07点睛Spring MVC4.1-ContentNegotiatingViewResolver - 汪云飞记录本 - ITeye技术网站
博客分类：
7.1 ContentNegotiatingViewResolver
ContentNegotiatingViewResolver支持在Spring MVC下输出不同的格式;
ContentNegotiatingViewResolver是ViewResolver的一个实现;
ContentNegotiatingViewResolver使用request的媒体类型,根据扩展名选择不同的view输出不同的格式;
ContentNegotiatingViewResolver不是自己处理view,而是代理给不同的ViewResolver来处理不同的
本例演示根据扩展名获得不同的页面;
view:WEB-INF/views/demoObj.jsp
viewResolver:UrlBasedViewResolver或InternalResourceViewResolver
view:PdfView
viewResolver:PdfViewResolver
view:MappingJackson2JsonView
viewResolver:JsonViewResolver
view:MarshallingView
viewResolver:XmlViewResolver
view:XlsView
viewResolver:XlsViewResolver

Spring3：如何配置ContentNegotiatingViewResolver返回JSON或者XML格式数据？
首先，我们回顾下，在基于Spring的RESTful的项目中如果你使用这种形式的URL：
http://localhost:8888/myapp/service/xxx/{id}
那么一般情况下，你会被导向到一个HTML页面。如果你想让它返回一个JSON格式或者XML格式的数据，那么你不得不在前台做一番格式转换的处理。
现在，你只需要在你的spring-servlet.xml文件里面配置一下就可以了。
先看配置：
&?xml version="1.0" encoding="UTF-8"?&
&beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

21行：viewResolver的顺序
22行：是一个格式化的开关，类似http://localhost:8888/myapp/service/{id}?format=json这种
23行：忽略请求头中的Accept
25行：默认的数据返回格式
26行~31行：配置媒体类型与扩展名的映射关系，也即将Content-Type=application/json的内容映射到http://localhost:8888/myapp/service/{id}.json这种格式
32行~42行：配置你的ViewResolver
42行~60行：配置数据格式的转换器
数据格式的转换器部分，需要说的是，在spring的包里面有2个不同的类：
org.springframework.web.servlet.view.json.MappingJacksonJsonView
org.springframework.web.servlet.view.json.MappingJackson2JsonView
这两个类对应到pom.xml文件是不同的包，先说第一个：
用第一个类你的JSON解析器是这样的：
&dependency&
&groupId&org.codehaus.jackson&/groupId&
&artifactId&jackson-core-asl&/artifactId&
&version&1.9.13&/version&
&/dependency&
&dependency&
&groupId&org.codehaus.jackson&/groupId&
&artifactId&jackson-mapper-asl&/artifactId&
&version&1.9.13&/version&
&/dependency&
&dependency&
&groupId&org.codehaus.jackson&/groupId&
&artifactId&jackson-jaxrs&/artifactId&
&version&1.9.13&/version&
&/dependency&
用第二个类你的JSON解析器是这样的：
&dependency&
&groupId&com.fasterxml.jackson.core&/groupId&
&artifactId&jackson-core&/artifactId&
&version&2.2.2&/version&
&/dependency&
&dependency&
&groupId&com.fasterxml.jackson.core&/groupId&
&artifactId&jackson-databind&/artifactId&
&version&2.2.2&/version&
&/dependency&
&dependency&
&groupId&com.fasterxml.jackson.core&/groupId&
&artifactId&jackson-annotations&/artifactId&
&version&2.2.2&/version&
&/dependency&
此外，我配置的XML解析器是：
org.springframework.oxm.jaxb.Jaxb2Marshaller
如果你使用JAXB来绑定，那么你的entity类的annotation是这样的：
package com.homeland.myapp.
import java.io.S
import javax.persistence.C
import javax.persistence.E
import javax.persistence.GeneratedV
import javax.persistence.GenerationT
import javax.persistence.Id;
import javax.persistence.SequenceG
import javax.persistence.T
import javax.xml.bind.annotation.XmlE
import javax.xml.bind.annotation.XmlRootE
@Table(name = "employee")
@XmlRootElement(name = "employee")
public class Employee implements Serializable {
private static final long serialVersionUID = -6785130L;
@SequenceGenerator(name = "seq_employee_id",
allocationSize = 1, initialValue = 1,
sequenceName = "seq_employee_id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seq_employee_id")
@Column(name = "first_name", length = 60, nullable = false)
@Column(name = "last_name", length = 60, nullable = false)
@Column(name = "full_name", length = 120, nullable = false)
@Column(name = "age", length = 3, nullable = false)
@Column(name = "sex", length = 1, nullable = false)
@Column(name = "email", length = 255, nullable = false)
@Column(name = "cell_phone", length = 15, nullable = false)
@Column(name = "department_id", nullable = false)
private int
departmentId;
@Column(name = "role_id", nullable = false)
private int roleId;
public Employee() {}
public int getId() {
@XmlElement
public void setId(int id) {
public String getFirstname() {
@XmlElement
public void setFirstname(String firstname) {
this.firstname =
public String getLastname() {
@XmlElement
public void setLastname(String lastname) {
this.lastname =
public String getFullname() {
@XmlElement
public void setFullname(String fullname) {
this.fullname =
public int getAge() {
@XmlElement
public void setAge(int age) {
this.age =
public int isSex() {
@XmlElement
public void setSex(int sex) {
this.sex =
public int getSex() {
public String getEmail() {
@XmlElement
public void setEmail(String email) {
this.email =
public String getCellphone() {
@XmlElement
public void setCellphone(String cellphone) {
this.cellphone =
public int getDepartmentId() {
return departmentId;
@XmlElement
public void setDepartmentId(int departmentId) {
this.departmentId = departmentId;
public int getRoleId() {
return roleId;
@XmlElement
public void setRoleId(int roleId) {
this.roleId = roleId;
这里必须要说一下，如果你把@XmlElement放在property上面，会报错。这个很莫名其妙。根据错误信息，它判定有两个同名的属性，我猜测是因为在扫描文件的时候把方法也扫了。不知道为啥。所以，就把@XmlElement放在了setter()方法上。
但是，我们知道还有另外一个很好用的就是XStream解析器。
那么，如何使用XStream的话，配置文件要如何改呢？

