我試圖創建一個Spring Rest Controller,我創建了一個像這樣的控制器。Spring 4.2.1 RestController試圖返回模板,而不是返回JSON
DeveloperRestController.java
@RestController
public class DeveloperRestController {
@RequestMapping("/developer/list")
public Developer index() {
Developer developer = new Developer("Developername", "[email protected]");
return developer;
}
}
的web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<filter>
<filter-name>sitemesh</filter-name>
<filter-class>org.sitemesh.config.ConfigurableSiteMeshFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>sitemesh</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!--Here we specify about the DispatcherServlet class in the Web Deployment Descriptor-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</context-param>
</web-app>
調度-servlet.xml中
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=" http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.2.xsd">
<context:component-scan base-package="com.developerdata.controller" />
<context:annotation-config />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
但它顯示未找到404頁,似乎春天試圖加載一個模板...
結果:
錯誤404 /WEB-INF/jsp/developer/list.jsp
我應該怎麼辦?
add' '。 –
你在classpath上有jackson嗎? –
你在classpath上有jackson嗎?你需要json jackson視圖解析器,jackson mapper以及添加mvc:註解驅動的3件東西。 –
