在Java中使用Calendar類來計(jì)算工作日可以通過以下方式實(shí)現(xiàn):
public int calculateWorkdays(Date startDate, Date endDate) {
Calendar startCal = Calendar.getInstance();
startCal.setTime(startDate);
Calendar endCal = Calendar.getInstance();
endCal.setTime(endDate);
int workdays = 0;
while (startCal.before(endCal) || startCal.equals(endCal)) {
if (startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SATURDAY && startCal.get(Calendar.DAY_OF_WEEK) != Calendar.SUNDAY) {
workdays++;
}
startCal.add(Calendar.DAY_OF_MONTH, 1);
}
return workdays;
}
@RestController
public class WorkdaysController {
@GetMapping("/workdays")
public ResponseEntity<Integer> calculateWorkdays(@RequestParam @DateTimeFormat(pattern = "yyyy-MM-dd") Date startDate,
@RequestParam @DateTimeFormat(pattern = "yyyy-MM-dd") Date endDate) {
int workdays = calculateWorkdays(startDate, endDate);
return ResponseEntity.ok(workdays);
}
}
關(guān)于RESTful API的安全認(rèn)證,可以使用Spring Security框架來實(shí)現(xiàn)??梢栽赟pring Boot應(yīng)用程序中添加Spring Security依賴項(xiàng),并配置安全認(rèn)證規(guī)則以保護(hù)API端點(diǎn)。
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/workdays").authenticated()
.anyRequest().permitAll()
.and()
.httpBasic();
}
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.inMemoryAuthentication()
.withUser("user").password(passwordEncoder().encode("password")).roles("USER");
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
以上是在Java中使用Calendar類來計(jì)算工作日和在RESTful API中實(shí)現(xiàn)安全認(rèn)證的簡單示例。要根據(jù)實(shí)際需求和項(xiàng)目規(guī)模進(jìn)行更詳細(xì)的配置和實(shí)現(xiàn)。
