对于Spring,传递给@Query注释的字符串的参数是否被视为纯数据,例如,如果您使用的是PreparedStatement类或任何旨在阻止SQL注入的方法?
final String MY_QUERY = "SELECT * FROM some_table WHERE some_column = ?1";
@Query(value=MY_QUERY, nativeQuery = true)
List<SomeEntity> findResults(String potentiallyMaliciousUserInput);

结论:上面的代码是否容易受到SQL注入的影响?
在默认配置中,Spring Webflux似乎将并行请求数限制为256.
我的设置有这个非常简单的控制器:
@RestController
public class SimpleRestController {
private final Log logger = LogFactory.getLog(getClass());
private AtomicLong countEnter = new AtomicLong(0);
private AtomicLong countExit = new AtomicLong(0);
@GetMapping(value = "/delayed")
public Mono<String> delayed() {
logger.info("delayed ENTER " + countEnter.incrementAndGet());
return Mono.just("result").delayElement(Duration.ofSeconds(60))
.doOnNext(s -> logger.info("delayed EXIT " + countExit.incrementAndGet()));
}
}

如何检索公钥以验证签名?
我只能从用户池中找到涵盖令牌的文档。因为我想处理未经身份验证的用户,所以这对我没有帮助。
我想知道:为什么这个代码导致了false
?当
Coz ==
运算符true
是相同的存储点时,它应该返回.
public static void main(String[] args) {
String a = new String("hello");
System.out.println(a == "hello");
