postman请求提交用表单方式提交(List对象)格式的数据 

1.demo

package com.aa;

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

@Getter
@Setter
@ToString
public class StaffAddVo implements Serializable {
    private List positionIdList;

    @Getter
    @Setter
    @ToString
    public static class Position{
        private String id;
        private String name;
    }
}

2.postman测试传参
传参格式示例:
positionIdList[0].id
positionIdList[0].name

3.测试结果

 4.总结

用List> 格式接收不到参数，改成List<对象>的格式，即可接收

使用MOCKMvc测试文件上传功能
关键点：

MockMvcRequestBuilders.fileUpload(“你的接口地址”).file（MockMultipartFile）

MockMultipartFile（String name, String originalFilename, String contentType, InputStream contentStream），这个构造方法中第一个值name注意要对应接口中的MutipartFile file参数的名字，否则会上传失败。

@Test
public void fileTest() throws Exception {
        ResultActions resultActions = mockMvc.perform(MockMvcRequestBuilders.fileUpload("/SSM/api/file/upload").
                file(new MockMultipartFile("file", "test", "application/ms-excel", new FileInputStream(new File("C:/Users/Administrator/Desktop/test.xls")))));
        MvcResult mvcResult = resultActions.andDo(MockMvcResultHandlers.print()).andExpect(MockMvcResultMatchers.status().isOk()).andReturn();
        String result = mvcResult.getResponse().getContentAsString();
        System.out.println("==========结果为：==========\n" + result + "\n");
    }

@Controller
public class NewController {  
@RequestMapping(value = "/upload", method = RequestMethod.POST)    
@ResponseBody    
public String saveAuto(@RequestPart(value = "json") JsonPojo pojo,@RequestParam(value = "some-random") String random,@RequestParam(value = "data", required = false) List files) 
{        
　　System.out.println(random);        
　　System.out.println(pojo.getJson());        
　　for (MultipartFile file : files) {            
　　System.out.println(file.getOriginalFilename());        
　　}
　　return "success";    
}    

static class JsonPojo {        
　　private String json;        
　　public String getJson(){return json;}        
　　public void setJson(String json){this.json = json;}
　　}
}


@WebAppConfiguration
@ContextConfiguration(classes = WebConfig.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class Example {   
@Autowired
private WebApplicationContext webApplicationContext;    

@Test
public void test() throws Exception {       
　　MockMultipartFile firstFile = new MockMultipartFile("data", "filename.txt", "text/plain", "some xml".getBytes());        
　　MockMultipartFile secondFile = new MockMultipartFile("data", "other-file-name.data", "text/plain", "some other type".getBytes());  

　　MockMultipartFile jsonFile = new MockMultipartFile("json", "", "application/json", "{\"json\": \"someValue\"}".getBytes());        
　　MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build(); 
　　mockMvc.perform(MockMvcRequestBuilders.fileUpload("/upload")                        
　　.file(firstFile)
　　.file(secondFile)
　　.file(jsonFile)
　　.param("some-random", "4")
    )
　　.andExpect(status().is(200))                    
　　.andExpect(content().string("success"));    
}}
