When I run this application everything looks fine but I can't see the POST/PUT/or DELETE. I try to many things I find from Internet but it doesn't work. I new on this topic. I actually want to wrote null inputs and get exceptions for exception handling.

So your Docket Configuration has specified a regex pattern for product
#Bean
public Docket productApi() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.basePackage("example.com"))
.paths(regex("/product.*"))
.build()
.apiInfo(metaData());
}
But your controllers don't have any APIs with /product.
Thus you're not able to see APIs in swagger documentation.
Try with below configuration and see if it shows you all endpoints and then start working around regex configurations.
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build();
}
Above configuration matches all the API paths in your web application basically anywhere.
You can access your APIs at
Change the APPLICATION_PORT and CONTEXT-PATH
http://localhost:{{APPLICATION_PORT}}/{{CONTEXT-PATH}}/swagger-ui.html

How can ı fix this problem . Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException: Cannot invoke "org.springframework.web.servlet.mvc.condition.PatternsRequestCondition.getPatterns()" because "this.condition" is null .

No operations defined in spec!! and 404 error in postman. The spring boot don't show any error from my code. yet i can't establish the connection

This is a simple code that i got from youtube for practice. well i did the code correcly but i cant get the explicit mapping correclty, that what the 404 error in the postman says.
I don't know if its my Spring boot app problem or the code error. please have a look at this , Since spring boot is not giving a proper answer.

The issue is due to dependency conflict, spring-boot-starter-data-jpa dependency is enough, because hibernate-core 5.X.X Final version is included.
From the above image I hope you understood the issue,
Solution:
Removed unwanted dependencies and resolved the conflict

Did you read the CORS Support section in Spring Documentation?
You can also try to use Spring Higher-Order Components and #EnableCORS or if you don't want to use additional dependency use #Bean from here

You need to configure a web cross-domain configuration as follows:
package com.liukai.routermanagement.config;
import com.liukai.routermanagement.interceptor.LoginHandlerInterceptor;
import org.springframework.boot.SpringBootConfiguration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
#SpringBootConfiguration
public class MyWebMvcConfig extends WebMvcConfigurationSupport {
#Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LoginHandlerInterceptor()).addPathPatterns("/**").excludePathPatterns("/user/login","/router/login","/user/registered");
super.addInterceptors(registry);
}
// this main mothod，Just add this method
#Override
protected void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("*").allowCredentials(true).allowedMethods("GET","POST","PUT","DELETE");
super.addCorsMappings(registry);
}
}
