- [Spring App Migration: From XML to Java-based Config](http://www.robinhowlett.com/blog/2013/02/13/spring-app-migration-from-xml-to-java-based-config/)

web.xml 에서 context-param 은 아래와 같다. 
```xml
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
            /WEB-INF/spring/context-*.xml
        </param-value>
	</context-param>
```
contextConfigLocation 과 Dispacher 설정이 필요하다.

<mvc:annotation-driven> to @EnableWebMVC

XML namespaces를 대체하는 애노테이션
|<context:component-scan>|@CompnentScan|
|<tx:annotation-driven/>|@EableTransactionManagement|
|<mvc:annotation-driven/>|@EnableWebMvc|
|<aop:aspectj-autoproxy/>|@EnableAspectAutoProxy|

@Import를 사용한 Java Config 설정 불러오기
```java
@Import(DataAccessConfig.class)
=================================
public class DataAccessConfig{...}
```

@ComponentScan 으로 빈 자동 등록하기
```java
@ComponentScan(basePackages = "petclinic.service")
=================================
<context:componet-scan base-package="petclinic.servcei"/>
```

@EnableWebMvc 으로 Spring MVC 설정
```java
@EnableWebMvc
==========================================
<mvc:annotation-driven/>
```

@EnableWebMvc 가 등록하는 빈들
```java
@EnalbeWebMvc
// HandlerMapping
// HandlerAdpater
// ContentNegotiationManager
// HttpMessageConverters
// ConversionService(Converter, Formatter)
// etc
```

#### XMl 빈 정의 메타정보 구조

- WebApplicationContext
  - WEB mvc-web-config.xml
- WebApplicationContext
  - API mvc-api-config.xml
- RootWebApplicationContext
  - Service business-config.xml
  - Repository data-access-config.xml
  - Tools tools-config.xml
  - DataSource datasource-config.xml

#### XML 설정 파일별로 Java Config Class 정의

|WEB|mvc-web-config.xml|→|MvcWebConfig.java|
|API|mvc-api-config.xml|→|MvcApiConfig.java|
|Service|business-config.xml|→|BusinessConfig.java|
|Repository|data-access-config.xml|→|DataAccessConfig.java|
|DataSrouce|datasource-config.xml|→|DatasourceConfig.java|
|Tools|tools-config.xml|→|ToolsConfig.java|


#### ApplicationContext 를 관리하는 web.xml



web.xml이 필요한가?
필요하면 어떤 설정을 해줘야 하는가?
