我试图用springboots创建获取请求,但是我可以获取所有用户请求,但是我想通过姓氏发出获取请求。 所以我尝试使用@requestparam,但是它没有显示任何信息。 我真的不知道该怎么解决
用户
public class User {
private String name;
private String lastname;
private String email;
public User(String name, String lastname, String email) {
super();
this.name = name;
this.lastname = lastname;
this.email = email;
}
public String getName() {
return name;
}
public String getLastname() {
return lastname;
}
public String getEmail() {
return email;
}
public void setName(String name) {
this.name = name;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return String.format("User[name=%s,lastname=%s,email=%s]", name, lastname, email);
}
}
UserService
@Component
public class UserService {
private static List<User> users =new ArrayList<>();
static {
users.add(new User("jj","kim","kk@gmail.com"));
users.add(new User("cc","smith","cc@gmail.com"));
users.add(new User("ss","jake","ss@gmail.com"));
}
public List<User>findAll(){
return users;
}
public User save(User user){
users.add(user);
return user;
}
public User findByLastName(String lastname){
for(User user:users){
if(user.getLastname()==lastname){
return user;
}
}
return null;
}
}
UserData
@RestController
public class UserData {
@Autowired
private UserService service;
@GetMapping("/users")
public List<User> getAllUsers(){
return service.findAll();
}
@GetMapping("/users/{lastname}")
public List<User> getUser(@RequestParam(value ="lastname", required = true)String lastname){
return service.findByLastName(lastname);
}
}
