解决方案:

1. 符合windows下的字体文件, 因为缺少的是宋体, 那么就将宋体, 复制到服务器上

2. 进入jsp项目的classes目录下 
[root@myroot ~]# cd /usr/share/tomcat/webapps/myproject/WEB-INF/classes/
[root@myroot classes]# ls
applicationContext.xml  com  config.properties  ehcache-hibernate.xml  log4j.xml

3. 复制刚才上传的字体文件到该目录下
[root@myroot classes]# cp ~/SIMSUNB.TTF .
l[root@myroot classes]# ls
applicationContext.xml  com  config.properties  ehcache-hibernate.xml  log4j.xml  SIMSUNB.TTF

4. 编辑一个jasperreports.properties文件
[root@myroot classes]# vim  jasperreports.properties
在该文件中输入以下内容:

net.sf.jasperreports.awt.ignore.missing.font=true

5. 重启tomcat服务

[root@myroot ~]# systemctl restart tomcat.service
