我有一个SpringBoot2Gradle项目,我希望将其作为(不可执行的)war文件部署到Tomcat7实例(RHEL)中。
我收到一个
NoClassDefFoundError
向服务器上的Tomcat部署战争时:

在检查时,我发现HibernateBean验证库找不到这个特定的类(
javax.el.ElManager
)初始化期间。
解决方案
here
建议向运行时添加正确的EL API v3.0依赖项,但我不确定这是一个明智的解决方案,因为EL API v2.2已经存在于共享的(
providedRuntime
在格拉德尔的地方图书馆里。我很担心
ClassLoader
如果我有相同API的两个版本(这是合理的考虑吗?).
升级到tomcat 8是不可行的,因为我们在目前只支持tomcat7的RHEL上运行tomcat7。
如何告诉Spring使用javax el api v2.2?
附加说明
违约
tomcat.version
当依靠弹簧启动时,Tomcat似乎
8.5.31
根据
gradlew dependencies
命令:
+--- org.springframework.boot:spring-boot-starter-tomcat:2.0.2.RELEASE
| +--- javax.annotation:javax.annotation-api:1.3.2
| +--- org.apache.tomcat.embed:tomcat-embed-core:8.5.31
| +--- org.apache.tomcat.embed:tomcat-embed-el:8.5.31
| \--- org.apache.tomcat.embed:tomcat-embed-websocket:8.5.31
据我所知
another post
,设置渐变
ext['tomcat.version']
属性到
7.0.76
(我们的服务器版本)正确解析这些依赖项:
+--- org.springframework.boot:spring-boot-starter-tomcat:2.0.2.RELEASE
| +--- javax.annotation:javax.annotation-api:1.3.2
| +--- org.apache.tomcat.embed:tomcat-embed-core:8.5.31 -> 7.0.76
| +--- org.apache.tomcat.embed:tomcat-embed-el:8.5.31 -> 7.0.76
| \--- org.apache.tomcat.embed:tomcat-embed-websocket:8.5.31 -> 7.0.76
| \--- org.apache.tomcat.embed:tomcat-embed-core:7.0.76
但是我还是碰到这个
NoClassDeffoundError(无激光效果错误)
. 在我看来,Spring无法识别正确的API版本,并继续假设
ElManager
存在。
谢谢你抽出时间来。
