Spring doesn't validate JSON request-CodePudding

When I send the request:

"Person": {
   "name": 5
 }

The request should fail (bad request) because 5 isn't a String. It prints: Person{name='5'}.

Similarly, there's no error when I send null.

I have these annotations:

@JsonProperty("name")
@Valid
@NotBlank
private String name;

Controller:

public void register(@Valid @RequestBody Person p) {
    ...
}

How can I make it validate the name so only strings are accepted?

CodePudding user response：

Add a BindingResult parameter.

public void register(@Valid @RequestBody Person p, BindingResult result) {
    if (result.hasErrors()) {
        // show error message
    }
}

Use the @Pattern annotation.

@JsonProperty("name")
@Valid
@NotBlank
@Pattern(regexp="^[A-Za-z]*$", message = "Name should contains alphabetic values only")
private String name;
