使用Spring MVC的Hibernate-validator组 [英] Hibernate-validator Groups with Spring MVC

问题描述

我正在使用hibernate-validator 4.3.1和Spring MVC 3.2.3。

I'm using hibernate-validator 4.3.1 and Spring MVC 3.2.3.

我的应用程序有一个带有以下属性和注释的bean（我是删除大部分内容使其变得简单）：

My application has a bean with the following properties and annotations (I've removed most of them to make it simple):

public class Account {
  @NotEmpty(groups = GroupOne.class)
  private String name;

  @NotEmpty(groups = GroupOne.class)
  private Date creationDate;

  @NotEmpty(groups = GroupTwo.class)
  private String role;

  @NotEmpty(groups = GroupTwo.class)
  private String profile;

  //getters and setters
}

因为它是显示，有两组验证，因为应用程序有一个向导形式，由两个步骤组成：第一步，name和creationDate字段由用户填写，第二步是角色和配置文件字段。

As it is showed, there are two groups of validations because the application has a wizard-form composed of two steps: in the first step the name and creationDate fields are filled by the user and in the second step the role and profile fields.

我添加一些Controller方法作为示例：

I add some Controller methods as example:

@RequestMapping(value = "/account/stepOne", method = "POST")
public String stepOne(@ModelAttribute @Validated(GroupOne.class) Account account, BindingResult bindingResult) {
  //Implementation
}

@RequestMapping(value = "/account/stepTwo", method = "POST")
public String stepTwo(@ModelAttribute @Validated(GroupTwo.class) Account account, BindingResult bindingResult) {
  //Implementation
}

上述方法指定必须由@应用哪些验证验证注释。

The above methods specify which validation has to be applied by @Validated annotation.

直到现在一切都好了很好，但是当我想以另一种形式重用那个bean时，我遇到了一些问题。此表单显示bean的所有字段，接收提交的控制器方法如下：

Until now everything works fine, but I have some problems when I want to reuse that bean in another form. This form displays all the fields of the bean and the controller's method which receives the submit is the following:

@RequestMapping(value = "/account/stepOne", method = "POST")
public String stepOne(@ModelAttribute @Validated Account account, BindingResult bindingResult) {
  //Implementation
}

如您所见，该组的名称已从@Validated注释中删除，因为我想应用定义的所有验证在Account bean中。

As you can see, the name of the group has been removed from the @Validated annotation because I want to apply all the validations defined in Account bean.

然而，它不起作用，使其工作的唯一方法是将默认组添加到bean的属性中，如下所示： / p>

However, it didn't work and the only way to make it work has been to add the Default group to the bean's properties, as so:

public class Account {
  @NotEmpty(groups = {GroupOne.class, Default.class})
  private String name;

  @NotEmpty(groups = {GroupOne.class, Default.class})
  private Date creationDate;

  @NotEmpty(groups = {GroupTwo.class, Default.class})
  private String role;

  @NotEmpty(groups = {GroupTwo.class, Default.class})
  private String profile;

  //getters and setters
}

有没有更优雅的方式来实现这个目标？

Is there a more elegant way to achieve this?

推荐答案

没有更优雅的方式。在不指定组的情况下进行验证将验证默认组。因此，您必须按照描述添加它。唯一的另一种选择是通过 @Validated（{GroupOne.class，GroupTwo.class}）显式验证您感兴趣的所有组。我想这是你喜欢的味道问题。

There is no more elegant way. Validating without specifying a group will validate the default groups. Hence you have to add it as described. The only other alternative is to explicitly validate all groups you are interested in via @Validated({GroupOne.class, GroupTwo.class}). I guess it is a matter of taste what you prefer.
