需求：
1、springmvc返回xml；
技术及环境：
- Spring 4.3.1.RELEASE
- JDK 1.8
- IDEA 15.0.6
- Maven 3
实现：
spirngxml的配置主要如下：
添加项目依赖：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>4.3.1.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-beans -->

实体类JavaBean
一个简单的JavaBean，添加了JAXB 注解，spring将会根据请求判断转换成xml。JAXB不需要添加额外的依赖库，已经包含在jdk中。
BaseXmlResult 的作用是作为返回的标志和附加消息对象（如：操作成功！操作失败等）。抽取出来，不用每个返回对象都写code和message，只需要继承即可。
XmlActionResult 为具体的要返回的信息的对象。前台页面需要解析的数据。该对象中Data为泛型对象，返回时，可根据实际情况，设置Person.class|Man.class|Woman.class对象，若有其他对象，只需对注解进行调整即可，方便维护。
public class BaseXmlResult {
protected String code;
protected String message;
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
@XmlRootElement(name = "xml")
@XmlAccessorType(XmlAccessType.NONE)
public class XmlActionResult<T> extends BaseXmlResult{ @XmlElements({
@XmlElement(name="Person",type = Person.class),
@XmlElement(name="Man",type = Man.class),
@XmlElement(name="Woman",type = Woman.class)
})
private T data; public String getCode() {
return code;
} public void setCode(String code) {
this.code = code;
} public String getMessage() {
return message;
} public void setMessage(String message) {
this.message = message;
} public T getData() {
return data;
} public void setData(T data) {
this.data = data;
} }
@XmlRootElement
@XmlAccessorType(XmlAccessType.NONE)
public class Person { @XmlElement
private String name;
@XmlElement
private Integer sex;
@XmlElement
private Integer age; private Date birthday; public Person(String name, Integer sex, Integer age) {
this.name = name;
this.sex = sex;
this.age = age;
} public Person() {
} public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} public Integer getSex() {
return sex;
} public void setSex(Integer sex) {
this.sex = sex;
} public Integer getAge() {
return age;
} public void setAge(Integer age) {
this.age = age;
} @JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")//json格式返回的日期格式化注解，日期格式json转换默认是long类型的，如：144101141111111，格式化成yyyy-MM-dd HH:mm:ss格式
public Date getBirthday() {
return birthday;
} public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}
Controller类
@Controller
@RequestMapping("/mvc")
public class HelloController { @RequestMapping("/helloXmlPerson/{name}")
@ResponseBody
public XmlActionResult helloXmlPerson(@PathVariable("name") String name){
XmlActionResult<Person> actionResult = new XmlActionResult<Person>();
actionResult.setCode("123");
actionResult.setMessage(name);
Person person = new Person("xxxxx",1,32); actionResult.setData(person);
return actionResult;
}
}
spring配置文件中新增
<mvc:annotation-driven/>
用于启用@ResponseBody注解。
访问对应得路径后返回：
<xml>
<code>123</code>
<message>nihao</message>
<Person>
<name>xxxxx</name>
<sex>1</sex>
<age>32</age>
</Person>
</xml>
