在Java开发领域,Quarkus是一个近年来备受瞩目的框架,它被誉为“Kubernetes原生的Java框架”。Quarkus旨在通过利用JVM的即时编译(JIT)和先进的AOT(Ahead-of-Time)编译技术,为微服务和云原生应用带来超低的启动时间和内存占用。本文将深入浅出地介绍Quarkus的核心特性、常见问题、易错点及避免策略,并附上实用的代码示例。
大多数开发者对HTTP Status Code都比较熟悉，所以看到这些code就大致明白什么意思，当然对应用开发者也有严格的要求，你千万别将404解释为内部错误，如数据库连接失败这样的，逆正常思维的事情不要做。HTTP status code归类如下，当然你也可以参考一下 HTTP Status Codes Cheat Sheet[2]。Informational responses (100–...
Let’s take a look at a couple of examples and see what our functional code examples using streams would look like. Exercise 1: Get the unique surnames in uppercase of the first 15 book authors that are 50 years old or older. So you know, the source of our stream, library, is an ...
There are two main approaches to choosing the collection type you need in your code. The first is simple enough, but not always the most effective: if it fits into an ArrayList, use ArrayList, otherwise you probably need a HashMap. The other includes having an understanding of the operations...

方法: MongoDB中的集合查询(获取一组文档中某个字段的不同值列表) 运用方法:DBCollection对象方法中的 distinct() 语句: 语句结构:distinct(key,[query]) key字符串,指定获取哪个字段的不同值;query:包含标准查询选项的对象,指定了要从哪个文档中获取不同的字段值 ...
OWASP: Query Parameterization Cheat Sheet 潜在的sql/JDOQL注入(JDO) 漏洞特征:SQL_INJECTION_JDO 输入进sql查询的数据应该通过严格的检查。在预编译中绑定参数可以更容易的缓解sql注入带来的危害。 有漏洞的代码: PersistenceManager pm = getPM(); Query q = pm.newQuery("select * from Users where name = ...
Java Unmarshaller Security - Turning your data into code execution 在反序列化漏洞中被利用的类 漏洞特征:DESERIALIZATION_GADGET 反序列化利用链是一些可以被攻击者利用的类,这些类通常存在于远程api中。这些类也会被添自定义行为,目的是用readObject方法去反序列化 (Serializable)或者调用来自序列化对象中的方法(Inv...

Robust code means excellent exception handling. We’ve outlined the basics of try-catch-finally blocks, the difference between checked and unchecked exceptions, and even touched on more advanced concepts like custom exceptions and the try-with-resources statement introduced in Java 7. 健壮的代码意味...
