2024 이클립스 스프링 MVC 프로젝트 만들기(2)

 

내가 참고한 https://wildeveloperetrain.tistory.com/m/347 를 보면

기본적인 pom.xml 설정 및 web.xml, root-context.xml, servlet-context.xml 에 대해 나와있다. 

그러나 내가 소개할 방법은 JDBC는 mysql을 사용하고, 컨트롤러에서 기본페이지 띄우는 것 까지 진행할 예정이니 참고하길 바란다. 

 

 

(1) 2024 이클립스 스프링 MVC 프로젝트 만들기(1) 까지 완료하면 pom.xml이 생성되는데, 여기에 <properties>와 <dependencies> 부분만 따로 추가한다. 전체 내용은 아래와 같다.

(2) '프로젝트 우클릭' -> 'Maven' -> 'Update Project 실행

참고한 블로그에 따르면 J가 S로 바뀐다고 했지만 나는 바뀌지 않아서 그냥 그대로 진행했다.

(3) web.xml, root-context.xml, servlet-context.xml 생성

이 셋은 경로 src > main > webapp > WEB-INF에 new file로 생성한다.

 

 

(4) web.xml을 작성한다.

아래는 내가 작성한 전문이다. 

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

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

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

xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"

version="4.0">

 

<display-name>Spring MVC</display-name>

<!-- Root context -->

<context-param>

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

<param-value>/WEB-INF/root-context.xml</param-value>

</context-param>

 

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

 

 

<!-- servlet context -->

<servlet>

<servlet-name>appServlet</servlet-name>

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

<init-param>

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

<param-value>/WEB-INF/servlet-context.xml</param-value>

</init-param>

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

 

</servlet>

<servlet-mapping>

<servlet-name>appServlet</servlet-name>

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

</servlet-mapping>

 

<!-- encoding filter -->

<filter>

<filter-name>encodingFilter</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

</init-param>

</filter>

<filter-mapping>

<filter-name>encodingFilter</filter-name>

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

</filter-mapping>

</web-app>

 

(5) root-context.xml 작성

아래는 내가 작성한 전문이다

페이지만 띄울꺼기 때문에 상관없었지만 DB 연결은 해놓기 위해 dataSource 부분까지 남작성하였다.

<?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"

xmlns:mybatis="http://mybatis.org/schema/mybatis-spring"

xsi:schemaLocation="http://www.springframework.org/schema/beans

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

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

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

http://mybatis.org/schema/mybatis-spring

http://mybatis.org/schema/mybatis-spring-2.0.xsd">

 

<!--classpath:에 나의 db정보를 입력해놓는다. 그럼 이로코롬 가져올 수 있음. 그냥 생성안하고 바로 입력해서 사용해도 됨.

-->

<!--<context:property-placeholder location="classpath:application.properties"/>-->

<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource">

<property name="driverClassName" value="org.mariadb.jdbc.Driver" />

<property name="url" value="jdbc:mysql://localhost:3306/woncoding?useUnicode=true&amp;characterEncoding=utf8" />

<property name="username" value="root" />

<property name="password" value="비밀번호" />

 

</bean>

</beans>

 

(6)servlet-context.xml 을 작성한다

<?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:mvc="http://www.springframework.org/schema/mvc"

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

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

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

<!-- 컴포넌트 스캔 -->

<context:component-scan base-package="com.study.spring"/>

 

<!-- @Controller에 요청을 보내기위한 핸들러매핑과 핸들러댑터를 빈으로 등록함. commpnent-scan 명시하면 이태그 포함 안해도됨 -->

<mvc:annotation-driven/>

 

<mvc:default-servlet-handler />

 

 

<!-- Process annotations on registered beans like @Autowired @Qualifier -->

<context:annotation-config/>

 

<!-- 이건 맨 앞에 써야함. -->

<bean id="viewResolver"

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

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

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

</bean>

 

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">

<property name="messageConverters">

<list>

<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

<property name="supportedMediaTypes">

<list>

<value>text/html;charset=UTF-8</value>

<value>application/json;charset=UTF-8</value>

</list>

</property>

</bean>

</list>

</property>

</bean>

 

<!--한글 깨짐-->

<mvc:annotation-driven>

<mvc:message-converters>

<bean class="org.springframework.http.converter.StringHttpMessageConverter">

<property name="supportedMediaTypes">

<list>

<value>text/plain;charset=UTF-8</value>

<value>text/html;charset=UTF-8</value>

<value>application/json;charset=UTF-8</value>

</list>

</property>

</bean>

</mvc:message-converters>

</mvc:annotation-driven>

</beans>

 

(7) 위와같이 작성을 하면 다시 pom.xml에 </dependencies>안에  아래 내용을   추가 해야한다!  Mybatis와 mysql, json사용을 위한 convert를  추가했다.
