我有以下控制器

@RestController("/person")
public class PersonController {

    @Autowired
    PersonService personService;

    @RequestMapping(value = "/list",
                    method = RequestMethod.GET,
                    produces = MediaType.APPLICATION_JSON_VALUE
                    )
    public List<PersonNode> getPersons(){

        return personService.getList();

    }

}

现在春天neo4j配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

    <!-- Scan the JavaConfig -->

    <context:annotation-config/>
    <context:component-scan base-package="server.infrastructure.repositories.neo4j.config" />

</beans>

和spring mvc rest config：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"

                    http://www.springframework.org/schema/mvc
                    http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--Used for Spring MVC configuration - must have-->
    <mvc:annotation-driven />

    <!-- This shows where to scan for rest controller -->
    <context:component-scan base-package="server.api.rest.controller" />

</beans>

和web.xml 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         version="3.1">

</web-app>

然而，当我提到http://localhost:8080/rest/person/list时，我一直得到：

使用我的Tomcat启动日志：

但是，当我提到http://localhost:8080/rest/list时，我会得到预期的人员名单。

我希望在课堂级别的人员使用http://localhost:8080/rest/person/list时引用@RestController和`list＆＃39;在方法层面。如何做到这一点？

您应该将@RequestMapping添加到Controller类

@RestController
@RequestMapping("/person")
public class PersonController {

   @Autowired
   PersonService personService;

   @RequestMapping(value = "/list", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
   public List<PersonNode> getPersons(){
     return personService.getList();
   }
}