相对应的entity类的annotation也要改：
package com.homeland.myapp.

@SequenceGenerator(name = "seq_employee_id",
allocationSize = 1, initialValue = 1,
sequenceName = "seq_employee_id")

@XStreamAlias("cell_phone")

@XStreamAsAttribute
@XStreamAlias("department_id")
private int
departmentId;
@Column(name = "role_id", nullable = false)
@XStreamAsAttribute
@XStreamAlias("role_id")
private int roleId;
public Employee() {}
public int getId() {
public void setId(int id) {
public String getFirstname() {
public void setFirstname(String firstname) {
this.firstname =
public String getLastname() {
public void setLastname(String lastname) {
this.lastname =

public void setFullname(String fullname) {
this.fullname =
public int getAge() {
public void setAge(int age) {
this.age =
public int isSex() {
public void setSex(int sex) {
this.sex =
public int getSex() {
public String getEmail() {
public void setEmail(String email) {
this.email =
public String getCellphone() {
public void setCellphone(String cellphone) {
this.cellphone =
public int getDepartmentId() {
return departmentId;
public void setDepartmentId(int departmentId) {
this.departmentId = departmentId;
public int getRoleId() {
return roleId;
public void setRoleId(int roleId) {
this.roleId = roleId;
不过，用JAXB以及XStream其返回的数据样式也不完全一样。大家可以比较一下。
在使用Spring3自带的XStreamMarshaller的时候，你会发现如果你用了下划线("_")来链接属性名中的两个或多个单词的话，在最终的xml返回值中出现了双下划线("__")。
目前还不知道怎么解决。网上搜索了下，貌似要换marshaller了。当然，你也可以不用。以下告诉你，用好@XStreamAliases会让返回的XML好看一些：

在上面代码中注释部分相当于加了annotation的entity类：

@Table(name = "employee")
@XStreamAlias("employee")
public class Employee implements Serializable {
private static final long serialVersionUID = -6785130L;
@SequenceGenerator(name = "seq_employee_id",
allocationSize = 1, initialValue = 1,
sequenceName = "seq_employee_id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seq_employee_id")
@XStreamAlias("id")

@Column(name = "department_id", nullable = false)
@XStreamAlias("department-id")
private int
departmentId;
@Column(name = "role_id", nullable = false)
@XStreamAlias("role-id")
private int roleId;
public Employee() {}
public int getId() {
public void setId(int id) {
public String getFirstname() {
public void setFirstname(String firstname) {
this.firstname =
public String getLastname() {
public void setLastname(String lastname) {
this.lastname =
public String getFullname() {
public void setFullname(String fullname) {
this.fullname =
public int getAge() {
public void setAge(int age) {
this.age =
public int isSex() {
public void setSex(int sex) {
this.sex =
public int getSex() {
public String getEmail() {
public void setEmail(String email) {
this.email =
public String getCellphone() {
public void setCellphone(String cellphone) {
this.cellphone =

return departmentId;
public void setDepartmentId(int departmentId) {
this.departmentId = departmentId;
public int getRoleId() {
return roleId;
public void setRoleId(int roleId) {
this.roleId = roleId;
双下划线神马的，换成短线(“-")吧！
JSON格式的返回结果：
{"employee":{
"firstname":"Jackson",
"lastname":"Tom",
"fullname":"tom.jackson",
"email":"tom.",
"cellphone":"86186xxxxxxx8",
"departmentId":11,
"roleId":11
XML格式的返回结果：
