1、在springmvc.xml中加上
1 <!-- 多视图的支持 -->
2 <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
3 <property name="contentNegotiationManager">
4 <bean class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"/>
5 </property>
6 <property name="mediaTypes">
7 <map>
8 <entry key="json" value="application/json"/>
9 <entry key="xml" value="application/xml"/>
10 </map>
11 </property>
12 <property name="defaultViews">
13 <list>
14 <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"/>
15 <bean class="org.springframework.web.servlet.view.xml.MarshallingView">
16 <constructor-arg>
17 <bean class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
18 <property name="classesToBeBound">
19 <list>
20 <value>com.xiaostudy.domain.User</value>
21 </list>
22 </property>
23 </bean>
24 </constructor-arg>
25 </bean>
26 </list>
27 </property>
28 </bean>
2、在支持多视图的类中加上注释@XmlRootElement
1 package com.xiaostudy.domain;
2
3 import javax.xml.bind.annotation.XmlRootElement;
4
5 @XmlRootElement
6 public class User {
7
8 private int id;
9 private String username;
10 private String password;
11 private int age;
12
13 public int getId() {
14 return id;
15 }
16
17 public void setId(int id) {
18 this.id = id;
19 }
20
21 public String getUsername() {
22 return username;
23 }
24
25 public void setUsername(String username) {
26 this.username = username;
27 }
28
29 public String getPassword() {
30 return password;
31 }
32
33 public void setPassword(String password) {
34 this.password = password;
35 }
36
37 public int getAge() {
38 return age;
39 }
40
41 public void setAge(int age) {
42 this.age = age;
43 }
44
45 @Override
46 public String toString() {
47 return "User [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]";
48 }
49
50 }
3、使用
1 package com.xiaostudy.controller;
2
3 import org.springframework.stereotype.Controller;
4 import org.springframework.web.bind.annotation.RequestMapping;
5
6 import com.xiaostudy.domain.User;
7
8 @Controller//<bean class="com.xiaostudy.controller.MyController"/>
9 @RequestMapping(value="/myController")//访问该类的方法时，前面多这样一个路径
10 public class MyController {
11
12 @RequestMapping("multiView")
13 public User multiView() {
14 User user = new User();
15 user.setId(2018);
16 user.setUsername("xiaostudy");
17 user.setPassword("123456");
18 user.setAge(23);
19 return user;
20 }
21
22 }
4、访问
