2、由于SpringBoot支持Restful风格处理,所以参数的接收可以采用路径参数的形式完成,但是需要在控制器方法的参数声明上使用@PathVariable注解与访问路径的参数进行关联。 代码语言:javascript 1packageorg.springboot.tentent.controller;23importorg.springframework.web.bind.annotation.PathVariable;4importorg.springframework.web...
Get started with Spring 5 and Spring Boot 2, through theLearn Springcourse: >> CHECK OUT THE COURSE 1. Overview In this quick tutorial, we’ll explore Spring’s@PathVariableannotation. Simply put,the@PathVariableannotation can be used to handle template variables in the request URI mapping, an...
Spring Boot @PathVariable tutorial shows how to read an URL template variable with @PathVariable annotation. We create a Spring Boot RESTful application to demonstrate the annotation. Spring is a popular Java application framework and Spring Boot is an evolution of Spring which helps create stand-...
