restTemplate基本用法

@Data
    class User{
        private String name;
        private Double price;
    }
    //get请求无参数
    @Test
    void fun1(){
        String url = "http://localhost:8082/get";
        String result = restTemplate.getForObject(url, String.class);
        System.out.println(result);
    }

    //get请求 有参 
    @Test
    void fun2(){
        String url = "http://localhost:8082/getP?name='dfdsf'";
        String result = restTemplate.getForObject(url, String.class);
        System.out.println(result);
    }
    @Test
    void fun3(){
        String url = "http://localhost:8082/getP?name='dfdsf'";
        ResponseEntity<String> forEntity = restTemplate.getForEntity(url, String.class);
        System.out.println(forEntity);
    }

    @Test
    void fun4(){
        String url = "http://localhost:8082/find";
        LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
        map.add("name","zhangsna");
        map.add("price",9.99D);
        ResponseEntity<String> stringResponseEntity = restTemplate.postForEntity(url, map, String.class);
        System.out.println(stringResponseEntity);
    }
    
    @Test
    void fun5(){
        String url = "http://localhost:8082/postF";
        User user = new User();
        user.setName("lisi");
        user.setPrice(999D);
        ResponseEntity<String> stringResponseEntity = restTemplate.postForEntity(url, user, String.class);
        System.out.println(stringResponseEntity);
    }

    @GetMapping("/get")
    public String find(){
        return "ok";
    }

    @GetMapping("/getP")
    public String getP(String name){
        return name;
    }

    @PostMapping("/find")
    public String postFind(String name,Double price){
        return new User(1,name,price).toString();
    }

    @PostMapping("/postF")
    public String postF(@RequestBody User user){
        return user.toString();
    }
