In Go, method overriding allows methods in a base class to be redefined in a derived class while keeping the same method signature: use the override keyword. The overridden method must have the same signature as the base method. The receiver type of the overridden method must be a subtype of the base type.

Practical practice of Nginx rewriting URL configuration, optimizing website structure and SEO Introduction: In the modern Internet era, traditional static web pages can no longer meet the needs of users. In order to provide a better user experience, many websites begin to use dynamic web technology. However, the URLs of dynamic web pages are often not friendly enough, and there are certain difficulties in being included by search engines and shared by users. This article will introduce how to use Nginx's URL rewriting function to optimize the website structure and SEO. 1. Nginx’s URL rewriting function Nginx

Nginx is a lightweight, high-performance web server that not only supports advanced functions such as reverse proxy and load balancing, but also has powerful request rewriting capabilities. In actual web applications, in many cases the request URL needs to be rewritten to achieve better user experience and search engine optimization effects. This article will introduce how Nginx implements request rewriting configuration based on the request URL, including specific code examples. Rewrite syntax In Nginx, you can use the rewrite directive to perform request rewriting. its basic language

Differences: 1. MySQL is a relational database, while NoSQL is non-relational. 2. MySQL’s strict mode restrictions are not easy to expand, while NoSQL is easy to expand. 3. MySQL requires a detailed database model before creating a database, which is not required in NoSQL. 4. MySQL provides a large number of reporting tools, but nosql does not. 5. Compared with MySQL, NoSQL provides a more flexible design. 6. The standard language used in MySQL is SQL, while NoSQL lacks a standard query language.

The equals(Object) method in Java is a method used to compare two objects for equality. In Java classes, the equals method is inherited from the Object class by default, and it simply compares the reference values ​​of two objects. However, we often need to compare objects for equality in a custom way, which requires overriding the equals method in a subclass. In order to correctly compare objects for equality, we must follow several rules. First of all, the equals method must satisfy reflexivity, that is to say

The difference between Overload and Override Overload means that there can be multiple methods with the same name in the same class, but the parameter lists of these methods are different, that is, the parameter parameters or parameter types are different. Of course, the return value can be different during overloading, but if the parameter list is completely consistent, overloading cannot be achieved through inconsistent return types. This is not allowed. Overriding means that the method name and parameters in the subclass can be exactly the same as those in the parent class. When this method is called through an object created by the subclass, the method defined in the subclass will be called, that is, the method in the subclass. The method overrides the method of the parent class. When a subclass overrides a parent class method, it can only throw fewer or smaller exceptions than the parent class. Overridden method

The access modifiers of overridden methods in subclasses must be the same or broader: subclass methods can have broader access rights than parent class methods (for example, from protected to public). The access permissions of subclass methods cannot be more restricted than the parent class methods (for example, changed from public to protected).
