解决方法：
在tomcat的安装目录下找到\conf\catalina.properties文件并打开，找到tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\，修改为：
tomcat.util.scan.StandardJarScanFilter.jarsToSkip=\,*
2、tomcat配置指定版本的jdk
在tomcat安装目录下打开\bin\setclasspath.bat（Windows）或\bin\setclasspath.sh（Linux）文件，添加配置：export JAVA_HOME=/usr/java/jdk1.7.0_80，export JRE_HOME=/usr/java/jdk1.7.0_80/jre，如下：
# Unless required by applicable law or agreed to in writing, software
# distributed under the License is distributed on an "AS IS" BASIS,
# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
# See the License for the specific language governing permissions and
# limitations under the License.
export JAVA_HOME=/usr/java/jdk1.7.0_80
export JRE_HOME=/usr/java/jdk1.7.0_80/jre
# -----------------------------------------------------------------------------
# Set JAVA_HOME or JRE_HOME if not already set, ensure any provided settings
# are valid and consistent with the selected start-up options and set up the
# endorsed directory.
# -----------------------------------------------------------------------------
