restTemplate基本用法

 1 @Data
 2     class User{
 3         private String name;
 4         private Double price;
 5     }
 6     //get请求无参数
 7     @Test
 8     void fun1(){
 9         String url = "http://localhost:8082/get";
10         String result = restTemplate.getForObject(url, String.class);
11         System.out.println(result);
12     }
13 
14     //get请求 有参 
15     @Test
16     void fun2(){
17         String url = "http://localhost:8082/getP?name='dfdsf'";
18         String result = restTemplate.getForObject(url, String.class);
19         System.out.println(result);
20     }
21     @Test
22     void fun3(){
23         String url = "http://localhost:8082/getP?name='dfdsf'";
24         ResponseEntity<String> forEntity = restTemplate.getForEntity(url, String.class);
25         System.out.println(forEntity);
26     }
27 
28     @Test
29     void fun4(){
30         String url = "http://localhost:8082/find";
31         LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
32         map.add("name","zhangsna");
33         map.add("price",9.99D);
34         ResponseEntity<String> stringResponseEntity = restTemplate.postForEntity(url, map, String.class);
35         System.out.println(stringResponseEntity);
36     }
37     
38     @Test
39     void fun5(){
40         String url = "http://localhost:8082/postF";
41         User user = new User();
42         user.setName("lisi");
43         user.setPrice(999D);
44         ResponseEntity<String> stringResponseEntity = restTemplate.postForEntity(url, user, String.class);
45         System.out.println(stringResponseEntity);
46     }

 1     @GetMapping("/get")
 2     public String find(){
 3         return "ok";
 4     }
 5 
 6     @GetMapping("/getP")
 7     public String getP(String name){
 8         return name;
 9     }
10 
11     @PostMapping("/find")
12     public String postFind(String name,Double price){
13         return new User(1,name,price).toString();
14     }
15 
16     @PostMapping("/postF")
17     public String postF(@RequestBody User user){
18         return user.toString();
19     }
