@Controller和@RestController

@RestController=@Controller+@ResponseBody

1. Use RestController, return to the front of the content is Return the contents can not be returned jsp / html page, etc.,

In this case, application-spring.xml profile, does not require configuration view resolver

1  <!-- 3.配置jsp 显示ViewResolver -->
2 <bean id="viewResolver"
3           class="org.springframework.web.servlet.view.UrlBasedViewResolver">
4         <property name="viewClass"
5                   value="org.springframework.web.servlet.view.JstlView" />
6         <property name="prefix" value="/WEB-INF/jsp/" />
7         <property name="suffix" value=".jsp" />
8 </bean>

NOTE: view resolver will return control layer according to parse the string, if it was return "hello", after the parser will automatically add the prefix and suffix into /WEB-INF/view/hello.jsp.

2. To return to the specified page, @Controller may be used, with the above view resolver, if necessary to return JSON, XML or custom mediaType content to a page, you need to add annotations on @ResponseBody corresponding method.
