如何在spring boot中使用regex输入字段进行验证

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

import javax.validation.constraints.Pattern;

public class MyDTO {
    @Pattern(regexp = "正则表达式", message = "错误消息")
    private String inputField;

    // getter and setter
}

import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import javax.validation.Valid;

@RestController
public class MyController {
    @PostMapping("/validate")
    public String validateInput(@Valid @RequestBody MyDTO myDTO, BindingResult bindingResult) {
        if (bindingResult.hasErrors()) {
            // 处理验证错误
            return "验证失败";
        }
        
        // 验证通过，执行其他操作
        return "验证成功";
    }
}
