因项目需要,将springmvc和hbase整合,启动tomcat时报错如下:
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

根据报错原因推断是jackson的jar包冲突了,于是通过myeclipse看maven依赖结构图:
经过分析是spring中有对jackson-mapper-asl的方法的引用,且1.0.1版本中不具备该方法,由于包冲突导致spring调用的是1.0.1版本中的方法,于是报错。
解决方案:在项目的POM文件中将:
<!-- hadoop相关包 -->
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-core</artifactId>
<version>1.0.4</version>
</dependency>
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase</artifactId>
<version>0.94.7</version>
</dependency>
更改为:
<!-- hadoop相关包 -->
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-core</artifactId>
<version>1.0.4</version>
<exclusions>
<exclusion>
<artifactId>jackson-mapper-asl</artifactId>
<groupId>org.codehaus.jackson</groupId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.hbase</groupId>
<artifactId>hbase</artifactId>
<version>0.94.7</version>
</dependency>
也就是移出低版本的jar包,问题解决!重启tomcat,正常启动!
