XML을 출력하자

1. 설정파일을 셋팅해보자. 혼자 삽질하면서 만들었기 때문에 틀린 부분이 있다면 제보바란다.

Web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xmlns="http://java.sun.com/xml/ns/javaee" 

xmlns:jsp="http://java.sun.com/xml/ns/javaee/jsp" 

xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 

id="WebApp_ID" version="2.5">

  <display-name>RESTful</display-name>

<!-- Spring Dispatcher Servlet //-->

<servlet>

<servlet-name>spring3</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>

/WEB-INF/WasSetting/spring/spring3-servlet.xml

</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>spring3</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<!-- //Spring Dispatcher Servlet -->

</web-app> 

설정파일을 따로 관리해보기 위해 경로를 바꾸었다.

spring3-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="

    http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

        ">

<!-- Configures Spring MVC -->

<import resource="spring3mvc-config.xml" />

<!-- Configures Spring MVC -->

<import resource="rest-servlet.xml" />

</beans>

설정을 따로 하기 위해 import를 이용했다.

 spring3mvc-config.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns:context="http://www.springframework.org/schema/context"

    xsi:schemaLocation="

    http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

        http://www.springframework.org/schema/context

        http://www.springframework.org/schema/context/spring-context-3.0.xsd

        ">

<!-- 패키지의 하위 bean 자동 등록 -->

<context:component-scan base-package="test" />

<!-- 뷰어를 연결 -->

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">

<property name="viewResolvers">

   <list>

       <bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/>

       <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">

<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>

<property name="prefix" value="/WEB-INF/jsp/"/>

<property name="suffix" value=".jsp"/>

</bean>

   </list>

</property>

</bean>

</beans>

 패키지 자동 등록의 경우에는 패키지가 커지면 로딩시간도 느려지므로 필요한 패키지를 따로 등록하면 로딩속도가 개선된다.

rest-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="

http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context 

http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<!-- To enable @RequestMapping process on type level and method level -->

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

<!-- xml autodectAnnotation set -->

<bean id="xmlClass" class="org.springframework.web.servlet.view.xml.MarshallingView">

  <property name="marshaller">

     <bean class="org.springframework.oxm.xstream.XStreamMarshaller">

        <property name="autodetectAnnotations" value="true"/>

     </bean>

  </property>

</bean>

</beans> 

xml을 화면에 뿌려주기 위한 설정이다.


2. 이제 클래스를 만들어보자. 테스트를 하기위해 DO와 Controller를 만들어보았다. test페키지에 만들자.

TestDO.java

@XStreamAlias("testdo")

public class TestDO {

private String name;

private int value;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getValue() {

return value;

}

public void setValue(int value) {

this.value = value;

}

} 

 

TestXmlController.java

@Controller

public class TestXmlController{

@RequestMapping(method=RequestMethod.GET,value = "/test/xml")

public ModelAndView newListXml(HttpServletRequest request) {

TestDO testdo = new TestDO();

testdo.setName("테스트 점수");

testdo.setValue(100);

List<TestDO> test = new ArrayList<TestDO>();

test.add(testdo);

return new ModelAndView("xmlClass", "testdo", test);

}

}

3. 출력된 결과를 보자

<list>

<testdo>

<name>테스트 점수</name>

<value>100</value>

</testdo>

</list>
