在運行Spring Restful web服務時沒有Spring Boot的問題

Question

我正在嘗試構建Restful Web服務。我的Maven項目名稱是其他我正在關注Spring's Building a RESTful Web Service這樣做，但我不想使用Spring Boot，只是創建一個war並將其託管在我的eclise/STS的Tomcat中。這裏是我的web.xml和XX-servlet.xml的文件：

的web.xml

<web-app> 
    <display-name>Archetype Created Web Application</display-name> 

    <!-- The front controller of this Spring Web application, responsible for handling all application requests --> 
    <servlet> 
     <servlet-name>rest</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <!-- Map all requests to the DispatcherServlet for handling --> 
    <servlet-mapping> 
     <servlet-name>rest</servlet-name> 
     <url-pattern>/*</url-pattern> 
    </servlet-mapping> 
</web-app> 

休息-servlet.xml中

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

     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 

     <context:annotation-config /> 
     <context:component-scan base-package="com.rest" /> 
     <mvc:annotation-driven/> 


</beans> 

GreetingController.java

@RestController 
public class GreetingController2 { 
    private final AtomicLong counter = new AtomicLong(); 

    @RequestMapping("/greeting") 
    public Greeting greeting(@RequestParam(value = "name", defaultValue = "World") String name) { 
     return new Greeting(counter.incrementAndGet(), String.format("Hello %s", name)); 
    } 
} 

當我在Tomcat上運行此URL時：http://localhost:8080/rest給出了404，我在tomcat控制檯Aug 16, 2017 3:59:28 PM org.springframework.web.servlet.PageNotFound noHandlerFound WARNING: No mapping found for HTTP request with URI [/rest/] in DispatcherServlet with name 'rest' 中看到此消息，而我確實有映射。

而當我點擊http://localhost:8080/rest/greeting時，我得到http 406，消息The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.，而根據教程，它應該轉換爲JSON，它可以在瀏覽器中呈現。

我花了很多時間試圖弄清楚，看着SO上的各種帖子，以找出什麼是錯的，但不能。

Answer 1

你不必像
@RequestMapping（「/」）
根據您的代碼默認映射你上面應該有以下網址做工精細
http://localhost:8080/rest/greeting
