Spring Boot验证:如何测试DTO对象

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.validation.beanvalidation.LocalValidatorFactoryBean;

import javax.validation.ConstraintViolation;
import javax.validation.Validator;
import java.util.Set;

@SpringBootTest
public class DtoValidationTest {

    private Validator validator = new LocalValidatorFactoryBean();

    @Test
    public void testDtoValidation() {
        // 准备测试数据
        SampleDto sampleDto = new SampleDto();
        sampleDto.setName("John Doe");
        sampleDto.setAge(25);

        // 进行验证
        Set<ConstraintViolation<SampleDto>> violations = validator.validate(sampleDto);

        // 检查验证结果
        assert violations.isEmpty() : "DTO对象验证失败";

    }
