学习使用MockMvc请求，post请求，参数都是一样的。Get请求，参数就不同了。对于不同类型的参数，改如何处理呢？
1，参数在URL上的Path
PathVariable
@ResponseBody
@GetMapping("/inst/{tableId}")
public Object getAopsInst(@PathVariable Long tableId) {
??? return tableId+" I will make it";
}测试：
@Test
public void testPathParam() throws Exception {
??? Long tableId = 2022318L;
??? mockMvc.perform(MockMvcRequestBuilders.get("/aop/inst/"+tableId)).andDo(print())
??????????? .andExpect(MockMvcResultMatchers.status().isOk());
}结果：
MockHttpServletResponse:
?????????? Status = 200
??? Error message = null
????????? Headers = [Content-Type:"text/plain;charset=UTF-8", Content-Length:"22"]
???? Content type = text/plain;charset=UTF-8
?????? ??????Body = 2022318 I will make it
??? Forwarded URL = null
?? Redirected URL = null
????????? Cookies = []2，单个参数
单个RequestParam
@ResponseBody
@GetMapping("/getTypeInfoByType")
public Object getTypeInfoByType(@RequestParam("type") String type) {
??? return type+" single param";
}测试：
@Test
public void testGetSingleParam() throws Exception {
??? String type = "ALARM_CLASS";
??? mockMvc.perform(MockMvcRequestBuilders.get("/aop/getTypeInfoByType").param("type", type)).andDo(print())
??????????? .andExpect(MockMvcResultMatchers.status().isOk());
}结果：
MockHttpServletResponse:
?????????? Status = 200
??? Error message = null
????????? Headers = [Content-Type:"text/plain;charset=UTF-8", Content-Length:"24"]
???? Content type = text/plain;charset=UTF-8
???????????? Body = ALARM_CLASS single param
??? Forwarded URL = null
?? Redirected URL = null
????????? Cookies = []3，多个参数：
多个RequestParam
@ResponseBody
@GetMapping("/getTypeInfoByTypes")
public Object getTypeInfoByTypes(@RequestParam("type") String type,
@RequestParam(value = "state", required = false) String state) {
return "type: "+ type+" and state "+state +" double param";
}
处理：
多个时候，怎么处理呢？
public MockHttpServletRequestBuilder params(MultiValueMap<String, String> params)
MultiValueMap 具体实现 ?熟悉的是LinkedMultiValueMap
?MultiValueMap 是多指映射
?
测试：
@Test
public void testGetMulParams() throws Exception {
String type = "ALARM_CLASS";
String state = "0SA";
MultiValueMap<String, String> params = new LinkedMultiValueMap<>();
params.put("type", Collections.singletonList(type));
params.put("state", Collections.singletonList(state));
mockMvc.perform(MockMvcRequestBuilders.get("/aop/getTypeInfoByTypes").params(params)).andDo(print())
.andExpect(MockMvcResultMatchers.status().isOk());
}
结果：
MockHttpServletResponse:
?????????? Status = 200
??? Error message = null
????????? Headers = [Content-Type:"text/plain;charset=UTF-8", Content-Length:"44"]
???? Content type = text/plain;charset=UTF-8
???????????? Body = type: ALARM_CLASS and state 0SA double param
??? Forwarded URL = null
?? Redirected URL = null
????????? Cookies = []总结：
????????使用MockMvc可以模拟postman的请求，post方式参数处理是一致的。Get方式内容会多一些。主要是多个的处理是使用MultiValueMap
?
