flowable 流程图片中文乱码

1.springboot添加配置类，指定字体类型为宋体

package org.fh.config;

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

/**
 * 说明：Flowable配置
 * 作者：FH Admin
 * from：fhadmin.cn
 */
@Controller
@Configuration
public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
    
    @Override
    public void configure(SpringProcessEngineConfiguration engineConfiguration) {
        engineConfiguration.setActivityFontName("宋体");
        engineConfiguration.setLabelFontName("宋体");
        engineConfiguration.setAnnotationFontName("宋体");
    }
    
}

2. 操作系统字体库，有宋体字体资源。  windows操作系统基本都有宋体，linux等一般没有，需要自行添加
