Springboot 接口对接文件和对象

两个sprongboot项目实现文件对接，在传入文件同时传递其他对象信息，比如接口如下

一、创建文件

例如在D盘下创建1.txt，里边写入内容

 2、传送方代码实现

1.  
    
2.  
    
3.  
   import org.springframework.core.io.FileSystemResource;
4.  
   import org.springframework.http.*;
5.  
   import org.springframework.util.LinkedMultiValueMap;
6.  
   import org.springframework.util.MultiValueMap;
7.  
   import org.springframework.web.bind.annotation.GetMapping;
8.  
   import org.springframework.web.bind.annotation.RequestMapping;
9.  
   import org.springframework.web.bind.annotation.RestController;
10.  
    import org.springframework.web.client.RestTemplate;
11.  
     
12.  
    import java.io.File;
13.  
     
14.  
    /**
15.  
    * Created by HJ
16.  
    */
17.  
    @RestController
18.  
    @RequestMapping("/send")
19.  
    public class test {
20.  
     
21.  
    @GetMapping("/sendFile")
22.  
    public ResponseEntity<String> sendFile( ){
23.  
    //接口地址
24.  
    String remote_url="http://localhost:8081/receiv/receivFile";
25.  
    File file=new File("D:\\1.txt");
26.  
    RestTemplate restTemplate = new RestTemplate();
27.  
    MultiValueMap<String, Object> body = new LinkedMultiValueMap<>();
28.  
    body.add("file", new FileSystemResource(new File("D:\\1.txt")));
29.  
    Student student= new Student(1,"张三",12);
30.  
    body.add("student",student);
31.  
    HttpHeaders headers = new HttpHeaders();
32.  
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);
33.  
    HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(body, headers);
34.  
    ResponseEntity<String> response = restTemplate.exchange(remote_url, HttpMethod.POST, requestEntity, String.class);
35.  
     
36.  
    return response;
37.  
    }
38.  
    static class Student {
39.  
    private int id;
40.  
    private String name;
41.  
    private int age;
42.  
    public Student(int id,String name,int age){
43.  
    this.id=id;
44.  
    this.name=name;
45.  
    this.age=age;
46.  
    }
47.  
    public Student(){
48.  
     
49.  
    }
50.  
    public int getId(){
51.  
    return id;
52.  
    }
53.  
    public String getName(){
54.  
    return name;
55.  
    }
56.  
    public int getAge(){
57.  
    return age;
58.  
    }
59.  
    @Override
60.  
    public String toString(){
61.  
    return id " " name " " age;
62.  
    }
63.  
    public void setId(int id){
64.  
    this.id=id;
65.  
    }
66.  
    public void setName(String name){
67.  
    this.name=name;
68.  
    }
69.  
    public void setAge(int age){
70.  
    this.age=age;
71.  
    } }
72.  
     
73.  
    }

3.接收方代码实现

1.  
    
2.  
   import org.springframework.web.bind.annotation.RequestMapping;
3.  
   import org.springframework.web.bind.annotation.RequestMethod;
4.  
   import org.springframework.web.bind.annotation.RequestPart;
5.  
   import org.springframework.web.bind.annotation.RestController;
6.  
   import org.springframework.web.multipart.MultipartFile;
7.  
    
8.  
   import java.io.IOException;
9.  
    
10.  
    /**
11.  
    * Created by HJ
12.  
    */
13.  
    @RestController
14.  
    @RequestMapping("/receiv")
15.  
    public class testb {
16.  
    @RequestMapping(value = "/receivFile", method = RequestMethod.POST)
17.  
    public String receivFile(@RequestPart("file") MultipartFile file,
18.  
    @RequestPart("student") Student student) throws IOException {
19.  
    byte[] bytes = file.getBytes();
20.  
    String s = new String(bytes);
21.  
    //InputStream inputStream=file.getInputStream();
22.  
    System.out.println("文件内容为:" s);
23.  
    System.out.println("文件名称：" file.getOriginalFilename());
24.  
    System.out.println("对象内容：" student.toString());
25.  
    return "对接成功";
26.  
     
27.  
    }
28.  
    static class Student {
29.  
    private int id;
30.  
    private String name;
31.  
    private int age;
32.  
    public Student(int id,String name,int age){
33.  
    this.id=id;
34.  
    this.name=name;
35.  
    this.age=age;
36.  
    }
37.  
    public Student(){
38.  
     
39.  
    }
40.  
    public int getId(){
41.  
    return id;
42.  
    }
43.  
    public String getName(){
44.  
    return name;
45.  
    }
46.  
    public int getAge(){
47.  
    return age;
48.  
    }
49.  
    @Override
50.  
    public String toString(){
51.  
    return "id:" id " name: " name " age:" age;
52.  
    }
53.  
    public void setId(int id){
54.  
    this.id=id;
55.  
    }
56.  
    public void setName(String name){
57.  
    this.name=name;
58.  
    }
59.  
    public void setAge(int age){
60.  
    this.age=age;
61.  
    } }
62.  
    }

4、测试

界面输入传送方项目路径，比如：http://localhost:8082/send/sendFile

界面返回信息 

 接收方控制台输出
