spring boot 请求 rest 服务

 springboot 环境搭建不多讲，直接代码

配置

在启动类里加入如下配置

---

    @Autowired
    private RestTemplateBuilder builder;

	// 使用RestTemplateBuilder来实例化RestTemplate对象，spring默认已经注入 RestTemplateBuilder
	@Bean
	public RestTemplate restTemplate() {
		return builder.build();
	}

 接下里是controller类里注入RestTemplate 

  @Autowired
  private RestTemplate restTemplate;

代码测试

这里看一下，底下用来测试的实体类

@Data
@Component
public class Device {

    private Integer id;

    private String type;

    private String manufactor;  //生产厂家

    @JsonFormat(shape=JsonFormat.Shape.STRING, pattern="yyyy-MM-dd'T'HH:mm:ss+0800",timezone = "GMT+8:00")
    private Date registerTime;

}

如下是详细的增删改查的调用，前面的path变量是我设置一个rest路径，这里自行改

 /*
        查询某个设备信息
     */
    @GetMapping("/getDevice/{id}")
    public String getDevice(@PathVariable int id){
        String forObject = restTemplate.getForObject(path+"/device/"+ id +"?at=asILk9y2JB4bxh311DIKMr2Oaif1L6pn", String.class);
        return forObject;
    }
    /*
        http://127.0.0.1:8181/cxf/device?at=Jshb9jiOa4hi240POyOP58g4OHHBQ2sF
        添加设备 post 请求
     */
    @PostMapping("/addDevice")
    public String addDevice(@Valid Device device){
        Device body = restTemplate.postForEntity(path+"/device?at=asILk9y2JB4bxh311DIKMr2Oaif1L6pn",
                device, Device.class).getBody();
        return body.toString();
    }

    /*
        修改
     */
    @PutMapping("/updateDevice")
    public String updateDevice(@Valid Device device){
        restTemplate.put(path+"/cxf/device/"+ device.getId() +"?at=asILk9y2JB4bxh311DIKMr2Oaif1L6pn",device);
        return "修改成功";
    }

    /*
        删除
     */
    @DeleteMapping("/delDevice/{id}")
    public String delDevice(@PathVariable int id){
       restTemplate.delete(path+"/device/"+ id +"?at=asILk9y2JB4bxh311DIKMr2Oaif1L6pn");
        return "删除成功";
    }

postman请求参数配置

LZ用的是postman测试，顺便贴一下post请求和put请求的参数设置，用很多种形式，我这里只是随便选了一种

put请求

---

post请求

---

headers 设置，这里LZ2种请求都是一样
