声明servlet为
provided
<dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope></dependency>
要么
<dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>servlet-api</artifactId> <version>2.5-20081211</version> <scope>provided</scope></dependency>
并从titan中排除servlet
<dependency> <groupId>titan</groupId> <artifactId>titan</artifactId> <exclusions> <exclusion> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </exclusion> </exclusions></dependency>
