[SPRING] java.lang.ClassNotFoundException : org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

java.lang.ClassNotFoundException : org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

나는 내 프로젝트에서 스프링 통합을 사용하고있다. 부두 컨테이너에 앱을 배포 할 때 다음 예외가 발생합니다.

클래스 패스에는 json jackson-core-asl-1.8.3과 jackson-core-2.3.1 항아리가 있습니다. 여전히 오류가 발생합니다. 문제를 해결하는 방법?

해결법

1. ==============================

   1.흥미로운 것은 com.dsths.common.container.ContainerClassLoader ...입니다.

   흥미로운 것은 com.dsths.common.container.ContainerClassLoader ...입니다.

   스프링 통합 -http가이 ClassLoader에 의해로드되지만 MappingJackson2HttpMessageConverter와 다른 모든 스프링 웹 클래스가 다른 ClassLoader와로드 된 것처럼 보입니다.

   모든 스프링 용기를 같은 클래스 로더에 넣으면 좋을 것입니다.

   앱이 클래스 경로에서 MappingJackson2HttpMessageConverter를 찾을 수 없습니다. 문제는 하나의 클래스 로더가 하나의 버전을 선택하고 다른 클래스 로더가 다른 버전을 선택하는 것입니다.

2. ==============================

   2.이 이상한 오류도 있었어. 나는 웹 서버 (tomcat) webapps / myapp / WEB-INF / lib의 항아리에서 검색을 수행했으며 클래스는 거기에있었습니다.

   이 이상한 오류도 있었어. 나는 웹 서버 (tomcat) webapps / myapp / WEB-INF / lib의 항아리에서 검색을 수행했으며 클래스는 거기에있었습니다.

   직장에서 또 다른 프로젝트를보고 같은 잭슨 병을 사용했을 때 사라졌습니다.

   원래 나는 다음과 같은 것을 가지고 있었다.

   jackson-core-2.4.3.jar
   jackson-databind-2.4.3.jar
   

   나는 이것을 제거하고 다음을 추가했다 (WEB-INF / lib에 패키지 됨) :

   jackson-mapper-asl-1.9.13.jar
   jackson-datatype-jsr310-2.5.0.jar
   jackson-datatype-joda-2.5.0.jar
   jackson-databind-2.5.0.jar
   jackson-core-2.5.0.jar
   jackson-annotations-2.5.0.jar
   

   저는 Windows에서 Tomcat 7을 실행하고 있습니다. Java 1.6 사용 (Tomcat에서 컴파일 및 런타임 용)

   servlet.xml :

   <beans:bean id="jacksonMessageConverter"  
       class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" >
   </beans:bean>
   
       <beans:bean  class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
           <beans:property name="messageConverters">
               <beans:list>
                   <beans:ref bean="jacksonMessageConverter" />
               </beans:list>
           </beans:property>
       </beans:bean>   
   

   도움이 될 경우, jats를 검색하기 위해 cygwin에서 다음 쉘을 실행합니다.

   JAR="C:/java/Java/jdk1.7.0_71/bin/jar.exe"
   srchdir="c:/appservers/apache-tomcat-7.0.57/webapps/my-web/WEB-INF/lib"
   
   echo "SEARCH FOLDER: $srchdir"
   find  $srchdir -print | grep '\.jar$' | while read f
   do
       $JAR tf $f | grep 'MappingJackson2HttpMessageConverter\.class' >/dev/null 2>&1
       [ $? -eq 0 ] && echo "==> $f" && $JAR tf $f | grep MappingJackson2HttpMessageConverter\.class
   done
   

3. ==============================

   3.일반적으로, MappingJackson2HttpMessageConverter 클래스는 spring-web.jar (또는 spring-web-x.y.z-RELEASE.jar)에 존재하므로 classpath에 추가하거나 maven을 사용하여 다음과 같은 의존성을 추가해야합니다.

   일반적으로, MappingJackson2HttpMessageConverter 클래스는 spring-web.jar (또는 spring-web-x.y.z-RELEASE.jar)에 존재하므로 classpath에 추가하거나 maven을 사용하여 다음과 같은 의존성을 추가해야합니다.

   <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-web</artifactId>
       <version>x.y.z.RELEASE</version>
   </dependency>
   

   Artem Bilan 주석 편집 :

   일반적으로 maven을 사용한다면, 스프링 통합 -http의 의존성으로 존재해야한다.
