jsonView InternalResourceViewResolver 설정,velocity( Spring 4, IntelliJ)

다른 블로그에서는 분명

<bean class="org.springframework.web.servlet.view.BeanNameViewResolver" id="viewResolver" p:order="0">

2	<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" id="jsonView">

3	<property name="contentType" value="application/json;charset=UTF-8">

4	</property></bean>

5

</bean>

이렇게 사용하라고 했지만

 

결론은...

 

HTTP Status 500 - Servlet.init() for servlet bbs threw exception

500에러가 발생한다

그 이유는 

 

<dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-databind</artifactId>
 <version>2.7.3</version>
</dependency>
<dependency>
 <groupId>com.fasterxml.jackson.dataformat</groupId>
 <artifactId>jackson-dataformat-xml</artifactId>
 <version>2.7.3</version>
</dependency>
<dependency>
 <groupId>commons-logging</groupId>
 <artifactId>commons-logging</artifactId>
 <version>1.2</version>
</dependency>
<dependency>
 <groupId>javax.servlet</groupId>
 <artifactId>javax.servlet-api</artifactId>
 <version>3.1.0</version>
</dependency>

 

dependency를 넣지 않아서도 아니고

 

<bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
 <property name="resourceLoaderPath" value="/WEB-INF/vm/"/>
</bean>

<bean id="velocityViewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
 <property name="suffix" value=".vm"/>
</bean>

<bean class="org.springframework.web.servlet.view.BeanNameViewResolver" id="viewResolver"/>
<bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView" id="jsonView">
 <property name="contentType" value="application/json;charset=UTF-8">
 </property>
</bean>

왠지 velocity와 같이 사용해서 인 것같다....

 

그래서 다른블로그들 말만 믿고 에러만 쳐다보다가

결국 찾은 ViewResolver가 바로

 

<bean id="beanNameResolver" class="org.springframework.web.servlet.view.BeanNameViewResolver"/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"/>

 

바로 InternalResourceViewResolver

이 분이다. 에러는 커녕 너무 잘 돌아가줘서 고맙다
