如何在Spring REST中测试JWT过期？

import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.ActiveProfiles;
import import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

import java.util.Date;

@SpringBootTest
@AutoConfigureMockMvc
@ActiveProfiles("test")
public class JwtExpirationTest {

    @Autowired
    private MockMvc mockMvc;

    private String generateJwtToken() {
        long expirationTime = 1000; // 设置过期时间为1秒
        String secretKey = "yourSecretKey";
        Date now = new Date();
        Date expirationDate = new Date(now.getTime() + expirationTime);

        return Jwts.builder()
                .setSubject("testUser")
                .setIssuedAt(now)
                .setExpiration(expirationDate)
                .signWith(SignatureAlgorithm.HS256, secretKey)
                .compact();
    }

    @Test
    public void testExpiredJwtToken() throws Exception {
        String expiredJwtToken = generateJwtToken();

        mockMvc.perform(MockMvcRequestBuilders.get("/api/protected")
                .header("Authorization", "Bearer " + expiredJwtToken)
                .contentType(MediaType.APPLICATION_JSON))
                .andExpect(MockMvcResultMatchers.status().isUnauthorized());
    }
}
