解决方案
服务器安装宋体
yum install fontconfig
fc-cache --force
然后重启java程序
若是docker部署，需要在docker镜像内部安装。
四、后端启动时报错：找不到或无法加载主类 top.tangyh.lamp.OauthServerApplication

五、SQL执行时，参数值被替换
问题描述
传递的参数： AAA_BBB、 AAA%BBB
执行SQL时变成：AAA\_BBB、 AAA\%BBB
原因
因为_ 和% 是mysql的模糊查询关键字，模糊查询时，Wraps会自动将关键字进行替换。
如下图，entityname字段中有2条数据，分别是“B组招聘人员”和“B组招聘_员”，当前端传递“B组招聘_员”进行查询时，会将2条数据都查出来。
