首先我要禁告各位，Spring发展过程中，每个版本都有一定差异。如果你做实验失败后在网上搜索答案，切记看一下版本号还有文章帖子的发布时间。否则你可能按照Spring3配置方法去Spring4。
@RestController 默认返回 @ResponseBody， 所以@ResponseBody可加可不加
Maven 增加 jackson 开发包
<dependency> <groupId>com.fasterxml.jackson.dataformat</groupId> <artifactId>jackson-dataformat-xml</artifactId> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> </dependency>
url-pattern匹配中增加*.xml跟*.json
<servlet>
<servlet-name>springframework</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springframework</servlet-name>
<url-pattern>/welcome.jsp</url-pattern>
<url-pattern>/welcome.html</url-pattern>
<url-pattern>*.json</url-pattern>
<url-pattern>*.xml</url-pattern>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
