Spring 3.x MVC 入门3-1 -- 使用内容协商来实现多视图 示例
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
