Spring Boot整合Activiti，查看流程图出现中文乱码问题

最近研究SpringBoot 整合Activiti时，实现流程图高亮追踪是出现中文乱码问题，找了很多方法，现在把我最后的解决方法提供给大家。

Spring Boot是微服务快速开发框架，强调的是零配置，显然不推荐采用XML配置文件的方式解决。不使用Spring Boot的时候，

是通过下面这种方式就可以解决

①原始解决方式：在Spring配置文件中的

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">

中加入两行代码：

<property name="activityFontName" value="宋体"/>

<property name="labelFontName" value="宋体"/>

配置如下：

<bean id="processEngineConfiguration"
class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="activityFontName" value="宋体"/>
<property name="labelFontName" value="宋体"/>
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseSchemaUpdate" value="true" />
<property name="mailServerHost" value="localhost" />
<property name="mailServerPort" value="5025" />
<property name="jpaHandleTransaction" value="true" />
<property name="jpaCloseEntityManager" value="true" />
<property name="jobExecutorActivate" value="false" />
</bean>

②Spring Boot中我采用的解决办法是，生成流程图的时候设置字体和编码信息解决，如下

public void genPic(String procId) throws Exception {
ProcessInstance pi = this.processEngine.getRuntimeService().createProcessInstanceQuery()
.processInstanceId(procId).singleResult();
BpmnModel bpmnModel = this.processEngine.getRepositoryService().getBpmnModel(pi.getProcessDefinitionId());
List<String> activeIds = this.processEngine.getRuntimeService().getActiveActivityIds(pi.getId());
ProcessDiagramGenerator p = new DefaultProcessDiagramGenerator();
InputStream is = p.generateDiagram(bpmnModel, "png", activeIds, Collections.<String> emptyList(), "宋体", "宋体",
null, 1.0);

File file = new File("d:\\Download\\process.png");
OutputStream os = new FileOutputStream(file);

byte[] buffer = new byte[1024];
int len = 0;
while ((len = is.read(buffer)) != -1) {
os.write(buffer, 0, len);
}

os.close();
is.close();
}
