Flowable 生成工作流图片时, 不显示文字显示方框

解决方案：
在包扫描的包下面创建一个生成的流程图配置类

package cn.stylefeng.guns.modular.flowable.config;

import org.flowable.spring.SpringProcessEngineConfiguration;
import org.flowable.spring.boot.EngineConfigurationConfigurer;
import org.springframework.context.annotation.Configuration;

/**

 * @Description: 为放置生成的流程图中中文乱码
 * @Date: Create in 2019/11/03 10:26
 */
@Configuration
public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
    @Override
    public void configure(SpringProcessEngineConfiguration springProcessEngineConfiguration) {
        springProcessEngineConfiguration.setActivityFontName("宋体");
        springProcessEngineConfiguration.setLabelFontName("宋体");
        springProcessEngineConfiguration.setAnnotationFontName("宋体");
    }
}

如果是linux，安装相应的字体即可
Linux 中文无法显示或显示方块
