实操

概念啥的玩意自己网上百度自己查

引入pom

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-hateoas</artifactId>
        </dependency>

编写bean

@Data
public class UserVo extends RepresentationModel<UserVo> implements Serializable {
    private final String name;
    @JsonCreator
    public UserVo(@JsonProperty("name") String name) {
        this.name = name;
    }
}

编写controller

@RestController
@RequestMapping("user")
public class UserController {

    @GetMapping("get")
    public Object user(){
        UserVo userVo = new UserVo("张三");
        //添加自身地址信息
        userVo.add(linkTo(methodOn(UserController.class).user()).withSelfRel()).
                //添加额外地址信息
                add(linkTo(methodOn(UserController.class).info(1L)).withRel("info"));
        return userVo;
    }
    @GetMapping("info/{id}")
    public Object info(@PathVariable Long id){
        return "info"+id;
    }
}
