解决方案：

在tomcat配置文件catalina.sh文件中添加 CATALINA_OPTS="-Djava.awt.headless=true"

catalina.sh添加之后如下：

# LOGGING_CONFIG (Optional) Override Tomcat's logging config file

# Example (all one line)

# LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties"

#

# LOGGING_MANAGER (Optional) Override Tomcat's logging manager

# Example (all one line)

# LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"
