PathVariable请求路径

@PathVariable是用来获取请求路径中参数的值的注解。它适用于restful风格的URL请求路径。比如，如果我们有一个请求路径是http://localhost:8806/mybatisDemo/detail/1，其中的1就是参数id的值。通过在方法上使用@GetMapping("/detail/{id}")注解，并在方法的参数上使用@PathVariable注解，我们可以获取到这个参数的值。例如：
@GetMapping("/detail/{id}")
public ApiResponse getApplicationById(@PathVariable Long id){
// 根据id查询数据
PubTest pubTest = mybatisDemoService.getById(id);
return success(pubTest);
}
在这个例子中，@PathVariable注解将会获取到路径中的id参数的值，然后我们可以使用这个值进行相关的业务处理。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
