得到的响应也是JSON。
PUT请求
@Test
public void updateMilestoneTest() throws Exception {
Milestone milestone = new Milestone("100","MSJunit2","description","test2","mahi","mahi", null);
milestone.setCreatedBy("auth");
milestone.setCreatedDate(null);
milestone.setUpdatedBy("auth");
milestone.setLastModifiedDate(null);
when(milestoneService.updateMilestone("100",milestone)).thenReturn(milestone);
String updateMilestoneJSON = "{\"milestoneId\":100,\"milestoneName\":\"MSJunit2\",\"description\":\"description\",\"condition\":\"test2\",\"createdBy\":\"auth\",\"updatedBy\":\"auth\",\"milestoneSynonymMappings\":null}";
mockMvc.perform(put("/milestone/updateMilestone/100").contentType("application/json;charset=UTF-8").content(updateMilestoneJSON)).andExpect(status().isOk())
.andExpect(content().contentType("application/json;charset=UTF-8"))
.andExpect(jsonPath("$.milestoneId").value(100)).andExpect(jsonPath("$.milestoneName").value("MSJunit2"))
.andExpect(jsonPath("$.description").value("description")).andExpect(jsonPath("$.createdBy").value("auth"));
}
Below is the error trace. I hope we should set content type as application/json only
