使用内容协商实现多视图例根据前篇文件的介绍，这里直接给出例子
配置xml <context:component-scan base-package="com.controls" />
<context:annotation-config />
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="order" value="1" /> <property name="favorParameter" value="false" /> <property name="ignoreAcceptHeader" value="true" />
<property name="mediaTypes"> <map> <entry key="json" value="application/json" /> <entry key="xml" value="application/xml" /> </map> </property>
<property name="defaultViews"> <list> <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"></bean> <bean class="org.springframework.web.servlet.view.xml.MarshallingView"> <constructor-arg> <bean class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="classesToBeBound"> <list> <value>com.model.User</value> </list> </property> </bean> </constructor-arg> </bean> </list> </property> </bean> <!-- 上面没匹配到则会使用这个视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="order" value="2" /> <property name="prefix" value="/WEB-INF/views/" /> <property name="suffix" value=".jsp" /> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> </bean>
Model
@XmlRootElement public class User {
private long userID; private String userName; private Date birth;
public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public Date getBirth() { return birth; } public void setBirth(Date birth) { this.birth = birth; } public long getUserID() { return userID; } public void setUserID(long userID) { this.userID = userID; } }
Contoller @RequestMapping(value="/user/{userid}") public String queryUser(@PathVariable("userid") long userID, ModelMap model) {
User u = new User(); u.setUserID(userID); u.setUserName("zhaoyang"); model.addAttribute("User", u);
return "User"; }
如果是返回text/html，还需要建立个jsp文件 <body> UserName: ${requestScope.User.userID } <br /> Age: ${requestScope.User.userName } </body>
测试结果 json
xml
jsp
