我有兩個java models球員和球隊。我有一個控制器類。當(dāng)我從用戶界面通過 ajax 發(fā)送發(fā)布請求時出現(xiàn)錯誤。我已經(jīng)解決了類似的錯誤CORS。但是有一個錯誤我無法解決；knockout.js沒有發(fā)生調(diào)試錯誤和發(fā)布請求。我的數(shù)據(jù)庫沒有變化。我共享了模型類、控制器類、html 和javascript文件。我需要改變什么？你能幫忙嗎？播放器模型@Entity@Table(name = "player")public class Player{ @Id @GeneratedValue @NotNull @Column private int id; @NotNull @Column private String playerName; @NotNull @Column private String playerSurname; @Column private int playerAge; public String getPlayerName() { return playerName; } public void setPlayerName(String playerName) { this.playerName = playerName; } public String getPlayerSurname() { return playerSurname; } public void setPlayerSurname(String playerSurname) { this.playerSurname = playerSurname; } public int getId() { return id; } public void setId(int id) { this.id = id; } public int getPlayerAge() { return playerAge; } public void setPlayerAge(int playerAge) { this.playerAge = playerAge; }}團(tuán)隊模型@Entity@Table(name = "team")public class Team { @Id @GeneratedValue @NotNull @Column private int id; @NotNull @Column private String teamName; @Column private String teamCountry; public Team(){ } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getTeamName() { return teamName; } public void setTeamName(String teamName) { this.teamName = teamName; } public String getTeamCountry() { return teamCountry; } public void setTeamCountry(String teamCountry) { this.teamCountry = teamCountry; } @ManyToOne private Player player; public Player getPlayer() { return player; } public void setPlayer(Player player) { this.player = player; }}

回答你的問題，它沒有做任何事情，因為你沒有發(fā)送參數(shù) Player （必須有效），因為你使用的是表單，這不是你應(yīng)該這樣做的方式。（請求參數(shù)通過 url 發(fā)送，你的表單應(yīng)該通過 @RequestBody 發(fā)送）
我會做這樣的事情：
在我的控制器上，由于我只能有一個@RequestBody，但是我的表單發(fā)送了一個包含多種類型對象數(shù)據(jù)的對象，我會做一個Dto
是這樣的：
@PostMapping(value="/createNewTeam")
? ? public Team createNewTeam(@Valid @RequestBody PayloadDto payloadDto) {
? ? ? ? final Player player = new Player();
? ? ? ? player.setPlayerName(payloadDto.playerName);
? ? ? ? // fill player information
? ? ? ? final Team team = new Team();
? ? ? ? // fill team information...?
? ? ? ? playerRepository.save(player);
? ? ? ? return teamRepository.save(team);
? ? }
您的 PayloadDto 對象必須包含您發(fā)送的所有屬性。
public class PayloadDto{
? @JsonProperty("playerName")
? public String playerName;
? @JsonProperty("playerSurname")
? public String playerSurname;
? // .. more player and team properties?
}
確保 jsonProperty("propertyName) 與您在發(fā)送信息時使用的名稱相同
