@Query 和存储库中的错误

可能有错误@Query由于我的实体有关系？ 存储库包含错误。

创建名称为“clickRepository”的 bean 时出错：调用 init 方法失败；嵌套异常是java.lang.IllegalArgumentException： 方法公共摘要查询验证失败 java.lang.String com.qoobico.remindme.server.repository.ClickRepository.sent(java.lang.String,long)！

控制器

 @Autowired
private ClickService service;

/*
    i.e. information about fullname_client, id_banner sent to server from client
*/
@RequestMapping(value = "/sentemail", method = RequestMethod.POST)
@ResponseBody
public String sentClick(@RequestParam ("fullnameClient") String fullnameClient,@RequestParam ("idbanners") long idbanners) {

    return service.sent(fullnameClient, idbanners);
}

存储库

@Query("SELECT c.fullnameClient FROM Click AS c join c.idBanner Banners b WHERE b.idBanner = :idbanners AND c.fullnameClient = :fullnameClient")
String sent(@Param("fullnameClient") String fullnameClient, @Param("idbanners") long idbanners);

实体点击

@Id
@Column(name = "id_click", unique = true, nullable = false)
@GeneratedValue(generator = "increment")
@GenericGenerator(name = "increment", strategy = "increment")
private long idClick;

@ManyToOne(fetch = FetchType.EAGER, cascade = {CascadeType.MERGE, CascadeType.PERSIST})
@JoinColumn(name = "id_banners", nullable = false)
private Banners idbanners;

@Column(name = "fullname_client", nullable = false, length = 50)
private String fullnameClient;

实体横幅

@Id
@Column(name = "id_banner", unique = true, nullable = false)
@GeneratedValue(generator = "increment")
@GenericGenerator(name = "increment", strategy = "increment")
private long idBanner;

@OneToMany(fetch = FetchType.EAGER, mappedBy = "banners")
private Set<Businessbanner> businessbanners;

@OneToMany(fetch = FetchType.EAGER, mappedBy = "idbanners")
private Set<Click> clicks;

您的参数名称不同。尝试这个：

 @Query("SELECT c.fullnameClient FROM Click AS c join c.idbanners b WHERE b.idBanner = :idbanners AND c.fullnameClient = :fullnameClient")

    String sent(@Param("fullnameClient") String fullnameClient, @Param("idbanners ") long idbanners);

Update

好吧，你的加入是错误的..而不是 c 加入 c.IdBanner.. 它应该是 c.idbanners。
