Question

我正在使用Dropwizard java示例实现HERE

我只用SQL server替换数据库进行了一次更改。通过在sql server中创建包含列的表，它也运行良好。

向localhost发布请求：3000 / auth / signup获取正确的数据。

AuthController.java：

 @Path("signup")
 @UnitOfWork
 @Consumes(MediaType.APPLICATION_JSON)
 @Produces(MediaType.APPLICATION_JSON)
 public Response signup(@Valid final User user, @Context final HttpServletRequest request)
  throws JOSEException {
  System.out.print(user);
  user.setPASSWORD(PasswordService.hashPassword(user.getPASSWORD()));
  final User savedUser = dao.save(user);
  final Token token = AuthUtils.createToken(request.getRemoteHost(), savedUser.getUSER_ID());
 return Response.status(Status.CREATED).entity(token).build();
 }

此处的帖子数据也是正确的，也是在userdao中检查的。

UserDAO.java：

  public User save(User user) {
    System.out.print(user);
    return persist(user);
 }

此处也更正数据。

User.java：

    @Entity
    @Table(name = "TBLLOGINUSER")
    @NamedQueries({
    @NamedQuery(name = "User.findAll", query = "SELECT u FROM User u"),
    @NamedQuery(name = "User.findByEmail", query = "SELECT u FROM User u WHERE u.USER_NAME = :email")
   })
  public class User {

   @Id
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   private Long USER_ID;

   @Email
   @Column(name = "USER_NAME")
   private String USER_NAME;

   @Column(name = "PASSWORD")
   private String PASSWORD;

   @Column(name = "LAST_LOGIN")
   private String LAST_LOGIN;

   @Column(name = "STATUS")
   private String STATUS;


   public Long getUSER_ID() {
    return USER_ID;
    }
   public String getUSER_NAME() {
    return USER_NAME;
   }
   public String getSTATUS() {
    return STATUS;
    }

    public String getLAST_LOGIN() {
    return LAST_LOGIN;
    }
    @JsonIgnore
    public String getPASSWORD() {
    return PASSWORD;
   } 

     public void setUSER_NAME(final String email) {
     this.USER_NAME = email;
    }
    public void setPASSWORD(final String password) {
    this.PASSWORD = password;
   }

    public void setLAST_LOGIN(final String name) {
    this.LAST_LOGIN = name;
   }
   public void setSTATUS(final String name) {
    this.STATUS = name;
     }
    public void setUSER_ID(final Long name) {
   this.USER_ID = name;
   } 
   @JsonIgnore
    public int getSignInMethodCount() throws IllegalArgumentException,IllegalAccessException,
  NoSuchFieldException, SecurityException {
   int count = 0;

    if (this.getPASSWORD() != null) {
  count++;
   } return count;
   }

    }

但是日志记录就是这样的。

知道为什么将空值发送到db ????

Hibernate将空值发送到数据库表
