[英]Spring boot annotation validation set custom field name
In my spring boot rest application I'm doing validation via annotation and has the following class, how do I set a custom field name for the fields and use them in the error messages, the below example works, I can retrieve the value from the JSON payload and include them in the error message.在我的spring boot rest应用程序中,我通过注释进行验证并具有以下类,如何为字段设置自定义字段名称并在错误消息中使用它们,下面的示例有效,我可以从JSON 有效负载并将它们包含在错误消息中。
I need to set the name of the field to 'E-mail address' so I can put it in the error message.我需要将该字段的名称设置为“电子邮件地址”,以便将其放入错误消息中。
The application also does not have any forms, input is received from json.该应用程序也没有任何表单,输入是从 json 接收的。
public class Contact {
@Size(max = 20, message = ErrorMessages.INVALID_LENGTH)
private String email;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
public class ErrorMessages {
public static final String INVALID_LENGTH = "'${validatedValue}' must be between {min} and {max} characters long";
}
EDIT:编辑:
JSON input JSON 输入
{
"email": "tesaaaaaaaaaaaaaaaaaaaaaaaaaaaat@test.com"
}
expected output:预期输出:
{
"timestamp": "2022-06-13T00:32:28.861+00:00",
"status": 400,
"errors": [
"E-mail address must be between 0 and 20 characters long"
]
}
I don't want to hard code the field name in the error message since I want to reuse it on other fields for checking their length.我不想在错误消息中对字段名称进行硬编码,因为我想在其他字段上重用它来检查它们的长度。 I want to do something similar to ${validatedValue} but with the name instead.
我想做一些类似于 ${validatedValue} 但使用名称的事情。
UPDATE:更新:
Ok seems that setting a 'label' on a field to use in interpolation is not possible, I just created a class that contains the display names that I want to use and appended the error message to it:好的,似乎不可能在字段上设置“标签”以用于插值,我刚刚创建了一个包含我要使用的显示名称的类,并将错误消息附加到它:
public class FieldName {
public static final String E_MAIL_ADDRESS = "E-mail address";
}
public class ErrorMessages {
private static final String INVALID_LENGTH = " '${validatedValue}' must be between {min} and {max} characters long";
public static final String E_MAIL_INVALID_LENGTH = FieldName.E_MAIL_ADDRESS + INVALID_LENGTH;
}
The payload class有效载荷类
public class Contact {
@Size(max = 20, message = ErrorMessages.E_MAIL_INVALID_LENGTH)
private String email;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
Fixed output:固定输出:
{
"timestamp": "2022-06-13T03:27:03.207+00:00",
"status": 400,
"errors": [
"E-mail address 'tesaaaaaaaaaaaaaaaaaaaaaaaaaaaat@test.com' must be between 0 and 20 characters long"
]
}
