Question

我正在尝试使用带有添加的restcontroller功能的spring 4创建一个spring mvc rest app但是我在restcontrollerclass中得到了一个错误，我无法解决。

我得到的错误就是这个

我无法导入org.springframework.web.bind.annotation.RestController;在我的restcontroller课程中，它下方标有红线。我有所有正确的罐子

Restcontroller

import org.springframework.web.bind.annotation.RequestMapping;

this is the line that is marked with a red line underneath
import org.springframework.web.bind.annotation.RestController;
if i remove the annotaion @Restcontroller the error disapears
so how do i import org.springframework.web.bind.annotation.RequestMapping; without      getting an error

[code] 
@RestController
@RequestMapping(value="/testrest")
public class RestController {

@RequestMapping("/greeting")
public String greeting(){
    return "hello";
}
}
[/code]

Answer 1

将其包含在您的Pom中：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>${org.springframework.version}</version>
</dependency>

让我知道你是怎么走的。

Answer 2

@RestController和你的类名（RestController）是冲突的。您不能在班级中使用相同的名称。更改类文件的名称。它应该工作。
