需求：

1、springmvc返回xml；

技术及环境：

  1. Spring 4.3.1.RELEASE
  2. JDK 1.8
  3. IDEA 15.0.6
  4. 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 -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-beans</artifactId>
      <version>4.3.1.RELEASE</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>4.3.1.RELEASE</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework/spring-web -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>4.3.1.RELEASE</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>4.3.1.RELEASE</version>
    </dependency>

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 =http://www.mamicode.com/ 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>
