Spring roo：无法更新由 PhpMyAdmin 插入的用户数据

【问题标题】：Spring roo: Cannot update user data which was inserted by PhpMyAdminSpring roo：无法更新由 PhpMyAdmin 插入的用户数据
【发布时间】：2013-05-08 13:44:28
【问题描述】：

我使用 spring roo 构建了一个 CMS webapp。

这个应用当然有用户管理功能。

我的问题是，如果我使用 PhpMyAdmin 将用户信息插入数据库，然后转到我的应用程序来修改这些信息，则会出现错误。 （如果我按应用插入用户信息并按应用编辑，它工作正常）

你们中的任何人都可以向我解释为什么会发生这种情况以及如何解决它吗？

非常感谢。

Addition info: 这个错误或者只有user表出现，其他表（如news或product）没有问题。 下面是我的一些代码。

EndUser.java（实体）

public class EndUser {

    @NotNull
    @Size(min = 1, max = 20)
    @Column(name = "user_id", unique = true, nullable = false)
    private String userId;

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

    @NotNull
    @Size(min = 1, max = 40)
    @Column(name = "password", nullable = false)
    private String password;

    @Column(name = "first_name")
    private String firstName;

    @Column(name = "last_name")
    private String lastName;

    @Column(name = "gender")
    private Integer gender;

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

    @Column(name = "last_login")
    @DateTimeFormat(style = "M-")
    private Date lastLogin;

    @Column(name = "created_date")
    @DateTimeFormat(style = "M-")
    private Date createdDate;

    @Column(name = "date_of_birth")
    @DateTimeFormat(style = "M-")
    private Date dateOfBirth;

    @NotNull
    @Column(name = "role")
    private String role;

    @Column(name = "is_deleted")
    private Boolean isDeleted;
}

EndUserController.java

@PreAuthorize("hasRole('ROLE_SUPER_ADMIN')")
@RequestMapping(method = RequestMethod.PUT, produces = "text/html")
public String update(@Valid EndUser endUser, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest) {
    if (bindingResult.hasErrors()) {
        populateEditForm(uiModel, endUser);
        return "admin/user/update";
    }

    endUser.setIsDeleted(false);

    uiModel.asMap().clear();
    endUser.merge();
    return "redirect:/admin/user/" + encodeUrlPathSegment(endUser.getId().toString(), httpServletRequest);
}

如果我更新了由 PhpMyAdmin 插入的用户信息，则会出现错误

【问题讨论】：

  • 表/对象上是否有版本列/字段？
  • 是的，版本字段在 EndUser_Roo_Entity.aj 中管理

标签： hibernate spring-roo


【解决方案1】：

开箱即用的 Hibernate 设置为不支持直接修改表。这是因为 Hibernate 在读/写之间缓存了实体。如果你一遍又一遍地请求同一个对象，如果 Hibernate 正常工作，它应该读取一次对象，对缓存进行所有更新，并且只有在缓存过期时才写入对象。

如果您在 Hibernate 之后修改 DB，则 Cache 中的项目与 DB 中的项目不匹配。有一种方法可以在 Hibernate 中关闭它，但它会影响性能。不幸的是，自从我不得不在 Hibernate 中执行此操作以来已经有一段时间了，所以您实际上是如何执行此操作的，我不能 100% 确定。您可能需要花一些时间在谷歌上搜索它。

【讨论】：

  • 我无法解释为什么直接插入一个表而不是另一个表。我可以说，默认情况下，Hibernate 期望控制数据库中的数据。我知道这一点是因为我们在将 Hibernate 连接到从另一个应用程序插入的 DB2 数据库时遇到了同样的问题。我记得必须将 Hibernate 配置为关闭二级缓存，因为当它下面的某些内容发生变化时，它往往会自行呕吐。我相信，当配置为允许外部插入时，Hibernate 使用版本列来检测更改冲突。
  • 很好的解释。谢谢你的建议。我会尝试关闭二级缓存并尽快报告结果。
  • 这是我非常丑陋的错误。我在 excel 文件和工作表新闻（或产品）中创建了数据我已经为列版本输入了一个整数值，但是在工作表用户中，“版本”列没有值，因此休眠将尝试保留我的对象而不是更新它.
