Required URI template variable 'id' for method parameter type Long is present but converted to null
时间: 2024-05-22 12:12:51 浏览: 634
As an AI language model, I don't have much context to work with. However, this error message typically indicates that a required variable in a URL template is missing or null. In this case, the variable is 'id' and it is expected to be of type Long. It's possible that the variable was not passed in the URL or was not properly converted to a Long data type. You may need to review the code and ensure that the necessary variable is being passed and properly formatted.

根据引用\[1\]和引用\[2\]的内容,你遇到的问题是在调用接口路径时,缺少了必需的URI模板变量。具体来说,你使用了@PathVariable注解修饰的参数,但是在路径中没有包含该变量,导致出现了"Required URI template variable 'companyId' for method parameter type Long is not present"的错误信息。要解决这个问题,你需要确保路径中包含了该变量,并正确使用@PathVariable注解将URL中的占位符参数绑定到控制器处理方法的入参中。

Required URI template variable 'id' for method parameter type String is not present
这个错误通常是因为你的代码中使用了一个需要 URI 中包含特定变量的请求,但是在实际的请求中并没有包含该变量。你需要检查一下你的代码中是否有使用了 `@PathVariable` 注解来获取 URI 中的变量值,并且检查一下请求的 URI 是否确实包含了对应的变量值。
例如,如果你的代码中有以下方法:
```java
@GetMapping("/users/{id}")
public User getUserById(@PathVariable String id) {
// ...
}
```
那么你发送的请求的 URI 必须包含一个名为 `id` 的变量,例如:
```
GET /users/123
```
其中的 `123` 就是 `id` 变量的值。如果请求中没有包含这个变量,就会出现类似 "Required URI template variable 'id' for method parameter type String is not present" 的错误提示。
