Spring Boot与Activiti整合后,查看流程图乱码问题

tangxiong0 2015-11-25

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();
    }
