我有一个基于JDK8, Tomcat7 (V2.1)， Jersey(2.35)和CDI-Weld (2.48 . final)的web应用程序
自从我开始web容器，我收到这个异常总是两次。这两个例外将每5分钟出现一次。我想tomcat有没有超时?
第一个异常将以ERROR Allocate exception for servlet package.RestApplication
第二个带有:ERROR StandardWrapper.Throwable
下面两种情况下的堆栈是相同的，如下所示:

对于焊缝/CDI，我添加了:
<dependency>
<groupId>org.jboss.weld</groupId>
<artifactId>weld-core</artifactId>
<version>2.4.8.Final</version>
</dependency>
<dependency>
<groupId>org.jboss.weld</groupId>
<artifactId>weld-spi</artifactId>
<version>2.4.Final</version>
</dependency>
<dependency>
<groupId>org.jboss.weld</groupId>
<artifactId>weld-api</artifactId>
<version>2.4.Final</version>
</dependency>
<dependency>
<groupId>org.jboss.weld.servlet</groupId>
<artifactId>weld-servlet</artifactId>
<version>2.4.8.Final</version>
</dependency>
对于Jersey，我添加了:
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>
<version>2.35</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>2.35</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-sse</artifactId>
<version>2.35</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-sse</artifactId>
<version>2.35</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.inject</groupId>
<artifactId>jersey-hk2</artifactId>
<version>2.35</version>
</dependency>
而且这些:
<dependency>
<groupId>org.glassfish.jersey.containers.glassfish</groupId>
<artifactId>jersey-gf-cdi</artifactId>
<version>2.14</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.containers.glassfish</groupId>
<artifactId>jersey-gf-ejb</artifactId>
<version>2.35</version>
</dependency>
有人看到不兼容吗?有人知道为什么会出现这种例外吗?还是缺少任何依赖项?
解决这个问题的方法有很多。
一种可能性是更改为BOM并删除所有其他球衣依赖
<dependency>
<groupId>org.glassfish.jersey</groupId>
<artifactId>jersey-bom</artifactId>
<version>2.35</version>
<type>pom</type>
</dependency>
优点
- 更少的依赖关系
BOMmakes "single"非常好的定制依赖
缺点:
