导入org.springframework.web.bind.annotation.RestController无法解析

Question

我正在使用Eclipse Kepler ..我试图使用import org.springframework.web.bind.annotation.RestController但是这个import语句没有得到解决我已经添加了所需的所有依赖项..但是restcontroller没有得到解决..

package s;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class RestController {



@Autowired Bean bean;
@RequestMapping(value="/springAngularJS", method=RequestMethod.GET)

public @ResponseBody Bean getBean() {      
Bean bean=new Bean();
    bean.setUserName("savitha");

    bean.setAge("22");

    bean.setCompany("Infosys");

    bean.setDesignation("ApplicationDeveloper");

    return bean;
  }
  }

提前致谢..

Answer 1

问题是您的类被命名为"RestController",并且与用于注释的实际RestController类冲突.您只需要将类/文件重命名为"DemoController"之类的其他内容以避免类名冲突或指定完整路径,如@ org.springframework.web.bind.annotation.RestController,以便它知道使用哪一个

Answer 2

@RestController 注解自 spring-web 4.0

Answer 3

我遇到了同样的问题，在这里找到了解决方案。将此依赖项添加到pom.xml

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>
